Regarding the volume setting method.

[0002]

2. Description of the Related Art A conventional television does not have a volume setting function when the power is turned on. Therefore, the volume when the power is turned on is set to the volume when the power was turned off last time.

[0003]

In the conventional television, since the volume when the power is turned on is maintained at the volume setting state when the power is turned off, the power is turned off while listening to a large volume. In this case, a loud sound is produced when the power is turned on, even if the loud sound is emitted at midnight or the like, even if the surroundings are disturbed. Further, when the power is turned off while listening to the sound at a low volume, it is inevitable that the volume is low and the sound cannot be heard when the power is turned on even in a time period when ambient environmental noise such as daytime is large.

The object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a volume setting method when the power is turned on, which automatically adjusts the volume when the power is turned on in the television.

[0005]

A volume setting method at power-on according to the present invention is a time-to-volume volume preset in a television having a microprocessor and a clock function in correspondence with the volume of the television in correspondence with a time zone. An information table is provided, and the volume can be set based on the current time and the time-volume information table when the television is turned on.

Also, the volume setting method at power-on of the present invention has a structure that allows the time-volume table to be freely rewritten on the menu screen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention. In this embodiment, a volume control section 1 for inputting a television audio signal 101 and controlling the volume thereof, and a television image signal 1 are provided.
02 and a screen relating to time-volume, a display control unit 2 for performing display control, and a speaker 3 of the television itself.
And a display unit 4 of the television itself using a display such as a CRT or LCD, a CPU 5 as a central processing unit of a microprocessor for making various settings, and a time-volume information table of known contents set in advance. It is provided with a ROM 7, a RAM 7 for writing the change contents of the time-volume table, a clock unit 8 as a clock function of a television situation, and an input unit 9 as an input keyboard for changing the time-volume table.

Next, the sound volume setting operation at power-on of this embodiment will be described.

When the power of the television is turned on, the RAM
It is checked with an error code such as CRC or BCC whether the contents of the time-volume information table shown in FIG. If it is wrong, it is checked with a similar error code whether the contents of the time-volume information table of the ROM 6 are damaged. If ROM6 is also wrong,
Turn on the power at the same volume as when the power was last turned off.

When it is confirmed that the contents of the time-volume information table in the RAM 7 or the ROM 6 are not corrupted by the error code, the clock unit 8 reads the present time.
Then, "minutes" or less is rounded down, and the table of the same time as the read time is searched from the time-volume information table of FIG. 2 to read the volume information to be set. Next, the volume is set in the volume control unit 1 according to the volume information read from the time versus volume table of FIG. When the volume setting is completed, the audio signal 101 is sent to the spooker 3, the image signal 102 is started to be transmitted to the display unit 4, and the television is turned on.

Next, the setting standard of the preset value which is preset in the time-volume information table will be described. As an example of the default value of the time-to-volume information table, for example, if the volume is set from 10 to 10 from "0 to 9", the volume is low until "6:00 to 7:00" when a person starts to get up. ". Breakfast and work hours "7: 00-09:
Medium volume "5" until 00 ". Large volume" 6 "during noisy hours" 9: 00-18: 00 ". Medium" 18: 00-20: 00 "for dinner Volume ”
5 ". The surroundings of the night become quiet" 20:00 to 23:00
“0” is a small “4.” It is set to “23:00 to 6:00”, which is a time zone when a person is sleeping from midnight to dawn, and “3” with a low volume.

By setting the default value of the time-to-volume information table as described above, even when the television is watched at a high volume during the day as in the past, when the television is turned on at night, it suddenly becomes large. There is no sound, and the volume is low, which is the set value of the time and volume information table.

Next, a method of setting the time-volume information table will be described.

When the key for calling the time-volume information table setting function is pressed from the input unit 9 while the power is on, that is, the received broadcast is being transferred to the screen, CP
The control signal from U5 is transmitted to the display control unit 2, the display control unit 2 stops sending the image signal being received to the display unit 4, and the image signal sent from the CPU 5 is displayed on the display unit 4.
Switch the display target to send to. At this time, the audio signal is kept in the receiving state.

Next, it is checked whether or not the time-volume information table in the RAM 7 is broken by an error code. If it is incorrect, the time-volume information table in the ROM 6 is read and edited for screen display, and the image data is displayed in the display control unit 2. To send. RA
If the time vs. volume information table of M7 is not broken, R
The time-volume information table of AM7 is read, edited for image display, and the image data is sent to the display control unit 2. The display control unit 2 outputs the image data sent from the CPU to the display unit 6, and the display unit 6 displays information on the currently set time and volume.

Next, the time is input from the input unit 9. CP
U5 displays the information input from the input unit 9 as needed by the display control unit 2
The information input from the input unit 9 is displayed on the display unit 4. When the time input is completed, the volume setting starts, and the CPU5
Sends the currently set volume information to the volume control unit 1 and sets the volume to the preset volume. Whenever the volume value currently set from the input unit 9 is changed, the volume setting display information is updated in the display control unit 2 each time, the volume setting display information is updated in the volume control unit 2 at the same time, and the volume control unit 1 is simultaneously updated. The volume information is sent and output from the set volume speaker 3.

When the setting of the time and volume information is completed, the information is written in the time-volume information table of the RAM 7, and an error code is generated and written. The CPU 5 stops sending the display data to the display control unit 2 and sends a signal to the display control unit 2 to output the received image signal 102 to the display unit 4.
