Abstract

본 발명은 분리형 영상정보처리 시스템에 관한 것으로, 종래에는 티브이 또는 브이씨알 등에서 방송신호의 수신 및 처리를 공유하는 장치가 없어 A/V 시스템 구현시 각 장치들을 별도 구입해야 하는 문제점이 있었다.The present invention relates to a separate type image information processing system. In the related art, there is a problem in that each device must be purchased separately when the A / V system is implemented because there is no device sharing the reception and processing of a broadcast signal in a TV or V-C.

이러한 점을 감안하여 본 발명에서는 디지탈 및 아날로그 신호를 수신 처리하는 회로를 구현하고, 외부입력을 변환시키도록 회로를 접속시켜 구성한다. 이에따라, 티브이 또는 브이씨알 등과 같은 기록재생장치에 방송신호를 수신처리하는 회로를 내장하지 않아도 됨으로 제조단가가 절감되고 A/V 시스템 구현이 간단하게 된다.In view of the above, the present invention implements a circuit for receiving and processing digital and analog signals, and connects the circuit to convert an external input. Accordingly, since a circuit for receiving and processing broadcast signals is not included in a recording / playback apparatus such as a TV or V-C, manufacturing cost is reduced and the A / V system is simplified.
