摘要
介绍IPTV中数据传输的关键技术——组播通信技术的原理及应用,提出一个IPTV中基于网络编码的IP组播系统。系统中节点对流经它的数据先进行网络编码,再进行转发,以提高节点实际的下载速率以及对网络资源的利用率。
Introduces the principle and application of multicast communication, which is key technology used in IPTV, proposes a IP multicast system based on network coding in IPTV. In this system, nodes execute a store-and-forward operation to the passed data,and thus improve, the effective download speed and network resource utilization.
