摘要： Various disclosed implementations allow a flexible amount of redundancy to be used in coding. In one general implementation, information is accessed for determining which of multiple encodings of at least a portion of a data object to send over a channel. A set of multiple encodings is determined for sending over the channel, with the set including at least one and possibly more of the multiple encodings, and the number of encodings in the set being based on the accessed information. In a more particular implementation, the redundant slice feature of the H.264/AVC coding standard is used, and a variable number of redundant slices is transmitted for any given picture based on current channel conditions.
摘要翻译：各种公开的实现允许在编码中使用灵活的冗余量。在一个一般实现中，访问信息以确定通过信道发送的数据对象的至少一部分的多个编码中的哪一个。确定一组多个编码以通过信道发送，其中该集合包括多个编码中的至少一个并且可能更多的编码，并且该集合中的编码数量基于所访问的信息。在更具体的实现中，使用H.264 / AVC编码标准的冗余片段特征，并且基于当前信道条件为任何给定图像发送可变数量的冗余片段。

摘要： There are provided methods and apparatus for block-based error concealment. An apparatus includes an error concealment module for concealing a current block in a lost picture in a group of pictures by using a last available inter-coded picture in a previous group of pictures, when the lost picture is a first inter-coded picture in the group of pictures. The group of pictures has a pattern characterized as an intra-coded picture followed by a sequence of inter-coded pictures.

摘要： There are provided method and apparatus for detecting and concealing reference and non-reference video frames. A video decoder includes an entropy decoder, an error detector, and an error concealer. The entropy decoder is for decompressing a video bitstream intended to have a fixed frame rate and parsing the decompressed video bitstream to find picture order counts for frames of the decompressed video bitstream. The error detector is for determining that a particular frame of the decompressed video bitstream is missing based upon the picture order counts. The error concealer is for concealing the particular frame. The method is accomplished by decompressing and parsing the video bitstream to find picture order counts for frames of the decompressed video bitstream and then determining that a particular frame of the decompressed video bitstream is missing based upon comparison of their associated picture order counts, and then concealing that particular frame.

摘要： There are provided a method and apparatus for block-based error concealment. The apparatus includes an error concealment module for concealing a current block in a lost picture of a video sequence by projecting positions of at least one block in a correctly received picture of the video sequence to a position of the current block in the lost picture using motion vectors of the at least one block in the correctly received picture so as to obtain a resultant projection, and selecting one of the at least one block in the correctly received picture based upon an amount of overlap in the resultant projection. The current block in the lost picture is then concealed using a motion vector of the selected one of the at least one block in the correctly received picture.
