Abstract
본 발명은 유선방송(케이블 티브이)수신 기능을 갖는 브이시알 시스템에 관련된 것으로서, 종래에는 이러한 시스템에서 유선방송 신호를 입력받기 위하여는 케이블 티브이 방송의 공급자가 제공하는 영상 신호속에 스크램블링 신호가 있어 이를 수신측에서 해독하는 디스클램블링 기능을 갖는 디코더로 수신하지 않으면 아니되었기 때문에 이러한 시스템의 번거로움을 피하기 어려운 것이었다.The present invention relates to a VSI system having a cable broadcasting (CTV) reception function. In order to receive a cable broadcasting signal in such a system, a scrambling signal is received in a video signal provided by a provider of a cable TV. It was difficult to avoid the hassle of such a system because it had to be received by a decoder having a descrambling function for decoding on the side.
본 발명은 종래의 이러한 문제점을 개선할 수 있도록 시스템의 영상 및 음성신호 출력부(13)와 라인 입력단(L1), 케이블 티브이 케이블(CAC)과 연결된 케이블 티브이 디코더(14)등의 오디오/비디오(A/V) 신호원을 선택하여 시스템으로 제공하는 주 스위치부(13)와, 이 주 스위치부(13)의 입력으로 연결되어져 있는 케이블 티브이 디코더(14)와, 시스템 마이크로 프로세서(11)와, 이 마이크로 프로세서(11)와 주 스위치부(13) 사이에 연결되어져 있는 비밀번호 비교부(12)로 이뤄져 있는 브이시알의 유선방송 입력처리 시스템을 제공하는데 있다.The present invention provides a video / audio signal output unit 13, a line input terminal L1, and a cable TV decoder 14 connected to a cable TV cable (CAC). A / V) a main switch unit 13 which selects and provides a signal source to the system, a cable TV decoder 14 connected to an input of the main switch unit 13, a system microprocessor 11, The present invention provides a broadcast broadcasting input processing system of VSI, which is composed of a password comparison unit 12 connected between the microprocessor 11 and the main switch unit 13.
