Abstract

본 발명은 디지탈 DBS 로 수신된 방송신호를 선택적으로 저장매체로 전송하여 기록(카피)할 수 있도록된 DBS 수신기의 카피선택장치 및 방법에 관한 것으로, 이를 해결하기 위하여, 방송채널 선국명령과 카피모드 선택명령등을 인가하는 명령 인가수단과, 방송채널 선국명령 및 카피모드 선택명령에 응답하여, 선국된 방송채널의 스트림 패킷단위화된 디지탈 데이타내의 카피정보를 검색하며, 이 검색 결과를 근거로 하여 선국된 방송 채널의 카피모드에 대응하는 절환신호를 출력하는 마이크로 프로세서, 마이크로 프로세서의 카피모드 절환신호에 의거하여 MPEG2 시스템 디먹스로부터 제공되어 디지탈 데이타를 절환하는 멀티플렉서로 구성됨으로써, 수신된 방송신호를 저장매체로 카피하여 개인용 컴퓨터나 다른 디지탈 장치에서 보다 효율적으로 이 영상 및 음성 데이타를 응용할 수 있는 효과가 있다.The present invention relates to a copy selection apparatus and method of a DBS receiver capable of selectively transmitting (copying) a broadcast signal received by a digital DBS to a storage medium. Command information means for applying a selection command, and the like, in response to a broadcast channel tuning command and a copy mode selection command, copy information in the digital packet data stream stream unit of the tuned broadcast channel is retrieved. And a microprocessor for outputting a switching signal corresponding to the copy mode of the tuned broadcast channel, and a multiplexer for converting digital data provided from the MPEG2 system demux based on the copy mode switching signal of the microprocessor. Copy to a storage medium for more efficient use on a personal computer or other digital device. There is an effect that can be applied to the voice and data.
