摘要

本文讨论了通过因特网和无线信道传输MPEG-4视频的相关问题。描述了MPEG-4内置的错误恢复能力,如灵活的重新同步标记、数据分区、报头保护、可逆vlc和强制帧内刷新。讨论了利用这些技术构建“智能”网络解码器的方法,并测量了解码器在各种信道误差条件下的视频质量。通过峰值信噪比测量和专家观察,比较了各种误差恢复技术的有效性和开销。还研究了前向纠错策略的使用以及数据包大小和边界对视频质量的影响。

Robust compression and transmission of MPEG-4 video
This paper discusses issues related to the delivery of MPEG-4 video over the Internet and wireless channels. MPEG-4's built-in error resilience capabilities such as flexible re-synchronization markers, data partitioning, header protection, reversible VLCs, and forced intra-frame refresh are described. Methods for using these techniques to build a “smart” network decoder are discussed, and the decoder's video quality is measured for various channel error conditions. The effectiveness and overheads of the various error resilience techniques are compared using both peak signal-to-noise ratio measurements and expert viewing. The use of forward error correcting strategies and the effects of packet sizes and boundaries on video quality are also examined.
