Abstract

본 발명은 디지탈 CATV전송망을 이용하여 위성방송을 수신할 수 있도록하는 디지탈 CATV전송망을 이용한 위성방송수신장치에 관한 것이다.The present invention relates to a satellite broadcasting receiving apparatus using a digital CATV transmission network to receive satellite broadcasting using a digital CATV transmission network.

본 발명은 SO에서 위송방송신호를 수신하여 이를 IRT(3)에 의해 각채널별 MPEG 트랜스포트 스크림으로 변환한 후, ATM 다중화부(4)에서 IRP(3)의 해당 채널의 MPEG 트랜스포트 스트림을 ATM신호화한 후, 다중화하여 전송함으로써 일반디지탈 CATV 가입자도 별도의 위성방송수신장치 없이도 위성방송 수신이 가능토록 한 것이다.The present invention receives the broadcast signal from the SO and converts it to the MPEG transport screen for each channel by the IRT (3), and then the ATM multiplexer (4) converts the MPEG transport stream of the corresponding channel of the IRP (3). After multiplexing and transmitting ATM signals, general digital CATV subscribers can receive satellite broadcasting without a separate satellite broadcasting receiver.
