Abstract

본 발명은 디지탈위성 영상수신기(DSVR:digital Satellite Video Receiver)에 있어서, 특정채널의 특정프로그램을 지정하면, 다른채널의 프로그램을 시청하는 도중 지정된 프로그램이 시작되면 자동으로 상기 지정된 채널로 복귀하는 자동 채널복귀 기능을 구비한 디지탈위성 영상수신기에 관한 것으로, 위성으로 송출되는 트랜스포트스트림에 포함되는 프로그램지정정보(PSI) 패킷에 들어있는 사건정보테이블(EIT)을 이용하여, 예약된 프로그램의 정확한 방영시각 및 채널등과 같은 사건정보를 추출하고, 그 정보에 따라서, 정확한 시각에 예약된 프로그램을 자동 출력하도록 구비한다.According to the present invention, when a specific program of a specific channel is designated in a digital satellite video receiver (DSVR), an automatic channel automatically returns to the designated channel when a specified program is started while watching a program of another channel. The present invention relates to a digital satellite image receiver having a return function. An accurate broadcasting time of a reserved program is recorded by using an event information table (EIT) contained in a program specific information (PSI) packet included in a transport stream transmitted to a satellite. And extracts event information such as a channel and the like, and automatically outputs the reserved program at the correct time according to the information.
