FLEXIBLE REDUNDANCY CODING

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 (310). A set of the 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 (320). 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.
