A method for source coding a signal is described. In particular, a signal comprising multiple signal elements is processed. Each signal element is encoded to form a bitstream. The bits within a given bitstream are distributed across different bitstreams. Thus, the parameters describing components of the segment elements are distributed across the different bitstreams. The grouping and distributing steps result in error distribution across multiple levels of image reconstruction. Another method is also described for a multiple level shuffling process. A signal is defined as multiple levels wherein each level comprises a frame, a plurality of pixels, and a plurality of bits. In one embodiment, shuffling occurs on each level and between levels. Multiple level shuffling causes burst error loss to be distributed across multiple levels thereby facilitating image reconstruction of those areas of the image in which the loss occurred.
