Abstract

본 발명의 다채널 디지탈 위성방송수신기는 사용자의 선택에 의한 각 티브이의 제어신호에 따라 해당채널을 선국하기 위한 제1디코더부와, 상기 제1디코더부에서 선국된 채널 데이터를 해당 티브이에 선택적으로 전송하기 위한 출력선택부와,상기 각 티브이별 선국 채널 데이터를 전송받아 티브이에서 사용할 수 있는 영상 및 음성신호로 변환하기 위한 제2디코더부로 구성되며, 회로의 중복을 방지할 수 있으며, 채널선택부를 통해 각 티브이별로 선택된 채널데이타가 출력되도록 연결함으로써 티브이별로 개별적인 선택이 가능하다.The multi-channel digital satellite broadcasting receiver of the present invention selectively selects a first decoder unit for tuning a corresponding channel according to a control signal of each TV according to a user's selection, and channel data tuned by the first decoder unit to the corresponding TV. And an output selector for transmitting, and a second decoder for receiving the tuned channel data for each TV and converting the video and audio signals to be used in the TV, and prevents duplication of circuits. By connecting the selected channel data for each TV through the TV, the TV can be individually selected.
