CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a divisional of U.S. patent application
Ser. No. 09/902,348, which was filed on Jul. 10, 2001, and which in
turn claims the benefit of U.S. Provisional Application Ser. No.
60/243,561, filed Oct. 26, 2000 and entitled "Providing Multiple
Perspectives for a Venue Activity through an Electronic Hand Held
Device." U.S. patent application Ser. No. 09/902,348 and U.S.
Provisional Application Ser. No. 60/243,561 are therefore
incorporated herein by reference in their entireties.
TECHNICAL FIELD
[0002] Embodiments are related to wireless electronic hand held
devices such as Personal Digital Assistants (PDAs), hand held
televisions, and data-enabled wireless telephones. Embodiments also
relate to techniques for remotely delivering video-related data to
hand held devices. In addition, embodiments relate to techniques
for providing increased viewing opportunities for audiences in
venue environments such as stadiums and concert arenas.
Additionally, embodiments relate to wireless video data
transmission to hand held devices.
BACKGROUND OF THE INVENTION
[0003] Most modern stadiums and live entertainment facilities or
arenas (herein also collectively referred to as "venues"), which
feature sporting events and concerts, typically employ large
television screens that receive video images and are linked within
the stadium to a plurality of television cameras positioned to
capture video images at diverse locations within the stadium. The
audience at a typical sporting event, for example, can generally
view advertisements, instant replays, and other sports related data
on the large television screens within the sports stadium itself.
Feeds are additionally generally provided from the cameras to
announcers in a broadcast booth, replaying certain plays from the
event so that announcers can make comments about plays, and finally
transmitting a telecast to the viewing audience, including some
aspects of captured video and data to the stadium audience.
[0004] Despite the availability of such large screen television
monitors, venue event audience members still lack enhanced viewing
options or perspectives within the venue itself. To compensate for
the lack of viewing options, sports and concert promoters often
rent binoculars to audience members prior to or during the event.
Such binoculars can permit the typical audience member to obtain a
somewhat better, but limited, view of the event such as a football
or hockey game, but even these views are often obstructed by other
audience members and are tied to only one perspective.
[0005] The large television screens placed in a venue such as a
stadium are typically linked to cameras that are fixed or mobile.
Placement of cameras about the stadium is generally tied to an
enterprise system. The movement of the game ball in a football
game, for example, along with the players on the field is dynamic
and unpredictable, and may not always be caught by the active
camera having the best perspective. Thus, during a game, the large
television screens typically provide only one view, which can be
further obstructed by other players or officials, often destroying
a critical angular view.
[0006] In addition, such large screens are often utilized to
bombard audience members with information such as advertisements,
thereby cutting into venue activity video that venue audience
members might otherwise wish to view such as instant replays, a
current play, or other event data. The audience members, therefore,
essentially view the large screen at the behest of the camera
operator or director and cannot select their own views or camera
angles.
[0007] Based on the foregoing, the present inventors have found
that such limitations in venue environments can be solved through
the use of hand held devices such as PDAs, hand held televisions,
data/video-enabled cellular telephones, and other hand held
wireless video-enabled devices. For example, the recent shift in
the consumer electronics industry from an emphasis on analog
technology to a preference for digital technology is largely based
on the fact that the former generally limits the user to a role of
a passive recipient of information, while the latter is interactive
and allows the user to control what, when, and how he or she
receives and manipulates certain information. This shift in focus
has resulted in the development and increasingly widespread use of
a digital device generically referred to as a "personal digital
assistant" (PDA).
[0008] Hand held computing devices (i.e., hereinafter referred to
as "hand held devices" or "handheld devices") are becoming
increasingly popular for storing and maintaining information.
Although PDAs may be connected to a desktop personal computer or
other PDAs via infrared, direct wire, or wireless communication
links, PDAs and similar hand held devices can be linked to remote
networks such as the Internet, or local wireless resources, such as
RF broadcasts, through available wireless communications
techniques.
[0009] The most advanced data- and video-enabled wireless
communication devices currently available in the marketplace take
the form of a PDA (e.g., Palm Pilot.TM., Handspring Visor.TM., and
Windows CE compatible hand held computers such as the iPAQ.TM.).
Unlike personal computers, which are general-purpose devices geared
toward refining and processing information, PDAs are designed to
capture, store, and display information originating from various
sources. Additionally, while a certain level of skill is required
to use a personal computer effectively, PDAs are designed with the
novice and non-computer user in mind.
[0010] Attempts have been made to provide venue-based, interactive
entertainment to enhance the fan experience at live events. Such
attempts utilize touch-screen technology integrated directly into
seats at outdoor or indoor arenas. Audience members, however, due
to their integration with the viewer seat, can easily damage such
devices. Systems that incorporate such devices are also expensive
because they literally require miles of cable.
[0011] Some recently constructed arenas, for example, that
implement such seat-integrated technology are requiring hundreds of
miles of electronic cabling including audiovisual, broadcast, and
multiband lines. Such a plethora of large cables are expensive and
require extra space, which often cannot be found in older stadiums,
or would require a greater expense to integrate into newly built
stadiums. The cost of retrofitting an older stadium with such
technology can be staggering. Additionally, many fans that attend
games or concerts with such technology integrated directly into the
seats may find such a feature distracting.
[0012] Another problem faced by venue promoters and arena owners
who integrate fixed technology directly into the seat is that such
technology can quickly become obsolete. If a new facility is fitted
with such electronic/hardware intensive technology, the technology
may become quickly outdated, requiring an expensive update and/or
retrofit.
[0013] The present inventors thus realize that a solution to these
problems lies in the use of wireless hand held devices. By
utilizing modern technology integrated with hand held devices,
on-demand live action, multiple camera angles, instant replays, and
real-time team and venue information may each be readily provided
to fans without the expense and problems associated with present
in-seat integrated technical environments. Additionally, it is
anticipated that the deployment of venue-based systems facilitating
the use of such devices would be relatively inexpensive, at least
in comparison to seat-integrated systems. Finally, such systems
will provide the venue attendee with increased mobility and freedom
of use within and throughout the venue environment.

DETAILED DESCRIPTION
[0043] The particular values and configurations discussed in these
non-limiting examples can be varied and are cited merely to
illustrate one or more embodiments and are not intended to limit
the scope thereof.
[0044] FIG. 1 depicts a schematic diagram illustrating a general
hardware configuration of a hand held device 11, in accordance with
the disclosed embodiments. Those skilled in the art can appreciate,
however, that other hardware configurations with less or more
hardware and/or modules may be utilized in carrying out the methods
and systems (e.g., hand held device 11) of the disclosed
embodiments as further described herein. CPU 10 of hand held device
11 performs as a main controller operating under the control of
operating clocks supplied from a clock oscillator. CPU 10 may be
configured, for example, as a 16-bit microprocessor. External pins
of CPU 10 are generally coupled to an internal bus 26 so that it
may be interconnected to respective components.
[0045] SRAM 24 can be configured as a writeable memory that does
not require a refresh operation and can be generally utilized as a
working area of CPU 10. SRAM (Static RAM) 24 is generally a form of
semiconductor memory (RAM) based on a logic circuit known as a
flip-flop, which retains information as long as there is enough
power to run the device. Font ROM 22 can be configured as a read
only memory for storing character images (e.g., font) displayable
on a display 18. Examples of types of displays that may be utilized
in accordance with display 18 include a TFT active matrix display,
an illuminated LCD (Liquid Crystal Display), or other small-scale
displays being developed.
[0046] CPU 10 of the present embodiment drives display 18
utilizing, among other media, font images from Font ROM 22, and
images transmitted as data through wireless unit 17 and processed
by image-processing module 35. An EPROM 20 may be configured as a
read only memory that is generally erasable under certain
conditions and can be utilized for permanently storing control
codes for operating respective hardware components and security
data, such as a serial number.
[0047] An IR controller 14 can generally be configured as a
dedicated controller for processing infrared codes
transmitted/received by an IR transceiver 16 and for capturing the
same as computer data. Wireless unit 17 can generally be configured
as a dedicated controller and transceiver for processing wireless
data transmitted from and to a wireless communications network.
Note that wireless unit 17 can be implemented as a separate module
or cartridge, such as illustrated in FIG. 3. Wireless unit 17 can
thus comprise a wireless module.
[0048] Port 12 can be connected to CPU 10 and can be temporarily
attached, for example, to a docking station to transmit information
to and from hand held device 11 to other devices such as personal
computers, retail cash registers, electronic kiosk devices, and so
forth. Port 12 can also be configured, for example, to link with a
modem, cradle or docking station, which are well known in the art,
that permit network devices, a personal computer or other computing
devices to communicate with hand held device 11.
[0049] User controls 32 permit a user to enter data to hand held
device 11 and initiate particular processing operations via CPU 10.
A user interface 33 may be linked to user controls 32 to permit a
user to access and manipulate hand held device 11 for a particular
purpose such as, for example, viewing images on display 18. Those
skilled in the art will appreciate that user interface 33 may be
implemented as a touch screen user interface, as indicated by the
dashed lines linking display 18 with user interface 33. In
addition, CPU 10 may cause a sound generator 28 to generate sounds
of predetermined frequencies from a speaker 30. Speaker 30 may be
utilized to produce music and other audio information associated
with video data transmitted to hand held device 11 form an outside
source.
[0050] Those skilled in the art can appreciate that additional
electronic circuits or the like other than, or in addition to,
those illustrated in FIG. 1 may be used to construct hand held
device 11. Such components, however, are not described in the
present specification because many aspects of them are well known
in the art. For example, hand held televisions are available for
receiving public television broadcasts, but the basic technology
can be modified on such devices so that they may be adapted to
(e.g., proper authentication, filters, security codes, or the like)
receive venue-based RF transmissions from at least one venue-based
RF source (e.g., a wireless camera, or data from a camera
transmitted wirelessly through at least one transmitter). Those
skilled in the art can thus appreciate that because of the brevity
of the drawings described herein, only a portion of the connections
between the illustrated hardware blocks is generally depicted. In
addition, those skilled in the art will appreciate that hand held
device 11 can be implemented as a specific type of a hand held
device such as a Personal Digital Assistant (PDA), paging device,
WAP-enabled mobile phone, and other associated hand held computing
devices well known in the art.
[0051] Given the teaching of various embodiments, it should be
appreciated that a hand held device 11 can be configured to permit
images, similar to television broadcast images, to be displayed on
display 18 for a user to view. Hand held device 11 thus includes an
image-processing unit 35 for processing images transmitted as data
to hand held device 11 through wireless unit 17. A tuner unit 34,
implemented as either a single tuner or a plurality of tuners, may
be linked through internal bus 26 to CPU 10. Additionally, a
security unit 36 may be utilized to process proper security codes
to thereby ensure that data transferred to and from hand held
device 11 may be secure and/or permitted. Broadcast security
prevents general receipt of venue images without proprietary
hardware and/or signals.
[0052] Security unit 36 may be implemented as an optional feature
of hand held device 11. Security unit 36 can also be configured
with software, e.g., algorithm routines or subroutines, that are
processed by CPU 10, and which prevent wireless data from being
transmitted/received from hand held device 11 beyond a particular
frequency range, outside of a particular geographical area
associated with a local wireless network, or absent authorization
codes (e.g., decryption, encryption, coding, decoding, and so
forth). Note that security unit 36 can be implemented as a separate
security module such as, for example, a smart card, or cartridge.
An example of a module, which may be implemented in accordance with
the disclosed methods and systems, is illustrated in FIG. 3. A
security module of this type may be utilized for securing data
transmitted from or to a hand held device such as, for example,
hand held device 11.
[0053] Hand held device 11 can thus be configured with both
wireless and wireline capabilities, depending on the needs and
requirements of a manufacturer or customer. Such wireless
capabilities include features such as those found in cellular
telephone units, in accordance with carrying out embodiments.
Current examples of hand held devices that can be utilized in
accordance with the disclosed methods and systems include, for
example, the "PalmPilot.TM." PDA, manufactured and sold by Palm
Computing, the Handspring Visor.TM., Window CE.TM. compatible
devices, RIM.TM. Blackberry-family paging devices, Motorola paging
devices, hand held portable televisions, and the Symbol.TM.
SPT-family of PDA-type organizer devices. Such hand held devices
are mentioned herein for illustrative purposes only and are not
considered limiting features of the disclosed embodiments. Hand
held devices which may also be implemented in accordance with the
methods and systems of the disclosed embodiments include hand held
devices such as cellular telephones having viewable display screens
for the display of data transmitted through wireless networks.
Customized, venue-specific devices (i.e., proprietary, limited use)
may be also developed in accordance with the methods and systems of
the disclosed embodiments that incorporate hardware and software
modules necessary to practice the methods and systems taught
herein.
[0054] Those skilled in the art can appreciate that although hand
held device 11 is generally illustrated in FIG. 1, hand held device
11 can be implemented as a wireless application protocol (WAP)
web-enabled cellular hand held device such as a PDA, wireless
telephone, or pager or a combination thereof. Hand held device 11
can also be configured with features of combination cellular
telephone/PDA devices. One recent example of such a device is the
Handspring.TM. PDA and associated cellular phone attachment module,
which is manufactured and sold by Handspring.TM. Inc. Other such
devices include the Palm-Motorola phone, which permits users to
access e-mail and store calendars and contact databases. Hand held
devices may also be provided in the form of a multi-RF (Radio
Frequency) receiver-enabled hand held television-viewing device
such as those manufactured by Sony.TM. and Casio.TM.. Regardless of
the type of hand held device implemented, it is anticipated that
such hand held devices will be adapted to receive and process data
via image-processing unit 35 for ultimate display as moving images
on display unit 18, in accordance with the disclosed embodiments.
Image-processing unit 35 may include image-processing routines,
subroutines, software modules, and so forth, to perform
image-processing operations.
[0055] FIG. 2 illustrates a pictorial representation of a hand held
device 40 that may be utilized to implement embodiments. Hand held
device 40 includes a display screen 42, which is generally
analogous to display 18 of FIG. 1. Television images broadcast via
radio frequency or digital data may be displayed on display screen
42 for a user to view. User controls 44 can permit a user to select
and/or manipulate images or text displayed on display screen 42.
User controls 44 of FIG. 2 are generally analogous to user controls
32 of FIG. 1. A touch screen user interface may be further
configured on the display screen 42 with hand held device 40 to
permit a user to manipulate images/text displayed on display screen
42.
[0056] FIG. 3 depicts a pictorial representation of a hand held
device 56 adapted for receiving a module 50, in accordance with the
disclosed embodiments. Although hand held device 56 of FIG. 3 is
generally analogous to hand held device 40 of FIG. 2, the
difference being that hand held device 56 may be adapted to receive
a module/cartridge that permits hand held device 56 to function
according to specific hardware, codes and/or instructions contained
in a memory location (e.g., a computer chip or magnetic strip)
within module 50. Module 50 can be configured as a smart card, well
known in the art. Such a smart card may provide, for example,
access codes (e.g., decryption) to enable hand held device 56 to
receive venue broadcasts. Note that as utilized herein, the term
"module" may refer to a physical module such as a cartridge. The
term "module" may also refer to a software module composed of
routines or subroutines that perform a particular function. Those
skilled in the art can appreciate the meaning of the term module is
based on the context in which the term is utilized and environment
being described. Thus, module 50 as illustrated can be generally
configured as a physical cartridge or smart card. The term "module"
as utilized herein may also refer to a software module, depending
on the context of the discussion thereof.
[0057] To illustrate the use of a physical module, such as module
50, assume that a user may possess several such physical modules or
cartridges. One module, when inserted into hand held device FIG. 3
may instruct hand held device 50 to function as a standard PDA such
as a Palm Pilot device. Another module, when inserted into hand
held device FIG. 3, may instruct hand held device 56 to function as
a portable television that receives wireless television broadcasts
and/or data from a local wireless broadcast network and/or
venue-based (e.g., short range) broadcasts. Such a module can also
incorporate decryption capabilities to receive controlled/secured
broadcasts at venues.
[0058] Those skilled in the art can thus appreciate that hand held
device 56 can be adapted to receive and cooperate with module 50.
Additionally, hand held device 56 includes a display screen 52 that
is generally analogous to display screen 42 of FIG. 2 and display
18 of FIG. 1. Hand held device 56 also includes user controls 54
that are generally analogous to user controls 44 of FIG. 2 and user
controls 32 of FIG. 1. Hand held device 56 of FIG. 3 is generally
analogous to hand held device 11 of FIG. 1. Thus, hand held device
56 can also implement touch screen capabilities through a touch
screen user interface integrated with display screen 52.
[0059] Assuming module 50 is implemented as a smart card instead of
a cartridge to provide receiver and/or securing capabilities (e.g.,
encryption, decryption, coding, decoding, etc.), it is anticipated
that similar features can be implemented in accordance with a smart
card to insure that hand held device 56 includes touch screen user
interface and video viewing capabilities. Smart cards are generally
known in the art as credit card sized plastic cards with an
embedded computer chip. The chip can either be a microprocessor
with internal memory or a memory chip with non-programmable logic.
The chip connection can be configured via direct physical contact
or remotely through a contactless electromagnetic interface.
[0060] Smart cards may be generally configured as either a contact
or contactless smart card, or a combination thereof. A contact
smart card requires insertion into a smart card reader (e.g.,
contained within hand held device 56) with a direct connection to,
for example, a conductive micromodule on the surface of the card.
Such a micromodule may be generally gold plated. Transmission of
commands, data, and card status takes place through such physical
contact points.
[0061] A contactless card requires only close proximity to a
reader. Both the reader and the card may be implemented with
antenna means providing a contactless link that permits the devices
to communicate with one another. Contactless cards can also
maintain internal chip power or an electromagnetic signal (e.g., RF
tagging technology). Two additional categories of smart codes, well
known in the art, which are based on contact and contactless cards,
are the so-called Combi cards and Hybrid cards.
[0062] A Hybrid card generally may be equipped with two chips, each
with a respective contact and contactless interface. The two chips
are not connected, but for many applications, this Hybrid serves
the needs of consumers and card issuers. The Combi card may be
generally based on a single chip and can be generally configured
with both a contact and contactless interface.
[0063] Chips utilized in such smart cards are generally based on
microprocessor chips or memory chips. Smart cards based on memory
chips depend on the security of the card reader for their
processing and can be utilized when low to medium security
requirements. A microprocessor chip can add, delete and otherwise
manipulate information in its memory. Microprocessor-based memory
cards typically contain microprocessor chips with 8, 16, and 32 bit
architectures.
[0064] FIG. 4 illustrates a system 58 for providing multiple
perspectives through a hand held device 60 of activities at a venue
80, in accordance with the disclosed embodiments. For illustrative
purposes only, it may be assumed that venue 80 of FIG. 4 is a
stadium venue such as a football stadium. Cameras 71, 73, 75, and
77 can be respectively positioned at strategic points about venue
80 to capture the best images of activity taking place within venue
80. Cameras 71, 73, 75, 77 can be respectively linked to
transmitters 70, 72, 74, and 76. Each of these transmitters may be
configured as equipment, which feeds a radio signal to an antenna
for transmission. The equipment may also provide for the securing
transmission of signals and associated data. For example, such
equipment can rely on the encryption of signals. These signals, if
encrypted, can be decrypted by authorized hand held receivers.
[0065] The antenna may be integrated with the transmitter.
Transmitters are well known in the art and include active
components, such as a driver, well known in the art. Transmitters
also include passive components, such as a TX filter, also well
known in the art. These components, when operating together,
impress a signal onto a radio frequency carrier of the correct
frequency by immediately adjusting its frequency, phase, or
amplitude, thereby providing enough gain to the signal to project
it to its intended target (e.g., a hand held device located within
the venue).
[0066] A hand held device 60 may be held by a user at a stadium
seat within view of the activity at the venue 80. Hand held device
60 is generally analogous to hand held device 11 of FIG. 1 and hand
held device 40 of FIG. 2. Hand held device 60 of FIG. 4 may be
configured as a hand held device (e.g., PDA, portable television,
etc.) adapted for use with a cartridge/module, such as module 50 of
hand held device 56 of FIG. 3. The cartridge/module may contain the
electronics (e.g., tuner(s), filter(s), security codes,
encryption/decryption codes, etc.) to allow a hand held device to
be adapted for receiving venue-based data. Hand held device 60
includes a display screen 61 (e.g. display 18 of FIG. 1).
[0067] Additionally, display screen 61 of hand held device 60 may
be configured with a touch screen user interface displayable and
operable on display screen 61. Those skilled in the art can
appreciate that touch screen interfaces are well known in the PDA
art and further explanation thereof should not be necessary.
Display screen 61 can include a touch screen display area 65 that
may be associated with camera 71. Thus, images captured by camera
71 are transmitted from transmitter 70, which is linked to camera
71. Additionally, display screen 61 includes touch screen display
areas 69, 63, and 67, which can be respectively associated with
cameras 73, 75, and 77.
[0068] Cameras 71, 73, 75, and 77 can be respectively labeled
C.sub.1, C.sub.2, C.sub.3, and C.sub.N to indicate that a plurality
of cameras may be utilized in accordance with system 58 to view
activities taking place within venue 80, such as a football game or
concert. Although only four cameras are illustrated in FIG. 4,
those skilled in the art will appreciate that additional or fewer
cameras may be also implemented in accordance with system 58. Touch
screen display areas 65, 69, 63, and 67 are also respectively
labeled C.sub.1, C.sub.2, C.sub.3, and C.sub.N to illustrate the
association between these display areas and cameras 71, 73, 75, and
77 where touch screen technology is utilized.
[0069] Hand held device 60 can be integrated with one or more
plurality of tuners, as illustrated by tuners 62, 64, 66, and 68.
Such tuners can be activated via user controls on hand held device
60 and/or via touch screen icons or areas displayed on display
screen 61 that are associated with each tuner. Such icons/areas may
be respectively displayed within display areas 65, 69, 63 and 67,
or within a separate display area of display screen 61 (e.g.,
picture-within-picture capabilities found on large television
sets). A user accesses tuner 62, for example, to retrieve real-time
video images transmitted from transmitter 70 for camera 71.
Likewise, a user can access tuner 64 to retrieve real-time video
images transmitted from transmitter 72 for camera 73.
[0070] In addition, a user can access tuner 66 to retrieve
real-time video images transmitted from transmitter 74 for camera
75. Finally, user can access tuner 68 to retrieve real-time video
images transmitted from transmitter 76 for camera 77. In the
example depicted in FIG. 4, a football player 82 is participating
in a football game within venue 80. Cameras 71, 73, 75, and 77
capture moving images (e.g., video data) of the football player 82
from various angles and transmit these images to hand held device
60.
[0071] FIG. 5 depicts a system 59 that provides multiple
perspectives of activity at a venue 80 through a hand held device
60 adapted to receive and process real time video data in
accordance with the disclosed embodiments. Note that in FIG. 4 and
FIG. 5 analogous parts are indicated by identical reference
numerals. Thus, for example, cameras 71, 73, 75, and 77 of FIG. 5
are analogous to cameras 71, 73, 75, and 77 of FIG. 4. Hand held
device 60 of FIG. 5 is also analogous to hand held device 60 of
FIG. 4 and includes similar features thereof.
[0072] Hand held device 60 of FIG. 5, however, can be configured to
receive wireless real time video data transmitted for cameras 71,
73, 75, and 77 respectively through data transmitters 102, 104,
106, and 108 to server 100 and thereafter to wireless data
transmitter/receiver 110. Note that wireless data
transmitter/receiver 110 is analogous to wireless unit 17 of FIG.
1. Hand held device 60 of FIG. 5 is also analogous to hand held
device 11 of FIG. 1.
[0073] Hand held device 60 of FIG. 5 can also incorporate a touch
screen user interface, as described herein with respect to
analogous hand held device 60 of FIG. 4. The difference between
system 58 of FIG. 4 and system 59 of FIG. 5 lies in the inclusion
of digital transmitters 102, 104, 106, and 108 which can be
respectively linked to cameras 71, 73, 75, and 77 of FIG. 5. In the
illustration of FIG. 5, cameras 71, 73, 75, and 77 may be
configured as high definition video cameras which capture real time
images of events or activities taking place within venue 80, such
as real time video footage of football player 82.
[0074] A captured image of football player 82, for example, can be
transferred from one or more of video cameras 71, 73, 75, and 77 of
FIG. 5 and transmitted through a respective digital transmitter
such as digital transmitter 102, 104, 106 or 108 and transmitted
via wired and/or wireless communications to server 100. The server
100 then processes the video data received from one or more of the
digital transmitters and formats the video data for transmission
via wireless means to wireless data transmitter/receiver 100, which
may be integrated with hand held device 100. Transmitter/receiver
100 can communicate with the various components of hand held device
60 such as a CPU, image-processing unit, memory units, and so
forth.
[0075] Those skilled in the art can appreciate that although real
time video data may be transmitted to server 100, captured past
video images may also be stored within server 100 and transferred
to hand held device 60 for display at display screen 61. For
example, instant replays may be transferred as video data to hand
held device 60 upon the request of a user of hand held device 60.
Such instant replay footage can be displayed on display screen 61
for the user to view.
[0076] FIG. 6 illustrates a system 79 for providing multiple
perspectives of activity at a venue 80 through a hand held device
60 adapted to receive and process real time video data from at
least one wide-angle and/or panoramic video camera 114, in
accordance with the disclosed embodiments. In system 79 of FIG. 6,
wide-angle/panoramic (hereinafter referred to as "panoramic") video
camera 114 may be configured as a high-definition panoramic video
camera that captures images of activities taking place at venue 80.
In the example illustrated in FIG. 6, panoramic video camera 114
can capture images of a football game and one or more football
players, such as illustrated football player 82.
[0077] A data transmitter 112 may be linked to panoramic video
camera 114. Video data captured by panoramic video camera 114 may
be transferred to data transmitter 112, which thereafter transmits
the video data to server 100 via a direct link or wireless link,
depending on the needs or requirements of the promoters or venue
owners. Note that this is also true of the system described in FIG.
6. Server 100 of FIG. 6 is analogous to server 100 of FIG. 5. Thus,
in the case of FIG. 5, video data may be transmitted from one or
more of data transmitters 102, 104, 106, and 108 via a direct
wire/cable link or through wireless transmission means, such as
through a wireless network.
[0078] Those skilled in the art will appreciate, of course, that
hand held device 60 of FIG. 6 is analogous to hand held devices
depicted in FIGS. 1-5 herein. In FIGS. 4, 5, and 6, like or
analogous parts are identified by identical reference numerals.
Thus, images captured by panoramic video camera 114 of activity
taking place at venue 80 may be displayed as real time video images
or instant replay data on display screen 61 of hand held device
60.
[0079] FIG. 7 depicts a system 89 for providing multiple
perspectives for activity at a venue 120 at a first time and/or
perspective (Time 1) and a second time and/or perspective (Time 2),
in accordance with the disclosed embodiments. In FIGS. 4, 5, 6, and
7, like or analogous parts are indicated by identical reference
numerals. Thus, in system 89 of FIG. 7, an event, in this case
illustrated as a hockey game, is taking place within venue 120.
Venue 120 may be, for example, a hockey arena. Panoramic video
camera 114 may be linked to data transmitter 112.
[0080] As explained previously, data transmitter 112 may be linked
to server 100 via a direct link such as a transmission cable or
line, or through wireless communication means, such as through a
wireless network. Server 100 can also communicate with hand held
device 60 through a wireless network or other wireless
communication means by transmitting data through such a network or
wireless communications means to wireless data transmitter/receiver
110. Wireless data transmitter/receiver 110, as explained
previously, may be integrated with hand held device 60.
[0081] Thus, a video image 124 of a hockey player 123 can be
captured as video data by panoramic video camera 114, along with a
video image 126 of a hockey player 122 and displayed within display
screen 61 of hand held device 60 as indicated at Time 1. Video
image 124 and 126 can be displayed within a grid-like interface on
display screen 61. Note that in the illustration of FIG. 7, display
screen 61 may be divided into four sections.
[0082] When a user touches, for example the area or section of
display screen 61 in which video image 124 may be displayed, the
entire display area of display screen 61 can then be consumed with
a close-up video shot of video image 124, as indicated at Time 2,
thereby providing the user with a closer view of hockey player 123.
Those skilled in the art can appreciate that the touch screen
display area of display screen 61 can be arranged with graphical
icons and/or user-controls that perform specific pan and zoom
functions. Such icons/user-controls, when activated by a user,
permit the user to retrieve panned/zoomed images of events taking
place in real time within venue 120.
[0083] Note that although only one panoramic video camera 114 and
one data transmitter 112 are illustrated in FIG. 7, a plurality of
panoramic video cameras, servers, and data transmitters may be
implemented in accordance with the disclose embodiments to capture
the best video images, image-processing, and signal capacity to
users, whether real time or otherwise, of events taking place at
venue 120.
[0084] FIG. 8 illustrates a system 92 for providing multiple
perspectives through hand held device 60 of an activity at a venue
130, including the use of a wireless gateway 124, in accordance
with embodiments. Those skilled in the art can appreciate that
wireless gateway 124 may be configured as an access point for a
wireless LAN (Local Area Network). Access points for wireless LAN
networks and associated wired and wireless hardware (e.g., servers,
routers, gateways, etc.) are well known in the art and may be
utilized in accordance with the disclosed embodiments described
herein. Again, note that in FIGS. 4, 5, 6, 7, and 8, like or
analogous parts are indicated by identical reference numerals.
System 92 of FIG. 8 is analogous to system 89 of FIG. 7, the
difference being in the nature of the venue activity. Venue 130 can
be, for example, a concert hall or stadium configured with a sound
stage.
[0085] Gateway 124 can be configured as a communications gateway
through which data may enter or exit a communications network such
as wireless network 152 illustrated in FIG. 9 for a large capacity
of user hand device 60 users. Wireless network 152 may be
configured as a wireless LAN network. Hand held device 60 can be
configured to communicate and receive transmissions from such a
wireless LAN network based on device identification (e.g., device
address). Communication with hand held devices, such as hand held
device 60, however, may also be achieved through RF (Radio
Frequency) broadcasts, thereby not requiring two-way communication
and authentication between, for example, a wireless LAN network and
such hand held devices. A broadcast under such a scenario may also
require that such a hand held device or hand held devices possess
decryption capabilities or the like in order to be authorized to
receive transmissions from the venue.
[0086] The remaining elements of FIG. 8 are also analogous to the
elements depicted in the previous drawings, with the addition of
wireless gateway 124, which may be linked to server 100 and may be
in communication with several wireless data transmitters/receivers
110 and one or more electronic hand held devices, including hand
held device 60. Wireless data transmitter/receiver 110, as
explained previously, may be integrated with hand held device 60.
One or more panoramic video cameras, such as panoramic video camera
114, can be positioned at a venue 130 at locations that capture
images not only of the events taking place on a concert stage, but
also events taking place within the stadium itself.
[0087] If an audience member 140, for example, happens to be
walking along a stadium aisle within view of panoramic video camera
114, the audience member's video image can be displayed as video
image 144 within display screen 61 of hand held device 60, as
indicated at Time 1. Likewise, panoramic video camera 114 captures
images of band member 138 whose video image can be displayed as
video image 142 within a display area of display screen 61, as
indicated at Time 1.
[0088] Thus, a user of hand held device 60 can view not only the
events taking place on a central performing platform of venue 130,
but also other events within the arena itself. The band member 138
may be located on a central performing platform (not shown) of
venue 130 when panoramic video camera 114 captures real-time video
images of band member 138. The user may also, for example, wish to
see a close-up of audience member 140. By activating user controls
and/or a touch screen interface integrated with display screen 61,
the user can, for example, pan or zoom to view a close-up video
shot of audience member 140, as indicated at Time 2.
[0089] Captured video images are transferred from panoramic video
camera 114 as video data through transmitter 112 to server 100 and
through wireless gateway 124 to wireless data transmitter/receiver
110. Although a single server 100 is illustrated in FIG. 8, those
skilled in the art can appreciate that a plurality of servers
and/or wireless gateways can be implemented in accordance with the
methods and systems of the disclosed embodiments to process and
deliver captured and transmitted video data. Based on the
foregoing, those skilled in the art can appreciate that video data
may be simultaneously transferred from server 100 or a plurality or
servers to literally thousands of hand held devices located within
the range of the wireless network and/or wireless gateways
associated with venue 130.
[0090] FIG. 9 illustrates a system 150 for providing multiple
perspectives through hand held device 60 of an activity at a venue
130 in association with a wireless network 152, in accordance with
the disclosed embodiments. System 150 of FIG. 9 is analogous to
system 92 of FIG. 8; the difference is noted in the inclusion of
wireless network 152. Thus, in FIG. 8 and FIG. 9, like or analogous
parts are indicated by identical reference numerals. Video data
captured by a camera or cameras, such as panoramic video camera
114, may be transferred to data transmitter 112, which transmits
the video data to wireless network 152. Wireless network 152 then
retransmits the data, at the request of authorized users of hand
held devices, such as hand held device 60, to wireless data
transmitters/receivers, such as transmitter/receiver 110 integrated
with hand held device 60.
[0091] Those skilled in the art can appreciate that wireless
network 152 may also receive and retransmit other data, in addition
to video data. For example, a server or other computer system may
be integrated with wireless network 152 to provide team and venue
data, which can then be transferred to wireless data transmitter
receiver 110 from wireless network 152 and displayed thereafter as
team and venue information within display screen 61 of hand held
device 60. Other data that may be transferred to hand held device
60 for display include real-time and historical statistics,
purchasing, merchandise and concession information, and additional
product or service advertisements.
[0092] Such data can include box scores, player information and
matchups, animated playbooks, shot/hit/pitch charts, historical
information, and offense-defense statistics. In a concert venue,
for example, as opposed to a sporting event, information pertaining
to a particular musical group can also be transferred to the hand
held device, along with advertising or sponsor information. Note
that both the video data and other data described above generally
comprise types of venue-based data. Venue-based data, as referred
to herein, may include data and information such as video, audio,
advertisements, promotional information, propaganda, historical
information, statistics, event scheduling, and so forth, associated
with a particular venue and/or its advertisers/sponsors generally
not retrievable through public networks.
[0093] Such information can be transmitted together with video data
received from data transmitter 112. Such information may be
displayed as streaming data within display area 61 of hand held
device 60 or simply stored in a database within hand held device 60
for later retrieval by the user.
[0094] One example of a wireless network that may be utilized to
implement wireless network 152 can be Bluetooth, which is described
in greater detail herein, and was conceived originally to make up
for the shortcomings of infrared technologies (IR). Because IR
cannot be utilized to penetrate walls, carry data heavy signals, or
operate within devices that are not in line of sight, Bluetooth,
which is becoming well known in the art, can be configured as or
with wireless network 152.
[0095] FIG. 10 illustrates an entity diagram 170 depicting network
attributes of wireless network 152 that may be utilized in
accordance with the disclosed embodiments. A wireless network 152
as illustrated in FIG. 10 can be configured as a variety of
possible wireless networks. Thus, entity diagram 170 illustrates
attributes of wireless network 152, which may or may not be
exclusive of one another.
[0096] Those skilled in the art can appreciate that a variety of
possible wireless communications and networking configurations may
be utilized to implement wireless network 152. Wireless network 152
may be, for example, implemented according to a variety of wireless
protocols, including cellular, Bluetooth, and 802.11 RF or direct
IR communications. Wireless network 152 can be implemented as a
single network type or a network based on a combination of network
types (e.g., Bluetooth, CDMA, etc).
[0097] Wireless network 152 may be configured with
teachings/aspects of CDPD (Cellular Digital Packet Data) networks
well known in the networking arts. CDPD network 154 is illustrated
in FIG. 10. CDPD may be configured as a TCP/IP based technology
that supports Point-to-Point (PPP) or Serial Line Internet Protocol
(SLIP) wireless connections to mobile devices such as the hand held
devices described and illustrated herein. Mobility and/or cellular
service are generally available throughout the world from major
service providers. Data can be transferred utilizing CDPD
protocols.
[0098] Current restrictions of CDPD are not meant to limit the
range or implementation of the method and system described herein,
but are described herein for illustrative purposes only. It is
anticipated that CDPD will be continually developed and that such
new developments can be implemented in accordance with the
disclosed embodiments.
[0099] Wireless network 152 may preferably be also configured with
teachings/aspects of a Personal Area Network 156 or Bluetooth, as
described herein. Bluetooth was adopted by a consortium of wireless
equipment manufacturers referred to as the Bluetooth Special
Interest Group (BSIG) and has emerged as a global standard for low
cost wireless data and voice communication. Current specifications
for this standard call for a 2.4 GHz ISM frequency band. Bluetooth
technology is generally based on a short-range radio
transmitter/receiver built into small application specific circuits
(ASICS, DSPs) and embedded into support devices such as the hand
held devices described and illustrated herein.
[0100] The Bluetooth standard permits up to 100 mw of power, which
can increase the range to 100 M. In addition, Bluetooth can support
several data channels. Utilizing short data packets and frequency
hopping of up to 1600 hops per second, Bluetooth is a wireless
technology that can be utilized to enable the implementation of the
methods and systems described herein. Current restrictions of
Bluetooth are not meant to limit the range or implementation of the
disclosed embodiments, but are described herein for illustrative
purposes only. It is anticipated Bluetooth will be continually
developed and that such new developments can be implemented in
accordance with the disclosed embodiments.
[0101] Wireless network 152 may also be configured utilizing
teachings/aspects of GSM network 158. GSM (Global System for Mobile
Communication) and PCS (Personal Communications Systems) networks,
both well known in the telecommunications arts, generally operate
in the 800 MHz, 900 MHz, and 1900 MHz range. PCS initiates
narrowband digital communications in the 900 MHz range for paging
and broadband digital communications in the 1900 MHz band for
cellular telephone service. In the United States, PCS 1900 is
generally equivalent to GSM 1900. GSM operates in the 900 MHz,
1800-1900 MHz frequency bands, while GSM 1800 is widely utilized
throughout Europe and many other parts of the world.
[0102] In the United States, GSM 1900 is generally equivalent to
PCS 1900, thereby enabling the compatibility of these two types of
networks. Current restrictions of GSM and PCS are not meant to
limit the range or implementation of the disclosed embodiments, but
are described herein for illustrative purposes only. It is
anticipated that GSM and PCS will be continually developed and that
aspects of such new developments can be implemented in accordance
with the disclosed embodiments.
[0103] Wireless network 152 may also utilize teachings/aspects of
GPRS network 160. GPRS technology, well-known in the
telecommunications arts, bridges the gap between current wireless
technologies and the so-called "next generation" of wireless
technologies referred to frequently as the third-generation or 3G
wireless technologies. GPRS is generally implemented as a
packet-data transmission network that can provide data transfer
rates up to 115 Kbps. GPRS can be implemented with CDMA and TDMA
technology and supports X.25 and IP communications protocols, all
well known in the telecommunications arts. GPRS also enables
features such as Voice over IP (VoIP) and multimedia services.
Current restrictions of GPRS are not meant to limit the range or
implementation of the disclosed embodiments, but are described
herein for illustrative purposes only. It is anticipated that GPRS
will be continually developed and that such new developments can be
implemented in accordance with the disclosed embodiments.
[0104] Wireless network 152 may also be implemented utilizing
teaching/aspects of a CDMA network 162 or CDMA networks. CDMA (Code
Division Multiple Access) is a protocol standard based on IS-95
CDMA, also referred to frequently in the telecommunications arts as
CDMA-1. IS-95 CDMA is generally configured as a digital wireless
network that defines how a single channel can be segmented into
multiple channels utilizing a pseudo-random signal (or code) to
identify information associated with each user. Because CDMA
networks spread each call over more than 4.4 trillion channels
across the entire frequency band, it is much more immune to
interference than most other wireless networks and generally can
support more users per channel.
[0105] Currently, CDMA can support data at speeds up to 14.4 Kbps.
Wireless network 152 may also be configured with a form of CDMA
technology known as wideband CDMA (W-CDMA). Wideband CDMA may also
be referred to as CDMA 2000 in North America. W-CDMA can be
utilized to increase transfer rates utilizing multiple 1.25 MHz
cellular channels. Current restrictions of CDMA and W-CDMA are not
meant to limit the range or implementation of the disclosed
embodiments, but are described herein for illustrative purposes
only. It is anticipated that CDMA and W-CDMA will be continually
developed and that such new developments can be implemented in
accordance with the disclosed embodiments.
[0106] Wireless network 152 may also be implemented utilizing
teachings/aspects of paging network 164. Such paging networks, well
known in the telecommunications arts, can be implemented in
accordance with the disclosed embodiments to enable transmission or
receipt of data over the TME/X protocol, also well known in the
telecommunications arts. Such a protocol enables notification in
messaging and two-way data coverage utilizing satellite technology
and a network of base stations geographically located throughout a
particular geographical region. Paging network 164 can be
configured to process enhanced 2-way messaging applications.
[0107] Unified messaging solutions can be utilized in accordance
with wireless network 152 to permit carriers and Internet service
providers to manage customer e-mail, voice messages and fax images
and can facilitate delivery of these communications to PDAs,
telephony devices, pagers, personal computers, and other capable
information retrieval devices, wired or wireless.
[0108] Current restrictions of such paging networks are not meant
to limit the range or implementation of the disclosed embodiments,
but are described herein for illustrative purposes only. It is
anticipated that such paging networks, including those based on the
TME/X protocol, will be continually developed and that such new
developments can be implemented in accordance with the disclosed
embodiments.
[0109] Wireless network 152 may also be configured utilizing
teachings/aspects of TDMA networks 166. TDMA (Time Division
Multiple Access) is a telecommunications network utilized to
separate multiple conversation transmissions over a finite
frequency allocation of through-the-air bandwidth. TDMA can be
utilized in accordance with the disclosed embodiments to allocate a
discrete amount of frequency bandwidth to each user in a TDMA
network to permit many simultaneous conversations or transmission
of data. Each user may be assigned a specific timeslot for
transmission. A digital cellular communication system that utilizes
TDMA typically assigns 10 timeslots for each frequency channel.
[0110] A hand held device operating in association with a TDMA
network sends bursts or packets of information during each
timeslot. Such packets of information are then reassembled by the
receiving equipment into the original voice or data/information
components. Current restrictions of such TDMA networks are not
meant to limit the range or implementation of the disclosed
embodiments, but are described herein for illustrative purposes
only. It is anticipated that TDMA networks will be continually
developed and that such new developments can be implemented in
accordance with the disclosed embodiments.
[0111] Wireless network 152 may also be configured utilizing
teachings/aspects of Wireless Intelligent Networks (WINs) 168. WINs
are generally known as the architecture of the wireless switched
network that allows carriers to provide enhanced and customized
services for mobile telephones. Intelligent wireless networks
generally include the use of mobile switching centers (MSCs) having
access to network servers and databases such as Home Location
Registers (HLRs) and Visiting Location Registers (VLRs), for
providing applications and data to networks, service providers, and
service subscribers (wireless device users).
[0112] Local number portability allows wireless subscribers to make
and receive calls anywhere--regardless of their local calling area.
Roaming subscribers are also able to receive more services such as
call waiting, three-way calling, and call forwarding. A HLR is
generally a database that contains semi-permanent mobile subscriber
(wireless device user) information for wireless carriers' entire
subscriber base.
[0113] A useful aspect of WINs for the disclosed embodiments is
enabling the maintenance and use of customer profiles within an
HLR/VLR-type database. Profile information may be utilized for
example with season ticket holders and/or fans of traveling teams
or shows. HLR subscriber information as used in WINs includes
identity, service subscription information, location information
(the identity of the currently serving VLR to enable routing of
communications); service restrictions, and supplementary
services/information. HLRs handle SS7 transactions in cooperation
with Mobile Switching Centers and VLR nodes, which request
information from the HLR or update the information contained within
the HLR. The HLR also initiates transactions with VLRs to complete
incoming calls and update subscriber data. Traditional wireless
network design is generally based on the utilization of a single
HLR for each wireless network, but growth considerations are
prompting carriers to consider multiple HLR topologies.
[0114] The VLR may also be configured as a database that contains
temporary information concerning the mobile subscribers currently
located in a given MSC serving area, but whose HLR may be
elsewhere. When a mobile subscriber roams away from the HLR
location into a remote location, SS7 messages are used to obtain
information about the subscriber from the HLR and to create a
temporary record for the subscriber in the VLR.
[0115] Signaling System No. 7 (referred to as SS7 or C7) is a
global standard for telecommunications. In the past, the SS7
standard has defined the procedures and protocol by which network
elements in the public switched telephone network (PSTN) exchange
information over a digital signaling network to affect wireless and
wireline call setup, routing, control, services, enhanced features,
and secure communications. Such systems and standards may be
utilized to implement wireless network 152 in support of venue
customers, in accordance with the disclosed embodiments.
[0116] Improved operating systems and protocols allow Graphical
User Interfaces (GUIs) to provide an environment that displays user
options (e.g., graphical symbols, icons or photographs) on a
wireless device's screen. Extensible Markup Language ("XML") is
generally a currently available standard that performs as a
universal language for data making documents more interchangeable.
XML allows information to be used in a variety of formats for
different devices including PCs, PDAs and web-enabled mobile
phones.
[0117] XML enables documents to be exchanged even where the
documents were created and/or are generally used by different
software applications. XML may effectively enable one system to
translate what another system sends. As a result of data transfer
improvements, wireless device GUIs can be utilized in accordance
with a hand held device and wireless network 152, whether
configured as a paging network or another network type, to render
images on the hand held device that closely represent the imaging
capabilities available on desktop computing devices.
[0118] Those skilled in the art can appreciate that the system and
logical processes described herein relative to FIGS. 11 to FIG. 17
are not limiting features of the disclosed embodiments. Rather,
FIGS. 11 to FIG. 17 provide examples of image-processing systems
and logical processes that can be utilized in accordance with the
disclosed embodiments. Such a system and logical processes
represent one possible technique, which may be utilized in
accordance with one or more embodiments to permit a user of a hand
held device to manipulate video images viewable on a display screen
of the hand held device.
[0119] FIG. 11 thus illustrates a prior art overview display 200
and a detail window 210 that may be utilized with varying
embodiments. The overview image display 200 is a view
representative of a 360.degree. rotation around a particular point
in a space. While a complete rotational view may be utilized in
accordance with the disclosed embodiments, one of ordinary skill in
the computer arts will readily comprehend that a semi-circular pan
(such as used with wide-angle cameras) or other sequence of images
could be substituted for the 360 degree rotation without departing
from the subject invention. The vantage point is generally where
the camera was located as it panned the space. Usually the scene is
captured in a spherical fashion as the camera pans around the space
in a series of rows as depicted in FIG. 12. The space is divided
into w rows 220-224 and q columns 230-242 with each q representing
another single frame as shown in FIG. 12.
[0120] User control over the scene (e.g., rotation, pan, zoom) may
be provided by pressing a touch screen display icon or moving a
cursor displayed on a display screen of a hand held device, such as
the hand held devices described herein. User control over the scene
may also be provided by manipulating external user controls
integrated with a hand held device (e.g., user controls 44 and 54
of FIG. 2 and FIG. 3). Movement from a frame in the overview image
display to another frame is in one of eight directions as shown in
FIG. 13. The user may interact with the video representation of the
space one frame at a time. Each individual frame is an image of one
of the pictures taken to capture the space as discussed above. The
individual frames may be pieced together.
[0121] Interacting with a video one frame at a time results in the
ability to present a detailed view of the space. The user can
experience the overview image display as it unfolds a single frame
at a time. In a venue application, a user may choose to view
different sections of a larger area by browsing to a particular
area that is provided. The area chosen may be at a high resolution
allowing for the user to zoom in and out of the section.
[0122] Another limitation of a simple overview viewer is that there
is no random access means. The frames can only be viewed
sequentially as the overview image display is unfolded. As adapted
for use in accordance with the disclosed embodiments, this problem
has been overcome by providing tools to browse, randomly select,
and trace selected images associated with any overview image.
[0123] FIG. 14 illustrates a prior art overview image 300, a detail
window 310, and a corresponding area indicia, in this case a
geometric figure outline 320. The detail window 310 corresponds to
an enlarged image associated with the area bounded by the geometric
figure outline 320 in the overview image 300. As the cursor is
moved, the location within the overview image 300 may be
highlighted utilizing the geometric figure outline 320 to clearly
convey what location the detail window 310 corresponds to.
[0124] One of ordinary skill in the computer arts will readily
comprehend that reverse videoing the area instead of enclosing it
with a geometric figure would work equally well. Differentiating
the area with color could also be used without departing from the
invention. A user can select any position within the overview
image, press the cursor selection device's button (for example,
user controls in the form of touch screen user interface buttons or
icons), and an enlarged image corresponding to the particular area
in the overview display is presented in the detail window 310.
Thus, random access of particular frames corresponding to the
overview image may be provided.
[0125] FIG. 15 illustrates a prior art series of saved geometric
figure outlines corresponding to user selections in tracing through
an overview display for subsequent playback. The overview image 400
has a detail window 410 with an enlarged image of the last location
selected in the overview image 470. Each of the other cursor
locations traversed in the overview image 420, 430, 440, 450 and
460 are also enclosed by an outline of a geometric figure to
present a trace to the user.
[0126] Each of the cursor locations may be saved and, because each
corresponds to a particular frame of the overview image, the trace
of frames can be replayed at a subsequent time to allow another
user to review the frames and experience a similar presentation.
Locations in the detailed window and the overview image can also be
selected to present other images associated with the image area,
but not necessarily formed from the original image.
[0127] For example, a china teacup may appear as a dot in a china
cabinet, but when the dot is selected, a detailed image rendering
of the china teacup could appear in the detailed window. Moreover,
a closed door appearing in an image could be selected and result in
a detailed image of a room located behind the door even if the room
was not visible in the previous image. Finally, areas in the
detailed window can also be selected to enable further images
associated with the detailed window to be revealed. Details of
objects within a scene are also dependent on resolution
capabilities of a camera. Cameras having appropriate resolution
and/or image processing capabilities are preferably used in
accordance with certain aspects of the disclosed embodiments.
[0128] The overview image was created as discussed above. To assist
one of ordinary skill in the art to make and use the invention, a
more detailed discussion of the necessary processing is presented
below with reference to FIG. 16 and FIG. 17 herein.
[0129] FIG. 16 depicts a prior art flowchart providing a logical
process for building an overview image display. Such a logical
process may be utilized in accordance with the disclosed
embodiments, but is not a necessary feature of the disclosed
embodiments. Those skilled in the art will appreciate that such a
logical process can be merely an example of one type of
image-processing algorithm that may be utilized in accordance with
the disclosed embodiments. For example, such a logical process may
be implemented as a routine or subroutine that runs via
image-processing unit 35 of FIG. 1 in a hand held device. Those
skilled in the art can appreciate that the logical process
described with relation to FIGS. 16 and 17 herein are not limiting
features of the disclosed embodiments.
[0130] Such logical processes, rather, are merely one of many such
processes that may be utilized in accordance with the disclosed
embodiments to permit a user to manipulate video images displayed
via a display screen of a hand held device. Navigable movie/video
data in the form of images input to the hand held device to form
individual images can be thus processed, as illustrated at function
block 500. User specified window size (horizontal dimension and
vertical dimension) may be entered, as illustrated at function
block 504.
[0131] Image variables can be specified (horizontal sub-sampling
rate, vertical sub-sampling rate, horizontal and vertical overlap
of individual frame images, and horizontal and vertical clip (the
number of pixels are clipped from a particular frame in the x and y
plane)), as depicted at function block 508. Function blocks 500,
504, and 508 are fed into the computation function block 510 where
the individual frames are scaled for each row and column, and the
row and column variables are each initialized to one.
[0132] Then a nested loop can be invoked to create the overview
image. First, as indicated at decision block 512, a test is
performed to determine if the maximum number of rows has been
exceeded. If so, then the overview image is tested to determine if
its quality is satisfactory at decision block 520. If the quality
is insufficient, the user may be provided with an opportunity to
adjust the initial variables, as illustrated at function blocks 504
and 508. The processing is then repeated. If, however, the image is
of sufficient quality, it can be saved and displayed for use, as
depicted at block 560.
[0133] If the maximum rows have not been exceeded as detected in
decision block 512, then another test can be performed, as
illustrated at decision block 514, to determine if the column
maximum has been exceeded. If so, then the row variable can be
incremented and the column variable can be reset to one at function
block 518 and control flows to input block 520. If the column
maximum has not been exceeded, then the column variable may be
incremented and the sub-image sample frame can be retrieved, as
depicted at input block 520. Then, as illustrated at function block
530, the frame may be inserted correctly in the overview image.
[0134] The frame may be inserted at the location corresponding to
(Vsub*row*col)+Hsub*col; where row and col refer to the variables
incremented in the nested loop and Vsub and Hsub are user specified
variables corresponding to the horizontal and vertical sub sampling
rate. Finally, the incremental overview image can be displayed
based on the newly inserted frame as depicted at display block 540.
Thereafter, the column variable can be reset to one and processing
can be passed to decision block 512.
[0135] A computer system corresponding to the prior art method and
system depicted in FIGS. 11 to 17 may be generally interactive. A
user may guess at some set of parameters, build the overview image,
and decide if the image is satisfactory. If the image is not
satisfactory, then variables can be adjusted and the image is
recreated. This process can be repeated until a satisfactory image
results, which may be saved with its associated parameters. The
picture and the parameters can then be input to the next set of
logic.
[0136] Such features may or may not be present with the hand held
device itself. For example, images may be transmitted from a
transmitter, such as data transmitter 112 of FIG. 7, and
subroutines or routines present within the server itself may
utilize predetermined sets of parameters to build the overview
image and determine if the image is satisfactory, generally at the
request of the hand held device user. A satisfactory image can then
be transmitted to the hand held device. Alternatively,
image-processing routines present within an image-processing unit
integrated with the hand held device may operate in association
with routines present within the server to determine if the image
is satisfactory, and/or to manipulate the image (e.g., pan,
zoom).
[0137] FIG. 17 depicts a prior art flowchart illustrative of a
logical process for playback interaction. The logical process
illustrated in FIG. 17 may be utilized in accordance with the
disclosed embodiments. Playback interaction may commence, as
illustrated at label 600, which immediately flows into function
block 604 to detect if user controls have been activated at the
hand held device. Such user controls may be configured as external
user controls on the hand held device itself. (e.g., buttons,
etc.), or via a touch screen user interface integrated with hand
held device display screen.
[0138] When a touch screen user input or user control button press
is detected, a test can be performed to determine if a cursor is
positioned in the overview portion of the display. If so, then the
global coordinates can be converted to overview image coordinates
local to the overview image as shown in output block 612. The local
coordinates can be subsequently converted into a particular frame
number as shown in output block 614. Then, the overview image is
updated by displaying the frame associated with the particular
location in the overview image and control flows via label 600 to
function block 604 to await the next button press.
[0139] If the cursor is not detected in the overview image as
illustrated at decision block 610, then another test may be
performed, as indicated at decision block 620, to determine if the
cursor is located in the navigable player (detail window). If not,
then control can be passed back via label 600 to function block 604
to await the next user input. However, if the cursor is located in
the detail window, then as depicted a function block 622, the
direction of cursor movement may be detected. As depicted at
function block 624, the nearest frame can be located, and as
illustrated at decision block 626, trace mode may be tested.
[0140] If trace is on, then a geometric figure can be displayed at
the location corresponding to the new cursor location in the
overview image. The overview image may then be updated, and control
can be passed back to await the next user input via user controls
at the hand held device and/or a touch screen user interface
integrated with the hand held device. If trace is not on, the
particular frame is still highlighted as shown in function block
630, and the highlight can be flashed on the overview image as
illustrated at output block 632. Thereafter, control may be
returned to await the next user input.
[0141] Although the aforementioned logical processes describe the
use of a cursor as a means for detecting locations in a panorama,
those skilled in the art can appreciate that other detection and
tracking mechanisms may be utilized such as, for example, the
pressing of a particular area within a touch screen display.
[0142] FIG. 18 depicts a pictorial representation illustrative of a
Venue Positioning System (VPS) 700 in accordance with the disclosed
embodiments. FIG. 18 illustrates a stadium venue 701, which is
divided according to seats and sections. Stadium venue 701 may be
utilized for sports activities, concert activities, political
rallies, or other venue activities. Stadium venue 701 is divided,
for example, into a variety of seating sections A to N. For
purposes of simplifying this discussion, VPS 700 is described in
the context of sections A to C only.
[0143] A venue positioning system (VPS) device 704 is positioned in
section A of stadium venue 701, as indicated at position A2. A VPS
device 702 is located within section A at position A1. In the
illustration of FIG. 18, it is assumed that VPS device 702 is
located at the top of a staircase, while VPS device 704 is located
at the bottom of the staircase, and therefore at the bottom of
section A, near the sports field. A VPS device 706 is located near
the top of section B at position B1. A VPS device 708 is located at
the bottom of section B at position B2, near the sports field.
Similarly, in section C, venue-positioning devices 710 and 712 can
be respectively located at positions C1 and C2.
[0144] A hand held device 703 may be located at a seat within
section A. For purposes of this discussion, and by way of example
only, it is assumed that hand held device 703 is being operated by
a stadium attendee watching a sporting event or other venue
activity taking place on the sports field. A hand held device 707
is located within section B. Hand held device 707, by way of
example, may also be operated by a concessionaire or venue
employee.
[0145] If the user of hand held device 703 desires to order a soda,
hot dog, or other product or service offered by venue operators
during the venue event, the user merely presses an associated
button displayed via a touch screen user interface integrated with
the hand held device. A signal is transmitted by hand held device
703, in response to the user input to/through the VPS device,
wireless network, or wireless gateway as previously described. One
or more of VPS devices 702, 704, 706, and 708 may detect the
signal. The VPS devices may also operate merely as transponders, in
which case hand held devices will be able to determine their
approximate location within the venue and then transmit position
information through wireless means to, for example, concession
personnel.
[0146] VPS devices 702, 704, 706, and 708 function in concert with
one another to determine the location of hand held device 703
within section A. Triangulation methods, for example, may be used
through the hand held device or VPS devices to determine the
location of the hand held device within the venue. This information
is then transmitted by one or more of such VPS devices either
directly to hand held device 707 or initially through a wireless
network, including a wireless gateway and associated server, and
then to hand held device 707. The user of hand held device 707 can
then proceed directly to the location of hand held device 703 to
offer concession services.
[0147] Additionally, hand held device 703 can be configured with a
venue menu or merchandise list. In response to requesting a
particular item from the menu or merchandise list, the request can
be transmitted as wireless data from hand held device 703 through
the wireless network to hand held device 707 (or directly to a
controller (not shown) of hand held device 707) so that the user
(concession employee) of hand held device 707 can respond to the
customer request and proceed directly to the location of hand held
device 703 used by a customer.
[0148] FIG. 19 illustrates in greater detail the VPS 700 of FIG.
18, in accordance with the disclosed embodiments. Note that in
FIGS. 18-19, identical or similar parts are indicated by identical
reference numerals, unless otherwise stated. Additionally wireless
gateway 124 and server 100 of FIG. 19 are analogous to the wireless
gateway 124 and server 100 illustrated in FIG. 8. Venue positioning
units 702, 704, 706, and 708 are located within section A and
section B. A wireless gateway 124 is linked to server 100. Wireless
gateway 124 can communicate with hand held device 707 and hand held
device 703.
[0149] Wireless gateway 124 can also communicate with VPS devices
702, 704, 706, and 708 if the VPS devices are also operating as
data communication devices in addition to providing mere
transponder capabilities. When VPS devices 702, 704, 706, and 708
detect the location of hand held device 703 within stadium venue
701, the location is transmitted to wireless gateway 124 and
thereafter to hand held device 703. It should be appreciated that a
hand held device user may also identify his/her location in a venue
by entering location information (e.g., seat/section/row) on the
hand held device when making a request to a service provider such
as a food concession operation. The VPS devices will still be
useful to help concession management locate concession employees
located within the venue that are in closest proximity to the hand
held device user. A wireless gateway 124 and server 100 can be
associated with a wireless network implemented in association with
stadium venue 701. Those skilled in the art will appreciate that
such a wireless network may be limited geographically to the
stadium venue 701 itself and the immediate surrounding area. An
example of such a wireless network, as described previously, is a
Bluetooth based wireless network.
[0150] The hand held devices themselves may be proprietary devices
owned by promoters or operators of stadium venue 701 and rented to
patrons for their use while attending a venue activity. Proprietary
devices will generally be manufactured using durable materials
(e.g., similar to those materials used on field technician digital
multimeters/devices such as the Fluke.TM. line of electronic
devices). Proprietary devices will also be limited in hardware and
software modules (i.e., software routines/subroutines) needed for
communication with the venue system in order to display venue
activities to temporary users.
[0151] Hand held devices may also be owned by the patrons
themselves that they bring into the stadium venue for their use by
permission of the venue promoter or stadium owners in return for
the payment of a fee by the patron. In return for the fee, the
venue promoter or stadium owner can provide the patron with a
temporary code, which permits them to access the wireless
transmissions network and associated with the venue itself, such as
wireless network 152 described herein. Patron-owned devices may
utilize modules (e.g., smart card technology to receive
authorization (e.g., frequency or codes) needed to receive
venue--provided video/data. Authorization may also be transferred
to the patron-owned device via IR or short-range RF means. Wireless
network 152 described herein may be configured as a proprietary
wireless Intranet/Internet providing other data accessible by
patrons through their hand held devices.
[0152] FIG. 20 depicts a flowchart of operations illustrative of a
method 740 for providing multiple venue activities through a hand
held device, in accordance with the disclosed embodiments. The
method 740 can be initiated, as depicted at block 742. As
illustrated next at block 744, a venue attendee may activate at
least one hand held tuner integrated with a hand held device, such
as the hand held device illustrated in FIG. 4. At least one tuner
may be integrated with the hand held device, although more than one
tuner (or other simultaneous signal receiving capability) may be
used within a hand held device in support of other embodiments of
the invention previously described.
[0153] The tuner, or tuners, is/are associated with a transmission
frequency/frequencies of a transmitter that may be linked to a
particular camera/cameras focusing on a venue activity, or to a
wireless gateway or wireless network transmission. To view images
from a particular angle, the user can retrieve the video images
from the camera associated with that particular perspective. The
user may have to adjust a tuner until the right frequency/image is
matched, as indicated at block 746. As illustrated at block 748,
captured video images are transferred from the video camera to the
transmitter associated with the camera, or a server in control of
the camera(s). Video images are thus generally transmitted to the
hand held device at the specified frequency, either in response to
a user request at the hand held device, as depicted at block 750 or
as a broadcast.
[0154] An image-processing unit integrated with the hand held
device, as illustrated at block 752, may process transferred video
images. An example of such an image-processing unit is
image-processing unit 35 of FIG. 1. As indicated thereafter at
block 754, the video images of the venue activity captured by the
video camera can be displayed within a display area of the hand
held device, such as display 18 of FIG. 1. The process can then
terminate, as illustrated at block 756, when the user no longer
desires to view the perspective.
[0155] FIG. 21 illustrates a flowchart of operations illustrative
of a method 770 for providing multiple venue activities through a
hand held device from one or more digital video cameras, in
accordance with the disclosed embodiments. When a user of a hand
held device can interact with the venue system, as indicated at
block 772, the process is initiated. As illustrated next at block
774, video images of a venue activity may be captured by one or
more digital video cameras.
[0156] Such digital video cameras may be panoramic/wide-angle in
nature and/or configured as high definition/resolution video
cameras, well known in the art. The video camera, or cameras, may
be respectively linked to data transmitters such as data
transmitters 102, 104, 106, and/or 108 of FIG. 5 or data
transmitter 112 of FIG. 6 to FIG. 9 herein. As depicted next at
decision block 778, if a user does not request a view of the venue
activity through the hand held device, the process terminates
(i.e., with respect to that use), as illustrated thereafter at
block 779.
[0157] If, as illustrated at decision block 778, the user can
request a view of the venue activity through the hand held device,
then as described thereafter at block 780, video data may be
transferred from a data transmitter to a server, such as server 100
of FIG. 5 to FIG. 8 herein. The video data may be stored in a
memory location of the server or a plurality of servers, as
indicated at block 782. The video data may then be transferred to a
wireless data transmitter/receiver integrated with the hand held
device, as indicated at block 784.
[0158] As illustrated thereafter at block 786, the video data may
be processed by an image-processing unit and associated
image-processing routines and/or subroutines integrated with the
hand held device. When image processing is complete, the video
images may be displayed in a display area of the hand held device.
As illustrated next at block 790, if a user chooses to pan/zoom for
a better view of the video images displayed within the hand held
device, then two possible operations may follow, either separately
or in association with one another.
[0159] The image-processing unit integrated with the hand held
device may process a user's pan/zoom request, as illustrated at
block 792. Alternatively, image-processing routines and/or
subroutines resident at the server or a plurality of servers may
process the user's pan/zoom request, following the transmission of
the user's request from the hand held device to the server or
plurality of servers. Such a request may be transmitted through a
wireless gateway linked to the server or servers.
[0160] Image processing may occur at the server or servers if the
hand held device is not capable of directly processing the video
data and video images thereof due to low memory or slow CPU
allocation. Likewise, some image-processing may take place within
the hand held device, while video image-processing requiring faster
processing capabilities and increased memory may take place
additionally at the server or servers to assist in the final image
representation displayed at the hand held device.
[0161] When image processing is complete, the pan/zoomed images can
be displayed within a display screen or display area of the hand
held device, as illustrated thereafter at block 796. The process
then terminates, as depicted at block 798. If the user does not
request pan/zoom, as indicated at block 790, the process may then
terminate, as described at block 791.
[0162] The embodiments and examples set forth herein are presented
in order to best explain the present invention and its practical
application and to thereby enable those skilled in the art to make
and utilize the invention. However, those skilled in the art will
recognize that the foregoing description and examples have been
presented for the purpose of illustration and example only. The
description as set forth is not intended to be exhaustive or to
limit the invention to the precise form disclosed. Many
modifications and variations are possible in light of the above
teaching without departing from the spirit and scope of the
