摘要： According to the present invention there is provided a communication system for video data, said system comprising a "Multiple Description Coding" (MDC) system, adapted to generate, for each frame or slice of a video sequence, at least one "Primary Slice Description" (PSD) (21) and one or more "Redundant Slice Description" (RSD) (22), said system being further adapted to interlace said plurality of PSD and RSD descriptions, so as to generate a corresponding plurality of "Video Descriptions" (VDs) adapted to be transmitted to a plurality of clients and/or users of a communication network over a plurality of communication paths.
摘要翻译：根据本发明，提供了一种用于视频数据的通信系统，所述系统包括“多描述编码”（MDC）系统，适用于为视频序列的每个帧或片段生成至少一个“主要片段描述 “（PSD）（21）和一个或多个”冗余片描述“（RSD）（22），所述系统还适于交织所述多个PSD和RSD描述，以便产生相应的多个”视频描述“ （VD），适于通过多个通信路径发送到多个客户端和/或通信网络的用户。

摘要： The invention relates to a distributed arithmetic coding method of a first data source (X) having an associated entropy (H), and of at least a second data source (Y) statistically correlated to the first (X), in which to each of said sources (X, Y) is associated a respective sequence of symbols (X 0 , X 1 ,..., X N-1 ; Y 0 , Y 1 ,..., Y N-1 ), in which each symbol belongs to an M-ary alphabet, wherein M can be different for the two sources (X, Y), with associated a group of probabilities (p 1 ,..., p M ) in which the values are included within the interval from 0 to1. Said method is characterized by the fact of coding the first source (X) ambiguously with a bit rate less than its entropy (H). The invention further relates to corresponding decoding methods.
摘要翻译：本发明涉及具有相关熵（H）的第一数据源（X）和至少与第一数据源（Y）的统计相关的第二数据源（Y）的分布式算术编码方法，其中，所述源（X，Y）相关联的符号序列（X <0>，X 1，...，X N-1） ; Y 0，Y 1，...，Y N-1），其中每个符号属于M字母，其中对于两个源（X，Y），M可以是不同的，其中相关联的一组概率（p 1，...，p M M），其中值包括在从0到1的间隔内。所述方法的特征在于以比其速率小于其熵（H）的比特率来模糊第一源（X）的事实。本发明还涉及相应的解码方法。
