The performance evaluation of video transport mechanisms becomes increasingly<br>important as encoded video accounts for growing portions of the network<br>traffic. Compared to the widely studied MPEG-4 encoded video, the<br>recently adopted H.264 video coding standards include novel mechanisms,<br>such as hierarchical B frame prediction structures and highly efficient<br>quality scalable coding, that have important implications for network<br>transport. This tutorial introduces a trace-based evaluation methodology<br>for the network transport of H.264 encoded video. We first give an<br>overview of H.264 video coding, and then present the trace structures<br>for capturing the characteristics of H.264 encoded video. We give<br>an overview of the typical video traffic and quality characteristics<br>of H.264 encoded video. Finally, we explain how to account for the<br>H.264 specific coding mechanisms, such as hierarchical B frames,<br>in networking studies.
