[0003] Such a television receiver has a satellite broadcast receiving unit for receiving satellite broadcasts, in addition to a general television broadcast tuner.

In such a television receiver, after a mechanical switch is turned on (called a standby state or the like), for example, a main power supply can be turned on or off by a remote controller or the like. .

When the main power supply is turned on, power is supplied to a general television broadcast tuner and a satellite broadcast receiving unit, respectively, which perform reception and output operations.
When the main power is turned off, the power supply to the general television broadcast tuner and the satellite broadcast receiving unit is stopped, and the reception and output operations thereof are stopped.

Further, in this television receiver, a remote controller or the like is operated to receive a desired reservation program at a desired reservation time, adjust colors, adjust volume, etc. The settings can be made.

[0007] A desired item of these items is projected on, for example, a display screen, and parameters and the like of the projected item can be set.

[0008]

At present, satellite broadcasting is carried out by NHK (Japan Broadcasting Corporation) on the so-called channel broadcasts 7 and 11, as well as by Japan Satellite Broadcasting Co., Ltd.
There is a private broadcast of the so-called channel 3 of SB).

[0009] The general name of this private broadcast is "WOWOW".
It is.

In addition to the private broadcast "WOWOW", broadcasting of only an audio signal having a general name of "St. GIGA" is performed by Japan Digital Audio Broadcasting Co., Ltd., under the same channel name 3.

[0011] In satellite broadcasting by these private companies, a signal obtained by scrambling a video signal or an audio signal is received by a BS antenna in a system called a scramble system.

In order to enjoy satellite broadcasting by this private company, a contract is made with the above-mentioned company, and the video and audio signals scrambled by the above-mentioned scramble decoder designated by the company are converted into the original video and audio signals, and this conversion is performed. Video and audio signals must be supplied to the television receiver.

Now, in a television receiver having a large number of setting items as described above, in order to be able to cope with such a private broadcast, when receiving "WOWOW" of the satellite broadcast channel 3, and when receiving the satellite broadcast, It has been considered to provide a selection button or the like for selecting either one of the broadcasts when receiving “St. GIGA” of channel 3.

However, in this case, first, the satellite broadcast channel 3 is designated by pressing a button on the operation panel, the remote controller, or the like.
The user has to press a selection button for selecting one of the two broadcasts, which causes inconvenience to the user.

On the other hand, in addition to the above-mentioned three satellite broadcasts, a so-called CS (satellite communication) broadcast has been started.

In the CS satellite communication, a program / information communication service is provided by using a repeater of a communication satellite launched by a private company.

The communication satellite used for the CS satellite communication has 80 repeaters, and a multi-channel pay communication service using a part of the repeater is provided by CATV stations, accommodation facilities, and joint reception facilities nationwide. Has already been done.

It is conceived that a broadcast of a certain channel is selected and the channel number is displayed on the surface of a color picture tube.

The setting of the channel number to be projected is as follows:
For example, every time the addition button is pressed, 1, 2,... BS1, B
It is conceivable that a number is projected on the screen like S2,... CS1, CS2,... CS15, and the projected number can be set by, for example, an enter button. ing.

As described above, general television broadcasts have already been called UHF and VHF as channel names of 1-6.
No. 2 is assigned, and BS1 to B in satellite broadcasting
Numbers up to S15 are assigned.
Numbers from S1 to CS30 are assigned.

Therefore, as described above, when a channel number for channel selection and a channel number projected at that time are previously set to an arbitrary button, for example, a satellite broadcast channel is assigned to a certain button. In such a case, the number to be displayed on the screen is CS1 or the like, and the number of the CS satellite communication is erroneously set. For example, the channel name of the selected broadcasting station is displayed on the screen at that time. The inconvenience of erroneously setting the channel common name occurs.

The present invention has been made in view of the above points, and can be performed with only one button operation at the time of selecting a program, thereby improving the usability and preventing a setting error. It is intended to propose a John receiver.
