A Latency Analysis on H.264 Video Transmission Systems

Controlling and minimizing the delay of real-time video transmission systems is a key issue in latency sensitive applications. Examples for such kind of systems include classical video conferencing applications covered by H.263 implementations, and remote controls or RF studio cameras which require much lower delays. This document gives an overview of the delay sources in compressed video transmission systems and discusses algorithmic and buffer delay effects of different CBR compression modes.
