Abstract

A system and method for source coding a signal to localize transmission errors to a set of samples 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 with each data set having a set of SEs. Each SE component of a data set is grouped into a plurality of divisions with each SE component having a plurality of bits. The plurality of bits of the SE components are distributed from the plurality of divisions across a generated bitstream. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.
