摘　　要：为以更高的效率提供互动式手机电视业务,基于诺基亚的IP数据广播结构,提出了一种使用DVB-H网和蜂窝网相结合的群组式方案.该方案使用蜂窝网作为回程信道,搜集点播选择信息,将点播同一内容的若干用户划为一组,点播内容通过DVB-H网递送.仿真结果表明,相对于一对一的流媒体提供方式,该方案可获得高得多的网络容量和小得多的用户平均等待时间,并具有价格优势.In order to offer more efficient interactive mobile TV service, based on the architecture of Nokia;s IPDC, this paper presented a group-based approach with DVB-H and cellular network, which groups the subscribers by the contents they choose, and offers one channel to a certain amount of subscribers on the same content. The selection information on the contents is collected through cellular network, while the video contents are delivered from DVB-H. The simulation results demonstrate that this groupbased approach can gain much higher capacity, much lower user average waiting time, and much cheaper price, compared with the one-to-one video streaming approach.
