Description

  The present invention relates to a remote control transmitter in an electronic apparatus.

  As terrestrial digital broadcasting starts and broadcast media increase in addition to terrestrial analog broadcasting, BS digital broadcasting, and CS digital broadcasting, remote control buttons for operating receivers increase, and operations for selecting programs have become complicated.

  Conventionally, a remote control is provided with a broadcast switching button, and a broadcast medium to be operated is selected to select a channel preset to a numeric button. For example, when selecting a BS digital channel, the user presses the number button after pressing the BS button, and when selecting a CS digital broadcast channel, the user presses the CS button and then presses the number button. This is because the current broadcast media to be operated is stored on the receiver side, and when a numeric button is pressed, a preset channel in the target broadcast media is selected.

Further, the operation button is provided with two-color illumination means, wherein one color is illuminated when the button is not operated, and the other color is illuminated when the button is operated. There was an operation button display device (see, for example, Patent Document 1).

Either one of the illumination means is blinked. For example, when the remote control transmitter 30 has selected a CS digital broadcast broadcast media program in the previous operation, this is stored, so the remote control transmitter 30 selects the CS digital broadcast. The LED 45 for illumination corresponding to the CS digital broadcast selection button 4 indicating that it is flashing is blinked, and a numeric button code for BS digital broadcast channel selection is transmitted.

  If any one of the numeric buttons 20 is pressed without pressing any of the broadcast media switching buttons 10, the last broadcast media operated is read from the EEPROM 48, and the broadcast corresponding to the broadcast media is read. The lighting LED of the media switching button is blinked, and the remote control code of the numeric button 20 corresponding to the broadcast media is transmitted.

  As described above, in this embodiment, since the remote control transmitter stores the broadcast media that was the object of the previous operation, the corresponding illumination means of the broadcast media is turned on simply by pressing the numeric button. The operator can indicate the operation target of the remote control transmitter to the operator, and the operator can be notified of the broadcast media to be operated by the remote control transmitter without requiring any extra action by the operator. This can improve the operation of the operator.
