Abstract

본 발명은 케이블 TV방송국으로부터 인가되는 케이블선과 VCR의 사이에 케이블 박스 컨트롤러가 접속되어 있을 경우에 있어서, VCR 및 케이블 박스 컨트롤러에 수신되는 방송채널을 오토서치(automatic search)하여 수신되는 모든 방송채널을 자동으로 기억할 수 있도록 하는 케이블 박스 컨트롤러의 방송채널 자동기억장치 및 그 방법에 관한 것으로, 케이블TV방송국과 VCR의 사이에 접속연결되는 케이블 박스 컨트롤러에 VCR의 마이컴에서 발생되는 방송채널데이타를 수신하는 수신기를 구비시키고, 케이블 박스 컨트롤러에서 VCR에 인가되는 방송채널인 채널신호를 비디오회로부에서 검출하여 마이컴에서 동기신호가 존재하는 채널신호만을 메모리시키므로써 사용자가 VCR을 이용하여 오토서치를 하게 되면 케이블 박스 컨트롤러에 인가되는 케이블TV방송채널이 자동으로 바뀌어 원활하게 케이블TV방송을 시청할 수 있게 된다.According to the present invention, when a cable box controller is connected between a cable line applied from a cable TV station and a VCR, the broadcast channel received by the VCR and the cable box controller is automatically searched for all the broadcast channels received. The present invention relates to an automatic memory channel storage device of a cable box controller for automatically storing a memory device, and a method thereof, comprising: a receiver for receiving broadcast channel data generated by a microcomputer of a VCR from a cable box controller connected between a cable TV station and a VCR. In addition, the cable box controller detects a channel signal, which is a broadcasting channel applied to the VCR, in the video circuit unit, and stores only the channel signal in which the synchronization signal exists in the microcomputer. When the user performs auto search using the VCR, the cable box controller Cable TV Broadcast Channel Approved This will change automatically, allowing you to watch cable TV broadcasts smoothly.
