Abstract

본 발명은 동시 디지털방송용 방송장치에 관한 것으로, 종래에는 위성방송으로 HD방송데이타 또는 NTSC방송데이타를 출력하면 HD방송 수싱기 HD용 위성수상기를 가진 가정에서만 시청이 가능하고, NTSC방송 송신시에는 NTSC용 위성수신기를 가진 가정에서만 시청이 가능하므로 어느 한쪽에서는 방송을 시청하고 싶어도 시청할수 없는 문제점이 있다. 따라서 본 발명은 HD영상을 위성으로 방송할 때 위성의 27MHz의 대역폭에 HD영상데이타와 HD영상을 다운 샘플링(DOWN SAMPLING)하여 NTSC급 포멧으로 변환하여 얻은 NTSC영상 데이타를 동시에 한 채널안에 방송하면HD급 수상기를 가진 가정에서는 HD화상을 볼수가 있고, NTSC급 수상기를 가진 가정에서는 NTSC급 영상을 볼수 있도록 한다.The present invention relates to a broadcasting device for simultaneous digital broadcasting, and in the related art, when HD broadcasting data or NTSC broadcasting data are output by satellite broadcasting, viewing is possible only in a home having an HD broadcasting receiver HD satellite receiver, and NTSC when transmitting NTSC broadcasting. Since viewing is possible only in homes with satellite receivers, there is a problem in that one cannot watch the broadcast. Therefore, in the present invention, when broadcasting HD video via satellite, when broadcasting NTSC video data obtained by down-sampling HD video data and HD video by converting to NTSC format in 27MHz bandwidth of satellite in one channel at the same time, HD homes can be seen in families with classifiers, and NTSC class homes can be seen in families with NTSC receivers.
