支持H.264视频跟踪的视频传输评价 Video Transport Evaluation with H.264 Video Traces

Abstract

论文介绍了一种基于H.264编码视频的网络传输跟踪评价方法。首先概述H.264视频编码；然后介绍了捕捉H.264编码视频特点的跟踪结构，给出一种典型的视频流量和H.264编码视频的质量特征；最后，解释了H.264特定编码机制，如分层B帧。 This tutorial introduces a trace-based evaluation methodology for the network transport of H.264 encoded video. We first give an overview of H.264 video coding, and then present the trace structures for capturing the characteristics of H.264 encoded video. We give an overview of the typical video traffic and quality characteristics of H.264 encoded video. Finally, we explain how to account for the H.264 specific coding mechanisms, such as hierarchical B frames.
