BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic equipment, and particularly to electronic equipment intended to control and interlock the operations of other equipment using remote control means.

0002

2. Description of the Related Art Satellite broadcasting provides programs with a wider variety of content than conventional television broadcasting. You can watch this satellite broadcast on a television receiver or VTR.
A BS tuner is required for recording.

0003

[Problem to be Solved by the Invention] When recording satellite broadcasting, when using a type of VTR that does not have a built-in BS tuner, it is necessary to connect a separate BS tuner and a separate VTR, but depending on the recording mode, There was a problem in that recording was difficult, and in some cases impossible.

For example, when trying to perform time shift recording, so-called scheduled recording, by connecting a BS tuner and a VTR, if the BS tuner and VTR are compatible with each other in the scheduled recording function, scheduled recording will also be possible. It's easy to do. However, if the BS tuner and the VTR are not compatible with each other in the scheduled recording function, scheduled recording will be difficult.

[0005] In order to perform scheduled recording when there is no correspondence between the BS tuner and the VTR, the following methods can be considered, for example.

[0006] Each of the BS tuner and VTR is set so that a predetermined operation is started when power is supplied. For example, in a BS tuner, a desired channel is selected in advance, and in a VTR, a recording mode is selected in advance. Then, the timers of the BS tuner and VTR are individually set to predetermined times.

[0007] As mentioned above, in the method of setting the timers for the BS tuner and VTR individually at predetermined times, the timer connections are complicated, and each timer has an error, so it is not possible to set the timers correctly. There was a problem in that it was impossible to know whether or not scheduled recording could be performed unless you actually tried it.

[0008] Accordingly, an object of the present invention is to provide an electronic device that controls and interlocks other devices by using a commander, which is originally used to control a specific device, as a signal sending means.
