摘　　要：从视音频编码角度出发,对提高T-DMB系统视音频播放质量的一些容错技术进行了总结归纳。介绍了T-DMB标准视音频编码的基本原理,讨论了T-DMB系统固有的容错特性,对基于解码端容错工具的错误隐藏技术进行了总结。In this paper, some error-resilient techniques that can be used to improve the playing quality of T-DMB system are surveyed from the view of video and audio coding. The basic principle of video and audio coding standard in T-DMB system are introduced, then the error-resilient features of T-DMB system are discussed, and a number of error-concealment techniques that can be put into use in the decoder side are also presented.
