base SL, a slave CPU is mounted, and an audio circuit, a touch panel I / F, a video circuit, and a
buffer are mounted in a manner attached to the slave CPU.
[0050]
In the example shown in FIG. 4, the mobile control unit 105 is realized by the master CPU.
Further, the panel control unit 121 of the control circuit unit 120CR is realized by the slave CPU
2 mounted on the panel base C-1. The panel control unit 121 of the control circuit unit 120CL is
realized by the slave CPU 1 mounted on the panel base C-1. The panel control unit 121 of the
control circuit unit 120SR is realized by a slave CPU mounted on the panel base SR. The panel
control unit 121 of the control circuit unit 120SL is realized by a slave CPU mounted on the
panel base SL. One of the two audio circuits mounted on the panel substrate C-1 implements an
audio circuit for portable style, and the other implements an audio circuit of the rear speaker
control circuit unit 130. The rear speaker control unit 131 is realized by using the master CPU as
the portable control unit 105 as well. This is because the speaker 14Re is also used as a call
speaker in the portable style. It is also possible to operate the existing call speaker 16 as the
speaker 14Re without separately providing the speaker 14Re.
[0051]
Also, each slave CPU is connected to a broadcast data receiving circuit and a master CPU via
control signals. Also, the broadcast data receiving circuit and each buffer (a buffer under control
of the master CPU and each slave CPU) are connected via a data signal.
[0052]
Although the example shown in FIG. 4 shows an example in which the broadcast data reception
circuit is mounted on the panel base C-1, the broadcast data reception circuit may be mounted
anywhere. Further, in the case where a configuration capable of receiving broadcast data for one
channel is taken as one unit, it can be mounted as a subordinate of each slave CPU. In such a
case, the buffers may be connected via data signals.

As described above, the master / slave configuration of 5 CPUs enables parallel control of the
existing function and the television viewing function of the mobile phone in real time.
[0054]
Next, the operation of this embodiment will be described.
First, the television viewing mode will be described. In this example, a multi-channel playback
mode and a single-channel playback mode are prepared as television viewing modes.
Furthermore, a multi-view playback mode and a 5.1 ch surround playback mode are prepared as
options for the single channel playback mode.
[0055]
The multi-channel playback mode is a mode in which up to four programs are simultaneously
broadcast using four screens. In the multi-channel reproduction mode, the control circuit units
120CR, 120CL, 120SR, and 120SL respectively associated with the four panel regions 10CR,
10CL, 10SR, and SL independently perform control. For example, a state in which the single
channel reproduction mode from any of the panel areas is not selected may be set as the multichannel reproduction mode.
[0056]
When the multi-channel reproduction mode is selected, panel control section 121 controls the
panel control of broadcast data reception circuit section 110 in accordance with an operation
from the user regarding viewing of a television broadcast provided in the corresponding panel
area. Reception and decoding processing of broadcast data is performed using the channel
resources allocated to the section 121, and based on the obtained audio signal and video signal,
audio is output to the speakers 14 and the monitor 13 provided in the corresponding panel area.
And output the video.
[0057]
For example, in the multi-channel reproduction mode, the panel control unit 121 of each control
10-05-2019
17
circuit unit 120 starts reception of broadcast data to the associated broadcast data reception
circuit unit 110 according to the user operation in the panel area. Control to specify a channel,
control to set a channel for channel selection, control to turn on audio output to the subordinate
audio circuit unit 122, or video to the subordinate video circuit unit 123. Perform ON control of
output.
Note that only initialization processing may be performed until an audio signal or video signal of
broadcast data is obtained. Then, when receiving notification of the decoding processing
completion from the broadcast data receiving circuit unit 110, the audio circuit unit 122 and the
video circuit unit 123 under the control of the audio signal and the video signal obtained from
the broadcast data receiving circuit unit 110 Control may be performed to input and output the
audio signal as audio and control to output the video signal as video. Therefore, from the
speakers in each panel area, the sound of the program displayed on each monitor is reproduced.
In the multi-channel playback mode, menu items for switching programs may be prepared on
each screen.
[0058]
Next, the single channel reproduction mode will be described. The single channel playback mode
is a mode in which one program is broadcasted using up to four screens. The number of screens
used may be any one of 1 to 4, such as using only one of the four screens. In the single channel
playback mode, only a program displayed on a certain monitor is displayed. In the present
embodiment, in the case of the single channel reproduction mode, multi-view (multi-angle) of up
to three angles can be displayed. In addition, 5.1ch surround playback mode is prepared as an
option mode.
[0059]
When the single channel reproduction mode is selected, the panel control unit 121 uses the
channel resource assigned to the panel control unit 121 of the broadcast data receiving circuit
unit 110 or the panel control unit 121 that has become the master. Audio and video may be
output to the speaker 14 and the monitor 13 provided in the corresponding panel area based on
the audio signal and video signal of the designated program obtained.
[0060]
When the multi-view playback mode is further selected in the single channel playback mode, the
corresponding panel area is selected based on the video signal of the designated angle included
10-05-2019
18
in the video signal of the designated program obtained. An image may be output to the deployed
monitor 13.
[0061]
Further, when the 5.1 channel surround reproduction mode is selected in the single channel
reproduction mode, the panel control unit 121 serving as the master is an audio signal of the
designated program obtained by the rear speaker control unit 131. Among the above, control
may be performed to transfer the audio signal of the audio component divided for at least the
rear speaker.
The rear speaker control unit 131 may output the sound to the speaker 14 Re based on the audio
signal of the sound component divided for rear speakers obtained by the transfer control by the
panel control unit 121 as the master.
[0062]
Each panel control unit 121 causes the speakers 14 disposed in the corresponding panel area to
output sound based on the audio signal of the predetermined sound component included in the
audio signal of the designated program obtained. Just do it.
[0063]
For example, it is assumed that the user has made an operation to shift to the single channel
reproduction mode in the panel area while watching a certain program.
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 reproduction mode has been
selected by the panel area led, and the panel control unit 121 is used as a master to shift to the
single channel reproduction mode as the program being viewed in the panel area. The other
panel control unit 121 is notified together with the information.

[0064]
Then, the transfer control of the bus for transferring the audio signal and the video signal from
the broadcast data receiving circuit unit 110 associated with each other to the buffer included in
the other control circuit unit 120 is executed. In the case where broadcast data of the same
program is received from the broadcast data receiving circuit unit 110 associated with each
other control circuit unit 120, transfer control is not necessary.
[0065]
Here, when the multiview reproduction mode option is selected, the broadcast data receiving
circuit unit 110 may be controlled to receive the same program corresponding to the multiview.
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 notifies
the other to notify that the panel control unit 121 is to be the master into the 5.1ch surround
playback mode. 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 reception circuit unit 110 to the buffer provided in the rear speaker control unit 130
Execute transfer control of
[0066]
In the single channel reproduction mode, menu items for switching angles may be prepared on
each screen. In addition, menu items for switching programs or menu items for selecting a mode
may be prepared. When a menu item for switching a program is selected, the panel control unit
121 corresponding to the selected panel area may be the master / panel control unit 121 to
perform the same processing.
[0067]
The other panel control unit 121 that has received the notification from the master panel control
unit 121 controls, for example, the reception stop to the corresponding broadcast data reception
circuit unit 110, and the bus transfer control by the master panel control unit 121. An audio
signal and a video signal transferred to the buffer under the control are input to the audio circuit
10-05-2019
20
unit 122 and the video circuit unit 123 under the control, and control is made to output the
audio signal from the speaker 14 of the connection destination as audio and the video signal
Control may be performed to output an image to the monitor 13 of the connection destination.
[0068]
Here, for example, when the multi-view playback mode option is selected, a video signal of an
angle designated (or initialized) by the user is extracted from the group of video signals to be
transferred, and the subordinate video circuit is extracted. It suffices to input to the part 123.
Also, for example, when the 5.1 ch surround playback mode option is selected, an audio signal of
a predetermined audio component is extracted from a group of audio signals to be transferred,
and is input to the subordinate audio circuit unit 122 Good.
[0069]
When the broadcast data of the same program is received from the broadcast data reception
circuit unit 110 associated with each, the designated program corresponding to the multi view
and the broadcast data corresponding to 5.1 ch surround are to be received. , Channel switching
may be controlled. In addition, when the designated program corresponding to the multi view
spans a plurality of channels, channel switching may be controlled to receive broadcast data
including a video signal of a desired angle of the notified program. Then, when receiving the
notification of the decoding processing completion from the broadcast data receiving circuit unit
110, it is sufficient to receive an audio signal and a video signal obtained by decoding from the
broadcast data receiving circuit unit 110. The operation after the reception may be the same
regardless of the presence or absence of transfer control. The angle switching control itself can
also be performed in the multichannel playback mode.
[0070]
Also, the rear speaker control unit 131 extracts an audio signal of a predetermined sound
component from data transferred to the buffer under control by bus transfer control by the
master panel control unit 121 and inputs the audio signal to the control under the audio circuit
unit 122. Control may be performed to output from the connected speaker 14.

[0072]
In the 5.1ch surround reproduction mode, the video signal may be selected by each panel control
unit 121 so that the same program is displayed at a normal angle on four screens. Alternatively,
one program may be divided into four on four screens, and video signals corresponding to the
positional relationship of the panel area may be extracted from the blocks after division into each
screen. Alternatively, one program may be displayed at three angles, and one angle may be
divided into two by the panel areas 10CR and 10CL.
[0073]
