Abstract

본 발명은 디지탈 위성 방송 수신방식에 관한 것으로 특히, 수신된 위성방송신호 중 트랜스 포트 패킷을 디코딩 하는 과정과, 비디오나 오디오 패킷이 선택되었을 경우 ADAPTATION 필드의 존재를 검색하여 디코딩하는 과정 및 상업방송이 실려있을 때 녹음중인가를 판단하여 녹음중인 경우 녹음대기 상태로 모드를 전환하는 과정을 포함하는 것을 특징으로 하는 위성방송 녹음방법 및 그에 따른 장치를 제공하여, 종래 위성 수신기와 오디오기기의 연계동작으로 위성방송의 데이타 중 오디오 신호를 녹음하는데 있어서, 위성 방송의 상당 부분을 차지하는 상업광고 부분을 검출하여 이를 제외한 실제 필요한 정보만을 녹음할 수 있도록 한 것이다.The present invention relates to a digital satellite broadcasting reception method. In particular, a process of decoding a transport packet among received satellite broadcasting signals, a process of searching for and decoding the presence of an ADAPTATION field when a video or audio packet is selected, and commercial broadcasting In the case of recording, the satellite broadcasting recording method and a device according to the method comprising the step of switching the mode to the recording standby state when recording the recording, and accordingly, by the conventional operation of the satellite receiver and the audio device In recording the audio signal of the satellite broadcasting data, the commercial advertising portion, which makes up a large part of the satellite broadcasting, is detected so that only the necessary information can be recorded.
