When the main power source is turned on, power is supplied to the tuner for general television broadcasting and the satellite broadcasting receiving section respectively, and these perform reception and output operations.
When the main power supply 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 reserved program at a desired reserved time, color adjustment, volume adjustment, etc. It can be set.

A desired item among these items is displayed on the screen, for example, and parameters of the displayed item can be set.

[0008]

By the way, in a television receiver having many setting items as described above and which can be set by a remote controller, in order to meet various preferences of the user. In addition, it has been considered to attach a plurality of remote controllers having different button operating methods to a television receiver.

For example, as an example of the case where two remote controllers are attached, one remote controller is operated by the (+) button and the (-) button at the time of selection operation on the screen, and the other remote controller is operated by, for example, It is conceivable to rotate the button to operate the selection operation on the screen.

When a plurality of remote controllers having different button operating methods are attached as described above, for example, the user actually selects one of the remote controllers he / she prefers, discards the other remote controller, or hands. Unless it is out of reach, there are always a plurality of remote controllers around the place where the television receiver is installed.

Further, even when there are a plurality of users, if the remote controllers to be used are different from each other, a plurality of remote controllers are always provided around the place where the television receiver is installed as described above. Will exist.

Further, it is possible that the user always puts all the attached remote controllers around the television receiver and uses a different remote controller each time.

In any case, when a plurality of remote controllers are placed around the place where the television receiver is installed and all of the plurality of remote controllers are used in this way, for example, When performing the setting work on the screen using the remote controller, the (+) button or (-) button is pressed, and when performing the same setting work using another remote controller, the operation method such as rotating the button is different. , There was an inconvenience that I could not understand the operation method of the remote controller I am currently using.

As a solution to this, for example, it is possible to display on the screen the shape of the button of one remote controller and the operation method.

However, the button of the other remote controller is different in shape and operating method from the button of the one remote controller. Therefore, when the other remote controller is used, the button shape and the button of the one remote controller are different. When the operation method is displayed on the screen, the operation method of the remote controller currently in use is more and more unknown, and there is an inconvenience that the user is confused.

The present invention has been made in view of the above points. For example, even when a plurality of remote controllers having different operation methods of operation buttons are used for the same device, the remote controller currently used is used. On the screen, and when you want to perform a desired operation with the remote controller you are currently using, you can easily determine which button on this remote controller should be operated. It is a proposal.
