DESCRIPTION JP2012147235
In a television receiver, it is not necessary to perform a setting operation for selecting an output
destination (speaker) of an audio signal each time a user switches an apparatus (input source) of
an input source of a video signal. An audio output destination setting screen for setting an output
destination of an audio signal received from a video reproduction apparatus such as a BD player
to either an AV amplifier or a main body speaker and a remote control are provided, and an input
of the video signal is performed. When the original device is switched to a certain video
reproduction device (YES in S1), the output destination of the audio signal received from this
video reproduction device is switched to the output destination set using the audio output
destination setting screen (S3 to S11). As a result, every time the user switches the device from
which the video signal is input to a certain video reproduction device, it is not necessary to
perform the setting operation for selecting the output destination of the audio signal received
from the video reproduction device. [Selected figure] Figure 2
Television receiver
[0001]
The present invention relates to a television receiver that is HDMI-connected to an amplifier
device and can output an audio signal received from a video reproduction device to a speaker
connected to the amplifier device.
[0002]
2. Description of the Related Art Conventionally, in a television receiver (hereinafter referred to
09-05-2019

as a TV receiver) capable of connecting to an amplifier device and an HDMI (High-Definition
Multimedia Interface), a main body speaker on the TV receiver side (TV receiver device using
CEC function Among the speakers (built-in or directly connected to the main body) and the
speakers connected to the amplifier device, there are many in which the user can select whether
to output the audio from which speaker (for example, see Patent Document 1) .
In the conventional TV receiver of this type, when the user performs a setting operation for
selecting (the speaker of) the amplifier device in the above-described speaker selection process
(selection process of audio output destination), There are many specifications that turn on / off
the power source on the amplifier device side in conjunction with the power source on / off on
the TV receiver side, making it possible to substantially eliminate the need for the user to operate
the amplifier device. .
[0003]
However, the user does not always want to output the sound from the speaker of the amplifier
device. Specifically, for example, when the input source (input device) is a video reproduction
device such as a BD (Blu-ray Disc) player, it is desirable to listen to the powerful sound output
from the speaker of the amplifier device. When viewing a television broadcast (when the input
source is a tuner and a decoder built into a TV receiver), it is often considered that the sound
from the main body speaker on the TV receiver side is sufficient. However, in the conventional
TV receiver, after the user performs the setting operation for selecting (the speaker of) the
amplifier device in the above-described speaker selection process (selection process of the audio
output destination), the TV receiver When the power source is in the on state, audio is always
output from the speaker of the amplifier device regardless of the input source (regardless of
which input device the audio signal is transmitted from). Therefore, in order to cause the user to
output sound from the main body speaker on the TV receiver side when viewing the TV receiver,
a setting operation for selecting the main body speaker on the TV receiver side is performed. I
needed it. In other words, the main unit speaker on the TV receiver side every time the user
switches the input source (device from which the video signal is input) from the video
reproduction device such as a BD player to the tuner (and decoder) built in the TV receiver. It
was necessary to do setting operation to select. Therefore, the conventional TV receiver of this
type has a problem that the operability at the time of selecting a speaker (selecting an audio
output destination) is poor.
[0004]

By the way, in the AV system including this type of TV receiver, when the power of the amplifier
device is turned on, it is judged that the use of the external speaker connected to the amplifier
device is selected, and the main speaker of the TV receiver is muffled On the contrary, when the
power of the amplifier device is turned off, it is known that the use of the main speaker of the TV
receiver is selected and the mute state of the main speaker is released (see Patent Document 2). .
However, in the present invention, in order for the user to select the speaker (to select the audio
output destination), an operation to turn on or off the power of the amplifier device is required. I
can not solve the problem.

[0028]
Next, with reference to a flowchart of FIG. 2, an audio output destination switching control
process performed to switch the output destination of the audio signal received from the BD
player 3 in the TV receiver 1 will be described. When the user performs the power on operation
of the TV receiver 1 or the switching operation of the device from which the video signal is input
using the remote control 24 (YES in S1), the CPU 11 of the TV receiver 1 operates the input
switching unit 16. The control signal is sent to the device to set the device that is the input
source of the video signal to the device that is the input source of the video signal at the previous
power off when the power is turned on, and to switch the device that is the input source Switch
the device of the input source of to the device of the input source according to the switching
operation. Thereafter, the CPU 11 detects whether or not the video signal is input from the
device of the input source after the switching process (or setting process) by the input switching
unit 16.
[0029]
If a video signal is input as a result of the above detection (YES in S2), the CPU 11 switches the
input switching unit based on setting data of the output destination of the audio signal in the
audio output destination setting table 27 in the memory 26. Switch the output destination of the
audio signal received from the device of the input source after the switching process (or setting
process) by S16. Specifically, for example, when the device of the input source after the above
switching process (or setting process) is the BD player 3, the CPU 11 controls the audio signal of
the BD player 3 in the audio output destination setting table 27. It is confirmed whether the
setting of the output destination of is the AV amplifier 2 or not. As a result, if the AV amplifier 2
is selected (YES in S3), the AV amplifier 2 issues (sends) a voice valid command (command for
09-05-2019
10
instructing to output voice) (S4).
[0030]
The CPU 41 of the AV amplifier 2 receiving the above command turns on the power of its own
device when in the standby state at that time, and when it is in the power-on state at that time,
the power of its own device Leave on. Then, the CPU 41 of the AV amplifier 2 returns to the TV
receiver 1 a response for notifying that it is possible to output audio. When receiving the
response from the AV amplifier 2 (YES in S5), the CPU 11 of the TV receiver 1 sets the output of
the main body speaker 22 to the off state (mute state) (S6). Then, the CPU 11 of the TV receiver
1 starts outputting the audio signal from the audio output unit 31 to the AV amplifier 2 via the
optical digital cable 6 so that the AV amplifier 2 starts outputting the audio from the speaker 61.
(S7).
[0031]
In the determination (confirmation) process of S3, when the setting of the output destination of
the audio signal is not the AV amplifier 2 (NO in S3), the CPU 11 of the TV receiver 1 turns on
the power of the AV amplifier 2. It is determined whether it is a state (S8). As a result, when the
power of the AV amplifier 2 is in the on state (YES in S8), the CPU 11 of the TV receiver 1 causes
the AV amplifier 2 to turn off the power of the power off command. ) Is issued (sent) (S9). Having
received this command, the CPU 41 of the AV amplifier 2 turns off its own power supply. On the
other hand, when the power of the AV amplifier 2 is in the off state (NO in S8), the CPU 11 of the
TV receiver 1 does not issue the power off command to the AV amplifier 2.
[0032]
After the process of S9, the CPU 11 of the TV receiver 1 turns on the output of the main body
speaker 22 (cancels the mute state of the output of the main body speaker 22) (S10), and outputs
the sound from the main body speaker 22 (S11). When the CPU 11 of the TV receiver 1 can not
receive the response from the AV amplifier 2 in the determination process of S5 (when the AV
amplifier 2 receives the voice enable command, the main power is turned off). In the case where
a response is not returned to the TV receiver 1 (NO at S5) due to a cause such as having been
described above, the same processing as S10 and S11 is performed.

[0033]
Next, with reference to FIG. 3, an audio output destination setting screen for registering setting
data of an output destination of an audio signal of each input source (each input device) in the
above-described audio output destination setting table 27 will be described. As shown in the
figure, the audio output destination setting screen 70 displays an audio output destination
corresponding to each input source displayed on the display column 71 of the input source

setting the output destination of the audio signal in the audio output destination setting field 72,
pressing the “1” of the numeric key of the remote control 24 causes the “main body
speaker” to be the output destination of the audio signal. Is set, and the "Amp" (AV amplifier 2)
is set as the output destination of the audio signal by pressing "2" of the numeric key of the
remote control 24. Further, “RF” in the display column 71 of the input source represents the
tuner 14 and the MPEG decoder 15 of the TV receiver 1, and “Video 1” and “Video 2” are
for composite video signal input of the external input unit 30. 1 represents a first video
reproduction device and a second video reproduction device which are connected to the terminal
of the or the component video signal input terminal. “PC” represents a personal computer
connected to the VGA terminal of the external input unit 30. Also, “HDMI 1” and “HDMI 2”
are connected (directly or indirectly via the AV amplifier 2) to the first HDMI terminal and the
second HDMI terminal of the HDMI receiver 29. The first video reproduction device and the
second video reproduction device are shown. The contents set by the user using the audio output
destination setting screen 70 and the remote control 24 are registered (stored) in the abovementioned audio output destination setting table 27 as the output destination of the audio signal
of each input source (each input device) Be done.
[0034]
The BD player 3 described above is indirectly connected to the TV receiver 1 via the AV amplifier
2 and corresponds to the video reproduction device of the HDMI 1 in FIG. Further, the audio
output destination setting screen 70 and the remote control 24 correspond to the audio output
destination setting means in the claims. Although FIG. 3 shows an example in the case where six
types of video reproduction devices are connected as an input source of the TV receiver 1, an
example shown in FIG. 1 is shown as an input source of the TV receiver 1. , “RF” (the tuner 14
of the TV receiver 1 and the MPEG decoder 15) and “HDMI 1” (BD player 3) are connected.
Further, as shown in FIG. 3, when a plurality of video reproduction devices are connected to the
TV receiver 1, the user uses the remote control 24 to turn on the power of the TV receiver 1 or
the video signal. When the switching operation of the input source device (video playback device)
09-05-2019
12
is performed, the CPU 11 of the TV receiver 1 sets the output destination of the audio signal
received from the video playback device (input source) made the input source after switching to
Output destination of the audio signal (of the corresponding input source) set by the user using
the output destination setting screen 70 and the remote control 24 (corresponding to setting
data of the output destination of the audio signal stored in the audio output destination setting
table 27 Control to switch to the output destination).
[0035]
As described above, according to the TV receiver 1 of the present embodiment, when the device
that is the input source of the video signal is switched to, for example, the BD player 3, the
output destination of the audio signal received from the BD player 3 is Automatically at the
output destination of the audio signal of the BD player 3 ("HDMI 1"), which is set by the user in

in the audio output destination setting table 27) Since switching is performed, unlike the
conventional case, every time the user switches the device (input source) from which the video
signal is input to the video reproduction apparatus such as the BD player 3, the output
destination of the audio signal received from the video reproduction apparatus is selected. There
is no need to perform setting operations. Therefore, as compared with the conventional television
receiver of this type, the operability at the time of selecting the output destination of the audio
signal can be improved.
[0036]
Also, when the device from which the video signal is input is switched to the BD player 3, the
output destination of the audio signal of the BD player 3 set by the user using the audio output
destination setting screen 70 and the remote control 24 is the AV amplifier If it is not 2, the
power supply of the AV amplifier 2 is switched off. Therefore, it is possible to reduce the power
consumption in the entire AV system 10 including the TV receiver 1, the AV amplifier 2 and the
BD player 3.
[0037]
Furthermore, according to the TV receiver 1, when the device that is the input source of the
video signal is switched to the tuner 14 (and the MPEG decoder 15), the output of the audio
signal generated by the tuner 14 and the MPEG decoder 15 The destination is automatically
switched to the output destination (the output destination corresponding to “RF” in FIG. 3) of
09-05-2019
13
the tuner 14 and the MPEG decoder 15 set by the user using the audio output destination setting
screen 70 and the remote control 24. Therefore, unlike in the prior art, each time the user
switches the device that inputs the video signal to the tuner 14 (and the MPEG decoder 15), the
user selects the output destination of the audio signal generated by the tuner 14 and the MPEG
decoder 15. There is no need to perform setting operations.
[0038]
Further, according to the present TV receiver 1, as in the example shown in FIG. 3, when
connected to a plurality of video reproduction devices, the device from which the video signal is
input is one of the plurality of video reproduction devices. When switched to another device, the
output destination of the audio signal received from the video reproduction device (hereinafter
referred to as input source video reproduction device) as the input source after switching is the
audio output destination setting screen 70 and the remote control 24. The user can switch to the
output destination of the input source video reproduction apparatus previously set by the user
(stored in the audio output destination setting table 27) using It is not necessary to perform
setting operation for selecting the output destination of the audio signal received from the input
source video reproduction device each time the input source video reproduction device is
switched to the above.
