When receiving the notification of the completion of the decoding process from the broadcast data receiving circuit unit 110, the audio and video signals obtained from the broadcast data receiving circuit unit 110 are sent to the subordinate Audio circuit unit 122 and the Video circuit unit 123. Control for inputting and outputting the audio signal as sound and control for outputting the video signal as video may be performed. Therefore, the sound of the program displayed on each monitor is reproduced from the speaker in each panel area. In the multi-channel playback mode, menu items for switching programs may be prepared on each screen.

  Next, the single channel playback mode will be described. The single channel playback mode is a mode for broadcasting one program using a maximum of four screens. Note that the number of screens to be used may be any number from 1 to 4, such as using only one screen among the four screens. In the single channel playback mode, only the program displayed on a certain monitor is displayed. In the present embodiment, in the single channel playback mode, a multi-view (multi-angle) of up to 3 angles can be displayed. In addition, a 5.1ch surround playback mode is prepared as an option mode.

  When the single channel playback mode is selected, the panel control unit 121 uses the channel resources allocated to the panel control unit 121 of the broadcast data receiving circuit unit 110 or the panel control unit 121 serving as a master. Based on the obtained audio signal and video signal of the designated program, audio and video may be output to the speaker 14 and the monitor 13 arranged in the corresponding panel area.

  When the multi-view playback mode is further selected in the single channel playback mode, the corresponding panel area is displayed based on the video signal of the specified angle included in the obtained video signal of the specified program. The image may be output to the monitor 13 provided.

  When the 5.1 channel surround playback mode is further selected in the single channel playback mode, the master panel control unit 121 sends the audio signal of the designated program obtained to the rear speaker control unit 131. Control for transferring at least the audio signal of the audio component classified for the rear speaker may be performed. The rear speaker control unit 131 may output audio to the speaker 14Re based on the audio signal of the audio component classified for the rear speaker obtained by the transfer control by the panel control unit 121 serving as the master.

  Each panel control unit 121 can output audio to the speaker 14 provided in the corresponding panel area based on the audio signal of a predetermined audio component included in the obtained audio signal of the designated program. That's fine.

  For example, it is assumed that an operation to shift to a single channel playback mode is performed by a user in a panel area where a certain program is being viewed. The panel control unit 121 corresponding to the panel area receives the operation instruction via the touch panel I / F 124 or the like. The panel control unit 121 recognizes that the single channel playback mode is selected at the initiative of the panel area, and indicates that the program being viewed in the panel area is instructed to shift to the single channel playback mode using the panel control unit 121 as a master. Along with the information, other panel control unit 121 is notified.

  Then, bus transfer control for transferring the audio signal and video signal from the associated broadcast data receiving circuit unit 110 to a buffer included in another control circuit unit 120 is executed. Note that when the other control circuit units 120 receive broadcast data of the same program from the broadcast data receiving circuit units 110 associated with each other, transfer control is not necessary.

  Here, when the multi-view playback mode option is selected, the broadcast data receiving circuit unit 110 may be controlled to receive the same program corresponding to the multi-view. When the 5.1ch surround playback mode option is selected, the broadcast data receiving circuit unit 110 may be controlled to receive the same program corresponding to 5.1ch surround. When the 5.1ch surround playback mode option is selected, the master panel control unit 121 sends a notification to the effect that the panel control unit 121 shifts to the 5.1ch surround playback mode as another master. A bus for notifying not only the panel control unit 121 but also the rear speaker control unit 131 and transferring the audio signal and video signal from the associated broadcast data receiving circuit unit 110 to a buffer included in the rear speaker control unit 130 Execute the transfer control.

  In the single channel playback mode, menu items for switching angles may be prepared on each screen. In addition, menu items for switching programs and menu items for selecting modes may be prepared. When a menu item for switching programs is selected, the panel control unit 121 corresponding to the selected panel area may become the master panel control unit 121 and perform the same processing.

  In response to the notification from the master panel control unit 121, the other panel control unit 121 controls, for example, the corresponding broadcast data reception circuit unit 110 to stop reception, and performs bus transfer control by the master panel control unit 121. The audio signal and the video signal transferred to the subordinate buffer are input to the subordinate audio circuit unit 122 and the video circuit unit 123, and the audio signal is converted into sound and output from the speaker 14 at the connection destination. Control may be performed so that the image is output to the connection destination monitor 13.

  Here, for example, when the multi-view playback mode option is selected, a video signal of an angle designated by the user (or an initial setting) is extracted from a group of video signals to be transferred, and a subordinate Video circuit is extracted. What is necessary is just to input into the part 123. For example, when the 5.1ch surround playback mode option is selected, an audio signal of a predetermined audio component is extracted from a group of transferred audio signals and input to the subordinate Audio circuit unit 122. Good.

  In addition, when receiving broadcast data of the same program from the broadcast data receiving circuit units 110 associated with each other, each of them receives a designated program corresponding to multi-view and broadcast data corresponding to 5.1ch surround. Channel switching may be controlled. In addition, when the designated program corresponding to the multi-view extends over a plurality of channels, the channel switching may be controlled so as to receive broadcast data including a video signal of a desired angle of the notified program. When receiving the notification of the completion of the decoding process from the broadcast data receiving circuit unit 110, the audio signal and the video signal obtained by decoding from the broadcast data receiving circuit unit 110 may be received. The operation after the reception is the same regardless of the presence or absence of transfer control. Further, the angle switching control itself can be executed even in the multi-channel playback mode.

  The rear speaker control unit 131 extracts an audio signal of a predetermined audio component from data transferred to the subordinate buffer by the bus transfer control by the master panel control unit 121 and inputs the audio signal to the subordinate audio circuit unit 122. Then, the control for outputting from the connected speaker 14 may be performed.

  Note that the predetermined audio component in the 5.1ch surround playback mode is an audio component classified for the subwoofer speaker in the case of the panel control unit 121 of the control circuit unit 120CR. In the case of the panel control unit 121 of the control circuit unit 120CL, the audio component is classified for the center speaker. In addition, in the case of the panel control unit 121 of the control circuit unit 120SL, the audio component is classified for the L-side front speaker. In addition, in the case of the panel control unit 121 of the control circuit unit 120SR, the audio component is classified for the R-side front speaker. In the case of the rear speaker control unit 131, the audio component is classified for the rear speaker.

  In the 5.1ch surround playback mode, each panel control unit 121 may select a video signal so that the same program is displayed at a normal angle on four screens. In addition, one program may be divided into four screens on four screens, and a video signal corresponding to the positional relationship of the panel areas may be extracted from the blocks divided into the respective screens. Note that it is also possible to display one program in three angles and display one of the two divided in the panel areas 10CR and 10CL.

  That is, according to the present embodiment, the mobile phone 1 has a pair of a pair of a pair of a pair of a pair of a pair of main panels (main casing unit 11C) having a front surface in the form at the time of calling.
