FIG. 2 is a diagram schematically showing the configuration of the setting contents stored in the
storage device 123 of the television system 1. (a) shows the setting contents for the genre, and
(b) shows the setting contents for the time FIG.
As shown in FIG. 2A, in the setting contents of the genre stored in the storage device 123, "code
No." unique to each genre
The "genre name" and the "voice processing" are set in association with each other.
[0061]
08-05-2019
16
For example, audio processing in a mode of "cinema 1" is set to be added to a program belonging
to the genre of "Western film (action)".
In addition, audio processing in the mode of "cinema 2" is set to be added to a program belonging
to the genre of "western music (musical)". Note that "0001-A" is a unique code No. corresponding
to the genre of "Western film (action)". "0001-B" is a unique code No. corresponding to the genre
of "musical". である。
[0062]
Among them, "Cinema 1" mode is audio processing that outputs sound of action movie with a
more powerful sound, for example, and "Cinema 2" mode is audio processing that makes the
sound of musical movie sound more beautiful, for example. It is. In this case, it is possible to
output an audio that has been processed optimally for both action films and musical films.
Furthermore, for example, audio multiplex broadcasting of local language and Japanese is
performed for foreign films, and it is assumed that audio processing different from that of
Japanese images is performed, so audio processing of foreign images and Japanese images
should be set separately. By this, it is possible to output the optimum voice for the program of
each genre.
[0063]
Further, for example, as shown in FIG. 2A, audio processing in a mode of “clear” is set for a
program belonging to the genre of “education (English conversation)”. This "clear" sound
processing is processing for outputting, for example, a sound that makes the human voice clearly
audible, and in this case, the sound of the program for learning English conversation is clearly
and clearly output. Be done.

Therefore, when the user selects the channel on which the action movie is broadcasted by
operating the remote control 51, the code No. “0001-A” is displayed as information indicating
08-05-2019
17
the genre of the program. Are acquired by the voice change control device 122. Then, the setting
content stored in the storage device 123 in association with the “0001-A” is referred to, and
the setting content “cinema 1” is read. Thereafter, a control signal instructing to apply the
audio processing of “cinema 1” is output from the audio change control device 122 to the
control device 111, and the audio subjected to the audio processing of “cinema 1” is output
from the speaker 118 .
[0065]
Further, as shown in FIG. 2B, the volume is set in the storage device 123 in association with the
time, and the setting content is stored. In the example shown in the figure, "20: 00-23: 00" is set
as "10% down", and "23: 00-5: 00" is set as "20% down".
[0066]
In this example, after 8:00 pm, the volume is reduced by 10% compared to the normal time, and
the midnight from 11:00 am to 5:00 am is set to be reduced by 20% compared to the normal
time There is. That is, the above time zone is output at the volume level when the volume output
from the speaker 118 is set to a value 10% or 20% smaller than the set value.
[0067]
For this reason, the voice change control device 122 extracts the data indicating the current time
from the digital broadcast radio wave received by the antenna 4 at the time of operation of the
television system 1, and stores the data in the storage device 123 after acquiring the current
time. Refer to the setting contents. Then, if the corresponding setting content is stored, a control
signal for reducing the volume according to the setting content is generated and output to the
control device 111.
[0068]
In the volume setting shown in FIG. 2B, in addition to lowering the volume by a predetermined
rate, a predetermined volume that may be permitted may be set in advance and stored in the
08-05-2019

storage device 123. Then, depending on the time zone, the predetermined volume is compared
with the volume being output, and if the volume is reduced when the volume being output is
higher than the predetermined volume, the volume is set for only the set time. Can be kept below
the value of
[0069]
The tuner 124 demodulates the radio wave of the digital broadcast received by the antenna 4
and analyzes it by various processes such as separation and decoding. Then, data indicating the
genre of the program to be broadcast together with the video and audio data of the program and
data indicating the current time are output to the voice change control device 122.
[0070]
Next, the operation of the television system 1 configured as described above will be described.
[0071]
First, the television receiver 11 operates according to the operation of the remote control 51, and
data of digital broadcast receivable by the antenna 4 is input to the control device 111.
The controller 111 generates video data and audio data of a predetermined channel from this
data, and the monitor display 117 and the speaker 118 output video and audio based on these
data.
[0072]
Here, when the video and audio of the program being broadcasted on the predetermined channel
are output by the television receiver 11, the data indicating the genre of the program being
output by the television receiver 11 is processed by the tuner 124 in the audio control device 12.
It is analyzed and input to the voice change control device 122.
[0073]
08-05-2019
19
The voice change control device 122 determines whether the corresponding setting content is
stored in the storage device 123 for data indicating the genre of the program.
When the setting content corresponding to the genre of the program being output by the
television receiver 11 is stored in the storage device 123, the control signal for controlling the
sound based on the setting content is the voice change control device 122, and output to the
controller 111.
[0074]
The control device 111 generates a signal indicating audio processing to be added to the audio
output from the speaker 118 according to the control signal input from the audio change control
device 122, and outputs the signal to the audio control circuit 116. The audio control circuit 116
performs specified audio processing on the audio data input from the control device 111
according to the signal input from the control device 111 to drive the speaker 118 to output
audio.
[0075]
For example, as shown in FIG. 2A, in the case where audio processing of “cinema 1” is set in
association with the genre of “Western film (action)” and stored in the storage device 123, a
television receiver may be used. When a foreign action movie is output by the machine 11, the
audio processing of "Cinema 1" is designated by the signal output from the control device 111 to
the audio control circuit 116, and the audio control circuit 116 specifies "Cinema 1". Audio
processing is performed.
[0076]
Further, at the time of operation of the television system 1, a signal indicating the current time
from the digital broadcast radio wave received by the antenna 4 is input to the voice change
control device 122 by analysis by the tuner 124.
The voice change control device 122 determines whether or not the corresponding setting
content is stored in the storage device 123 with respect to the input current time, and the
corresponding setting content is stored in the storage device 123. A control signal instructing
08-05-2019
20
voice processing based on the setting content is output from the voice change control device 122
to the control device 111.
[0077]
Then, as in the above-described operation, the audio control circuit 116 performs audio
processing, and the processed audio is output from the speaker 118. For example, as shown in
FIG. 2B, when the setting to decrease the volume by 20% is performed during “23: 00-5: 00”,
the sound change control device 122 from the tuner 124 is set. If the current time input to the
terminal is between "23:00-5:00", the voice change control device 122 instructs the voice change
control device 122 to output voice at a volume 20% lower than normal. It is output. As a result,
sound is output from the speaker 118 at a volume that is smaller by a predetermined rate than in
normal times.
[0078]
As described above, according to the television system 1 in the first embodiment of the present
invention, the antenna 4 for receiving digital broadcast is provided, and data of broadcast
contents received by the antenna 4 is analyzed by the tuner 114 and further controlled The
apparatus 111 generates video data and audio data, and based on the video data and music data,
the display control circuit 115 and the audio control circuit 116 drive control the monitor
display 117 and the speaker 118 to output video and audio. Television system 1. During the
operation of the television system 1, the voice control device 12 acquires the genre of the
program being output by the television receiver 11 and the current time by the tuner 124 from
the digital broadcast radio wave received by the antenna 4 and stores the storage device in
advance. The setting content stored in 123 is referred to. Then, when audio processing such as
adjustment of sound volume is set in association with the acquired genre of the program or the
current time, control to instruct the control device 111 to apply an effect to the sound from the
audio change control device 122 A signal is output, audio processing is added by the audio
control circuit 116 in accordance with an instruction from the control device 111, and the
processed audio is output from the speaker 118.
[0079]
Therefore, the audio output from the speaker 118 is processed depending on the time zone in
08-05-2019
21
which the television system 1 is used and the genre of the program to be output, even if the user
is not particularly aware. Here, the processing applied to the voice includes, for example,
processing to reduce the sound volume by a certain ratio, processing to increase the sense of
reality, processing to change to a sound that makes the user feel powerful, or processing to
increase the sound of the deep bass range It can be mentioned.
[0080]
In this way, since audio processing can be performed according to the genre of the program to be
output, it is possible to output the audio subjected to the optimum processing only by outputting
the desired program without performing special operations. Programs can be enjoyed effectively.
In addition, since the process of automatically reducing the sound volume is performed in a
specific time zone, it is possible to view while considering the surroundings without the user
performing a particular operation.
[0081]
Furthermore, since the voice control device 12 in the above-mentioned television system 1
becomes operable by connecting to the television receiver 11 and the antenna 4, the television
system can be implemented by attaching the voice control device 12 to the conventional
television receiver 11. 1 is easily achievable.
[0082]
In the television system 1 according to the first embodiment, the setting content of the audio
processing is stored in the storage device 123 in association with the genre of the program
output by the television receiver 11 and the time when the television system 1 operates.
However, the contents stored in the storage device 123 may be settable by the user using the
remote control 51 or 52, or may be set in advance by default.
In addition, the sound processing may be turned on / off based on the setting content stored in
the storage device 123 by the remote control 51, 52, and other detailed configurations may be
changed as appropriate.
[0083]

Further, FIG. 2A shows, as an example, audio processing in each mode of "cinema 1", "cinema 2",
"hole 1" and "clear", but the present invention is limited to this It may be made to be able to
perform sound processing which realizes not only a thing but more various effects. Further, it is
also easy to perform more complicated settings for the setting time and volume setting shown in
FIG. 2B, and it is of course possible to have a configuration that can be arbitrarily set by the user.
