%X AVS(audio video coding standard) is a digital audio-video coding/decoding standard proposed by China since 2002.It adopted many digital audio-video codec techniques developed by Chinese companies and universities in recent years.It has lower complexity in comparison with H.264/AVC.And very low royalty fee will be charged through one-step license to use AVS including all tools.So AVS is regard as a good and competitive candidate for Chinese satellite TV signal directly to home(DTH).In this paper,the difference of AVS and MPEG-2 is studied.We also analyze alternative approaches,such as direct AVS codec and AVS transcoder,to transmit video stream via satellite,and discuss the design of corresponding transcoding scheme.At last a realization of new generation satellite system with AVS is presented.
