  The present invention relates to a broadcast receiving apparatus that receives a program including a viewpoint-switchable video that is a video whose viewpoint can be switched, and a control method thereof.

  In recent years, in the current BS (Broadcasting Satellite) digital broadcasting, by using a further higher transmission band, higher resolution of video and higher functionality of broadcasting have been studied.

  As an example of enhancement of broadcasting functions, a signal obtained by multiplexing a plurality of video signals photographed by a plurality of imaging devices is received, and a predetermined video signal is selected from the plurality of video signals and displayed on a display device. There is a variable viewpoint television system for display (Patent Document 1).

In addition, when the existing program and the program including the viewable video that can change the viewpoint are distributed in cooperation, the viewpoint of the existing program is set as the initial value when the viewpoint is switched. The technique is disclosed in Patent Document 2.
Japanese Patent Laid-Open No. 5-130528 JP 2007-150747 A

  However, when a program including a view-switchable video as described above is actually broadcast, it is expected that a time zone in which the viewpoint can be switched and a time zone in which the viewpoint can be switched are mixed. For example, in a program including a viewpoint-switchable video, a video such as CM (Commercial Message) is expected to be a video that cannot be switched.

  Therefore, the present invention provides an easy-to-use broadcast receiving apparatus and a control method thereof that can appropriately perform viewpoint switching when a time zone in which viewpoints can be switched and a time zone in which viewpoints cannot be mixed exist. Objective.

  According to the present invention, it is possible to provide an easy-to-use broadcast receiving apparatus and a control method therefor that can appropriately perform viewpoint switching when a time zone in which viewpoints can be switched and a time zone in which viewpoints can not be mixed. it can.

  The broadcast receiving apparatus according to the present embodiment is a broadcast receiving apparatus that receives a program including a viewpoint-switchable video that is a video whose viewpoint can be switched. A program whose viewpoint can be switched means a program in the following viewing mode. One is a program form in which videos taken by a plurality of TV cameras are simultaneously distributed from a broadcasting station, and a viewer can select and view videos shot by any TV camera by remote control operation. Another form is a program form in which a viewer can cut out and view a video with a desired angle of view from a video shot with a single TV camera by a remote control operation. At this time, switching of the viewpoint corresponds to switching of the angle of view of the displayed video.

  When a program including a viewpoint-switchable video is actually broadcast, it is expected that a time zone in which the viewpoint can be switched and a time zone in which the viewpoint can be switched are mixed. In such a case, in the broadcast receiving apparatus, if it is necessary to switch the viewpoint for each time zone in which the viewpoint can be switched, the usability is extremely deteriorated.

  Specifically, if the output of viewable video in a program whose viewpoint has been switched is temporarily interrupted and then restarted, the viewer will still be able to view the video from the same viewpoint as the previous viewpoint after the restart. It is expected to watch. Therefore, when the viewpoint returns to the initial position, the viewpoint must be switched every time. Such an operation is not desirable because it is troublesome for the viewer.

  Therefore, in the broadcast receiving apparatus according to the present embodiment, it is possible to appropriately switch the viewpoint when the time zone in which the viewpoint can be switched and the time zone in which the viewpoint can be switched are mixed. Specifically, when the viewer switches the viewpoint for the program including the video whose viewpoint can be switched, information representing the viewpoint after the switching is stored. Then, when the output of the viewable video in the program whose viewpoint is switched is temporarily interrupted and then resumed, the viewpoint of the viewable video is switched to the stored viewpoint of the program. Thereby, an easy-to-use broadcast receiving apparatus can be provided.

  Hereinafter, specific examples of the broadcast receiving apparatus according to the present embodiment will be described.

<Example 1>
In the first embodiment, a case will be described in which the temporary interruption of the output of the viewpoint switchable video is caused by outputting a video (normal video) whose viewpoint cannot be switched. The video whose viewpoint cannot be switched is a video of a predetermined scene in a program, a video of CM, or the like. Hereinafter, the broadcast receiving apparatus of the present embodiment will be described in detail.

FIG. 1 is a block diagram illustrating a schematic configuration of the broadcast receiving apparatus 101 according to the first embodiment. As shown in FIG. 1, the broadcast receiving apparatus 101 includes a broadcast reception processing unit 102, a DEMUX (demultiplexer) processing unit 103, a video selection processing unit 104, an audio processing unit 105, a presentation processing unit 106, and the like. The broadcast receiving apparatus 101 includes a remote control receiving unit 107, a control unit 108, a memory unit 109, an internal bus 110, a video output terminal 111, an audio output terminal 112, and the like.

  A broadcast signal (program) broadcast by radio waves and a network is input to the broadcast reception processing unit 102. The broadcast reception processing unit 102 performs demodulation processing and error correction processing on the signal of the designated channel in the input broadcast signal, and generates a TS (transport stream) signal (the structure of the TS signal is described later). To explain in detail). The generated TS signal is output to the DEMUX processing unit 103. In this embodiment, it is assumed that a signal in which a video signal, an audio signal, and additional data (data broadcasting data, program information, etc.) are multiplexed is broadcast as a broadcast signal.

  The DEMUX processing unit 103 separates the TS signal output from the broadcast reception processing unit 102 into a video signal, an audio signal, and additional data (data broadcasting data, program information, etc.). The DEMUX processing unit 103 outputs the video signal to the video selection processing unit 104, outputs the audio signal to the audio processing unit 105, and outputs additional data to the internal bus 110.

  The video selection processing unit 104 decodes (decodes) the video signal output from the DEMUX processing unit 103 and outputs the decoded video signal to the presentation processing unit 106. In addition, when a viewpoint switchable video is input, the video selection processing unit 104 selects and decodes the video signal of the viewpoint selected by the viewer, and outputs the video signal to the presentation processing unit 106.

  The presentation processing unit 106 uses the various data received via the internal bus 110 to generate a presentation screen such as a menu screen. Then, the presentation processing unit 106 outputs the presentation screen generated according to the viewer's instruction, the video signal from the video selection processing unit 104, or a synthesized video thereof to the video output terminal. The video output terminal 111 is connected to a display device (display). As the display device, for example, a display having an electron-emitting device, a liquid crystal display, a plasma display, an organic EL display, or the like may be applied.

  The audio processing unit 105 decodes the audio signal output from the DEMUX processing unit 103 and outputs the decoded audio signal to the audio output terminal 112. The audio output terminal 112 is connected to an audio output device (such as a speaker).

  The remote control receiving unit 107 receives a signal (remote control signal; key code data) from the remote control and transfers it to the control unit 108.

  The control unit 108 analyzes the remote control signal received by the remote control receiving unit 107, and performs a process corresponding thereto. Further, the control unit 108 comprehensively controls each function in the broadcast receiving apparatus 101 via the internal bus 110. For example, when the remote control signal from the remote control receiving unit 107 relates to channel selection, the control unit 108 instructs the broadcast reception processing unit 102 to select (switch) the channel. When the remote control signal from the remote control receiving unit 107 is related to the switching of the viewpoint when viewing the wide-angle video, the control unit 108 instructs the video selection processing unit 104 to switch the video signal to be output. When the remote control signal from the remote control receiving unit 107 is related to audio switching or the like, the control unit 108 instructs the audio processing unit 105 to switch the audio signal to be output. In addition, the control unit 108 instructs the presentation processing unit 106 to generate a synthesized video, or instructs the voice processing unit 105 to generate synthesized speech.

Further, the control unit 108 has a clock function that can measure and manage date, day of the week, time, and the like. When the remote control signal from the remote control receiving unit 107 relates to the display of time and the like, the control unit 108 generates an image such as a time as a presentation image for the presentation processing unit 106 and outputs the presentation image. Instruct. Note that the control unit 108 may instruct the presentation processing unit 106 to synthesize the presentation image with the video signal and output it.

  The memory unit 109 stores character (font) data and image data (icons, etc.) used on the menu screen or the like in advance. In addition, the memory unit 109 stores information indicating the viewpoint after switching when the viewer switches the viewpoint with respect to the program including the viewpoint switchable video. Further, additional data (program information and the like) output from the DEMUX processing unit 103 and various setting data set by remote control operations are stored (accumulated).

  The internal bus 110 is a bus for connecting each function in the broadcast receiving apparatus. The internal bus 110 is used for transferring various signals and data, for example.

  Hereinafter, an example of the configuration of the TS signal output from the broadcast reception processing unit 102 will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a configuration of a TS signal output from the broadcast reception processing unit 102. The TS signal conforms to, for example, IEC (International Electro-technical Commission). Note that the TS signal may conform to the provisions of IEEE (Institute of Electrical and Electronic Engineers). You may follow the rule | regulation of ARIB (Association of Radio Industries and Businesses). Moreover, you may follow other prescriptions.

  As shown in FIG. 2, the TS signal is obtained by time-division multiplexing a plurality of TS packets. Specifically, a video signal (video in the figure), an audio signal (audio in the figure), and additional data (data in the figure) are each transmitted in units of TS packets.

A management information table is configured by combining a plurality of additional data in units of TS packets. The management information table is a PAT (Program Association).
Table) and PMT (Program Map Table). Further, the management information table includes EIT (Event Information Table), NIT (Network Information Table), and the like.

  The EIT describes a table ID, service ID, event ID, program broadcast start time, broadcast time, and the like. In addition to these, some descriptors are described. The DEMUX processing unit 103 (or the control unit 108) determines what program is to be broadcast mainly using the information of the EIT. Specifically, it is determined whether or not the broadcast program includes a video whose viewpoint can be switched. A table such as EIT and program information obtained from the table are stored (accumulated) from the DEMUX processing unit 103 into the memory unit 109 via the internal bus 110.

  Hereinafter, an example of the above-described descriptor will be described. Examples of the descriptor include a component descriptor, a component group descriptor, and a series descriptor shown in FIG.

  In the component descriptor, information on video resolution and aspect ratio is described. The component group descriptor describes whether the broadcast program is a multi-view broadcast program in which a plurality of video signals are grouped. In the series descriptor, for example, when the program is a series such as a series drama, information on the number of times (the first episode, the second episode, etc.) is described. Note that the above-described multi-view broadcast program is a program including a main broadcast and a sub-broadcast, and is different from a program including a video whose view can be switched.

  Hereinafter, an example of a viewpoint selection method in the viewpoint switchable video will be described with reference to FIGS.

  As a method for selecting a viewpoint in a video that can be switched from a viewpoint, as shown in FIG. 3, a plurality of video signals having different viewpoints are transmitted from a broadcasting station, and a desired video signal is selected from these video signals and displayed. There is a way to display. Specifically, as shown in FIG. 3, a plurality of videos 1 to 16 respectively corresponding to a plurality of video signals are displayed, and a video of a desired viewpoint is selected from these videos (the selected video is, for example, , Indicated by a bold line). As shown in FIG. 4, a high-resolution video (video 41) is broadcast from the broadcast station, and a part of the video is selected as an area (display area) to be displayed on the display device, and the selected position (display area). There is a method of switching the viewpoint by moving.

  In the case of the method shown in FIG. 3, an identifier indicating that the video is a viewpoint switchable video may be described as component_group_type information in the component group descriptor shown in FIG. 2. As a result, it can be determined whether or not the program includes a view-switchable video as shown in FIG.

  The component_group_type information is a descriptor indicating whether or not a plurality of videos and audios are a group, and component_group_type = 000 is described in the case of multi-view broadcasting. Therefore, this can be dealt with by assigning an unused identification number such as component_group_type = 001 to the viewable video.

  In the case of the method shown in FIG. 4, it is determined whether or not the program includes a view-changeable video from the video signal format (video resolution) described as component_type information in the component descriptor shown in FIG. Just judge.

  The component_type information is a descriptor representing the resolution of an image (video). When the video resolution is a predetermined resolution (for example, 7680 × 4360) or more, the program displays a video whose viewpoint can be switched as shown in FIG. What is necessary is just to judge that it is a program including.

  The broadcast receiving apparatus according to the present embodiment has a function (message output function) for outputting a message indicating that a viewpoint switching operation cannot be performed when a video whose viewpoint cannot be switched is output. Hereinafter, a specific example of the function will be described with reference to FIGS.

  The flow of processing when the viewer selects a viewpoint will be described below. FIG. 5 is a flowchart showing a process flow when the viewer selects a viewpoint.

  First, when the viewer uses a remote controller or the like to request a viewpoint switching (selection) (viewpoint switching request), the request is transmitted to the control unit 108 via the remote control receiving unit 107. Then, the control unit 108 determines whether or not the currently displayed image is a viewpoint switchable image (step S501). If the video being displayed is a video whose viewpoint can be switched (step S501: Yes), the process proceeds to step S502 to perform a process of switching the angle of view (viewpoint). If the video being displayed is not a video whose viewpoint can be switched (step S501: NO), the process proceeds to step S505.

  In step S502, the control unit 108 determines (calculates) the position of the viewpoint after switching according to the currently displayed image and the content of the instruction from the viewer.

For example, in the broadcasting system shown in FIG. 3, when video 6 is selected, the position of the viewpoint (video after switching) is changed to “upper: video 2” and “lower: video” in accordance with up / down / left / right instructions. 10
“Left: Video 5” “Right: Video 7”.

  Also, in the broadcasting system shown in FIG. 4, when the resolution of the video being broadcast is 7680 × 4360 and the display area is 1920 × 1080, the position of the display area is “upper: 108 dots” in response to the upper instruction. The upper display area may be used. In response to the lower, left, and right instructions, the positions of the display areas are “lower: 108 dots lower display area” “left: 108 dots left display area”, “right: 108 dots right display area” do it. Note that the amount of movement of the display area according to the instruction may be limited so that the display area after movement does not include the outside of the broadcast video.

  Next (in step S502), the control unit 108 notifies the video selection processing unit 104 of the position of the viewpoint determined in step S502. Then, the video selection processing unit 104 selects a video corresponding to the position after the switching, and the video is displayed on the display device (step S503).

  And the control part 108 memorize | stores the information showing the viewpoint selected by the viewer in the memory part 109 (memory | storage means) (step S504). Specifically, the control unit 108 stores the viewpoint position determined in step S502 in the memory unit 109 together with the program ID (an identifier representing the program), and ends the process.

  In step S505, the control unit 108 determines whether or not the currently displayed video (video whose viewpoint cannot be switched) is temporary in the program including the video whose viewpoint can be switched. Specifically, when it is determined in step S501 that the currently displayed video is not a viewpoint switchable video, the cause is that a video such as a CM that cannot switch the viewpoint is temporarily output. Judge whether it is a thing. If the currently displayed video is a video in a program including a video whose viewpoint can be switched (step S505: Yes), the process proceeds to step S506. If the currently displayed video is not a video in a program including a video whose viewpoint can be switched (step S505: No), the processing is terminated without performing any processing in response to a viewer's viewpoint switching request. For example, if it is determined from the above-mentioned EIT information that the program being broadcast is a program that includes a view-switchable video, the currently displayed video is temporarily stored in the program that includes the view-switchable video. What is necessary is just to judge that it is a thing.

  In step S506, the control unit 108 displays a message such as “the viewpoint output is temporarily interrupted and the viewpoint cannot be switched” in response to the viewpoint switching request from the viewer. An instruction is given to the presentation processing unit 106. Then, a message is created by the presentation processing unit 106 and displayed on the display device.

  Next, a description will be given of the flow of processing when the displayed video is switched from a video whose viewpoint can be switched to a video whose normal viewpoint cannot be switched (normal video). FIG. 6 is a flowchart showing the flow of processing when switching from the viewable video to the normal video.

  First, when the video selection processing unit 104 detects the switching from the viewpoint-switchable video to the normal video, the video selection processing unit 104 notifies the control unit 108 of the information (the switch from the arbitrary viewpoint-capable video to the normal video). Then, the control unit 108 determines whether or not the switching is temporary (due to CM or the like) in the program (step S601). That is, it is determined whether or not the output of the viewable video is temporarily interrupted. For example, when the viewpoint-switchable video is switched to the normal video, when the program being broadcast is determined to be a program including the viewpoint-switchable video when the video is switched from the viewpoint-switchable video to the normal video, the switching is performed. It may be determined that the replacement is temporary.

When the switching is temporary in the program (step S601: Yes), the process proceeds to step S602. When the above switching is not temporary in the program (step S601: No), that is, when the program itself is switched (from the program including the viewpoint switchable video to the program not including the viewpoint switchable video) ), The process proceeds to step S604.

  In step S602, the control unit 108 determines whether or not the viewer has performed a viewpoint switching operation at the time of the video switching. If the viewer has performed a viewpoint switching operation (step S602: Yes), the process proceeds to step S603. When the viewer has not performed the viewpoint switching operation (step S602: No), the process proceeds to step S604.

  If the video is switched from the video whose viewpoint can be switched to the normal video while the viewer is performing the viewpoint switching operation, the viewpoint switching operation cannot be performed, so that the viewer may be confused. Therefore, in step S603, the control unit 108 instructs the presentation processing unit 106 to display a message such as “the viewpoint cannot be switched because the output of the video whose viewpoint can be switched is temporarily interrupted”. To do. Then, a message is created by the presentation processing unit 106 and displayed on the display device. After the process of step S603, the process of step S604 is performed.

  In step S604, the control unit 108 instructs the video selection processing unit 104 to switch the display from the viewpoint switchable video to the normal video. Then, the normal image is displayed on the display device.

  Next, the flow of processing when the displayed video is switched from the normal video to the viewable video will be described. FIG. 7 is a flowchart showing the flow of processing when switching from a normal video to a video whose viewpoint can be switched.

  First, when the video selection processing unit 104 detects the switching from the normal video to the viewpoint switchable video, the video selection processing unit 104 notifies the control unit 108 of the information (that the normal video has been switched to the viewpoint switchable video). Then, the control unit 108 determines whether or not the viewpoint has been switched in the currently received program (step S701). For example, in a program including viewpoint-switchable video, if a CM that is a normal video is included in the program, the viewpoint of the viewpoint-switchable video that has been output before the CM is output after the CM is output is determined by the viewer. It is determined whether the viewpoint is switched. If the viewpoint has been switched (step S701: YES), the process proceeds to step S702. If the viewpoint has not been switched (step S701: No), the processing at the time of switching from the normal view angle video to the wide view angle video ends.

  Whether or not the viewpoint has been switched in the currently received program is determined by referring to the program ID and viewpoint position information stored in the memory unit 109. For example, the determination is made based on whether or not the program ID of the program being received (displayed) is stored.

  In step S702, the control unit 108 instructs the video selection processing unit 104 to switch the viewpoint to the viewpoint previously selected in the currently received program. For example, the video selection processing unit 104 is instructed to display the video whose viewpoint can be switched after the CM from the viewpoint selected before the CM. Specifically, the control unit 108 instructs the video selection processing unit 104 to switch the viewpoint to the viewpoint of the program stored in the memory unit 109. Then, the video of that viewpoint is displayed on the display device.

As described above, according to the broadcast receiving apparatus of the first embodiment, when the viewer switches the viewpoint with respect to the program including the viewpoint switchable video, the information indicating the viewpoint after the switching is stored. . Then, when the output of the viewable video in the program whose viewpoint is switched is temporarily interrupted and then resumed, the viewpoint of the viewable video is switched to the stored viewpoint of the program ( Automatically switch to that viewpoint). Specifically, even if the output of the viewable video in the program whose viewpoint is switched is temporarily interrupted by outputting a video such as a CM that cannot change the viewpoint, it is stored. The viewpoint-switchable video is resumed from the viewpoint of the program. Accordingly, it is possible to reduce the trouble of switching the viewpoint each time the viewpoint switchable video is temporarily interrupted.

  In addition, according to the legal transmission / reception apparatus of the present embodiment, when a video whose viewpoint cannot be switched is output, a message indicating that the viewpoint switching operation cannot be performed is output. Thereby, the viewer can easily determine whether or not the current viewpoint can be switched.

  Specifically, when the viewpoint cannot be switched, it is determined whether or not the currently displayed video is a video in a program including a video whose viewpoint can be switched. When the currently displayed video is a video in a program including a video whose viewpoint can be switched, a message that the viewpoint cannot be temporarily switched is displayed. As a result, the viewer can recognize that it cannot be switched, and that it is temporary, so that the viewpoint cannot be switched in a program including a video whose view can be switched. Can be prevented.

  Further, when the video is switched from the video whose viewpoint can be switched to the normal video while the viewer is performing the viewpoint switching operation, it is displayed that the viewpoint cannot be temporarily switched. As a result, it is possible to reduce a sense of incongruity caused by sudden change of viewpoint.

<Example 2>
In the second embodiment, a case will be described in which the output of the video whose viewpoint can be switched is temporarily interrupted by channel selection or turning on / off the power of the broadcast receiving apparatus.

  Since the configuration of the broadcast receiving apparatus according to the second embodiment of the present invention is the same as that of the first embodiment, the description thereof is omitted. Further, the processing procedure for the viewpoint selection processing request from the viewer is the same as in the first embodiment, and thus the description thereof is omitted.

  Hereinafter, the flow of processing when a viewpoint-switchable video is output by turning on a channel or turning on a power source will be described. FIG. 8 is a flowchart showing the flow of processing when a viewpoint-switchable video is output by selecting a channel or turning on a power source.

  First, when a viewpoint-switchable video is output by selecting a channel or turning on the power (that is, the video is displayed on the display device), the control unit 108 previously displays the video including the viewpoint-switchable video. It is determined whether or not the viewpoint has been changed (step S801). If the viewpoint has been switched (step S801: Yes), the process proceeds to step S802. If the viewpoint has not been switched (step S801: No), the process ends.

  Whether or not the viewpoint has been switched before is determined by referring to the program ID and the position information of the viewpoint stored in the memory unit 109. For example, the determination is made based on whether or not the program ID of the program being received (displayed) is stored.

In step S802, the control unit 108 instructs the presentation processing unit 106 to display a confirmation message such as “Do you want to switch to the previously selected viewpoint?”. Then, a message is created by the presentation processing unit 106 and displayed on the display device. That is, when the output of the viewable video is resumed, the control unit 108 determines whether to switch the viewpoint of the viewable video to the viewpoint of the program including the video stored in the memory 109. To select. The viewer confirms the displayed message and selects whether to change the viewpoint.

  Next, in response to an instruction from the viewer, the control unit 108 determines whether the instruction is for switching the viewpoint (step S803). When the instruction from the viewer is for switching the viewpoint (step S803: Yes), the process proceeds to step 804. When the instruction from the viewer is for not switching the viewpoint (step S803: No), the process proceeds to step 805.

  In step S804, the video selection processing unit 104 is instructed to switch the viewpoint to the viewpoint previously selected in the currently received program. Then, the video of that viewpoint is displayed on the display device.

  In step S805, the control unit 108 discards information from the memory unit 109 such as the position of the viewpoint previously selected in the program being received.

  As described above, according to the broadcast receiving apparatus of the second embodiment, the viewpoint switchable video in the program whose viewpoint is switched is temporarily output by channel selection or turning off / on the power of the broadcast receiving apparatus. Even if it is interrupted, the viewpoint-switchable video is resumed from the stored viewpoint of the program. Accordingly, it is possible to reduce the trouble of switching the viewpoint each time the viewpoint switchable video is temporarily interrupted.

  As described above, it is possible to provide an easy-to-use broadcast receiving apparatus and a control method thereof that can appropriately perform viewpoint switching when a time zone in which viewpoints can be switched and a time zone in which viewpoints cannot be mixed exist. it can.
