摘　　要：提出一种S-DMB系统的自适应接收(AR)方案。利用可分级的视频编码技术获得分层的数据流,并通过广播信道分级传输视频信息。按照终端设备的类型,在接收端通过一个帧选择控制器自适应接收最少帧数据。通过对S-DMB手机的功率消耗和实际的可视时间定量分析,证实了AR方案的优势。An Adaptive Reception （AR） scheme for S-DMB system is proposed. The hierarchic data stream is obtained by adopting Scalahle Video Coding （SVC） technique, and the video information is hierarchically transmitted through the broadcasting channel. According to the type of terminal equipment, the data frames with least amount are adaptively received by a frame selection controller at the receiving end. By way of the quantitative analysis of power consumption and available viewing time in S-DMB mobile phones, the advantages of AR scheme is proved.
