摘要
文章详细介绍了基于IP网络视频点播服务的数据传输控制策略,包括推拉结合式流量控制方法和基于丢包重传的差错控制方法,同时给出了实现该策略的视频服务器与客户端的软件结构。实验表明,该传输控制方法对VBR和CBR节目流都是有效的,能够较好地控制客户端数据量和降低数据丢失率。
The paper depicts transport control scheme of VoD service based on the IP networks in detail,including pull-push flow control method and error control method.Software architecture of VoD server and client utilizing the proposed scheme is developed in this paper.The result of experiment shows that the transport control scheme is effective for VBR and CBR stream to control amount of data in client buffer and decrease lost rate of data.
