Abstract

VCR의 재생 영상 신호를 TV로 수신함에 있어서, VCR을 재생 모우드로 동작시킨 후 TV의 파우어를 ‘온'시키고 TV 채널을 VCR의 RF 채널로 변환시켜야 하는 조작이 번거로운 문제점이 있다.In receiving a playback video signal of a VCR to a TV, there is a problem that it is troublesome to operate the VCR as a playback mode and to turn on the power of the TV and convert the TV channel to the RF channel of the VCR.

따라서 VCR에서는 RF채널변환을 인식하고 재생 모우드로 동작시키면 TV 파우어‘온'신호와 RF 채널변환 데이타를 VCR 외부에 설치된 리모콘 송신기를 통하여 외부로 송신시키고 TV에서는 상기 리모콘 송신기에서 송신된 리모콘 신호를 외부에 설치된 리모콘 수신기를 통하여 수신된 데이타에 따라 TV의 파우어 및 채널을 변환시키도록 하므로써 VCR을 재생시키는 동작만으로 TV의 파우어를 ‘온'시키고 VCR의 RF채널로 변환시킬수 있다.Therefore, when VCR recognizes RF channel conversion and operates as a playback mode, the TV power 'on' signal and RF channel conversion data are transmitted to the outside through a remote control transmitter installed outside the VCR, and the TV transmits the remote control signal transmitted from the remote control transmitter to the outside. By converting the power and channel of the TV according to the data received through the remote control receiver installed in the VCR, the power of the TV can be turned on and converted into the RF channel of the VCR only by playing the VCR.
