Description

  The present invention relates to an arbitrary viewpoint broadcast (wide-angle broadcast) receiving apparatus capable of reproducing a part of a video and a control method thereof, and relates to a technique for displaying a banner, a menu, and the like simultaneously with the video.

In recent years, with regard to videos such as broadcasts and optical discs, high definition has been advanced from about 720 * 480 pixels of the SD standard to 1920 * 1080 pixels. Furthermore, 7680 * 4320 pixel video is scheduled for the advanced satellite digital broadcasting standard for next-generation broadcasting. Therefore, there is a demand for a function that can enlarge and display an image area (hereinafter referred to as a partial area) that forms a part of the entire area of the high-definition image (hereinafter referred to as the entire area). For example, there has been proposed a playback apparatus that displays an image that is important to a producer or sometimes a user in accordance with an operation instruction of the user.
Consideration must be given so that a user can enjoy a video of a large subject even with a playback device having a relatively small display area such as a portable terminal device. In view of this, a method has been studied in which a partial area that is considered to be particularly important by the producer is multiplexed with meta-information as video and the partial area is reproduced by a user operation. On the other hand, when the display information for operation is displayed in the display area of the display device, the latter display signal is used so that the display information for operation and the video corresponding to the display signal for the received information do not overlap. There is known a technique for reducing an image in accordance with the above (see Patent Document 1).

Japanese Patent Laying-Open No. 2005-151378

When displaying a menu, a banner, or the like on the display screen, the method of simply superimposing these on a part of the video being reproduced has a problem that the video of the overlapped part may not be visible. Further, as in Patent Document 1, when the video being reproduced is reduced so as not to overlap, there remains a problem that a portion where nothing can be displayed occurs in a part of the display area.
Accordingly, an object of the present invention is to provide an apparatus and a control method for changing a video area so that menus, banners, and the like do not overlap the video in a broadcast receiving apparatus having a function of reproducing and displaying a part of the entire video.

  In order to solve the above problems, the present invention is a broadcast receiving apparatus that displays on a display means a first video to be displayed and a second video synthesized with the first video, The area changing means for changing the area including the first video, and when displaying the second video together with the first video, the second video does not overlap the first video, Control means for instructing the area changing means to change the area including the first video is provided.

  According to the present invention, even when the second video is combined with the first video and displayed, the area of the video is set so that the second video does not overlap the displayed video. By changing, it is possible to prevent the user from missing important video.

It is the flowchart figure which illustrated the flow of control in order to demonstrate the broadcast receiver which concerns on 2nd Embodiment of this invention in conjunction with FIG.8 and FIG.9. (A) shows a video example of the entire area, (b) shows a video example of a partial area having no video area, and (c) shows a composite example of a video and a banner. It is the figure which showed the example of an image | video of the partial area | region which does not lack | delete the image | video in (a), and showed the example of a synthetic | combination of an image | video and a banner.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a broadcast receiving apparatus according to the first embodiment. As an example of high-definition input video, viewing of an advanced satellite digital broadcast program received from an antenna will be described. In the following description, an area represented by pixels of the entire video of the received broadcast program is defined as an entire area. Furthermore, a partial area that the producer considers particularly important for a broadcast program has a recommended angle of view (hereinafter referred to as a recommended angle of view) and is multiplexed into metadata. For the recommended view angle, the designated area may change according to the temporal transition. The angle of view of the area that the user considers important is the user angle of view. The user angle of view can be arbitrarily instructed to the apparatus by using operation means such as a remote controller (hereinafter referred to as a remote controller).

The antenna 101 receives a plurality of digital television broadcast signals in which video data, audio data, metadata, and the like are multiplexed and digitally modulated, and sends the received signals to the information acquisition unit 102. The information acquisition unit 102 selects an arbitrary broadcast program from the digital television broadcast signal according to an instruction from the control unit 108 according to a channel selection command from the user, for example. Then, the information acquisition unit 102 performs demodulation, error correction processing, and the like, and outputs an MPEG2-TS (Transport Stream) signal to the signal separation unit 103.
The signal separation unit 103 separates video data and metadata from the multiplexed MPEG2-TS signal in accordance with the broadcast program packet ID selected by the user, and sends the video data to the video reproduction unit 104. Is sent to the metadata processing unit 105. The multiplexed MPEG2-TS signal may include audio data and data broadcast (multimedia) data, but the processing unit is not shown in FIG.

The video playback unit 104 decodes the encoded video data, and sends the processed signal to the region change unit 106. Examples of encoding include ITU-T Rec. H.264 / ISO / IEC14496-10 MPEG-4 Part10 Advanced Video Coding.
The metadata processing unit 105 serving as an information acquisition unit extracts information for filtering the MPEG2-TS signal by the signal separation unit 103 and further information on the entire area and partial area of the video based on a predetermined descriptor. To do. Such information can be extracted from, for example, the EIT described in the PSI / SI table defined by STD-B10 of ARIB, or the component type of the component descriptor in PMT. ARIB is an abbreviation for “Association of Radio Industries and Businesses”. PSI / SI is an abbreviation for “Program Specific Information / Specific Information”. EIT is an abbreviation for “Event Information Table” and PMT is an abbreviation for “Program Map Table”.

  Here, the video information separated by the signal separation unit 103 and the information on the entire area and the partial area will be described in detail. First, an example structure of a component descriptor is shown below.

component_descriptor () {
descriptor_tag
descriptor_length
reserved_future_use
stream_content
component_type
component_tag
ISO_639_language_code
for (i = 0; i <N; I ++) {
text_char
}
}

  In “component_type” indicating the component type, resolution information of the entire area is defined in an 8-bit field. For example, information on the entire area of each program is described such as 480i when the value of the component type is 0x01 and 1080i when the value of the component type is 0xB1. FIG. 2 illustrates an information table defined by “component_type”. For example, in the case of 0xF3, a normal program having a resolution of 4320p and an aspect ratio of 16: 9 is defined. In the case of 0xF2, a broadcast program having a resolution of 4320p and an aspect ratio of 16: 9 and further having partial area information (hereinafter referred to as partial area information) is defined. The control unit 108 can determine whether the target broadcast program is a program having partial area information by receiving descriptor information from the metadata processing unit 105.

  Furthermore, a method for defining and reproducing partial area information with a component descriptor will be described. In the case of a broadcast program having the partial area information, the information can be defined by “text_char” of the component descriptor. For example, it is assumed that the start coordinates of the initial display area are x and y, the display area size is w and h, each is defined by 2 bytes (Byte), and these are described continuously.

  FIG. 3A shows an example of an image of the entire area, and FIG. 3B shows an example of an image of a partial area that is a part of the image of FIG. The X axis in FIG. 3A is set in the horizontal direction of the screen, and the Y axis is set in the vertical direction of the screen. The entire area of this example is x = 1, y = 1, w = 7680, h = 4320. The partial area is x = 1921, y = 1081, w = 3840, h = 2160, and the aspect ratio is 16: 9. By substituting x = 0x0781, y = 0x0439, w = 0x0F00, and h = 0x0870 obtained by converting these decimal values into hexadecimal numbers, it is possible to define the partial area by setting “text_char = 078104390F000870”. Therefore, the broadcast receiving apparatus can reproduce the partial area having the start coordinate and the area size specified by acquiring the value of “text_char”.

  Returning to FIG. 1, the area changing unit 106 changes the area of the video sent from the video reproduction unit 104 in response to an instruction for changing the area from the control unit 108. Further, the area changing unit 106 changes the display resolution on the display unit 107. As an example, a case where a partial area is displayed on a display unit having a resolution of 1920 * 1080 pixels in HD (High Definition Television) will be described. The control unit 108 performs resolution conversion from w = 3840, h = 2160 to w = 1920, h = 1080 shown in FIG.

  The drawing unit 109 obtains the resolution information of the display unit 107, creates a banner according to the banner display instruction from the control unit 108, and sends the display signal to the synthesis unit 110. Further, the drawing unit 109 erases the banner from the display screen in accordance with the banner erase instruction from the control unit 108. An example of the banner is shown in FIG. The program content display banner of the reproduced video has area information of x = 1, y = 721, w = 1920, and h = 360 according to the resolution of the display unit 107.

  The synthesizing unit 110 synthesizes the video and the banner sent from the area changing unit 106 and the drawing unit 109, and sends a composite video signal to the display unit 107. FIG. 4B shows a composite image obtained by superimposing the image obtained by converting the resolution of the image shown in FIG. 3B and the banner shown in FIG. That is, this is an example in which a part of the video (in this example, the UFO video) is hidden by the banner. Therefore, the apparatus according to the present embodiment performs control so that the video to be displayed can be displayed without hindering the banner. Details thereof will be described later.

  The reproduction area storage unit 111 stores information on the reproduction area before the banner display according to an instruction from the control unit 108. For example, if the partial area shown in FIG. 3B is reproduced before the banner display, when the banner display instruction is given, the reproduction area storage unit 111 reads x = 1921, y = 1081, w = 3840, h = Each information of 2160 is stored.

  Next, the operation of the control unit 108 will be described in detail with reference to the flowchart of FIG. Regarding the processing in steps S801 to 816, the control unit 108 starts control when the broadcast receiving apparatus is activated, and ends control when the operation of the broadcast receiving apparatus ends.

  After the start in step S801, in step S802, the control unit 108 determines whether there is a banner display instruction from the user using a remote controller (not shown). As a result, if the control unit 108 determines that there is a banner display instruction, the control unit 108 instructs the metadata processing unit 105 to extract the program information being reproduced, and the process proceeds to S803. If it is determined that there is no banner display instruction, the determination process of S802 is repeated.

  In step S <b> 803, the control unit 108 extracts, from the metadata processing unit 105, video content information, whole area information, and partial area information necessary for the drawing unit 109. The partial area obtained here corresponds to the recommended angle of view. Further, the control unit 108 obtains, from the drawing unit 109, banner area information to be displayed when the banner display is instructed. The displayed video content information is, for example, information related to a program included in the EIT, but will not be described in detail here.

  Next, the banner display processing S804 to 807 will be described. In step S804, the control unit 108 determines whether the area instructed to the area changing unit 106 is the entire area. If it is determined that the target area is not the entire area, the process proceeds to S805. If it is determined that the target area is the entire area, the process proceeds to S807.

  In step S <b> 805, the control unit 108 causes the reproduction area storage unit 111 to store information on the current display angle of view instructed to the area change unit 106. In next step S806, the control unit 108 derives an area of the video where the reproduced video area and the banner do not overlap, and instructs the area changing unit 106 of the derived area. For example, with reference to FIG. 3B, FIG. 4, FIG. 6A, and FIG. 6B, processing is performed as follows.

  The control unit 108 displays the area information instructed to the area changing unit 106 in order to display the image of FIG. 6B instead of the image of FIG. 4B on the display unit 107, as shown in FIG. An instruction is given to change the information indicating the area to the information indicating the area shown in FIG. In FIG. 6A, the area surrounded by a dotted line indicates the area before the change, that is, the area corresponding to FIG. 3B, and the area shown in the entire frame indicates the area after the change.

  Next, a method for deriving the changed area shown in FIG. First, when a banner is displayed on the display unit 107, a process for deriving an area where an image can be displayed without overlapping the banner is performed. For example, the display area of the display unit 107 is a rectangular area (hereinafter referred to as area (1)) surrounded by coordinates (1,1) and coordinates (1920,1080). Then, the banner area information obtained from the drawing unit 109 is a rectangular area surrounded by coordinates (1,721) and coordinates (1920,1080) as shown in the area of FIG. In this case, an area in which an image can be displayed without overlapping the banner is obtained as an area surrounded by coordinates (1,1) and coordinates (1920,720) (hereinafter referred to as area (2)).

  And the process which calculates | requires the resolution conversion rate for displaying the image | video of the area | region (1) displayed before the banner display on an area | region (2) is performed. Here, the horizontal width of the region (1) is defined as w1, the vertical width is defined as h1, the horizontal width of the region (2) is defined as w2, and the vertical width is defined as h2. When displaying the image of area (1) in area (2) while maintaining the aspect ratio, the resolution of area (1) should be further changed according to the smaller of w2 / w1 or h2 / h1 I understand. Hereinafter, this change rate is denoted as R.

  By the way, since the surrounding video (in this example, the video of the house) is not displayed only by changing the resolution, it is necessary for the control unit 108 to derive an area for instructing the area changing unit 106 to change. In order to display the surrounding image, it is necessary to display the image over the entire region (1). Therefore, by multiplying the image area displayed before the banner display by 1 / R, an area where the surrounding image can be displayed is derived. In this example, the information indicating the area of the display image before the banner display, which has been instructed to the area changing unit 106, is the coordinates of the lower left corner (1921, 1081) and the coordinates of the upper right corner as shown in FIG. (5760,3240). W2 / w1 = 1920/1920 = 1 and h2 / h1 = 720/1080 = 2/3 are obtained from the information of area (1) and area (2), and R = 2 / Since 3 is obtained, the changed area can be derived according to this value. The two arrows shown in FIG. 6 (a) indicate a change in the angle of view, and an area having coordinates (1921, 1081) and coordinates (5760, 3240) so that the area within the dotted frame does not overlap the banner area. Change the angle of view to 1 / R times. As a result, a region having coordinates (961,1081) and coordinates (6720,4320) is derived (aspect ratio 16: 9). Then, the area information and the value of the change rate R are instructed to the area changing unit 106.

  In S807 of FIG. 5, the control unit 108 instructs the drawing unit 109 to display a banner. As a result, as shown in FIG. 6B after the resolution conversion, the area displayed with the banner, that is, the rectangular area having the coordinates (1, 1) of the lower left corner and the coordinates (1920, 720) of the upper right corner. An image including an important part is displayed. If it is determined in S804 that the entire area is being reproduced, the control unit 108 controls the display area so that the banner is superimposed on the video as it is.

  Next, banner display end processing S808 and S809 will be described. In step S808, the control unit 108 determines whether an instruction to end banner display by a user operation or system processing has been performed. As a result, if it is determined that an instruction to end banner display has been issued, the process proceeds to S809. If not, the process proceeds to S810.

  In step S809, the control unit 108 ends the banner display process by the drawing unit 109, reads the region information from the reproduction region storage unit 111, and instructs the region change unit 106 of the read region information. That is, when the angle of view before the banner display is the recommended angle of view, the display on the display unit 107 returns to the current recommended angle of view after the banner display ends. Then, the process proceeds to S816 and the process ends.

  Next, in S810 to 815, a process when the recommended view angle is changed or the user view angle is changed before the banner is not displayed will be described. In step S <b> 810, the control unit 108 determines whether an instruction to change the displayed area (display angle of view) has been given regarding an operation instruction from the user using a remote controller (not shown). As a result, when the control unit 108 determines that there is no instruction to change the display area from the user, the process proceeds to S811. If the control unit 108 determines that there is an instruction to change the display area from the user, the process advances to step S812.

  In step S811, the control unit 108 further determines whether or not the current display angle of view is a user angle of view. As a result, when it is determined that the display angle of view is the user angle of view, it is determined that there is no change in the video area. Judgment will continue to be made.

  If it is determined in S810 that the area has been changed by the user's instruction, the process proceeds to S812, where the control unit 108 stores the information on the user's angle of view in the reproduction area storage unit 111 and causes the area change unit 106 to store the user image. Give instructions to change to corners. Thereafter, the process returns to S808.

  If it is determined in S811 that display is not being performed at the user angle of view, the process proceeds to S813. Here, the control unit 108 obtains the latest recommended view angle information from the metadata processing unit 105. In step S814, the control unit 108 causes the reproduction area storage unit 111 to store the updated recommended field angle information instead of the previous area. In the next step S815, as in the processing in step S806, the control unit 108 changes the reference of the video that does not overlap the banner to the updated recommended angle of view, and derives a video area that is instructed to be changed. The derived area is processed so as to be inside the entire area (inside the boundary), and an instruction to change the derived area is issued to the area changing unit 106. Thereafter, the process returns to S808.

  In this embodiment, an advanced satellite digital broadcast program has been described as an example of video content having a partial area. The application of the present invention is not limited to this, and the recommended angle of view can be determined using the above-mentioned metadata even for terrestrial digital broadcasts, CATV broadcasts, broadcasts using IP communication, and stored contents stored in Blu-ray discs. Available. In addition, the partial area information obtained using the above-described metadata is used as an example of the recommended angle of view. However, the same processing as described above can be performed using a partial area of the entire video specified by the user. .

  Further, in the present embodiment, as an example of a method for deriving an area instructed to the area changing unit 106, the method in which the control unit 108 maintains the aspect ratio of the playback video area has been described. However, the present invention is not limited to this, and even when the aspect ratio is changed, it is possible to realize a display in which a banner does not overlap an important video. For example, the control unit 108 changes the playback video area so that it does not overlap the banner in the vertical direction, but performs resolution conversion on the current video in the horizontal direction to change the display on the display unit 107 to a video display that extends horizontally. May be. In addition, when banner display is performed while the entire area is displayed, the control unit 108 gives an example of overlaying a banner on the displayed video. Similarly, resolution conversion is performed without maintaining the aspect ratio so as not to overlap the banner. Can also be done. In the present embodiment, as a method of deriving an area to be instructed to the area changing unit 106, the control unit 108 has been described as instructing to enlarge the reproduction video area in the upward direction overlapping the banner. However, the size in the horizontal direction can be changed as long as the area before the change, that is, the area specified by the coordinates (1921,1081) and coordinates (5760,3240) shown in FIG. You can do it. For example, the control unit 108 changes the area defined by the coordinates, the coordinates (1,1081) and the coordinates (5760, 4320) within the entire area, so that no area is displayed in the display area. Display control can be realized.

  In the above description, an example has been given in which a banner is displayed as a second video to be combined with a first video to be displayed. However, instead of the banner, a menu (including a GUI or the like), picture, symbol Of course, the same processing can be performed even if the notification video is. The second video may be a video input from a digital television broadcast program or an external input terminal, and may be displayed simultaneously on the same screen by PinP (Picture in Picture).

  As described above, even when a banner is combined with a video and displayed, the user can change the playback video area so that the banner does not overlap the important video currently displayed. You can prevent it from being overlooked. Furthermore, even if the recommended view angle or user view angle is changed during the display of a banner or the like, by changing the display being played back to the latest recommended view angle or user view angle, You can continue to watch important video.

  Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the configuration example of the broadcast receiving apparatus is the same as that in FIG. 1, and hereinafter, the processing of the control unit 108 will be described focusing on the differences from the first embodiment. In the second embodiment, another control example is shown for the processing of S804 to S806 in the flowchart of FIG. 5 according to the first embodiment. That is, an example of control for changing the region so that the recommended angle of view and the banner do not overlap and an example of control for preventing a region lacking a video from appearing in the display region will be described.

  In the flowchart of FIG. 5 according to the first embodiment, another example of the control unit 108 regarding S804 to 806 will be described in detail with reference to the flowchart of FIG. After starting in step S1101, in step S1102, the reproduction unit storage unit 111 stores information on the region instructed by the control unit 108 to the region change unit 106. In next step S1103, the control unit 108 determines whether or not the region instructed to the region changing unit 106 is the entire region. As a result, when it is determined that the area instructed to the area changing unit 106 is the entire area, the process proceeds to S1106 described later. On the other hand, if the video is displayed at the recommended angle of view, the process proceeds to S1104.

  In S1104, similarly to the processing in S806 described in the first embodiment, the control unit 108 performs region derivation processing, and instructs the region changing unit 106 to change to the derived region. In next step S1105, the control unit 108 determines whether or not the derived area is wider than the entire area. As a result, if it is determined that the derived area is wider than the entire area, the process proceeds to S1107, which will be described later. If not, the process proceeds to S1108 and the process ends.

  In step S1106, the control unit 108 determines whether or not recommended view angle information is obtained. As a result, if the control unit 108 determines that the recommended view angle information is not obtained, the process advances to step S1108, and the control unit 108 terminates the control without issuing an area change instruction to the area change unit 106. Further, when the control unit 108 determines that the recommended view angle area is obtained as a partial area, or when the determination result in S1105 is positive, that is, when the derived area is determined to be wider than the entire area, The process proceeds to S1107.

  In step S1107, the control unit 108 changes the reference of the video that does not overlap the banner. For example, the control unit 108 changes the reference of the video from the video displayed on the display unit 107 to a recommended angle of view. Further, the control unit 108 derives the video area to be changed inside the boundary of the entire area (inner area), and instructs the area changing unit 106 to change to the derived area. Thereafter, the process proceeds to S1108 and the process ends.

  The processing described above will be described with reference to specific examples shown in FIGS. FIG. 8A shows the entire image displayed on the display unit 107, that is, the image in the area defined by the coordinates (1,1) of the lower left corner and the coordinates (7680,4320) of the upper right corner. The area surrounded by the dotted line corresponds to the recommended angle of view. FIG. 8B shows a region where the recommended angle of view does not overlap the banner and is derived around the recommended angle of view when the banner is displayed. The area shown in FIG. 8B is a rectangular area defined by the coordinates of the lower left corner (-959,1) and the coordinates of the upper right corner (4800,3240). Represents. FIG. 8C shows an example of an image in which the area changing unit 106 is instructed by the area changing unit 106 and the resolution is converted and then displayed on the display unit 107 together with the banner. There is a problem that a video missing area is displayed on the display unit 107. Therefore, a method for displaying video in all display areas of the display unit 107 in consideration of such an area where video is missing will be described below.

  FIG. 9A shows that when the banner is displayed, the video with the recommended angle of view is not overlapped with the banner, and the area with the recommended angle of view is arranged at the lower left corner, so that the missing area of the video does not occur. Shows the derived area. The area shown in FIG. 8B has the coordinates of the lower left corner (-959,1) and the coordinates of the upper right corner (4800,3240), and the entire area has the coordinates (1 of the lower left corner as shown in FIG. 8A). , 1) and the upper right corner coordinates (7680,4320). Comparing the two, it can be seen that only the area surrounded by the coordinates (−959,1) and coordinates (0,3240) is located outside the entire area. Therefore, the region of FIG. 8B may be shifted by 960 pixels in the X-axis direction (horizontal direction), and thereby the region of FIG. 9A, which is an offset region, is obtained. That is, the region has the coordinates (1, 1) of the lower left corner and the coordinates (5760, 3240) of the upper right corner. As described above, in addition to the region deriving method described in the first embodiment, the control unit 108 confirms that the coordinates of the region to be changed are positions within the entire region, and derives a region that does not overlap the banner. When the coordinates of the area to be changed are outside the entire area, the control unit 108 displays the video in all the display areas of the display unit 107 by using the derivation method that does not maintain the aspect ratio described in the first embodiment. can do.

  FIG. 9B shows an example of an image displayed on the display unit 107 together with a banner after the control unit 108 instructs the region changing unit 106 of the region in FIG. By the derivation process, it is possible to prevent the occurrence of an area having no video as shown in FIG.

  As described above, according to the second embodiment, in addition to the effects of the first embodiment, the maximum range of the area to be changed is within the entire area, thereby displaying an image over the entire display area of the display device. it can.
