As shown in FIG. 2B, a volume is set in the storage device 123 in association with the time, and the set contents are stored. In the example shown in the figure, "20:
"00-23: 00" is set as "10% down" and "23: 00-
“5:00” is set to “20% down”.

In this example, after 8 o'clock at night, the volume is reduced by 10% compared to normal time, and at midnight from 11 o'clock to 5 am, the volume is reduced by 20% compared to normal time. Is set. That is, in the above time zone, the volume output from the speaker 118 is 10 times lower than the set value.
It is output at the volume when set at a value smaller by 20% or 20%.

Therefore, during operation of the television system 1, the sound change control device 122 extracts data indicating the current time from the digital broadcast wave received by the antenna 4, acquires the current time, and stores the data in the storage device 123. Refer to the stored settings. Then, if the corresponding setting content is stored, a control signal for lowering the volume is generated according to the setting content and output to control device 111.

In the sound volume setting of FIG. 2B, besides lowering the sound volume by a predetermined ratio, a predetermined allowable sound volume may be set in advance and stored in the storage device 123. . Then, depending on the time zone, if the predetermined volume is compared with the volume being output and the volume is reduced when the volume being output is higher than the predetermined volume, the volume is reduced by a predetermined time for a set time. Can be kept below the value of.

The tuner 124 demodulates the radio wave of the digital broadcast received by the antenna 4 and performs analysis by various processes such as separation and decoding. Then, data indicating the genre of the program broadcast together with the video and audio data of the program and data indicating the current time are output to the audio change control device 122.
