Ramos, Fernando M. V.
Abstract :
Zapping delay, the latency experienced by users when switching between TV channels, is one of the most severe problems affecting IPTV deployment. Synchronization and buffering of video streams can cause channel change delays of several seconds. In this article we analyze the root causes of the problem and survey some of the most relevant techniques proposed to mitigate it.
