If it is the cooperative control setting, the process proceeds to step S102. If it is not the cooperative control setting, the cooperative control is terminated. In addition, although this setting assumes changing a setting from the input device 110 according to the input operation from a user, you may change a setting by another method.

  In step S102, the terminal approach detection unit 112 detects whether another broadcast receiving mobile terminal device 100 is approaching.

  In step S103, it is determined whether or not the other broadcast receiving portable terminal device 100 performed in step S102 is present at a close position. If the terminal is approaching, the process proceeds to step S104. If the terminal is not approaching, the process returns to step S101.

  In step S104, from the information obtained from any one of the movement amount detection unit 113, the inter-terminal relative position detection unit 114, and the terminal information acquisition unit 115, the own terminal shares the channel (hereinafter referred to as “channel or sharing source”). And a process of determining whether it is a shared side (hereinafter referred to as “channel sharing destination”). Detailed processing in step S104 will be described with reference to FIG.

  In step S105, channel sharing information indicating whether the terminal is a channel sharing source or a channel sharing destination is transmitted to another broadcast receiving mobile terminal device 100 through the inter-terminal communication processing unit 111, and other broadcasts are also transmitted. The channel sharing information is received from the mobile terminal device 100 for reception.

  In step S106, it is determined whether channel sharing control is possible from the channel sharing information of the terminal itself and the channel sharing information received from another terminal in step S105. If channel sharing information from other terminals cannot be received (all other terminals are not in the cooperative control setting), or channel sharing information of other terminals and own terminal are all channel sharing destinations (the receiver is all powered off) In this case, since channel sharing is not possible, the process proceeds to step S101. In cases other than the above, since channel sharing is possible, the process proceeds to step S107.

  In step S107, the current viewing setting content is recorded in the setting information recording unit 116 so that the current viewing setting can be restored after the cooperative control is completed. As the contents to be recorded, setting values of items that may be changed by cooperative control, such as viewing channel, video and audio output settings, and screen layout settings are recorded.

  In step S108, it is determined whether it is a channel sharing source based on the channel sharing determination in step S104. If it is a channel sharing source, the process proceeds to step S110. If it is not the sharing source, the process proceeds to step S109.

  In step S109, according to the cooperative control information received from the channel sharing source as the channel sharing destination, the program channel and the playback setting of the mobile terminal device 100 for broadcast reception are changed.

  In step S110, cooperative control information including another broadcast receiving portable terminal device 100 as a channel sharing source is created and transmitted to each terminal through the inter-terminal communication processing unit 111, and the own terminal is subjected to cooperative control. When the cooperative control information is sent from the channel sharing destination terminal, the cooperative control information is generated and transmitted again, and the cooperative control of the own terminal is performed accordingly. Detailed processing in step S110 will be described with reference to FIG.

  In step S111, setting values of items that may be changed by cooperative control, such as output settings related to viewing channels, video and audio, and screen layout settings, in which the current viewing setting contents are recorded in the setting information recording unit 116 are read. Then, the setting is performed again to return to the viewing setting before the cooperative control.

  FIG. 3 is a detailed diagram of step S104. The information is obtained from any of the movement amount detection unit 113, the inter-terminal relative position detection unit 114, and the terminal information acquisition unit 115. Hereinafter, a process of determining whether the channel is a shared side (hereinafter referred to as “channel sharing destination”) is performed. The process shown in FIG. 3 will be described below.

  In step S201, it is determined whether the broadcast receiving mobile terminal device 100 is viewing a broadcast. When viewing, that is, when the tuner unit 101 is receiving a predetermined broadcast channel, the process proceeds to step S202. When not watching, that is, when the tuner unit 101 is not receiving broadcasts, the process proceeds to step S212, and the own terminal is set as the sharing destination.

  In step S202, it is determined whether the mobile terminal device for broadcast reception 100 performs channel sharing determination in the movement amount determination mode. The movement amount determination mode is a mode in which channel sharing determination is performed based on the latest terminal movement amount, and is set by the user through the input device 110 in advance. If it is in the movement amount determination mode, the process proceeds to step S203. If it is not in the movement amount determination mode, the process proceeds to step S206.

  In step S <b> 203, the latest movement amount of the mobile terminal device 100 for broadcast reception is acquired from the movement amount detection unit 113.

  In step S204, the movement amount acquired in step S203 is transmitted to the other broadcast receiving portable terminal device 100 through the inter-terminal communication processing unit 111, and at the same time, from the other broadcast receiving portable terminal device 100, the channel sharing destination terminal. Receive travel distance.

  In step S205, the movement amount of the own terminal acquired in step S203 is compared with the movement amount of the other terminal acquired in step 204, and it is determined whether the movement amount of the own terminal is large. In this specification, it is described that the terminal with the most movement amount is determined as the channel sharing source. However, if the determination is made using the latest movement amount of the terminal, other determination criteria (for example, “the most recent movement amount” May be less). If the amount of movement is large, the process proceeds to step S212. If the amount of movement is the smallest compared to other terminals, the process proceeds to step S213.

  In step S206, it is determined whether the portable terminal device for broadcast reception 100 performs channel sharing determination in the terminal position determination mode. The terminal position determination mode is a mode in which channel sharing determination is performed based on the relative positional relationship between the broadcast receiving mobile terminal devices 100 such as up and down or left and right, and is set by the user through the input device 110 in advance. . If it is in the relative position determination mode, the process proceeds to step S207. If it is not the relative position determination mode, it is regarded as the viewing history determination mode and the process proceeds to step S209.

  The viewing history judgment mode refers to the program information being viewed and the viewer's viewing, such as matching the shared channel to the channel with the longest viewing time, or matching to the program with the latest end time of the program being viewed. In this mode, channel sharing determination is made based on the history, and is set by the user through the input device 110 in advance. In this specification, the mode is determined in the order of the movement amount determination mode, the terminal position determination mode, and the viewing history determination mode using Step S202 and Step S206. However, the determination mode may be determined in any order.

  In step 207, the relative position information between the mobile terminal devices 100 for broadcasting reception is acquired by the inter-terminal relative position detection unit 114.

  In step 208, based on the relative position information between the broadcast receiving portable terminal devices 100 acquired in step 207, whether or not the own terminal is at a position (for example, below or right) determined in advance by another terminal. Determine. In the present specification, the terminal below is described as being determined as the sharing source, but other determination criteria (for example, right) may be used as long as the determination is made using the relative positional relationship between the terminals. If the position of the own terminal is at the lowest position, the process proceeds to step S213. If the own terminal is not at the lowest position, the process proceeds to step S212.

  In step S209, the terminal information acquisition unit 115 acquires the viewing history of the broadcast receiving mobile terminal device 100 or program information. Although it has been described that the viewing history and program information are acquired from the terminal information acquisition unit 115, it may be acquired directly from the reception processing unit 102.

  In step S210, the viewing history or program information acquired in step S209 is transmitted to the other broadcast receiving portable terminal device 100 through the inter-terminal communication processing unit 111, and at the same time, the other broadcast receiving portable terminal device 100 receives another Receives terminal viewing history or program information.

  In step S211, the viewing history or program information of the own terminal acquired in step S209 is compared with the viewing history or program information of the other terminal acquired in step 210, and the own terminal is determined in advance by another terminal. It is determined whether or not a determination criterion (such as “the longest viewing time” or “the latest end time of the program being viewed” is satisfied) is satisfied. In this specification, the terminal having a longer viewing time is described as being determined as the sharing source. However, if the determination is made using the viewing history or the program information, other determination criteria (for example, “viewing” The end time of the program is the latest "). If the viewing time is the longest compared to other terminals, the process proceeds to step S212. If the viewing time is shorter than other terminals, the process proceeds to step S213.

  In step S212, as a result of performing channel sharing determination in each determination mode, it is determined that the terminal itself is the channel sharing destination.

In step S213, as a result of performing channel sharing determination in each determination mode, it is determined that the terminal is the channel sharing source.

  In this specification, the movement amount, the terminal relative position, and the viewing history are classified into the respective modes and the channel sharing determination is performed. However, the movement amount, the terminal relative position, and the viewing history are respectively weighted, and the respective parameters are set. In consideration of this, a comprehensive sharing decision may be made.

  FIG. 4 is a detailed diagram of step S110, in which cooperative control information including another broadcast receiving mobile terminal device 100 is created as a channel sharing source, transmitted to each terminal through the inter-terminal communication processing unit 111, and the own terminal Perform coordinated control. Further, when the cooperative control information is sent from another terminal, the cooperative control information is generated and transmitted again and the cooperative control of the own terminal is performed accordingly. The process shown in FIG. 4 will be described below.

  In step S301, the terminal information of the broadcast receiving portable terminal device 100 of the channel sharing destination is received by the inter-terminal communication processing unit 111.

  In step S302, it is determined whether or not the broadcast receiving mobile terminal device 100 is set to perform cooperative control of the present invention. If it is the cooperative control setting, the process proceeds to step S302. If it is not the cooperative control setting, the process proceeds to S313.

  In step S <b> 303, the terminal approach detection unit 112 and the inter-terminal relative position detection unit 114 acquire a position relative to the distance of another terminal.

  In step S304, it is determined whether or not the cooperation information is received from the other terminal by the inter-terminal communication processing unit 111, or the input device 110 has changed the settings relating to the reproduction of the broadcast content such as the volume of the own terminal and the viewing channel. To do. Receiving the cooperation information from another terminal means that the setting related to viewing has been changed at the supply destination terminal. That is, when a setting change is made in another terminal or one of its own terminals, it is necessary to create cooperation information again in the mobile terminal device 100 for broadcasting reception from the channel sharing source. If the cooperative information is received or if the setting of the terminal itself is changed, the process proceeds to step S306. When there is no setting change in all terminals, that is, when there is no reception of cooperation information and there is no change in the setting of the own terminal, the process proceeds to step S305.

  In step S305, the distance between the terminals acquired in step S303 is compared with the previously acquired distance to determine whether there is a change. If there is a change in the distance between the terminals, the process proceeds to step S306 in order to create cooperation information again. If there is no change in the distance between the terminals, the process returns to step S303, and the processes from step S301 to step S305 are repeated.

  In step S306, based on the distance between the terminals acquired in step S303, it is determined whether or not the own terminal, that is, the channel sharing source terminal, is within the range of cooperative operation set in advance with other terminals. If another terminal exists at a distance within the range of the cooperative operation, the process proceeds to step S307. If there is no other terminal at a distance within the range of the cooperative operation, the process proceeds to S313, where the cooperative operation of the own terminal is terminated, and the viewing state before the cooperative operation is returned to step S111 in FIG.

  In step S307, the channel received by each terminal, the layout setting such as the size and range of the output video, the content to be output (for example, video, data broadcast, program information), the video setting such as the brightness, etc. Create collaborative information for output settings. Detailed processing of step 307 will be described with reference to FIG.

  In step S308, collaborative information for output setting for audio output, such as audio channels to be reproduced by each terminal, volume, and sound effects, is created. The detailed processing of step 109 will be described with reference to FIG.

  In step S309, based on the relative position information between the terminals acquired in step S303 and the cooperation information related to the screen output generated in step S307, correction of the cooperation information and creation of alignment guide information are performed. If it is possible to shift the output position of the screen between the terminals based on the battle information and position information related to the screen output of each terminal, and the video can be aligned, the output position of each terminal is shifted, and multiple units can The cooperation information is corrected so that the screen display position matches. When it is in a position that can not be handled by changing the output display position of each terminal, a grid line for aligning to each terminal is output, or information that induces terminal position bubbles is output with arrows such as up, down, left, and right Add positioning information to the cooperative information, such as setting.

  In step S310, the output timing for matching the output synchronization timing of video and audio between the terminals based on the terminal information of the other terminal acquired in step S301 and the terminal information of the own terminal acquired from the terminal information acquisition unit 115. Add information to shared information. Depending on the specifications of the broadcast receiving mobile terminal 100, the amount of buffer data for the broadcast data in the terminal, the processing speed of the tuner unit 101, the audio processing unit 103, the video processing unit 105, etc. are different, and even when the same broadcast is received, It may not be played back simultaneously between different terminals. In step S310, in order to match this output timing shift, information such as the latest video or audio output timing or the channel sharing source output timing is added to the cooperation information. As for how to adjust the output timing, it is highly accurate between terminals using clock information such as presentation time information (PTS: Presentation Time Stamp) and system reference time (STC: System Time Clock) included in broadcast data. For example, the output timing may be synchronized with the output timing.

  In step S311, the created cooperative information is transmitted from the inter-terminal communication processing unit 111 to another terminal.

  In step S312, the setting of the mobile terminal device 100 for broadcast reception is changed based on the created cooperative information.

  In step S313, cooperation end information indicating that the cooperative operation is to be ended is transmitted from the inter-terminal communication processing unit 111 to the channel sharing destination.

  FIG. 5 is a detailed diagram of step S307. The channel received by each terminal, the layout setting such as the size and range of the output video, the content to be output (for example, video, data broadcast, program information), brightness Create collaborative information for output settings for screen output, such as video settings. The process shown in FIG. 5 will be described below.

  FIG. 5 is a detailed diagram of step S307. The channel received by each terminal, the layout setting such as the size and range of the output video, the content to be output (for example, video, data broadcast, program information), brightness Create collaborative information for output settings for screen output, such as video settings. The process shown in FIG. 5 will be described below.

  In step S401, a terminal having a display close to or in contact with a certain distance or more is searched based on the information on the relative position between the terminals acquired in step S303, and the video display size ratio (for example, 16: 9 or 4: 3) and the like, and an area in which one video can be displayed on a plurality of terminals without change. The screen searched here becomes the main display screen for sharing and displaying the channel.

  In step S402, in order to display one video content on the maximum display screen configured by a plurality of terminals determined in step S401, the reception channel of the corresponding terminal is set as a shared channel, and the video displayed on each terminal is displayed. Information for setting the area, the magnification, and the display position for each terminal is described in the cooperation information.

  In step S403, it is determined whether there is a display empty terminal that has not been set in the main display area in steps S401 and S402. If there is a display empty terminal, the process proceeds to S404, and the terminal is set to display data broadcasting. If there are no display free terminals, the screen output determination process is terminated.

  In step S404, the channel to be received for the corresponding terminal and the setting of the data broadcast display are added to the cooperative information so that the data broadcast of the shared channel is displayed for one empty terminal.

  In step S405, it is determined whether or not there is a display empty terminal after step S404. If there is a display free terminal, the process proceeds to S406, and the program information is set to be displayed. If there is no free terminal, the screen output determination process is terminated.

  In step S406, the channel to be received and the setting of the program information display for the corresponding terminal are set to the cooperative information so that the program display using the program information such as the electronic program guide and the program list is performed on one display empty terminal. Add to

  In step S407, it is determined whether or not there is a display empty terminal after step S406. If there is a display empty terminal, the process proceeds to S408, and another broadcast channel is received and set to be played back. If there is no free terminal, the screen output determination process is terminated.

  In step S408, the channel to be received for the corresponding terminal and the program playback setting are added to the cooperative information so that the empty display terminal receives and plays back another broadcast channel.

  In step S409, it is determined whether all receivable broadcast channels are displayed based on the cooperation information being created. When all the receivable broadcast channels are displayed, since all the display items in this embodiment have been displayed even when there is a display vacant terminal, the screen output determination process ends. If there are still undisplayed broadcast channels, the process returns to step S407 to try to display other channels.

  In the present embodiment, search and setting are performed in the order of the main maximum field angle video, data broadcast, program information, and display of other channels, but the order and presence / absence of display items may be changed. In addition, other display items such as recorded program information, a mail screen, and a standby screen may be displayed on the empty terminal.

  FIG. 6 is a detailed diagram of step S308, in which collaborative information for setting audio output such as audio channels to be played by each terminal, sound volume, and sound effects is created. Here, the description will be made on the assumption that the audio to be broadcast is 5.1 channels. However, the number of playback channels may be increased or decreased according to the number of channels and terminal specifications. In each step of FIG. 6, the positional information acquired in step S303 is used as the relative positional information between the terminals to be used. The process shown in FIG. 6 will be described below.

  In step S501, the right channel audio playback setting is added to the corresponding information to the corresponding terminal so that the rightmost terminal among the terminals receiving the shared channel outputs the R (right channel) of the audio channel. To do. In the present embodiment, the rightmost terminal is set as the right channel, but the right channel may be determined using another method in consideration of the position of the user.

  In step S502, the left channel audio playback setting is added to the corresponding terminal to the corresponding information so that the leftmost terminal among the terminals receiving the shared channel outputs L (left channel) of the audio channel. To do. In this embodiment, the leftmost terminal is set as the left channel, but the left channel may be determined using other methods in consideration of the position of the user.

  In step S503, it is determined whether or not there is a terminal between the terminals that reproduce the left and right audio channels determined in steps S501 and S502. If a terminal exists, the process proceeds to step S504 in order to assign the corresponding terminal to the voice channel at the front center of the voice. If no terminal exists, the process proceeds to step S505. If the sound source being broadcast does not require the front center audio channel and the terminal audio processing does not require the front center audio channel, steps S503 and S504 are omitted.

  In step S504, the terminal closest to the center between the left and right terminals among the terminals reproducing the left and right audio channels investigated in step S503 is output as the front center audio channel. The audio playback setting of the front center channel is added to the terminal for the cooperation information. In the present embodiment, the most central terminal is set as the front center channel, but the front channel may be determined using another method in consideration of the position of the user.

  In step S505, it is determined whether a terminal exists behind the display screen. If the terminal is present, the process proceeds to step S506 to set to output the rear audio channel. If there is no terminal behind, the process proceeds to step S507. Note that if the sound source being broadcast does not require a rear audio channel and the terminal audio processing does not require a rear audio channel, steps S505 and S506 are omitted.

  In step S506, setting is made so that the rear audio channel is assigned to the rear terminal investigated in step 505. Therefore, the rear left channel is positioned on the rear leftmost terminal, and the rear leftmost channel is positioned. In order to output the rear right channel to the terminal, the audio reproduction setting for the corresponding terminal is added to the cooperation information. In the present embodiment, the left and right audio channels are set for the terminals located on the left and right of the terminals on the back, but the rear channels may be determined using other methods in consideration of the user's position and the like.

  In step S507, the volume settings of all terminals and the settings related to the sound effects are added to the cooperation information. In the terminal to which the audio channel is assigned in the processing from step S501 to step S506, the setting is added to the shared information so that the sound volume and sound are the same as the sharing source. Set mute for other terminals to which no audio channel is assigned. In the present embodiment, the sound volume and sound settings are made uniform, but the sound volume and sound effect may be changed for each playback channel.

  FIG. 7 is a detailed diagram of step S109, in which the program channel and playback settings of the broadcast receiving mobile terminal device 100 are changed according to the cooperative control information received from the channel sharing source as the channel sharing destination. The cooperative control information is setting information for each terminal to perform control by cooperating with other terminals, and for each terminal, an acoustic effect such as broadcast channel, audio channel, volume, and bass emphasis received. Settings related to audio output such as settings, video display area, video scaling settings, settings related to video output such as video effect settings such as brightness, similarly settings related to data broadcast output, settings related to program information display, output of each data Specify items such as timing settings, whether to display video, data broadcasting, program information display, display size, display magnification and display position, and layout of video data to be displayed on the display. Contains information. In addition, when the setting of the own terminal is changed, the content is included in the cooperative control information and transmitted. The process shown in FIG. 7 will be described below.

  In step S601, the terminal information is transmitted to the channel sharing source via the terminal communication processing unit 111.

  In step S602, it is determined whether or not the broadcast receiving mobile terminal device 100 is set to perform cooperative control of the present invention. If it is the cooperative control setting, the process proceeds to step S603. If it is not the cooperative control setting, the process proceeds to S608.

  In step S603, it is determined whether or not cooperation end information indicating that the cooperative operation is to be ended is received from the channel sharing destination terminal. When the cooperation end information is received, the sharing destination cooperation process is ended. If the cooperative information has not been received, the process proceeds to step S604.

  In step S604, it is determined whether or not the cooperation information is received from the channel sharing destination terminal. If the cooperation information is received, the process proceeds to step S605 in order to change the terminal setting according to the content of the received cooperation information. If the cooperative information has not been received, the process proceeds to step S606.

  In step S605, the terminal setting is changed according to the contents of the cooperation information received in step S604.

  In step S606, it is determined whether or not the settings relating to the playback of broadcast content such as the volume of the terminal itself and the viewing channel have been changed from the input device 110. When the setting is changed, it is necessary to create cooperation information again in the mobile terminal device 100 for broadcast reception of the channel sharing source, and the cooperation information is transmitted to the terminal of the channel sharing source. If there is, the process proceeds to step S607. If there is no change in the setting of the terminal itself, the process returns to step S602.

  In step S607, the content of the setting change of the own terminal is transmitted as cooperation information from the inter-terminal communication processing unit 111 to the channel sharing source.

  In step S608, cooperation end information indicating that the cooperative operation is to be ended is transmitted from the inter-terminal communication processing unit 111 to the channel sharing source.

  FIG. 9 is a schematic diagram of an operation example in the present embodiment when two broadcast receiving mobile terminal devices 10 are brought close to each other. FIG. 9 will be described below.

  It is assumed that the broadcast receiving portable terminal 100a receives "Channel A", reproduces broadcast video, audio (right channel, left channel), and data broadcast, and has been set for cooperative control.

  In the scene 1, the broadcast receiving mobile terminal 100b is not performing broadcast or broadcast reception (in this case, the power of the broadcast receiver is turned off), and video, audio, and data broadcast are not reproduced. Assume that cooperative control settings have been made.

  Scene 2 shows a case where the broadcast receiving portable terminal 100b is brought close to the broadcast receiving portable terminal 100a. In step S102, the approach of the terminal is detected, and the cooperative operation is started. In this case, since the broadcast receiving mobile terminal 100b has not received the broadcast, it is determined in step 104 that the broadcast receiving mobile terminal 100a is the channel sharing source and the broadcast receiving mobile terminal 100b is the channel sharing destination. In step S105, the channel sharing information is communicated between the broadcast receiving portable terminal 100a and the broadcast receiving portable terminal 100b. In step S108, each terminal determines that sharing control is possible. In S107, the current viewing state is recorded in the setting information recording unit 116 at each terminal.

  The broadcast receiving mobile terminal 100b performs step S109 as a channel sharing destination, transmits terminal information to the broadcast receiving mobile terminal 100a, waits for reception of cooperative information from the broadcast receiving mobile terminal 100a, and after receiving the terminal according to the cooperative information Set up. In this example, channel A is selected, the right half of the video of channel A is displayed on the display 109 in full screen, and the right channel is output with the volume adjusted.

  The broadcast receiving mobile terminal 100a performs the process of S110 as a channel sharing source, and after receiving the terminal information from the broadcast receiving mobile terminal 100b, creates cooperative information. Set up the terminal. In this example, while channel A is selected, the left half of the video of channel A is displayed on the full screen on display 109, and the left channel is output as audio.

  The scene 3 shows a case where the broadcast receiving mobile terminal 100b is moved away from the state of the scene 2 within the range of the cooperative control, and the broadcast receiving mobile terminal 100a that is the channel sharing source performs the broadcast receiving mobile terminal in step S303. It detects that the terminal 100b has moved, creates cooperation information again, transmits the cooperation information to the mobile terminal 100b for broadcast reception, and then changes the setting of the terminal itself.

  In this example, the broadcast receiving portable terminal 100b displays the video of the channel A in the normal viewing state on the display 109 while selecting the channel A, and displays the data broadcast in the normal state. Also, the viewing audio is left on the right channel.

  In this example, the broadcast receiving mobile terminal 100a displays the video of the channel A on the display 109 in the normal viewing state while selecting the channel A, and displays the data broadcast in the normal state. Also, the viewing audio is left on the left channel.

  The scene 4 shows a case where the broadcast receiving mobile terminal 100b is moved away from the state of the scene 3 within the range of the cooperative control, and the broadcast receiving mobile terminal 100a that is the channel sharing source performs the broadcast receiving mobile terminal in step S303. 100b is detected, and from step S306, it is determined that the mobile terminal for broadcast reception 100b has moved out of the target of the cooperative operation. In step S313, the cooperation end information is transmitted to the mobile terminal for broadcast reception 100b, and The cooperative control of is terminated.

  In step S111, the setting is returned to the state before the start of the cooperative operation in each terminal, and the initial state is the same as that of the scene 1.

  When the cooperative operation is performed as in scenes 2 and 3, the receiver setting such as the change of the reception channel or the volume of the broadcast reception portable terminal 100a or the broadcast reception portable terminal 100b is performed. Is changed, the cooperative information is created again by the broadcast receiving portable terminal 100a, which is the channel sharing source, and the receiver settings such as channel information change and volume change are reflected on all terminals.

  FIG. 10 is a schematic diagram of an operation example when a plurality of broadcast receiving mobile terminal devices 100 are brought close to each other in the present embodiment. In this example, it is assumed that the sound source is stereo that does not support 5.1ch, and the audio receiving function such as pseudo 5.1ch is not provided in the mobile terminal device 100 for broadcast reception. FIG. 10 will be described below.

  Scene 1 shows the initial state before the cooperative operation. As shown in the figure, each of the five broadcast receiving portable terminal devices 100c, 100d, 100e, 100f, and 100g, 100d indicates channel B, and the others Is watching channel A. Further, the direction of the 100f terminal is reversed, and 100g is a horizontal screen display.

  Scene 2 shows an example of operation when all the terminals are brought closer to 100e than the state of scene 1, and 100e serves as a channel sharing source and other terminals serve as channel sharing destination terminals to perform cooperative control. The sharing source cooperative processing is performed at 100e, and 100e and 100f are assigned to the main display with the maximum field angle from the screen output determination in step S307.

  In step S307, screen allocation is performed so that 100e is displayed on the left side of channel A in step S401 and step S402, and the right side of channel A is displayed in 100f. Here, in consideration of the orientation of the terminal, in 100f, the display direction of the video is rotated to match 100g. Next, in step S404, 100d is assigned to display data broadcasting, in step S406, 100g is assigned to program display, and in step S408, 100c is assigned to normal viewing of another channel (channel B in this example).

  In step S308, 100g is assigned to reproduce the audio right channel in step S501, and 100d is assigned to reproduce the audio left channel in step S502. In step S507, the other terminals 100c, 100e, and 100f are set to a mute state in which sound reproduction is not performed.

  In addition, when any terminal is moved in the state of the scene 2, the content of the cooperative control is changed according to the distance in the same manner as the operation described in FIG.

  When the setting of any terminal is changed in the state of scene 2, the setting is reflected on each terminal in the same manner as the operation described in FIG.

  As described above, according to the present embodiment, each terminal is brought closer by being applied to a mobile phone terminal, a portable information terminal, a mobile PC, an in-vehicle receiving device, a portable receiving device, etc. having a broadcast receiving function.
