DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0055] Hereinafter, exemplary embodiments will be described in
greater detail with reference to the accompanying drawings.
[0056] Features described in the following description are provided
to assist in an understanding of exemplary embodiments. Thus, it is
apparent that exemplary embodiments can be carried out without
those specifically defined matters. Functions and or elements known
in the related art are not described in detail since they would
obscure the exemplary embodiments with unnecessary detail and same
reference numerals are used for the same elements when they are
depicted in different drawings.
[0057] FIGS. 1 and 2 illustrate a configuration and an operation of
a display system according to exemplary embodiments. The display
system includes a display apparatus 100 and glasses apparatuses
200-1 and 200-2. Although the display apparatus 100 is realized by
a television in FIGS. 1 and 2, the display apparatus 100 may be
realized by various kinds of apparatuses having a display, such as
a mobile phone, a personal digital assistant (PDA), a laptop or
tablet personal computer (PC), a monitor, an electronic book
(e-book), an electronic album, a kiosk, etc.
[0058] The display apparatus 100 provides a multi-view function.
The multi-view function refers to a function that provides a
plurality of different contents using a single display apparatus
100. If two contents are displayed as shown in FIGS. 1 and 2, such
a multi-view function may be referred to as a dual view function.
Throughout the specification, the term "multi-view function" is
used. If the multi-view function is selected, the display apparatus
100 generates a plurality of content views and displays the content
views in sequence.
[0059] In FIG. 1, a plurality of content views are constituted
using two two-dimensional (2D) contents A and B and are alternately
displayed according to an exemplary embodiment. In FIG. 1, the
content views are illustrated as A and B for convenience of
explanation. The contents A and B may be various types of contents
such as a broadcast program received through a broadcast channel, a
multi-media content provided from a network source, and a
multimedia content stored in a storage element provided internal or
external to the display apparatus 100. Contents A and B may be
moving image contents, still images, text, graphical user
interfaces, etc.
[0060] The glasses apparatuses 200-1 and 200-2 may be realized in a
shutter glasses method. In a shutter glasses method, each of the
left-eye glass and the right-eye glass of a glasses apparatus
contain a shutter (for example, a liquid crystal layer which opens
and closes by controlling the polarization of the liquid crystals)
which is synchronized with a display apparatus so as to allow a
user to view only the images intended. Specifically, the first
glasses apparatus 200-1, which is matched with the content A, opens
both the left-eye shutter and the right-eye shutter when the
content view A is output, and closes both the left-eye shutter and
the right-eye shutter when the content view B is output.
Accordingly, a user who wears the first glasses apparatus 200-1
recognizes only the content view A.
[0061] On the other hand, the second glasses apparatus 200-2, which
is matched with the content B, opens both shutters when the content
B is output. Accordingly, a user who wears the second glasses
apparatus 200-2 recognizes only the content view B.
[0062] The display apparatus 100 transmits a synchronization (sync)
signal so that each of the glasses apparatuses 200-1 and 200-2 can
be synchronized with an output time of each content view. The sync
signal is a signal to synchronize a time at which a content view is
displayed on the display apparatus 100 with a time at which shutter
glasses of a glasses apparatus matched with the corresponding
content view are operated. Depending on an exemplary embodiment,
the sync signal may be realized to inform a time at which one
content view is displayed or include sync information regarding
each of the entire content views.
[0063] The sync signal may be transmitted in various ways. For
example, the sync signal may be transmitted by broadcasting an
infrared ray (IR) signal or a radio frequency (RF) signal, or may
be transmitted according to various wireless communication
protocols such as Bluetooth, Wi-Fi, ZigBee, or IEEE. Hereinafter, a
case where the sync signal is transmitted according to the
Bluetooth method will be explained.
[0064] FIG. 2 is a view illustrating a display apparatus which
performs a multi-view function using two three-dimensional (3D)
contents A and B according to an exemplary embodiment. The 3D
content includes a left-eye image and a right-eye image.
Accordingly, the content A includes a left-eye image content view
AL and a right-eye image content view AR, and the content B
includes a left-eye image content view BL and a right-eye image
content view BR. Accordingly, the content views AL, AR, BL, and BR
are displayed in sequence.
[0065] A first glasses apparatus 200-1 opens a left-eye shutter in
synchronization with an output time of the left-eye image content
view AL of the content A, and opens a right-eye shutter in
synchronization with an output time of the right-eye image content
view AR of the content A. Accordingly, a user who wears the first
glasses apparatus 200-1 can view the 3D content A
three-dimensionally. On the other hand, a second glasses apparatus
200-2 opens a left-eye shutter in synchronization with an output
time of the left-eye image content view BL of the content B and
opens a right-eye shutter in synchronization with an output time of
the right-eye image content view BR of the content B. Accordingly,
a user who wears the second glasses apparatus 200-2 can view the 3D
content B three-dimensionally.
[0066] The display system of FIGS. 1 and 2 may perform a function
of reproducing a single 3D content as well as the multi-view
function. If a single 3D content is reproduced, each glasses
apparatus 200-1 and 2002- alternately opens the left-eye shutter
and the right-eye shutter in synchronization with display times of
the left-eye image and the right-eye image.
[0067] If communication with the glasses apparatus is connected in
such a display system, the display apparatus 100 provides a sync
signal. Each of the glasses apparatuses 200-1 and 200-2 drives each
shutter glass using the sync signal. Each of the glasses apparatus
200-1 and 200-2 is synchronized with an output time of a content
view that the user of the glasses apparatus wishes to view from
among the content views currently displayed on the display
apparatus 100.
[0068] FIG. 3 is a block diagram illustrating a display apparatus
according to an exemplary embodiment. Referring to FIG. 3, the
display apparatus 100 includes a remote control signal receiver
110, a controller 120, a sync signal generator 130, a communicator
140, a video processor 150, and a display 160.
[0069] The remote control signal receiver 100 receives a remote
control signal from a remote controller. The remote control signal
may be transmitted in various communication methods. For example,
the remote control signal may be a code signal which is a
combination of a leader code, a custom code, and a data code, and
may be transmitted using a carrier frequency signal included in a
frequency band defined according to a manufacturer or a
product.
[0070] The controller 120 performs various operations according to
remote control signals received at the remote control signal
receiver 110. For example, if a turn-on command is input, the
controller 120 supplies power to each components in the display
apparatus 100 and turns on the display apparatus 100. Also, if a
channel change command or a volume control command is input, the
controller 120 may perform channel changing or volume controlling.
Although only the remote control signal receiver 110 is
illustrated, the controller 120 may perform various control
operations according to user commands input through buttons or
inputting means provided on the display apparatus 100.
[0071] If a command to execute a multi-view function is input, the
controller 120 controls the video processor 150 to process a
plurality of contents and generate a plurality of content views.
The content recited herein may be a multimedia content which is
provided from various sources as described above. The content view
recited herein refers to a video frame of each content. A content
providing source and a type thereof will be explained below.
[0072] The video processor 150 detects video data from each content
and generates a video frame using the video data. The video
processor 150 places the video frames generated based on different
contents at least one at a time, alternately, thereby forming
output data.
[0073] The display 160 receives the output data which is formed by
the video processor 150 and displays a plurality of content views
alternately.
[0074] The video processor 150 and the display 160 constitute an
outputter 1000 to output contents. The outputter 1000 may further
include elements in addition to the video processor 150 and the
display 160.
[0075] The sync signal generator 130 generates a sync signals
regarding the plurality of content views. The sync signal may be
generated in various formats according to a wireless communication
method applied between the display apparatus 100 and the glasses
apparatus. For example, the sync signal may be generated as an RF
signal or an IR signal or may be generated in the format of a data
packet according to various kinds of wireless communication
standards such as Bluetooth, Wi-Fi, ZigBee, or IEEE.
[0076] As described above, the sync signal may be realized in
various forms and include various information according to
exemplary embodiments.
[0077] For example, the sync signal may be generated for each
content view and transmitted. In this case, a plurality of
frequencies of a carrier signal may be allocated according to the
number of content views, and a clock signal where a rising edge and
a falling edge are formed according to a time at which each content
view is displayed may be modulated to each frequency signal and
output.
[0078] In another exemplary embodiment, the sync signal may be
transmitted in a form that includes all of synchronization
information regarding each of the entire content views. In this
case, a glasses apparatus may receive and store the information,
and use synchronization information corresponding to a specific
content view in order to perform synchronization according to a
user's selection.
[0079] To be specific, the sync signal may include a reference
clock signal and sync information to inform a time at which each
content view is displayed with reference to the reference clock
signal. The sync information may consist of information which
indicates a delay time from a specific point within a reference
clock signal such as a rising edge or a falling edge to a time at
which each content view is displayed.
Alternatively, the sync signal may be divided into a plurality of
sync periods. Each of the sync periods is divided by a rising edge
or a falling edge of a pulse indicating synchronization
information. The sync signal may include state information
indicating whether a multi-view function is currently executed or a
3D content is reproduced in every sync period, and time information
to synchronize an output time of each content view and a driving
time of shutter. The time information may be realized by sync
information directly informing an output time of each content view,
and may include reference time information and delay information
which indicates a delay time from the reference time to the output
time of each content view. In addition, the sync signal may include
diverse information according to exemplary embodiments. For
example, the sync signal may include unique information of the
entire glasses apparatuses paired with the display apparatus
100.
[0080] The communicator 140 transmits the sync signal generated by
the sync signal generator 130 to external glasses apparatuses. The
communicator 140 may communicate with the glasses apparatuses
according to the above-described various kinds of communication
methods.
[0081] If a multi-view function is executed and thus a plurality of
content views are displayed, the controller 120 may select a target
content view which is controllable by a remote controller from
among those content views. The target content view refers to a view
that is authorized to be controlled by the remote controller. The
target view may be changed according to user selection. That is,
the user may select a content view synchronized with his/her own
glasses apparatus as the target content view by manipulating
various keys on the remote controller.
[0082] If a remote control signal is received, the controller 120
processes the target content view from among the plurality of
content views according to the remote control signal. For example,
if the content displayed on the target content view is a broadcast
signal, a channel or a volume may be controlled by selecting a
channel key or a volume key, and, if the content is a multimedia
content file, operations such as content change, rewind, fast
forward, replay, pause, and stop may be controlled.
[0083] If a new glasses apparatus is connected to the communicator
140, the controller 120 controls the communicator 140 to transmit
information on the target content view to the new glasses
apparatus. Accordingly, the new glasses apparatus is controlled to
synchronize with the target content view. Herein, the new glasses
apparatus refers to a glasses apparatus which performs pairing
while communication with a display apparatus is cut off, or a
glasses apparatus which performs a re-connection.
[0084] FIGS. 4 and 5 are views illustrating an operation of
selecting a content view which is assigned remote control
authority, that is, a target content view according to exemplary
embodiments.
[0085] Referring to FIGS. 4 and 5, the display apparatus 100
sequentially displays content views A and B. In order to change one
of the plurality of content views (for example, if content view A
is a broadcast channel and the user wishes to change content view A
to a different broadcast channel), the content view that the user
wishes to change (in this example, convent view A) is first
assigned remote control authority. In other words, one of the
plurality of content views is selected as the target content view.
The user may select a target content view using a specific key
which is assigned a function for changing remote control authority
from among keys provided on a remote controller 300. For example, a
left direction key may be matched with a function to select a first
content view and a right direction key is matched with a function
to select a second content view. If, in this example, a left
direction key signal is input, the controller 120 may select the
first content view A as the target content view, and, if a right
direction key signal is input, the controller 120 may select the
second content view B as the target content view.
[0086] Alternatively, number keys such as a number one key or a
number two key may be matched with a function to change the remote
control authority. Also, a single key may be matched with such a
function. In this example, if a corresponding key is pressed, the
remote controller 200 transmits a remote control signal including a
command to change the control authority to the display apparatus
100. If the control authority change command is received in a state
where the content view A is the target content view, the controller
120 selects the content B as the target content view. That is, the
controller 120 selects the next content view as the target content
view every time the remote control signal including the control
authority change command is received.
[0087] In FIG. 4, the content view A is selected as the target
content view. An on screen display (OSD) message 10 indicating that
the target content view A is controllable by the remote controller
is displayed on the content view A.
[0088] If the remote controller 300 is manipulated in this state,
the content view B is selected as the target content view as shown
in FIG. 5. Accordingly, the OSD message 10 is displayed on the
target content view B.
[0089] The controller 120 may set the target content view using a
control authority setting region which is provided in an internal
memory (not shown) for the purpose of setting the target content
view. For example, in a state where a dual view mode is executed
and thus two content views are displayed, if a first content view
is selected as a target content view, the controller 120 may record
a digital code 00 on the control authority setting region. On the
other hand, if a second content view is selected as the target
content view, the controller 120 may record a digital code 01. If
the control authority change command is input, the controller 120
changes the digital code from 00 to 01 or from 01 to 00. After
that, if various control signals are input, the controller 120
identifies the code recorded on the control authority setting
region and determines a content view to be processed. The
controller 120 controls an element for processing the determined
content view, and processes the content view according to the input
control signals. The detailed operation will be explained in detail
below.
[0090] Although only the OSD message 10 is displayed on the target
content view to inform that the content view is controllable by the
remote controller in FIGS. 4 and 5, any other OSD messages may be
displayed on the content view.
[0091] For example, if communication with a new glasses apparatus
is connected, the controller 120 may display an OSD message
indicating that the new glasses apparatus is connected on the
content view. In this case, the OSD message may be displayed only
on the content view selected as the target content view from among
the plurality of content views. The communication connection may
refer to reconnection after communication is broken down after
initial pairing is achieved, as well as initial pairing of the
glasses apparatus.
[0092] As described above, if communication between the new glasses
apparatus and the display apparatus 100 is connected, the
controller 120 transmits information on the target content view to
the new glasses apparatus so that the new glasses apparatus is
synchronized with the content view selected as the target content
view at that time. Accordingly, the new glasses apparatus is
automatically synchronized with the output time of the target
content view after the communication is connected.
[0093] FIG. 6 is a view illustrating communication connected
between a new glasses apparatus and a display apparatus according
to an exemplary embodiment. Referring to FIG. 6, the display
apparatus 100 displays the two content views A and B alternately.
The display apparatus 100 transmits a sync signal so that each
content view is synchronized with a glasses apparatus.
[0094] In FIG. 6, first and second glasses apparatuses 200-1 and
200-2 are already connected to the display apparatus 100 for
communication. The first glasses apparatus 200-1 is synchronized
with an output time of the first content view A and turns on left
and right shutters, and the second glasses apparatus 200-2 is
synchronized with an output time of the second content view B and
turns on left and right shutters. As described above, the users of
the first and the second glasses apparatuses 200-1 and 200-2 may
have control authority of the remote controller 300 selectively. In
FIG. 6, the second content view B is selected as the target content
view.
[0095] In this state, if third and fourth glasses apparatuses 200-3
and 200-4 are newly paired, the display apparatus 100 transmits
information indicating that the second content view B is
controllable by the remote controller, that is, information on the
target content view, to the third and the fourth glasses
apparatuses 200-3 and 200-4. If the communication is completed, the
third and the fourth glasses apparatus 200-3 and 200-4 are
synchronized with the second content view B directly based on the
sync signal. If the third and the fourth glasses apparatus 200-3
and 200-4 are connected for communication, the display apparatus
100 displays a message 20 indicating the connection state on the
second content view B, which is the target content view.
Accordingly, the users who wear the third and the fourth glasses
apparatuses 200-3 and 200-4 can recognize that their own glasses
apparatuses are normally paired and may control processing of their
content view B using the remote controller 300.
[0096] In the above exemplary embodiments, the display apparatus
100 transmits the information on the target content view to the
glasses apparatus and the glasses apparatus is automatically
synchronized with the target content view. However, according to
another exemplary embodiment, the controller 120 may directly match
the new glasses apparatus with the target content view. In this
embodiment, the controller 120 may transmit a sync signal
corresponding to the output time of the target content view to the
new glasses apparatus, instead of transmitting the information on
the target content view to the new glasses apparatus. That is, if
each glasses apparatus is paired and is matched with one of the
plurality of content views, the controller 120 stores an ID of the
glasses apparatus along with the information on the matched content
view. The controller 120 generates a sync signal according to
information on the output time of the corresponding content view
and transmits the sync signal using the ID of the corresponding
glasses apparatus. In this exemplary embodiment, the sync signal
may be generated differently according each content view and may be
transmitted. The other elements are similar to those of FIG. 3 in
their operations and thus detailed illustrating and explanation are
omitted.
[0097] FIG. 7 is a timing chart to explain an operation between a
display apparatus 100 and a glasses apparatus 200 according to an
exemplary embodiment. FIG. 7 illustrates an operation if the
glasses apparatus 200 is connected when the display apparatus 100
is performing a multi view function.
[0098] Referring to FIG. 7, a user who wears the glasses apparatus
200 may input a pairing command by manipulating a key provided on
the glasses apparatus 200 (S710). If the pairing command is input,
the glasses apparatus 200 transmits a pairing trigger signal to the
display apparatus 100 (S720). The pairing trigger signal may
include diverse information including address information of the
glasses apparatus 200. The pairing trigger signal may be referred
to as an inquiry signal. The pairing trigger signal may be
broadcasted to external apparatuses including the display apparatus
100.
[0099] If the pairing trigger signal is received, the display
apparatus 100 transmits a response signal including address
information to the glasses apparatus 200 (S730). The glasses
apparatus 200 stores the address information included in the
response signal (S740). The glasses apparatus 200 transmits a
response signal using the stored address information (S750). The
response signal may include information for pairing with the
display apparatus. A format of this signal may vary depending on
the communication method. The signal format will be explained in
detail below.
[0100] If the response signal is received, the display apparatus
100 establishes a communication link with the glasses apparatus 200
using the information included in the response signal.
[0101] If the communication link with the glasses apparatus 200 is
established, the display apparatus 100 determines which content
view is controllable by a remote controller from among a plurality
of content views, that is, which one is a target content view
(S760). If the target content view is determined, the display
apparatus 100 transmits information on the target content view to
the glasses apparatus 200 (S770). Also, the display apparatus 100
transmits a sync signal to the glasses apparatus 200 (S780). The
information on the target content view or the sync signal may
include information on a current operational state of the display
apparatus 100. For example, information regarding whether a
currently displayed content is a 3D content or a 2D content or
whether the display apparatus displays a single content or is
operated in a multi-view mode to process a plurality of contents
may be transmitted to the glasses apparatus 200. The glasses
apparatus 200 is directly synchronized with the target content view
using the sync signal and the information on the target content
view, and is driven (S790). That is, if the display apparatus is
operated in the multi-view mode, the glasses apparatus 200
collectively opens and closes the left-eye shutter and the
right-eye shutter according to an output time of the target content
view.
[0102] Although the information on the target content view is
transmitted to the glasses apparatus in a Bluetooth communication
method, only the pairing process may be performed in the Bluetooth
communication method and the information on the target content view
may be provided to the glasses apparatus in an RF communication
method.
[0103] That is, the display apparatus 100 transmits the sync signal
in the Bluetooth communication method, and transmits an audio
signal in the RF communication method. In this case, each of the
display apparatus 100 and the glasses apparatus 200 should include
both a Bluetooth module and an RF communication module. Also, the
RF communication module should be paired separately from the
Bluetooth module. If the Bluetooth pairing is achieved, the display
apparatus 100 transmits a pairing packet using the RF communication
module (not shown). The glasses apparatus perform audio pairing by
transmitting a response signal in response to the pairing packet.
If the audio pairing with the glasses apparatus 200 is achieved,
the display apparatus 100 may transmit the information on the
target content view using the RF communication module.
[0104] In FIG. 7, the glasses apparatus is newly paired. However,
the glasses apparatus may be reconnected after the communication is
broken down. FIG. 8 is a timing chart illustrating an operation of
reconnecting communication according to an exemplary
embodiment.
[0105] Referring to FIG. 8, the display apparatus 100 transmits a
sync signal to the glasses apparatus 200 which is connected to the
display apparatus 100 for communication (S810). The glasses
apparatus 200 is synchronized with one of the plurality of content
views and is driven (S815). The user may select a content view
using a button provided on the glasses apparatus 200. If the button
is selected, the glasses apparatus 200 is synchronized with a next
content view of the currently synchronized content view. As
described in more detail below, if the sync signal transmitted from
the display apparatus 100 includes sync information of each content
view, the glasses apparatus 200 may include means to select one of
the plurality of content views (for example, a switch).
[0106] If a turn-off command is input in this state (S820), the
glasses apparatus 200 stores information on the currently
synchronized content view (S825). In addition, the glasses
apparatus 200 may store diverse information received from the
display apparatus 100. If the information is stored, the glasses
apparatus 200 performs a turn-off operation (S830).
[0107] The turn-off command may be input by manipulating a button
provided on the glasses apparatus 200 or may be transmitted from
the display apparatus 100 when the display apparatus 100 is turned
off. Even if a separate turn-off command is not input from the
user, the glasses apparatus 200 may automatically store the
information and then is turned off if a motion sensor provided in
the glasses apparatus 200 does not sense any motion for more than a
predetermined time or if a touch sensor, which is provided on the
glasses apparatus out of reach of the user's body, does not sense
contact for more than a predetermined time.
[0108] If turn-on is performed in the turn-off state (S835), the
glasses apparatus 200 transmits a signal for requesting
communication reconnection with the display apparatus 100 using the
pre-stored address information of the display apparatus 100 (S840).
The display apparatus 100 transmits information on the target
content view in response to this request signal (S845), and
transmits a sync signal (S850). The glasses apparatus 200 is
synchronized with the target content view based on the information
on the target content view and the sync signal, and is driven
(S855).
[0109] As described above, the glasses apparatus 200 can be
directly synchronized with the content view controllably by the
remote controller if communication is reconnected, as well as if
communication with the display apparatus 100 is initially
connected. The glasses apparatus 200 and the display apparatus 100
may be connected to each other for communication according to
various communication methods. One of them is the Bluetooth
standard. FIG. 9 illustrates an example of a packet format
transmitted during a pairing process according to the Bluetooth
standard according to an exemplary embodiment.
[0110] Referring to FIG. 9, the packet may include information on a
Bluetooth address (3DG BD address), a device type, a version of the
glasses apparatus (3DG version No), a battery type, a remaining
battery voltage, a battery charting status, a remaining battery
ratio, a remaining battery time, and a color shift.
[0111] FIG. 9 illustrates a packet comprised of 17 bytes. If a
transport packet is comprised of 17 bytes, there is a reserved
region of 1 byte and 4 bytes. Additional information may be
recorded on this reserved region.
[0112] In the above exemplary embodiments, the plurality of content
views are displayed using video data of the plurality of contents.
However, the content may be a moving picture or other content.
[0113] FIG. 10 is a block diagram illustrating a display apparatus
which processes a moving image content according to an exemplary
embodiment. Referring to FIG. 10, the display apparatus 100
includes a remote control signal receiver 110, a controller 120, a
sync signal generator 130, a communicator 140, an OSD processor
170, an outputter 1000, a receiver 181, an interface 182, and a
storage 183.
[0114] The outputter 1000 processes a content and outputs the
content. The outputter 1000 includes a de-multiplexer 184, a video
processor 150, a display 160, an audio processor 191, an audio
outputter 192, and an audio signal outputter 193. The outputter
1000 receives a content through the receiver 181, the interface
182, and the storage 183, and processes the content.
[0115] The receiver 181 receives a broadcast program content
through a broadcast network. The receiver 181 may include a tuner
to tune to a broadcast channel, a demodulator to demodulate a
broadcast signal received through the tuned broadcast channel, and
an equalizer to equalize the demodulated broadcast signal. The
receiver 181 may be realized in various forms according to a
broadcast standard adopted by a country where the display apparatus
100 is used. Also, although one receiver 181 is illustrated in FIG.
10, the receiver 181 may be a plurality of receivers. That is, if a
multi-view function is performed using a plurality of broadcast
programs, the controller 120 controls the plurality of receivers
181 to tune to different broadcast channels. The outputter 1000
forms a plurality of content views using the broadcast signals
received through the broadcast channels, and alternately outputs
the content views on a screen.
[0116] The interface 182 receives a content file from a server
apparatus through the Internet or other local networks. In
particular, in order to accesses a web server through the Internet
and receive a content file, the interface 182 may be realized by a
network interface card.
[0117] The storage 183 stores various content files. The storage
183 may store a recording file in which the broadcast signal
received at the receiver 181 is recorded or may store a content
file streamed or downloaded through the interface 182. In addition,
the storage 183 may store an operating system (O/S) or other
programs to drive the display apparatus 100 and various setting
values set by the user for the display apparatus 100. In
particular, the storage 183 may store final information on a
content selected in a single view mode and final information on a
content selected in a multi-view mode. If the display apparatus 100
is turned on after having been turned off or is switched between
the single view mode and the multi-view mode, the controller 120
selects a content using the final information stored in the storage
183. This will be explained in detail below.
[0118] The controller 120 controls an overall operation of the
display apparatus 100 according to user's selection. The display
apparatus 100 may support the multi-view mode and the single view
mode. If the multi-view mode is selected, the controller 120 may
obtain a plurality of contents using the receiver 181, the
interface 182, and the storage 183. Although not shown in FIG. 10,
the display apparatus 100 may further include a reproducing
apparatus have a variety of external recording media mounted
thereon to reproduce data. For example, if a recording medium such
as a CD, a DVD, a blue-ray disk, a memory card, or a USB memory is
mounted, the display apparatus 100 may further include a
reproducing means for reading out data from the recording
medium.
[0119] The de-multiplexer 184 separates audio data and video data
from the content obtained through various elements such as the
receiver 181, the interface 182, and the storage 183. The separated
video data is provided to the video processor 150 and the separated
audio data is provided to the audio processor 191.
[0120] The video processor 150 decodes the video data, scales the
video data according to a screen size, and then converts a frame
rate according to an output rate. If the multi-view mode is
initiated, the video processor 150 generates video frames using
video data of different contents, and connects the video frames to
a top-to-bottom format or a side-by-side format, thereby generating
output video data.
[0121] The display 160 alternately displays the plurality of
content views on the screen using the output video data generated
by the video processor 150. The display 160 may be realized by a
liquid crystal display (LCD) including a display panel (not shown)
and a backlight (not shown). However, the display 160 may be
realized by other displays such as an organic light emitting diode
(OLED) type display or a plasma display panel (PDP) type
display.
[0122] The audio processor 191 performs various processing such as
decoding, noise filtering, and amplification with respect to the
audio data provided by the de-multiplexer 184. The audio processor
191 provides the processed audio data to the audio outputter 192 or
the audio signal outputter 193. The audio outputter 192 outputs an
audio signal (for example. a speaker), and the audio signal
outputter 193 modulates the audio signal and transmits it to an
external apparatus.
[0123] The audio signal outputter 193 includes an RF communication
module. The audio signal outputter 193 performs pairing with the RF
communication module included in the glasses apparatus 200, and
thus transmits diverse information such as target content view
information and volume information as well as the audio signal.
[0124] The controller 120 may be operated in the single view mode
or the multi-view mode as described above. The single view mode or
the multi-view mode may be selected on a menu screen. For example,
if a menu command is input through the remote control signal
receiver 110 or a key provided on a body of the display apparatus
100, the controller 120 displays a menu screen including various
menus executable by the display apparatus 100. If a multi-view menu
is selected on the menu screen, the controller 120 performs the
multi-view mode and thus generates the plurality of content views
as described above.
[0125] If the multi-view mode is selected, the controller 120 may
directly select a plurality of sources using a default value and
may generate a plurality of content views. However, alternatively,
the user may select a number of content views, a source, and a
content. That is, if the multi-view menu is selected, the
controller 120 may display a content selection screen through the
display 160 to select the number of content views, a source of a
content view, and a content name.
[0126] If the user selects the number of content views as two and
selects a source of each content view as a television (TV)
broadcast signal, the controller 120 controls the receiver 181 and
the outputter 1000 to receive two broadcast signals and generate
two content views.
[0127] In this case, the controller 120 may determine a content to
be displayed on each content view using final information stored in
the storage 183. The final information may be source information,
channel information, and/or volume information.
[0128] For example, if a broadcast signal may be selected as a
source of first and second content views broadcast channels 10 and
11 may have been selected as the first and second content views in
a multi-view mode. In this example, if the multi-view mode is
terminated or if the display apparatus 100 is turned off, the
controller 120 stores broadcast channel information of each content
view in the storage 183. Volume information may be stored along
with the broadcast channel information. If the multi-view mode is
initiated again, the controller 120 directly tunes to channel 10
and channel 11 using the stored channel information, and then
controls to generate the first and the second content views using
the broadcast signal received through those channels. The volume
information is also identified so that a volume level of the audio
signal provided along with the first and the second content views
is adjusted to be a final value.
[0129] In another example, a stored content (for example, content
stored in an internal or external memory device) may be selected as
the content of the first content view, and that broadcast channel
20 is selected as the content of the second content view. In this
example, if the multi-view mode is terminated or if the display
apparatus is turned off, the controller 120 stops producing the
corresponding content and stores a storage address, a content name,
and a stop time of the content in the storage 183. After that, if
the multi-view mode is executed again, the controller 120 resumes
the playback of the content from where the user left off, thereby
constituting the first content view, and tunes to broadcast channel
20, thereby constituting the second content view.
[0130] If a web server or storage media are selected as the source
of each content view, the controller 120 controls the outputter
1000 to receive the content through the interface 182 or the
storage 183.
[0131] The above-described menu screens or the content selection
screen may be generated by the OSD processor 170. That is, the OSD
processor 170 generates various OSD messages under control of the
controller 120 and provides the OSD messages to the display 160.
The display 160 renders the OSD message by overlaying it with the
video frame on the screen. Also, the OSD processor 170 may generate
OSD messages of various forms such as a remote control authority, a
pairing state, a channel number, a volume level, or broadcast
information.
[0132] On the one hand, if the display apparatus 100 is operated in
the single view mode, the controller 120 controls the audio
processor 191 and the audio outputter 192 to synchronize the audio
signal with the video frame of the content currently displayed and
output the audio signal. Accordingly, since the audio signal
synchronized with the video frame displayed is output through a
speaker, the user can view a 2D content without wearing a glasses
apparatus.
[0133] On the other hand, if the multi-view mode is initiated, the
controller 120 controls the audio processor 191 to process the
audio data de-multiplexed from the plurality of contents and
generate a plurality of audio signals. The controller 120 may
control the audio signal outputter 193 to output the plurality of
audio signals through different channels. The different channels
may be different radio frequency signal channels. That is, the
audio signal outputter 193 modulates the audio signals into a
carrier wave having different radio frequencies, and transmits the
audio signals. Accordingly, each glasses apparatus tunes to a
frequency channel using frequency information corresponding to a
content view synchronized therewith, demodulate the audio signal
received through the frequency channel, and outputs sound. Also,
the audio signal outputter 193 configures an audio stream according
to a communication format transmittable through the communicator
140 based on the audio signals, and may transmit the audio stream
through the communicator 140. Each of the glasses apparatuses
detects the audio signal corresponding to the currently
synchronized content view from the audio stream, and outputs the
audio signal through a speaker or an earphone attached to the
glasses apparatus.
[0134] If the volume information is not stored, the controller 120
may equally set volume level of the plurality of audio signals as a
default value. For example, a volume level of the audio signal can
be adjusted through each glasses apparatus. If each glasses
apparatus is paired with the display apparatus 100, the audio
signal is amplified (up or down) according to the volume level
which is set as the default value by the controller 120, and is
output. On the other hand, if each glasses apparatus is reconnected
after communication is broken down, the audio signal is amplified
according to a volume level set before the communication is broken
down, and is output. The glasses apparatus will be explained in
detail below.
[0135] In the exemplary embodiment of FIG. 10, the controller 120
may change the target content view by assigning the remote control
authority to content views in sequence according to user's
selection. Also, if the communication with the glasses apparatus is
connected, the display apparatus transmits information on the
target content view to the corresponding glasses apparatus so that
the glasses apparatus can be directly synchronized with the target
content view.
[0136] Because the sync signal generator 130 and the communicator
140 have been described above with reference to FIG. 3, a detailed
explanation is omitted.
[0137] As shown in FIG. 10, the display apparatus 100 may perform
the multi-view function using the contents provided from various
sources such as a broadcasting station, a server, or other storage
media. However, this is merely an example and some of the features
may be modified or omitted. For example, if the display apparatus
100 is realized by a TV without Internet access, the display
apparatus 100 may include only a plurality of receivers and may use
only a broadcast signal received through the plurality of receivers
for the multi-view function.
[0138] In the above-described exemplary embodiments, the controller
120 may be realized in various configurations.
[0139] FIG. 11 is a block diagram illustrating an example of the
controller according to an exemplary embodiment.
[0140] Referring to FIG. 11, the controller 120 includes a read
only memory (ROM) 121, a random access memory (RAM) 122, a central
processing unit (CPU) 123, a graphic processing unit (GPU) 124, and
a bus 125. The ROM 121, the RAM 122, the CPU 123, and the GPU 124
are connected to one another through the bus 125. Although not
shown, other registers or interfaces may be provided in the
controller 120.
[0141] The CPU 123 accesses the storage 183 and performs booting
using an O/S stored in the storage 183. The CPU 123 performs
various operations using various programs, contents, and data
stored in the storage 183.
[0142] The ROM 121 stores a command set for system booting. If a
turn-on command is input and power is supplied, the CPU 123 copies
an O/S stored in the storage 183 to the RAM 122 according to a
command stored in the ROM 121, executes the OS, and boots the
system. If the booting is completed, the CPU 123 copies various
application programs stored in the storage 183 to the RAM 122,
executes the application programs copied to the RAM 122, and
performs various operations. If a remote control signal to select a
multi-view function is input, the CPU 123 loads a program for
executing the multi-view function into the RAM 122 and executes the
program. If a remote control signal is received, the CPU 123
selects a target content view which is set to have remote control
authority using a corresponding program, and outputs a control
command to process the target content view in response to a remote
control signal to the outputter 1000.
[0143] If communication with a new glasses apparatus is connected,
the CPU 123 transmits information on the target content view to the
new glasses apparatus. In addition, the GPU 124 generates various
graphic objects and displays them on a screen. The configuration of
the controller 120 illustrated in FIG. 11 is merely an example and
the controller 120 may be realized in other configurations.
[0144] FIG. 12 is a flowchart illustrating a multi-view display
method of a display apparatus according to an exemplary embodiment.
Referring to FIG. 12, the multi-view display method processes a
plurality of contents, thereby generating a plurality of video
frames, and alternately displays the video frames, thereby
providing a plurality of content views (S1210). The plurality of
contents may be selected based on final information of a previous
multi-view mode.
[0145] The display apparatus 100 transmits a sync signal on each
content view (S1220). In this state, if communication with a new
glasses apparatus is connected (S1230), the display apparatus
identifies a target content view which is currently controllable by
a remote controller (S1240). If the target content view is
identified, the display apparatus transmits information on the
target content view to the glasses apparatus (S1250). Such
information may be transmitted separately from the sync signal.
However, according to an exemplary embodiment, the information may
be inserted into a part of the sync signal and may be transmitted
along with the sync signal. A format or size of the information on
the target content view may be set to an optimal value considering
various factors such as a number of supportable content views or an
entire size of the sync signal. For example, the glasses apparatus
may be notified which content view is the target content view using
a two-digit number digital code.
[0146] After the communication is connected, the new glasses
apparatus is directly synchronized with the target content view
according to the information on the target content view.
Accordingly, a user who wears the new glasses apparatus can control
a processing operation of his/her own content view using the remote
controller.
[0147] FIG. 13 is a block diagram illustrating a glasses apparatus
according to an exemplary embodiment. Referring to FIG. 13, a
glasses apparatus 200 includes first and second shutter glasses 210
and 220, a shutter glasses driver 230, a controller 240, and a
communicator 250.
[0148] Each of the first and the second shutter glasses 210 and 220
includes a plurality of transparent electrodes, a liquid crystal
layer disposed between the transparent electrodes, a polarization
plate, and a transparent substrate to support the aforementioned
elements. Accordingly, liquid crystals of the liquid crystal layer
are opened or closed according to a voltage applied to the
plurality of transparent electrodes. Penetration of light is
blocked in a closed state, and light penetrates in an open state
like glass.
[0149] The shutter glasses driver 230 includes a driving circuit
which is connected to the transparent electrodes provided in the
first and the second shutter glasses 210 and 220. The shutter
glasses driver 230 drives the first and the second shutter glasses
210 and 220 separately by applying a driving signal to the
transparent electrodes provided in the first and the second shutter
glasses 210 and 220. The shutter glasses driver 230 alternately
opens and closes the first and the second shutter glasses 210 and
220 when a 3D content is reproduced. If a multi-view function is
executed, the shutter glasses driver 230 turns on or turns off the
first and the second shutter glasses 210 and 220 collectively.
[0150] If communication connection with a display apparatus 100 is
initiated, the communicator 250 receives various signals from the
display apparatus 100. Specifically, the communicator 250 may
receive information on a target content view which is controllable
by a remote controller from among a plurality of content views, and
a sync signal.
[0151] The controller 240 controls an overall operation of the
glasses apparatus 200. Specifically, if the information on the
target content view is received from the display apparatus 100, the
controller 240 controls the shutter glasses driver 230 to drive the
first and the second shutter glasses 210 and 220 in synchronization
with the target content view.
[0152] If communication is connected between the glasses apparatus
200 and the display apparatus 100, the information on the target
content view may be transmitted from the display apparatus 100.
Accordingly, if communication is connected, the glasses apparatus
200 can be directly synchronized with the content view which is
controllable by the remote controller and displays various
messages.
[0153] If a multi-view function is executed to display a plurality
of contents as described above, each glasses apparatus may
separately provide audio data of a synchronized content.
[0154] FIG. 14 is a block diagram illustrating a glasses apparatus
which provides audio data according to an exemplary embodiment.
Referring to FIG. 14, a glasses apparatus 200 includes a first
shutter glass 210, a second shutter glass 220, a shutter glasses
driver 230, a controller 240, a communicator 250, an audio signal
receiver 261, an audio signal processor 262, an audio outputter
263, an input receiver 270, and a storage 280.
[0155] Because operations of the first and the second shutter
glasses 210 and 220 and the shutter glasses driver 230 have been
described with reference to FIG. 13, a detailed explanation is
omitted.
[0156] The input receiver 270 includes various kinds of keys in
order to a user to control an operation of the glasses apparatus
200. Specifically, a power key, a pairing key, a content view
change key, and a volume control key may be provided on the input
receiver 270. These keys may be realized in various forms such as a
push button, a dial, a jog shuttle, a wheel, and a touch pad.
[0157] The controller 240 may perform various control operations
according to a manipulation state of the various kinds of keys
provided on the input receiver 270. For example, if the power key
is selected while the glasses apparatus is powered off, the
controller 240 resumes the supply of power to each element from a
battery (not shown) and performs a turn-on operation, and, if the
power key is selected while the glasses apparatus is powered on,
the controller 240 cuts off the power supply using a switch (not
shown).
[0158] If the pairing key to perform pairing with a display
apparatus is selected, the controller 240 controls the communicator
250 to perform pairing. Specifically, the controller 240 controls
the communicator 250 to transmit a pairing trigger signal to the
display apparatus. If address information of the display apparatus
is received through the communicator 250, the controller 240 stores
the address information in the storage 280. The communicator 250
performs communication connection with the display apparatus using
the stored address information. The communicator 250 may use the
address information obtained during the pairing process when
performing communication reconnection. That is, if the power of the
display apparatus which has been once turned off is turned on while
the glasses apparatus 200 is connected to the display apparatus 100
for communication and is used, the controller 240 controls the
communicator 250 to perform communication reconnection with the
display apparatus using the address information stored in the
storage 280.
[0159] The storage 280 may store various data such as a sync signal
and information on a target content view received through the
communicator 250, in addition to the address information received
from the display apparatus. Also, the storage 280 may store various
kinds of driving programs for driving the glasses apparatus.
[0160] The audio signal receiver 261 receives an audio signal that
corresponds to a content view synchronized with the glasses
apparatus from among a plurality of audio signals output from the
display apparatus. As described above, if a multi-view function is
performed, the display apparatus 100 detects audio data from each
content and output the audio data through a different radio
frequency channel. The audio signal receiver 261 tunes a radio
frequency channel and receives an audio signal using radio
frequency channel information corresponding to a content view
selected by the controller 240. The radio frequency channel
information may be included in the information on the target
content view or the sync signal transmitted from the display
apparatus 100, and may be transmitted along with the information on
the target content view or the sync signal. Alternatively, the
radio frequency channel information may be transmitted to the
glasses apparatus 200 in a separate signal format.
[0161] The audio signal processor 262 processes the audio signal
received by the audio signal receiver 261, and detects audio data.
Specifically, the audio signal processor 262 may perform processing
such as demodulation, noise filtering, and amplification.
[0162] The audio outputter 263 outputs the audio data processed by
the audio signal processor 262. The audio outputter 263 may be
realized by a speaker or an earphone. The audio outputter 263 may
output the audio data at a volume level which is pre-set for the
audio data. The volume level may be controlled using a variable
resistance provided at an output end. That is, if a volume control
key provided on the input receiver 270 is manipulated, the audio
outputter 263 changes the volume level of the output audio signal
(for example, the volume level may be changed by changing the value
of a variable resistor according to the manipulation of the volume
control key).
[0163] If a volume control command is input through the input
receiver 270, the controller 240 controls the audio outputter 263
to control a volume of the audio data according to the volume
control command. In this state, if a turn-off command to turn off
the glasses apparatus is input through the input receiver 270, the
controller 240 stores finally controlled volume information in the
storage 280 before performing the turn-off operation.
[0164] After that, if a turn-on command to turn on the glasses
apparatus is input through the input receiver 270, the controller
240 controls the communicator 250 to reconnect communication with
the display apparatus 100. Also, the controller 240 controls the
audio outputter 263 to control an output volume of the audio data
based on the volume information stored in the storage 280. As a
result, when communication reconnection is performed, the glasses
apparatus 200 is synchronized with a target content view which
displays an OSD message and is controllable by a remote controller,
and outputs the audio signal at a volume level which is previously
set.
[0165] On the other hand, if pairing with the display apparatus is
achieved, the controller 240 may control the audio outputter 263 to
control an initial volume of the audio data according to a volume
level which is set as a default value in the display apparatus.
[0166] FIG. 15 is a view illustrating an example of an exterior of
the glasses apparatus 200 according to an exemplary embodiment. As
shown in FIG. 15, the glasses apparatus 200 includes a glasses
frame to support a plurality of shutter glasses 210 and 220, and a
plurality of audio outputter 263-1 and 263-2 which are disposed on
the glasses frame to be placed in proximity with user's ears.
[0167] Although the first and the second shutter glasses 210 and
220 are of a rectangular shape in FIG. 15, the first and the second
shutter glasses 210 and 220 may have other shapes such as a circle
or oval shape. Although the audio outputter 263-1 and 263-2 are
realized in the form of a speaker in FIG. 15, the audio outputter
263-1 and 263-2 may be realized in the form of an earphone.
[0168] FIG. 16 is a flowchart illustrating a method for driving a
glasses apparatus according to an exemplary embodiment. Referring
to FIG. 16, if communication connection with a display apparatus is
established (S1610), the glasses apparatus receives information on
a target content view (S1620). The communication connection may
include communication reconnection besides pairing. The information
on the target content view refers to information indicating a
content view assigned remote control authority. Because the method
for selecting a target content view has been described in the
above-described exemplary embodiments in detail, a detailed
explanation is omitted.
[0169] If the information on the target content view is received,
the glasses apparatus is synchronized with the target content view
based on the information on the target content view (S1630). That
is, the glasses apparatus collectively opens left-eye and right-eye
shutter glasses at a time when the target content view is output,
and collectively closes the left-eye and the right-eye shutter
glasses at a time when a different content view is output.
Accordingly, a user who wears the glasses apparatus 200 can control
the initial content view that the user sees using a remote
controller. That is, the user may tune to a broadcast channel,
display an OSD menu, and set a function displayed on the OSD
menu.
[0170] If the contents displayed on the display apparatus is moving
picture contents including audio data, the glasses apparatus should
process an audio signal transmitted from the display apparatus.
[0171] FIG. 17 is a flowchart illustrating a method for driving a
glasses apparatus which processes an audio signal according to an
exemplary embodiment. Referring to FIG. 17, if pairing with a
display apparatus is achieved (S1710), the glasses apparatus
receives a target content view (S1720) and drives each shutter
glass in synchronization with the target content view (S1730). The
glasses apparatus outputs an audio signal at the same time of
driving the shutter glasses. An output volume level of the audio
signal is controlled based on a default value which is set in the
display apparatus or the final output volume level which was set
and stored in a previous multi-view mode (S1740).
[0172] If communication reconnection rather than pairing is
established (S1750), the glasses apparatus is directly synchronized
with the display apparatus using information on the target content
view (S1760 and S1770), and controls the output volume using the
volume level information previously controlled (S1780). That is,
even if the user turns on the glasses apparatus again after having
turned off the glasses apparatus, the user can listen to the audio
signal at a previous volume level without having to control the
volume separately.
[0173] As described above, according to the various exemplary
embodiments, if the glasses apparatus is newly connected to the
display apparatus in the state where the multi-view function to
provide a plurality of content views is executed, the user can
directly view the target content view which is assigned remote
control authority from among the plurality of content views.
Accordingly, the user who wears the new glasses apparatus may
select a desired content or may select other various processing
operations using the remote controller. As a result, user's
convenience is improved.
[0174] The display apparatus 100 may operate in the above-mentioned
multi-view mode by converting an operation mode in accordance with
a user manipulation. For example, if a user manipulates a remote
controller or a button provided on a body of the display apparatus
100, the display apparatus 100 displays a UI screen including
various menus. The user may select a menu on the UI screen to
convert an operation mode to a multi-view mode and select various
options necessary to execute the multi-view mode so as to use the
multi-view mode.
[0175] FIGS. 18 and 19 are views illustrating examples of a screen
configuration of the display apparatus 100 according to various
examples.
[0176] According to FIG. 18, if a user selects a menu button while
the display apparatus 100 operates in a TV reception mode, and a TV
broadcast channel screen 1800 (for example, channel 10) is being
displayed, Graphic User Interface (GUI) menus 1810, 1820, 1830 are
displayed on the screen 1800. The menus may include various menus
such as a menu 1810 to connect to the Internet, a menu 1820 to
operate in a multi-view mode, and a menu 1830 to operate in a 3D
mode and so on. If the display apparatus 100 is realized in a
configuration like the configuration illustrated in FIG. 10, the
OSD processor 170 may display the menus 1810, 1820, 1830. The OSD
processor 170 may be configured to include an operation unit (not
shown), a rendering unit (not shown), and a buffering unit (not
shown). The operation unit operates property values such as
coordinates value, shape, size, and color which are to be displayed
on each subject according to a layout of the corresponding screen
based on layout data of the screen stored in the storage unit 183.
The rendering unit generates menus 1810, 1820, 1830 based on the
property values operated by the operation unit as illustrated in
FIG. 18. The menu data generated by the rendering unit is stored in
the buffering unit. The menu data stored in the buffering unit is
displayed by the display unit 160.
[0177] A user may select one of the menus by touching the screen of
the display apparatus 100 or manipulating a direction key and
confirmation key provided on the body of the display apparatus.
[0178] If the multi-view mode 1820 is selected, the display
apparatus 100 displays the UI 1830 to set the number of content
views to be provided in the multi-view mode. For example, if it is
possible to provide 2, 3, or 4 content views, as illustrated in
FIG. 18, a menu 1831 to select a dual-view, a menu 1832 to select a
triple-view, and a menu 1833 to select a quadruple-view may be
displayed in the UI 1830.
[0179] If a user selects the menu 1831 to select a dual-view,
preview screens 1840, 1850 for two content views may be displayed.
The controller 120 may configure the preview screens 1840, 1850
using viewing history information stored in the storage unit 183.
Specifically, the controller 120 may store information regarding
contents provided by each content view or an input source of the
contents in the storage unit 183 whenever a multi-view mode is
terminated. Further, the controller 120 may also store information
regarding applicable options when the corresponding content with
respect to each content view is reproduced, such as volume, color,
brightness, contrast, whether to display subtitles, language, and
so on. If the multi-view mode is executed again later, the
controller 120 controls the outputter 1000 to process a video
signal and an audio signal using such information stored in the
storage unit 183.
[0180] For example, as illustrated in FIG. 18, a screen which has
been displayed at that time (that is, broadcast channel 10) is
maintained on one screen 1840 from among preview screens and a
screen provided from the same input source as the final input
source selected in the previous multi-view mode is displayed on the
other screen 1850. In FIG. 18, a broadcast signal screen received
through the previous broadcast channel 30 is set to the second
content view 1850 automatically.
[0181] A user may change a content matched with each content view
or an input source while watching the preview screens 1840, 1850.
The controller 120 may control the OSD processor 170 to display a
guide image informing that a channel can be changed or menus 1841,
1851 to change channels on the lower part of the preview screens
1840, 1850. A user may change channels of each content view by
touching the menus 1841, 1851 directly or using buttons of a remote
controller.
[0182] If selection of a content matched with each content view or
an input source is completed, a user may terminate the setting of
multi-view mode operation by selecting a confirmation button on the
body of the display apparatus 100. If the confirmation button is
selected, the controller 120 controls the outputter 1000 to
generate a plurality of content views in accordance with a setting
value set through each UI. FIG. 18 illustrates a state in which the
screen of broadcast channel 10 and a screen of broadcast channel 30
are provided through content views 1 and 2 (1800-1, 1800-2),
respectively.
[0183] In FIG. 18, the multi-view mode using a TV input source has
been explained, but the above-mentioned input source may be set not
only as a TV but also as a recording medium reproduction apparatus
such as a DVD and a Blue-ray reproduction apparatus. Accordingly, a
menu to select an input source may also be included in a UI to set
multi-view mode operation.
[0184] FIG. 19 illustrates an example of UI configuration including
such menus. According to FIG. 19, if a menu button is selected
while the display apparatus 100 displays a broadcast channel screen
1900, a UI 1910 including various available menus is displayed.
Each menu may be configured and displayed in the form of icons or
texts. If a user selects a multi-view mode menu 1911 in the UI
1910, the display apparatus 100 displays UIs 1920, 1930 through
which an input source and a content can be selected with respect to
each of a plurality of available content views.
[0185] In FIG. 19, it is assumed that the display apparatus 100 may
support only two content views and the two UIs 1920, 1930 are
displayed. However, even in the case where the display apparatus
100 may support more than two content views, a UI to select the
number of content views is displayed first to receive a user
selection as illustrated in FIG. 18.
[0186] In each UI 1920, 1930, source selection taps 1921, 1931 and
a content selection tap 1922 in the corresponding source are
displayed. In the case of DVD, only a source selection tap 1931 may
be activated and displayed on the UI 1930 since further procedures
such as selecting channels are not necessary, but in the case of TV
or other external input sources for which content selection is
necessary, the content selection tap 1922 may be activated and
displayed.
[0187] In FIG. 19, a TV is selected as a source in the UI 1920
regarding the content view 1, and if broadcast channel 10 is
selected from among the TV sources, a DVD is selected as a source
in the UI 1930 regarding content view 2. Accordingly, an image of
broadcast channel 10 is displayed on the first content view 1900-1
and a DVD play screen is displayed on the second content view
1900-2.
[0188] Meanwhile, the type of content and source which was selected
in the previous multi-view mode may be displayed first on each UI
1920, 1930. A user may use the displayed type of source and content
as they are, or may change the setting.
[0189] As described above, a display apparatus provides information
so that a glasses apparatus may be matched with a content view
having remote control authority when it is paired or communication
is resumed after being cut off. FIG. 20 is a timing view provided
to explain the process of connecting a display apparatus with a
glasses apparatus and the process of providing information in
detail.
[0190] According to FIG. 20, the display apparatus 100 includes
CPU, BT_TX, and Audio TX. CPU, BT_TX, and Audio TX are
corresponding to the controller 120, the communicator 140, and the
audio signal outputter 193 in the above exemplary embodiments,
respectively. In addition, the glasses apparatus 200 includes BT_RX
and Audio Rx. BT_RX and Audio Rx are corresponding to the
communicator 250 and the audio signal receiver 261 in the glasses
apparatus 200, respectively.
[0191] According to FIG. 20, if a user presses a pairing button in
a glasses apparatus, a pairing is initiated. Accordingly, BT_RX 250
transmits an inquiry to BT_TX 140. The BT_RX 250 and the BT_TX 140
performs predetermined processes (such as, baseband ack)
sequentially according to standard.
[0192] Meanwhile, the BT_RX 250 transmits a pairing start signal
(GPIO) to Audio Rx 261. The Audio Rx 261 is activated by the
signal.
[0193] On the other hand, the BT_TX 140 notifies the CPU 120 of EIR
Handshake event (HCI). The CPU 120 selects whether to user 3D audio
glasses according to the notification. To be specific, a UI may be
displayed to inquiry about whether to use 3D audio glasses in order
to receive a user selection.
[0194] If it is determined that glasses are to be used, the CPU 120
transmits signals for starting pairing and remote control to the
Audio Tx 193. If the corresponding signal is received, the Audio Tx
193 broadcasts a packet A for pairing. Alternatively, if it is
determined that the glasses are not to be used, the Audio Tx 193
broadcasts a packet B to stop pairing.
[0195] If the packet A is not received within a predetermined time
period or the packet B is received, the Audio Rx 261 notifies the
BT-Rx 250 that pairing is not succeeded. On the other hand, if the
packet A is received, the Audio Rx 261 transmits acknowledgement to
the Audio Tx 193.
[0196] If the acknowledgement is received, the Audio Tx 193
transmits information regarding content views for which remote
control is available, that is, information regarding target content
views to the Audio Rx 261 and subsequently, the Audio Rx 261 sends
acknowledgement. If the acknowledgement is received, the Audio Tx
193 transmits a pairing completion signal to the CPU 120.
[0197] After receiving the acknowledgement, the Audio Rx 261
transmits a pairing completion signal including information
regarding target content views to the BT-Rx 250. The BT-Rx 250
provides information regarding target content views to the
controller 240, and the controller 240 controls the shutter driver
230 to synchronize with the target content views immediately.
Through these processes, pairing and initial synchronization may be
performed.
[0198] FIG. 20 illustrates that the communicator 250 and the audio
signal receiver 261 performs all of the above-described operations
in the glasses apparatus 200, but the controller 240 may involve in
some of the operations.
[0199] FIG. 21 illustrate an example of configuration of a display
screen which can be watched through a glasses apparatus when
pairing is completed in the same way as FIG. 20.
[0200] FIG. 21 illustrates a case in which a first content view
2110 and a second content view 2120 are being provided and the
second content view 2120 is a target content view. In this case,
the first content view 2110 may be regarded as a main screen, and
the second content view 2120 may be regarded as a sub screen.
[0201] In this state, if the glasses apparatus 200 is newly paired,
the glasses apparatus 200 is directly synchronized with the second
content view 2120 which has remote control authority. If the new
glasses apparatus 200 is connected through pairing, OSDs 2111, 2121
indicating a screen type may be displayed on each content view
2110, 2120. In addition, an OSD 2122 indicating that the second
content view 2120 has remote control authority may be displayed on
the second content view 2120, a target content view for which
remote control is available. Accordingly, a user wearing the
glasses apparatus 200 may immediately aware that an
initially-displayed screen is a sub screen and remote control is
available.
[0202] Meanwhile, the above exemplary embodiments have explained a
case in which, if a glasses apparatus is initially paired or
reconnected after its communication is cut off, the glasses
apparatus is immediately synchronized with a content view with
remote control authority, regardless of a user's intention, but in
another exemplary embodiment, a user may select a screen.
[0203] FIG. 22 is a view provided to explain a display apparatus
and an operation of a glasses apparatus according to another
exemplary embodiment.
[0204] According to FIG. 22, the first glasses apparatus 200-1 is
matched with the first content view 2210 and the second glasses
apparatus 200-2 is matched with the second content view 2220 while
the first and second content views 2210, 2220 are displayed
alternately. In addition, the second content view 2220 is selected
as a content view which is controllable by the remote controller
300, that is, a target content view. In this state, if a new
glasses apparatus, that is the third glasses apparatus 200-3 is
connected, the third glasses apparatus 200-3 is immediately matched
with the second content view 2220.
[0205] In this case, an OSD message 2211 representing that a main
channel is displayed on the first content view 2210, and an OSD
message 2221 representing a sub channel and an OSD message 2222 for
selecting a main channel or a sub channel are displayed on the
second content view 2220. A user may select a main channel or a sub
channel with reference to the OSD message 2222.
[0206] FIG. 22 illustrates a case where the OSD message 2222 is
displayed only one screen 2220 having remote control authority,
but, otherwise, the OSD message 2222 may be displayed both on the
first and second content views 2210, 2220. In addition, regardless
of remote control authority, the OSD message 2222 may be displayed
on only one content view which is set as default.
[0207] As described above, a display apparatus may provide a
plurality of contents in various ways.
[0208] The multi-view display method of the display apparatus or
the methods for driving the glasses apparatus according to the
above-described various exemplary embodiments may be generated as
software executed by a hardware processor and may be mounted in a
non-transitory computer readable storage medium in the display
apparatus and/or the glasses apparatus.
[0209] Specifically, according to an exemplary embodiment, a
non-transitory computer readable medium, which stores a program for
performing: alternately displaying a plurality of content views,
transmitting a sync signal regarding the plurality of contents
views to at least one glasses apparatus, identifying a target
content view that is controllable by a remote controller from among
the plurality of content views if communication connection between
a new glasses apparatus and the display apparatus is established,
and transmitting information on the target content view to the new
glasses apparatus so that the new glasses apparatus is synchronized
with the target content view, may be installed in the display
apparatus.
[0210] Also, a non-transitory computer readable medium, which
stores a program for performing: connecting communication with a
display apparatus which alternately displays a plurality of content
views, receiving information on a target content view which is
controllable by a remote controller from among the plurality of
content views, and driving first and second shutter glasses in
synchronization with the target content view, may be installed in
the glasses apparatus.
[0211] The non-transitory computer readable medium may refer to a
medium that stores data temporarily, semi-permanently, or
permanently (for example, a register, a cache, a memory, etc.) and
is readable by an apparatus. Specifically, the above-described
various applications or programs may be stored in a non-transitory
computer readable medium such as a compact disk (CD), a digital
video disk (DVD), a hard disk, a Blueray disk, a universal serial
bus (USB), a memory card, a read-only memory (ROM), etc.
[0212] The foregoing exemplary embodiments and advantages are
merely exemplary and are not to be construed as limiting the
present disclosure. The exemplary embodiments can be readily
applied to other types of apparatuses. Also, the description of the
exemplary embodiments is intended to be illustrative, and not to
