Abstract

본 발명은 브이씨알에서 고주파 변조 가변채널을 자동을 세팅하는 기술에 관한 것으로, 일반적인 브이씨알에 있어서는 가변채널을 다른 용도로 이용하는 경우, 전용채널을 변경하기 위해 변조부의 가변채널을 볼륨스위치나 슬라이드스위치를 이용하여 사용되고 있지 않은 채널을 설정해야 하는데, 그 볼륨스위치나 슬라이드스위치를 이용하여 주파수를 정확하게 조정하기가 어렵고, 더욱이 일일이 수작업을 수행하는데 불편함이 있고, 시간이 많이 소요되는 등의 문제점이 있었는 바, 본 발명은 이를 해결하기 위해 팔방식의 브이씨알과 텔레비젼수상기간의 신호전송을 위해 사용되는 소정 갯수의 가변채널중에서 이미 방송채널로 사용하고 있는 채널이 있는지를 확인하여 있는 경우 마이크로컴퓨터를 이용하여 사용되고 있지 않은 가변채널을 자동으로 세팅할 수 있게 하였다.The present invention relates to a technique for automatically setting a high-frequency modulation variable channel in a V-C. In the case of a general V-C, if the variable channel is used for other purposes, the variable channel of the modulator in order to change the dedicated channel, volume switch or slide switch It is difficult to accurately adjust the frequency by using the volume switch or the slide switch, and it is inconvenient to carry out manual work by hand, and it takes a lot of time. In order to solve this problem, the present invention uses a microcomputer to check whether there is a channel that is already used as a broadcasting channel among a predetermined number of variable channels used for signal transmission between an arm type V-Cal and a television receiver. Variable channels that are not in use It was able to set in.
