[0034]
The video synthesis unit 630 synthesizes the video signal from the video processing unit 610
and the video signal from the video processing unit 620. The synthesis is performed when
requested by the instruction signal input from the instruction processing unit 430. Note that the
synthesized video signal is displayed on the screen 230 in a form of two-screen display (that is, a
form in which one of the video signals is displayed on any of the divided screens). The instruction
signal can also control how to combine these video signals. When the combining is not required,
the video combining unit 630 outputs the video signal from the video processing unit 610 or the
video processing unit 620 to the video processing unit 640 according to the instruction signal.
[0035]

of the video signal (in other words, the content including the respective video signal) is the same,
the video display on the screen 230 is performed by outputting only the video signal from any
video processing unit to the video processing unit 640. Switch the form from dual screen display
to single screen display. The detection of the two-screen display of the same video may be
performed in the video processing apparatus 600 or may be notified to the video synthesis unit
630 by an instruction signal input from the instruction processing unit 430.
[0036]
Furthermore, the video composition unit 630 detects whether the video signal to be output to the
video processing unit 640 has been subjected to the 3-2 pull-down, when the composition is not
required. When it is detected that the video signal to be output is the 3-2 pull-down, the video
signal is converted so that the display mode of the video becomes wide 1 screen full display

430. The video processing of the video processing unit 640 includes, for example, screen
modification for inserting a black image into the video displayed on the screen 230. Black picture
insertion can be realized by inserting a zero signal into a video signal to be processed. As a black
picture insertion position, for example, the boundary between the divided screen 210 and the
divided screen 220 can be mentioned. In this case, it is possible to clearly identify the video
displayed on the split screen 210 and the video displayed on the split screen 220. Other
examples include the screen 230 or the outline of each of the divided screens 210 and 220. The
width of the black picture to be inserted into the border and the outline is adjustable, and black
size adjustment allows images of various resolutions and sizes to be displayed on the screen 230.

The voice synthesis unit 710 outputs voice signals input from the voice SWs 512 and 522 to the
headphone output terminals 240 and 250 and the speaker 720.
The audio signal output from the audio synthesis unit 710 to the headphone output terminal 240
is either an audio signal from the audio SW 512, an audio signal from the audio SW 522, or an
audio signal obtained by combining these audio signals. The audio signal output from the audio
synthesis unit 710 to the headphone output terminal 250 is either an audio signal from the audio
SW 512, an audio signal from the audio SW 522, or an audio signal obtained by combining these
audio signals. The audio signal output from the audio synthesis unit 710 to the speaker 720 is
either an audio signal from the audio SW 512, an audio signal from the audio SW 522, or an
audio signal obtained by synthesizing these audio signals. The speech synthesis unit 710 controls
which speech signal is to be output to which speech output device according to an instruction
signal input from the instruction processing unit 430. Also, when the voice signal synthesis is
requested by the indication signal, the synthesis rate is indicated by the indication signal.
[0040]
The speaker 720 as an audio output device outputs the audio signal input from the audio
synthesis unit 710 as audio. The speaker 720 can be installed at any appropriate place in the
vehicle cabin.
[0041]
Next, setting information of various tables held in the memory 410 in the control device 400 will
be described. Here, setting information on the speech synthesis rate will be described as an
example with reference to FIG.
[0042]
10-04-2019
12
In the setting information of the voice synthesis rate shown in FIG. 2, “Speaker voice synthesis
rate” is a rate of combining the voice signal output from the voice SW 512 and the voice signal
output from the voice SW 522 of the voice output from the speaker. means. The “headphone A
audio synthesis ratio” means the synthesis ratio of the audio output from the headphone A
between the audio signal output from the audio SW 512 and the audio signal output from the
audio SW 522. The “headphone B audio synthesis ratio” means the synthesis ratio of the audio
output from the headphone B between the audio signal output from the audio SW 512 and the
audio signal output from the audio SW 522.
[0043]
In the present embodiment, the speech synthesis rate is “10: 0”, “9: 1”, “8: 2”, “7: 3”,
“6: 4”, “5: 5”, “4: It can be selected from 6 "," 3: 7 "," 2: 8 "," 1: 9 "and" 0:10 ". The selected
speech synthesis rate is recorded as a set value in the table. Here, “10: 0” indicates the audio
signal itself output from the audio SW 512, and “5: 5” indicates that the audio signal output
from the audio SW 512 and the audio signal output from the audio SW 522 are 1: The audio
signal synthesized at a ratio of 1 means "0:10" indicating the audio signal itself output from the
audio SW 522. In addition, the number of steps of the speech synthesis rate and the level of each
speech synthesis rate can be changed as appropriate.
[0044]
Next, the operation of the AV system 100 having the above configuration will be described.
[0045]
FIG. 3 is a flow chart showing an example of the operation of the instruction processing unit 430
in the case where control is performed to switch the speech synthesis ratio of one of the output
speeches of the speech output device.
Here, while the video of the CD / DVD deck is viewed on the split screen 210 and the video of the
TV tuner 1 on the split screen 220 simultaneously, the headphone output terminal 240 is
connected to the audio output from the CD / DVD deck. It is assumed that the passenger who is
listening in A) has performed an operation using the remote control 310 to listen to the audio
10-04-2019
13
output from the TV tuner 1 together with the audio output from the CD / DVD deck.
[0046]
First, in step S1100, two audio sources for outputting two audio signals to be synthesized are set.
In this example, a CD / DVD deck and a TV tuner 1 are set as two audio sources.
[0047]
Then, in step S1200, the synthesis ratio of the two audio signals input from the two audio
sources set in step S1100 is set. The setting value of the synthesis rate of the two audio signals is
indicated in the operation command input from the operation command input source. The
processing in this step will be described in more detail later.
[0048]
Then, in step S1300, a signal instructing synthesis of the speech signal is output to speech
synthesis unit 710 in accordance with the speech synthesis rate set in step S1200. For example,
if the setting value of the voice synthesis ratio is “8: 2”, the instruction processing unit 430
sets 8: 2 between the audio signal input from the CD / DVD deck and the audio signal input from
the TV tuner 1. An instruction signal to be synthesized at a rate is output to the speech synthesis
unit 710.
[0049]
With the output of this instruction signal, the voice synthesis unit 710 outputs an audio signal
output from the CD / DVD deck and input via the audio SW 512 and an audio signal output from
the TV tuner 1 and input via the audio SW 522. According to the setting value of the speech
synthesis rate set in step S1200, in this example, "8: 2" is synthesized. Then, the voice synthesis
unit 710 continuously outputs the synthesized voice signal to any voice output device, for
example, the headphone output terminal 240. As a result, the ratio of the sound output from the
CD / DVD deck to the sound output from the CD / DVD deck and the sound output from the TV
tuner 1 is 8: 2 from the sound output from the CD / DVD deck Switch to the voice synthesized in.

[0050]
Note that the two audio sources selected in step S1100 do not necessarily have to be the same as
the video sources of the display video of the divided screens 210 and 220. For example, while
viewing the video of the CD / DVD deck and the video of the TV tuner 1 on the split screens 210
and 220, the audio of the CD / DVD deck and the audio of the TV tuner 2 were synthesized by
the headphones connected to the headphone connection terminal 240 It is also possible to listen
to speech.
[0051]
Next, setting of the synthesis ratio of two audio signals will be described.
[0052]
FIG. 4 is a flowchart showing an example of the operation of the instruction processing unit 430
in the case of setting the synthesis ratio of two audio signals.
FIG. 5 is a diagram showing an example of input values of the audio output device to be
controlled indicated by the operation command. FIG. 6 is a diagram showing an example of the
input value of the speech synthesis rate indicated in the operation command. The operation of
the instruction processing unit 430 described here corresponds to the operation of step S1200 in
FIG.
[0053]
First, in step S1210, the operation command from the operation processing unit 420 is acquired.
[0054]
Then, in step S1220, an audio output device to be controlled is identified.
10-04-2019
15
The audio output device to be controlled can be identified by referring to the input value
indicated in the operation command. For example, when the passenger designates headphone A,
an input value "2" is displayed in the corresponding field in the operation command, as shown in
FIG. 5, for example.
[0055]
When the passenger performs some control such as voice synthesis and volume adjustment on
the voice output device, the passenger specifies the voice output device to be controlled by the
operation command and then controls the specified voice output device. The user performs an
operation for pressing the other operation button.
[0056]
Then, in step S1230, the input value of the speech synthesis rate indicated in the operation
command is referred to.
The input value of the speech synthesis rate is defined, for example, as follows. As in the abovementioned example, an audio in which the audio signal output from the CD / DVD deck and the
audio signal output from the TV tuner 1 are synthesized at a ratio of 8: 2 as the output audio
after switching. If is selected, an input value "2" is displayed in the corresponding field in the
operation command as shown in FIG. 6, for example.
[0057]
Then, in step S1240, the setting value of the speech synthesis rate in the setting table is updated
based on the input value of the speech synthesis rate. In this example, in the table shown in FIG.
6, since the set value of the speech synthesis rate is "0", the set value of the speech synthesis rate
is rewritten by changing from "0" to "2". Update the
[0058]
Thus, the synthesis ratio of the two audio signals is set.

The setting of the synthesis ratio of the two audio signals can be individually performed on the
audio output from each audio output device.
For example, the input value "0" of FIG. 6 is set for the output sound of the headphone A, the
input value "2" of FIG. 6 is set for the output sound of the headphone B, and the output sound of
the speaker is output. For that, it is also possible to set the input value "8" in FIG. Thereby, the
passenger can enjoy the voice synthesized from the voice signals from the two voice sources at
the synthesis rate in line with the preferences.
[0060]
As described above, according to the present embodiment, an audio signal formed by combining
audio signals of different content sources can be output as audio from the audio output device.
Thereby, the passenger combines the audio linked to the other video of low interest with the
audio linked to one video of high interest as the main audio of high synthesis ratio among the
videos displayed on the two split screens. As a low rate sub-speech, it is possible to listen to the
synthesized speech.
[0061]
Further, since the voice synthesis ratio can be appropriately changed by an operation command,
it is possible to realize highly convenient voice output according to the needs of the passenger.
For example, while watching a song broadcast on one split screen and watching a song program
on the other split screen, the passenger who is listening to the voice of the song program with
the headphones only outputs the output voice of the headphones during the time when the
baseball is exciting It is possible to change the voice of the baseball broadcast and the voice of
the song program into a voice synthesized at a ratio of 8: 2.
[0062]
In addition, since the voice synthesis rate of the voice signal to be synthesized can be set

individually for each voice output device, the passenger can synthesize the voice signals from the
two voice sources at the synthesis rate in accordance with the preferences. You can enjoy the
voice. As a result, the passenger on the left side of the rear seat listens to the sound of the
baseball broadcast on the headphone A while watching the baseball broadcast on one split
screen, and the passenger on the right side of the rear seat views the news on the other split
screen While, it becomes possible to listen to the voice in which the voice of the baseball
broadcast and the voice of the news are synthesized at a ratio of 2: 8 with the headphone B.

The embodiments of the present invention have been described above. The above description is
an illustration of a preferred embodiment of the present invention, and the scope of the present
invention is not limited to this. For example, in the present embodiment, the case where the AV
system is used as a vehicle-mounted electronic device has been described. However, using the AV
system of the present embodiment alone, an image installed in a narrow space and requiring user
operation It can also be applied to equipment or audio equipment. Further, it is obvious that the
configuration shown in FIG. 1 is an example, and therefore, various changes and modifications of
this configuration example are possible within the scope of the present invention.
[0064]
Further, as another embodiment of the present invention, a program for realizing the function of
each component of the AV system described in the above embodiment is stored in a readable
recording medium, and the program is executed using a CPU. By being implemented, the present
invention can also be implemented. Also, in the two-screen split display, when the voice synthesis
ratio is 10: 0, 9: 1, 8: 2, etc., when the voice of one split screen is output larger than that of the
other, the output is large. A configuration may be employed in which the luminance of the
divided screen according to the person who is outputting the sound is increased.
[0065]
The audio output system, the audio control device, and the audio control method of the present
invention are useful as in-vehicle devices such as an AV system. They are also suitable for
applications outside the cabin, for example for video or audio applications that have a display or
an audio output device and require user manipulation in a narrow space. Can.
