METHOD AND APPARATUS FOR SOURCE CODING A SIGNAL, METHOD AND APPARATUS FOR RECOVERING A SOURCE CODED SIGNAL, AND METHOD AND APPARATUS FOR SHUFFLING SIGNAL ELEMENTS COMPONENTS TO PROVIDE FOR ROBUST ERROR RECOVERY DURING TRANSMISSION LOSSES

摘要

A system and method for source coding and decoding a signal to provide for a robust error recovery is disclosed. The signal comprises a plurality of signal elements (SEs) with each SE having a plurality of components. The signal is divided into a plurality of data sets, each data set having a set of SEs. SEs of a data set are allocated to a plurality of segments. Components of the allocated SEs are distributed across the plurality of segments. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.
