[0002]

2. Description of the Related Art In recent years, television receivers capable of receiving satellite broadcasts in addition to general television broadcasts such as VHF and UHF have been proposed.

[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]

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

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

In the case where a plurality of remote controllers having different operation methods of the buttons are attached as described above, for example, the user actually selects one of the favorite remote controllers and discards the other remote controllers, or hands. Unless it is out of reach, there will always be a plurality of remote controllers around the location where the television receiver is installed.

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

Further, it is conceivable that the user always places all 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, for example, When the setting operation is performed on the screen using the remote controller, the (+) button or the (-) button is pressed, and when performing the same setting operation using another remote controller, the operation method is different, such as rotating the button. However, there is an inconvenience that the operation method of the remote controller that the user is currently using cannot be understood.

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

However, the button and the operation method of the button of the other remote controller are different from the button and the operation method of the button of the one remote controller. When the operation method is displayed on the screen, the operation method of the remote controller currently used is increasingly unknown, and there is a problem that the user is confused.

The present invention has been made in view of the above point. For example, even when a plurality of remote controllers having different operation methods of operation buttons are used for the same device, the currently used remote controller is used. Is a television receiver that can be recognized on a screen and can easily determine which button of the remote controller should be operated when a desired operation is to be performed with a currently used remote controller. It is something to propose.
