8 is a TV remote control transmitter m, 1 s a is a remote control light receiving section of the converter 19, and 19b is a memory.

Summary of the above First, the TV remote control transmitter 2
8 is pressed, the remote control light receiving section 19a of the converter 19 receives the data, converts it into an electrical signal, encodes it in the control section 21, and stores the received data in the memory 19b. Data from the television remote control 28 for the volume increase button, volume decrease, audio mute, and audio switching are received by the remote control light receiving section 19a and similarly stored in the memory 19b as a remote control code. On the other hand, special buttons 1 on the converter's remote control 2o indicate volume increase, K2
corresponds to the function of decreasing the volume, K3 corresponds to the sound mute, and K4 corresponds to the function of changing the sound.When you press the special code button 1 to 4 on the converter remote control 20, the optical remote control signal corresponding to that button is sent and received. The transmission control unit 23 generates an optical remote control code corresponding to each special button stored in the memory by the converter 19 that has been converted, and controls the television remote control light emitting unit 26 via the remote control control line 24 to control the state of the television 26. be able to. It was,
At the same time, the converter 19 is turned on/off using the tt power on/off button on the converter remote control 20, and the remote control signal for turning on/off the television 26 is turned on/off.
By sending the signal to the V-remote control light emitting unit 25, it is possible to control whether the TV power is turned on or off.

As a result, the original TV remote control transmitter is only needed when registering data, and the rest can be operated with a single remote control, so you can turn the TV's power on and off by turning the converter's power on and off. This has the advantage of reducing the number of remote control button operations and improving usability.

Furthermore, the aforementioned audio mute signal is outputted to the television 26 when the converter 19 switches channels, and after the channel switching and the channel selection operation of the converter 19 becomes stable, the mute state on the television 26 side is canceled by the audio mute signal again. This makes it possible to eliminate unpleasant noises during channel switching, which could not be eliminated by conventional RF converters. Also, volume control using the RF converter.

is a remote control transmitter for television.

Since the video signal output from the baseband converter and input to the television is a baseband video signal, it is necessary to set the operation mode of the television to video mode. With today's TVs, if you turn the power off once, many TVs start up in TV mode when you turn them back on, so you don't have to worry about changing to video mode using the remote control or panel button. There are some drawbacks. Therefore, in this embodiment, a remote control signal generated by operating the "TV/Video" switching button of the TV remote control transmitter 39 can be stored in the memory section 33 of the converter 30, and this switching operation can be performed using the remote control 29 for the CATV converter. A special button is provided to enable execution. With this configuration, when the converter 30 is turned on with the converter remote control 29, the converter 30 transmits a power-on remote control signal to the television 37, and the television 37 is turned on.
At the same time, a remote control code for "video/television" switching is sent to the television 37, and the television 37 enters the video mode. By doing so, it is possible to receive the video signal output from the converter on the television side.

The advantage of this embodiment is that you can turn on the TV and switch the TV status to video mode with a single remote control operation that turns on the converter. You only need to use it, and no further operations are required.

In the above embodiment, the transmitting means of the optical remote control was composed of a control line and a light emitting part placed near the TV remote control light receiving part. You can also use the method of leading in a club. or
