摘要

IPTV多播频道切换时延是IPTV业务用户体验质量（QoE）指标的重要组成部分。分析了影响频道切换时间的诸多因素，并对一种由FCC服务器下发特制的以I帧为起始的单播节目流提升频道切换时间的方法进行了具体的理论分析和测试验证。

Abstract

Channel zapping time is a major factor in the IPTV quality of experience. The factors that impact the length of the channel zapping time were analyzed

and a unicast-based fast channel change solution was studied both theoretically and experimentally.
