我们综述了在不可靠网络上进行实时视频传输的差错恢复技术。涵盖的主题包括对当今协议和网络环境及其特性的介绍、编码器的差错恢复工具、解码器的差错隐藏技术，以及需要编码器、解码器和网络之间协作的技术。我们综述了这些技术的一般原理以及H.263和MPEG - 4视频编码标准所采用的具体实现方式。文章的大部分内容致力于为使用运动补偿预测和变换编码的基于块的混合编码器所开发的技术。一个单独的部分涵盖了MPEG - 4中形状编码的差错恢复技术。
We review error resilience techniques for real-time video transport over unreliable networks. Topics covered include an introduction to today's protocol and network environments and their characteristics, encoder error resilience tools, decoder error concealment techniques, as well as techniques that require cooperation between encoder, decoder, and the network. We provide a review of general principles of these techniques as well as specific implementations adopted by the H.263 and MPEG-4 video coding standards. The majority of the article is devoted to the techniques developed for block-based hybrid coders using motion-compensated prediction and transform coding. A separate section covers error resilience techniques for shape coding in MPEG-4.
