The first to sixth aspects are as follows.
Any one of the aspects may be individually implemented, or a plurality of aspects may be arbitrarily combined and implemented. It should be noted that this embodiment includes all the first to sixth aspects.

As shown in FIG. 3, the voice setting history data (volume value in this example) fetched by using each of the above-mentioned devices is divided into predetermined types and recorded in the storage section 50. Further, as shown in FIG. 4, the voice setting history data for a specific individual is further for each individual (for each registration number in this example).
And is recorded in the storage unit 50. It should be noted that the voice setting history data always includes the latest voice adjustment data, and the past data is held for a predetermined fixed number or fixed period. In this embodiment, as shown in FIG.
The voice setting history data is stored as valid history data in the addresses up to F so that a maximum of 16 data can be held.

The operator usually uses the remote controller 120 to select and specify a specific situation or condition. At the left end of the remote controller 120, keys 126 related to "volume recording condition" are arranged in a vertical line. The types of keys are "none", "common", "individual", "program", "channel",
There are eight: "time", "noise", and "record deletion". The “none” key 126a serves as a key for setting the initial volume automatic setting to OFF. Also, "common", "individual",
Each of the "program", "channel", "time", and "noise" keys 126b to 126g sets the initial volume automatic setting to ON, and sets the volume by "situation or condition" that is the basis for calculating the initial volume value. The key serves as a key for previously designating the history data as a predetermined data according to the intention of the operator. Furthermore, the "record erase" key 126h is a key that erases all history data described later. The input result of each key is displayed on the display unit 121 of the remote controller 120.

Next, with reference to the flow chart of FIG. 6, a procedure for setting a condition or a condition which is a basis of initial volume value calculation will be described. The remote controller 120 always detects a key press (S1), and if detected, determines whether or not the key is a key related to "volume recording condition" (S1).
2). When a key other than the key related to the "volume recording condition" is detected, the process moves to the corresponding command output as a normal remote control operation (S3). On the other hand, when the key 126 related to the "volume recording condition" is detected, the type of the key is determined, and the process corresponding to each key is performed as follows.

When the "none" key 126a is detected (S4), the remote control command output when the power key 122 of the remote control 120 is pressed is such that only the "power" command is output. Is preset (S5). When the "record erase" key 126h is detected (S6), the remote control command output when the power key 122 of the remote controller 120 is pressed outputs two commands, "power" and "record erase". Then, the remote controller 120 is preset (S7). Similarly, when the "common" key 126b is detected (S8), the "power" and "common" commands are sent (S9), and the "individual" key 1
26c and a "number" (for example, "1") that identifies the individual (26) and the individual are detected (S10), "power",
The three commands of "personal" and "number" (S11),
If the "program" key 126d is detected (S1
2), two commands of "power supply" and "program" (S1
3) If the "channel" key 126e is detected (S14), two commands "power" and "channel" are detected (S15), and if the "time" key 126f is detected (S16). , "Power" and "time" (S17), and when the "noise" key 126g is detected (S18), the two commands "power" and "noise" (S19), respectively. Remote control 1 to output
It is preset to 20.

Next, when the operator turns on the power of the broadcast receiver 130 and starts viewing or listening, the receiver 13 is received.
A procedure for automatically setting the initial volume of 0 will be described with reference to the flowchart of FIG. When the broadcast receiver 130 detects the power command (S30), the power of the broadcast receiver 130 is turned on (S31). However, even if the power is turned on, the audio output is still stopped. Next, the noise signal in the room in which the broadcast receiver 130 is placed is captured by the measurement microphone 110, and FFT (Fast Fourier Analysis) or the like is used based on the noise signal in the calculation / judgment / control unit 60. The background noise level is calculated (S32). Then, "record erase", which is a subordinate command used in combination with the power command,
It is detected whether a command of "common", "individual" + "individual identification number", "channel", "time", or "noise" is sent (S33). If there is no such command, only the normal power-on process is performed on the broadcast receiver 130 (S34).

On the other hand, when the "record erase" command is detected, the power of the broadcast receiver 130 is turned on, and all the volume setting history data recorded in the storage unit 50 is erased. Return the part to the initial state (S3
5, S36). When the "common" command is detected, the volume setting history storage area for "common" is determined as the read address (S37). “Common”
The volume setting history storage area for is provided corresponding to an unspecified operator. When the "individual" command is detected, the volume setting history storage area for "individual" is determined as the read address, and
When the "number 1" command is detected as the "personal identification information", from the volume setting history recording area for each registration number,
The volume setting history storage area for "registration number = 1" is determined as a read address (S38). When the "program" command is detected, category information (sports, news, drama, music, etc.) of the program currently selected and received from the electronic program guide information processed by the data processing unit 30. Is acquired (S39), and the volume setting history storage area for "program" is determined as a read address (S40). If the "channel" command is detected, the channel number information of the program currently selected and received is acquired from the reception processing unit 20 (S4).
1), the volume setting history storage area for "channel"
The read address is determined (S42). Also,
When the "time" command is detected, the clock processing unit 70
From the current time information (S43), apply it to a predetermined time zone group, convert the current time into time zone information, and then set the volume setting history storage area for "time". , As the read address (S
44). Further, when the "noise" command is detected, the background noise level information measured and calculated when the power is turned on and recorded in the storage unit 50 is read out, and the background noise level group is applied to a predetermined background noise level band group. After converting the background noise level information into background noise level band information, the volume setting history storage area for "noise" is determined as a read address (S45).

Subsequently, based on the address of the volume setting history area determined as described above, the volume setting history data recorded therein is read (S46). Then, the arithmetic / judgment / control unit 60 calculates the average value (Σ / n) from the read data (S47), and sends the value to the volume adjustment processing unit 41 of the external output processing unit 40 for setting. (S4
8) The audio output from the speaker 100 is started (S
49). By the above procedure, the "initial volume" at the time of starting viewing or listening is automatically set.

Next, a procedure for recording and updating the volume setting history data used as described above according to conditions and conditions will be described below with reference to the flowcharts of FIGS. 8 and 9. The broadcasting receiver 130 detects the "volume +/-" command that the operator performs regarding the volume increasing / decreasing operation by using the calculation / judgment / control unit 60 while it is turned on (S60). When the "volume +/-" command is detected, the sound volume adjustment processing section 41 in the external output processing section 40 is instructed to perform the volume increase / decrease processing corresponding to the "volume +/-" operation. At the same time, in order to determine whether or not the volume adjustment has been finally decided and the user has started viewing or listening to the received program, the monitoring timer 71 is set to start counting a predetermined time (S61). When the "volume +/-" command is detected again while the monitoring timer 71 is counting, it is determined that the volume adjustment has not been finalized, the monitoring timer 71 is reset, and the counting is performed again (S62, S63). . On the other hand, when the count of the monitoring timer 71 is completed, it is determined that the volume adjustment of the operator is confirmed, and the "volume setting" at that time is acquired from the voice adjustment processing unit 41 in the external output processing unit 40 (S6).
4). The above is the procedure for acquiring the "volume setting" history information when the "volume +/-" command is detected.

Subsequently, the acquired “volume setting” history information is recorded in the storage unit 50. The procedure for recording the "volume setting" history information is as follows. First, the "volume setting" history information that the unspecified operator performed using the broadcast receiver for viewing or listening to the "volume setting" history information. It records in the volume setting history storage area for "common" of FIG. 3 for the purpose of recording the history information of "setting" (S65). As an example of the order of recording, “effective history data 0” is recorded in the area of address 0 of the detailed memory area shown in FIG. When the next “volume setting” history information is acquired, “effective history data 1” is sequentially recorded in the area of address 1. In the case of the area example of FIG. 5, after recording up to the address F, the address 0 is returned to again, the oldest data is overwritten, and the above process is repeated. Up to 16 pieces of history data of volume setting data are held. This number may be set arbitrarily.

"Situation or condition" of initial volume automatic setting
However, when the information of the "registration number" of the individual is sent together with the "individual" by the selection and designation by the operator and is recorded in the storage unit 50 (S66), the latest confirmed "volume setting" history. "Personal" volume setting history storage of FIG. 3 for the purpose of recording history information of "volume setting" performed by a specific operator for viewing or listening using the broadcast receiver. Recording is performed in the area and in the volume setting history storage area of the corresponding registration number shown in FIG. 4 in the same procedure as described above.

Next, the category information (sports, news, drama, music, etc.) of the currently received program is
The history obtained as a result of volume adjustment of the latest confirmed "volume setting" data obtained from the electronic program guide managed by the data processing unit 30 (S68) is recorded. For the purpose of carrying out the above, recording is performed in the same procedure as described above in the volume setting history storage area for "program" of FIG. 3 (S69).

Subsequently, the channel number information of the program currently being received is fetched from the reception processing unit 20 (S70), and the latest confirmed "volume setting" data is transmitted depending on the reception channel. For the purpose of recording the history of the adjustment result, it is recorded in the “channel” volume setting history storage area of FIG. 3 by the same procedure as described above (S71).

Subsequently, the current time information is stored in the clock processing unit 7
It is acquired from 0 (S72), the extracted time information is applied to a predetermined time zone group, converted into time zone information, and the latest confirmed "volume setting" data is viewed or listened to. Recording is performed in the same procedure as described above in the "time" volume setting history storage area of FIG. 3 for the purpose of recording the history of the result of volume adjustment depending on the band (S73).

Further, the measurement microphone 110 is turned on when the power is turned on.
The background noise level band information calculated based on the obtained noise data and recorded in the storage unit 50 is read (S74),
The volume setting history for "noise" in Fig. 3 for the purpose of recording the history of the result of volume adjustment of the latest confirmed "volume setting" data depending on the background noise condition in the viewing or listening environment. It is recorded in the storage area by the same procedure as described above (S75). The above is the recording procedure of the "volume setting" history when the "volume +/-" command is detected, and this processing is repeated while the broadcast receiver is ON.

Under the condition that the adjustment of the volume setting is confirmed, the category of the received program is changed, the channel number of the received program is changed, or the viewing or listening is continued. When the time has passed and the current time has changed from the predetermined time zone managed in the broadcast receiver, the recording processing of the "volume setting" history is performed by the procedure shown in FIG. . That is, after the information of "volume setting" is acquired (S100, S101), the recording is updated by the following procedure.

First, when it is detected that the category of the received program has changed, the latest confirmed "volume setting"
The data is recorded in the "program" volume setting history storage area of FIG. 3 in the same procedure as described above (S102, S103,
S104). When it is detected that the channel number of the received broadcast being viewed or listened to has changed, the latest confirmed “volume setting” data is stored in the “channel” volume setting history storage area of FIG. Recording is performed in the same procedure as described above (S110, S111, S112). Furthermore, when it is detected that the time zone information at the time of viewing or listening has changed, the latest confirmed “volume setting” data is stored in the “time” volume setting history storage area of FIG. Recording is performed in the same procedure as described above (S120, S1).
21, S122). The above is the procedure for recording and updating the volume setting history data for each situation and condition when the category of the received program, the channel number, or the reception time zone changes.

In the above embodiment, the set volume of the receiver calculated from the effective history data is the average value of the recorded effective history data, but what value is based on the effective history data? Whether to set the volume may be arbitrarily determined. For example, an intermediate value of valid history data can be taken, or the latest history data can be used as it is as the set volume.

According to the broadcast receiver of the above embodiment, the past average value of the volume adjustment results recorded as the history for each situation and condition is automatically set as the initial volume when the next viewing or listening is started. Will be set to. As a result, when the broadcast receiver such as a TV is turned on, the volume that is closer to the operator's preference is automatically set, so that the conventional power-on method is applied every time the power is turned on. It is possible to reduce the number of operations and the amount of operations for adjusting the volume by using.
