Description
BACKGROUND
[0001] When a user of an electronic device browses or previews
video files on the device, a video decoder of the device's
operating system (OS) may select multiple frames from each file for
decoding and potential display one of the decoded video frames as a
thumbnail image of the file in question. If the format of the video
file is not natively supported by the OS video decoder, however, a
generic thumbnail image may be displayed, which can prevent the
user from easily determining the content of the underlying video.
Even if the format of the video file is natively supported, the
selected frame for the thumbnail image may not be representative of
the video content (e.g., shows a meaningless scene or portion of a
scene). Moreover, different operating systems may use different
algorithms to select the representative frame, which may lead to
inconsistent results from the perspective of the user.
Additionally, decoding multiple candidate frames for each video
file can increase power consumption and create delays in the
browsing process. Increased power consumption may be particularly
problematic for mobile devices in which battery life is an area of
concern.

DETAILED DESCRIPTION
[0010] Embodiments may include a computer readable storage medium
having a set of instructions which, if executed by a processor,
cause a computer to identify a file containing video content. The
instructions, if executed, may also cause a computer to identify
thumbnail information for the video content, and embed the
thumbnail information into the file containing the video
content.
[0011] Embodiments may also include a method that involves
identifying a file containing video content and identifying
thumbnail information for the video content, wherein the thumbnail
information includes one or more of a representative image and an
index to a key frame in the video content. The method may also
provide for embedding the thumbnail information into the file
containing the video content. If the thumbnail information includes
the representative image, the representative image may be embedded
at a predetermined location in the file. If the thumbnail
information includes the index to a key frame, the index may be
embedded into a header of the file.
[0012] Embodiments may also include a computer readable storage
medium having a set of instructions which, if executed by a
processor, cause a computer to receive a browse request associated
with a file containing video content. The instructions, if
executed, may also cause a computer to identify thumbnail
information in the file and display a thumbnail image based on the
thumbnail information.
[0013] Embodiments may also include a system having a battery to
provide power to the system, and an input module to receive a
browse request associated with a file containing video content. The
system may also include a thumbnail module to identify thumbnail
information in the file, and an output module to display a
thumbnail image based on the thumbnail information.
[0014] Turning now to FIG. 1, an architecture 10 to modify video
files is shown. In the illustrated example, a file 12 contains
video content 14, wherein the video content 14 may include a
plurality frames 16 representing captured scenes, subjects, images,
and so forth, at different moments in time. The file 12 may
therefore be a video clip, video stream, video recording, etc.,
suitable for decoding and display on a display device such as a
monitor, projector, screen, and so forth (not shown). The frames 16
may be encoded according to a video format such as, for example,
MP4 (Moving Picture Experts Group 4 Part 14), AVI (Audio Video
Interleave), 3GP (Third Generation Partnership), etc., wherein no
thumbnail image is incorporated into the video content 14 itself.
Accordingly, a content creator utility 18 (18a-18d) may be used by
a creator/producer of the video content 14 to embed thumbnail
information 20 into the file 12.
[0015] More particularly, the illustrated utility 18 includes a
file module 18a to identify the file 12 and a thumbnail module 18b
to identify the thumbnail information 20. As will be discussed in
greater detail, the thumbnail information 20 may include, for
example, a representative image associated with the video content
14 (e.g., poster, advertisement, trailer, announcement), an index
to one or more key frames (e.g., intra coded frames/I-frames)
within the video content 14, etc., or any combination thereof. The
thumbnail module 18b may work in conjunction with a user interface
(UI) 18c to obtain the thumbnail information 20 based on user
input. The illustrated utility 18 also includes an embed module 18d
that embeds the thumbnail information 20 into the file 12 to obtain
a modified file 22. Of particular note is that the thumbnail
information 20 can enable the video content 16 to be
browsed/previewed without concern over inconsistent results, power
consumption, battery life or delays.
[0016] FIG. 2A shows one approach to a UI 24 of a content creator
utility such as the utility 18 (FIG. 1), already discussed. The
illustrated UI 24, which may be readily substituted for the UI 18c
(FIG. 1), presents multiple key frames 26 (26a, 26b) to the user
and enables the user to select/designate one or more of the key
frames 26 as a source of a thumbnail image, wherein the key frames
26 may be generated via I-frame encoding. In this regard, I-frame
encoding uses predictions that are constrained within the frame
(i.e., predictions do not reference other frames). Thus, I-frame
encoding may be particularly useful for generating thumbnail images
because no other frames may be needed in the decoding process. In
the illustrated example, the user selects a first key frame 26a
that is more representative of the underlying video content 40 than
a second key frame 26b, which conveys very little information to
the viewer by itself (i.e., because the subject is not fully
shown).
[0017] Additionally, an index 28 to the selected key frame 26a may
be added to a header 30 of a file 32 containing the video content
40 so that subsequent file browsers may readily determine which
frame to use as the source of a thumbnail image. Thus, the index 28
may constitute thumbnail information that ensures the same key
frame is used for the thumbnail image regardless of the OS decoder
being used, reduces power consumption because only one key frame is
decoded by the OS decoder, extends battery life, and reduces
display time.
[0018] FIG. 2B shows another approach to a UI 34 of a content
creator utility such as the utility 18 (FIG. 1), already discussed.
The illustrated UI 34, which may be readily substituted for the UI
18c (FIG. 1), enables the user to upload one or more representative
images 36 to be used as a thumbnail image. In the illustrated
example, the user uploads the representative image 36, which may or
may not be an actual scene or frame of the video content 42, into
the utility. The utility may then embed the representative image 36
at a predetermined location in a file 38 containing the video
content 42. The predetermined location may be any location within
the file 38 that is agreed upon by both the encoding/producing
entity and the decoding/displaying entity. The representative image
36 may have a resolution that is different from (i.e., greater or
less than) the resolution of the video content 42, depending upon
the circumstances. Thus, the representative image 36 may constitute
thumbnail information that ensures the same representative image 36
is used for the thumbnail image regardless of the OS decoder being
used, reduces power consumption because no frame decoding is
conducted by the OS decoder, extends battery life, and reduces
display time.
[0019] Turning now to FIG. 3, an architecture 44 to browse/preview
video files is shown. In the illustrated example, a user issues a
browser request 46 associated with a video file 52 to an OS 48
(48a-48d) via a UI 50 (e.g., touch screen interface, keyboard,
keypad, mouse, touch pad, microphone, display, etc.), wherein the
browser request 46 might correspond to the user opening a "gallery"
component of the OS 48 that references the file 52, opening a
folder that contains the file 52, scrolling a file listing that
contains the file 52, and so forth. The OS 48 may include an input
module 48a that receives the browse request 46 and a thumbnail
module 48b that identifies thumbnail information 54 in the file 52,
which contains video content 56.
[0020] In one example, the thumbnail information 54 may include an
index to a key frame in the video content 56, wherein the index is
embedded in a header of the file 52. In such a case, a decoder 48c
of the OS 48 may decode the indexed key frame and an output module
48d of the OS 48 may display a thumbnail image 58 based on the
decoded key frame. In another example, the thumbnail information 54
includes one or more representative images that are embedded at a
predetermined location in the file 52. In such a case, the
thumbnail module 48b may simply retrieve the representative image
and provide it to the output module 48d for display as the
thumbnail image 58. As already noted, the resolution of the
representative image may be different from the resolution of the
video content 56. The thumbnail information 54 may also include
both an index to one or more key frames and one or more
representative images, depending upon the circumstances.
[0021] FIG. 4 shows a method 60 of modifying video files. The
method 60 may be implemented in executable software as a set of
utility logic instructions stored in a machine- or
computer-readable storage medium of a memory such as random access
memory (RAM), read only memory (ROM), programmable ROM (PROM),
firmware, flash memory, etc., in configurable utility logic such
as, for example, programmable logic arrays (PLAs), field
programmable gate arrays (FPGAs), complex programmable logic
devices (CPLDs), in fixed-functionality utility logic hardware
using circuit technology such as, for example, application specific
integrated circuit (ASIC), complementary metal oxide semiconductor
(CMOS) or transistor-transistor logic (TTL) technology, or any
combination thereof. For example, computer program code to carry
out operations shown in method 60 may be written in any combination
of one or more programming languages, including an object oriented
programming language such as Java, Smalltalk, C++ or the like and
conventional procedural programming languages, such as the "C"
programming language or similar programming languages.
[0022] Illustrated processing block 62 provides for identifying a
file containing video content, wherein the file may be a video
clip, stream, recording, and so forth. Thumbnail information may be
identified at block 64. The thumbnail information might include,
for example, an index to one or more key frames in the video
content, one or more representative images, etc., or any
combination thereof. Block 66 may embed the thumbnail information
into the file.
[0023] FIG. 5 shows a method 70 of browsing/previewing video files.
The method 70 may be implemented in executable software as a set of
preview logic instructions stored in a machine- or
computer-readable storage medium of a memory such as RAM, ROM,
PROM, firmware, flash memory, etc., in configurable preview logic
such as, for example, PLAs, FPGAs, CPLDs, in fixed-functionality
preview logic hardware using circuit technology such as, for
example, ASIC, CMOS or TTL technology, or any combination thereof.
Illustrated processing block 72 provides for receiving a browse
request associated with a file containing video content, wherein
thumbnail information may be identified in the file at block 74.
The thumbnail information might include, for example, an index to
one or more key frames in the video content, one or more
representative images, etc., or any combination thereof, as already
discussed. Block 76 may display a thumbnail image based on the
thumbnail information.
[0024] FIG. 6 illustrates an embodiment of a system 700. In

wireless system, a wired system, or a combination of both. When
implemented as a wireless system, system 700 may include components
and interfaces suitable for communicating over a wireless shared
media, such as one or more antennas, transmitters, receivers,
transceivers, amplifiers, filters, control logic, and so forth. An
example of wireless shared media may include portions of a wireless
spectrum, such as the RF spectrum and so forth. When implemented as
a wired system, system 700 may include components and interfaces
suitable for communicating over wired communications media, such as
input/output (I/O) adapters, physical connectors to connect the I/O
adapter with a corresponding wired communications medium, a network
interface card (NIC), disc controller, video controller, audio
controller, and so forth. Examples of wired communications media
may include a wire, cable, metal leads, printed circuit board
(PCB), backplane, switch fabric, semiconductor material,
twisted-pair wire, co-axial cable, fiber optics, and so forth.
[0043] Platform 702 may establish one or more logical or physical
channels to communicate information. The information may include
media information and control information. Media information may
refer to any data representing content meant for a user. Examples
of content may include, for example, data from a voice
conversation, videoconference, streaming video, electronic mail
("email") message, voice mail message, alphanumeric symbols,
graphics, image, video, text and so forth. Data from a voice
conversation may be, for example, speech information, silence
periods, background noise, comfort noise, tones and so forth.
Control information may refer to any data representing commands,
instructions or control words meant for an automated system. For
example, control information may be used to route media information
through a system, or instruct a node to process the media
information in a predetermined manner. The embodiments, however,
are not limited to the elements or in the context shown or
described in FIG. 6.
[0044] As described above, system 700 may be embodied in varying
physical styles or form factors. FIG. 7 illustrates embodiments of
a small form factor device 800 in which system 700 may be embodied.
In embodiments, for example, device 800 may be implemented as a
mobile computing device having wireless capabilities. A mobile
computing device may refer to any device having a processing system
and a mobile power source or supply, such as one or more batteries,
for example.
[0045] As described above, examples of a mobile computing device
may include a personal computer (PC), laptop computer, ultra-laptop
computer, tablet, touch pad, portable computer, handheld computer,
palmtop computer, personal digital assistant (PDA), cellular
telephone, combination cellular telephone/PDA, television, smart
device (e.g., smart phone, smart tablet or smart television),
mobile internet device (MID), messaging device, data communication
device, and so forth.
[0046] Examples of a mobile computing device also may include
computers that are arranged to be worn by a person, such as a wrist
computer, finger computer, ring computer, eyeglass computer,
belt-clip computer, arm-band computer, shoe computers, clothing
computers, and other wearable computers. In embodiments, for
example, a mobile computing device may be implemented as a smart
phone capable of executing computer applications, as well as voice
communications and/or data communications. Although some
embodiments may be described with a mobile computing device
implemented as a smart phone by way of example, it may be
appreciated that other embodiments may be implemented using other
wireless mobile computing devices as well. The embodiments are not
limited in this context.
[0047] As shown in FIG. 7, device 800 may comprise a housing 802, a
display 804, an input/output (I/O) device 806, and an antenna 808.
Device 800 also may comprise navigation features 812. Display 804
may comprise any suitable display unit for displaying information
appropriate for a mobile computing device. I/O device 806 may
comprise any suitable I/O device for entering information into a
mobile computing device. Examples for I/O device 806 may include an
alphanumeric keyboard, a numeric keypad, a touch pad, input keys,
buttons, switches, rocker switches, microphones, speakers, voice
recognition device and software, and so forth. Information also may
be entered into device 800 by way of microphone. Such information
may be digitized by a voice recognition device. The embodiments are
not limited in this context.
[0048] Thus, techniques described herein may enable the generation
of thumbnail images for a wide variety of video content. Moreover,
the same thumbnail images may be created regardless of the OS
decoder being used. In addition, techniques described herein can
reduce power consumption, extend battery life, and reduce display
time.
[0049] Various embodiments may be implemented using hardware
elements, software elements, or a combination of both. Examples of
hardware elements may include processors, microprocessors,
circuits, circuit elements (e.g., transistors, resistors,
capacitors, inductors, and so forth), integrated circuits,
application specific integrated circuits (ASICs), programmable
logic devices (PLDs), digital signal processors (DSPs), field
programmable gate array (FPGA), logic gates, registers,
semiconductor device, chips, microchips, chip sets, and so forth.
Examples of software may include software components, programs,
applications, computer programs, application programs, system
programs, machine programs, operating system software, middleware,
firmware, software modules, routines, subroutines, functions,
methods, procedures, software interfaces, application program
interfaces (API), instruction sets, computing code, computer code,
code segments, computer code segments, words, values, symbols, or
any combination thereof. Determining whether an embodiment is
implemented using hardware elements and/or software elements may
vary in accordance with any number of factors, such as desired
computational rate, power levels, heat tolerances, processing cycle
budget, input data rates, output data rates, memory resources, data
bus speeds and other design or performance constraints.
[0050] One or more aspects of at least one embodiment may be
implemented by representative instructions stored on a
machine-readable medium which represents various logic within the
processor, which when read by a machine causes the machine to
fabricate logic to perform the techniques described herein. Such
representations, known as "IP cores" may be stored on a tangible,
machine readable medium and supplied to various customers or
manufacturing facilities to load into the fabrication machines that
actually make the logic or processor.
[0051] Embodiments of the present invention are applicable for use
with all types of semiconductor integrated circuit ("IC") chips.
Examples of these IC chips include but are not limited to
processors, controllers, chipset components, programmable logic
arrays (PLAs), memory chips, network chips, and the like. In
addition, in some of the drawings, signal conductor lines are
represented with lines. Some may be different, to indicate more
constituent signal paths, have a number label, to indicate a number
of constituent signal paths, and/or have arrows at one or more
ends, to indicate primary information flow direction. This,
however, should not be construed in a limiting manner. Rather, such
added detail may be used in connection with one or more exemplary
embodiments to facilitate easier understanding of a circuit. Any
represented signal lines, whether or not having additional
information, may actually comprise one or more signals that may
travel in multiple directions and may be implemented with any
suitable type of signal scheme, e.g., digital or analog lines
implemented with differential pairs, optical fiber lines, and/or
single-ended lines.
[0052] Example sizes/models/values/ranges may have been given,
although embodiments of the present invention are not limited to
the same. As manufacturing techniques (e.g., photolithography)
mature over time, it is expected that devices of smaller size could
be manufactured. In addition, well known power/ground connections
to IC chips and other components may or may not be shown within the
figures, for simplicity of illustration and discussion, and so as
not to obscure certain aspects of the embodiments of the invention.
Further, arrangements may be shown in block diagram form in order
to avoid obscuring embodiments of the invention, and also in view
of the fact that specifics with respect to implementation of such
block diagram arrangements are highly dependent upon the platform
within which the embodiment is to be implemented, i.e., such
specifics should be well within purview of one skilled in the art.
Where specific details (e.g., circuits) are set forth in order to
describe example embodiments of the invention, it should be
apparent to one skilled in the art that embodiments of the
invention can be practiced without, or with variation of, these
specific details. The description is thus to be regarded as
illustrative instead of limiting.
[0053] Some embodiments may be implemented, for example, using a
machine or tangible computer-readable medium or article which may
store an instruction or a set of instructions that, if executed by
a machine, may cause the machine to perform a method and/or
operations in accordance with the embodiments. Such a machine may
include, for example, any suitable processing platform, computing
platform, computing device, processing device, computing system,
processing system, computer, processor, or the like, and may be
implemented using any suitable combination of hardware and/or
software. The machine-readable medium or article may include, for
example, any suitable type of memory unit, memory device, memory
article, memory medium, storage device, storage article, storage
medium and/or storage unit, for example, memory, removable or
non-removable media, erasable or non-erasable media, writeable or
re-writeable media, digital or analog media, hard disk, floppy
disk. Compact Disk Read Only Memory (CD-ROM), Compact Disk
Recordable (CD-R), Compact Disk Rewriteable (CD-RW), optical disk,
magnetic media, magneto-optical media, removable memory cards or
disks, various types of Digital Versatile Disk (DVD), a tape, a
cassette, or the like. The instructions may include any suitable
type of code, such as source code, compiled code, interpreted code,
executable code, static code, dynamic code, encrypted code, and the
like, implemented using any suitable high-level, low-level,
object-oriented, visual, compiled and/or interpreted programming
language.
[0054] Unless specifically stated otherwise, it may be appreciated
that terms such as "processing," "computing," "calculating,"
"determining," or the like, refer to the action and/or processes of
a computer or computing system, or similar electronic computing
device, that manipulates and/or transforms data represented as
physical quantities (e.g., electronic) within the computing
system's registers and/or memories into other data similarly
represented as physical quantities within the computing system's
memories, registers or other such information storage, transmission
or display devices. The embodiments are not limited in this
context.
[0055] The term "coupled" may be used herein to refer to any type
of relationship, direct or indirect, between the components in
question, and may apply to electrical, mechanical, fluid, optical,
electromagnetic, electromechanical or other connections. In
addition, the terms "first", "second", etc. may be used herein only
to facilitate discussion, and carry no particular temporal or
chronological significance unless otherwise indicated.
[0056] Those skilled in the art will appreciate from the foregoing
description that the broad techniques of the embodiments of the
present invention can be implemented in a variety of forms.
Therefore, while the embodiments of this invention have been
described in connection with particular examples thereof, the true
scope of the embodiments of the invention should not be so limited
since other modifications will become apparent to the skilled
practitioner upon a study of the drawings, specification, and
following claims.
