ABSTRACT:
A system and method that selects an encoder redundancy scheme based on the projected cost of concealing the errors using an anticipated error concealment strategy. The invention provides a system for encoding a data set, comprising: a system that anticipates an error concealment strategy that will be used by a decoder in the event that the data set contains errors when received by the decoder; an analysis system that projects a cost for concealing the errors using the error concealment strategy; and a system that selects a redundancy scheme for encoding the data set based on the projected cost of concealing the errors using the error concealment strategy. Also provided is a decoder system for decoding packets of data, comprising: at least one error concealment strategy for concealing errors in an erroneously received packet of data; and a feedback system that provides feedback information regarding the error concealment strategy used by the decoder system to conceal the errors.
