Abstract

A method and system are described for a multiple level shuffling process of a signal that provides for robust error recovery. 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.

91. The computer readable medium as set forth in claim 90, further comprising instructions, which when executed, further cause the system to:

deshuffling said SE components among said set of said plurality of segments using a plurality of predetermined deshuffling patterns, wherein said deshuffling returns said SE components to a location prior to said shuffling;

decoding said encoded SEs; and

remapping said plurality of SE components of said plurality of segments to said data set, wherein said remapping returns said SEs of said plurality of segments to a location prior to said mapping.

92. The computer readable medium as set forth in claim 90, wherein said SE components comprise fixed length data.

93. The computer readable medium as set forth in claim 90, further comprising instructions, which when executed, further cause the system to:

group encoded SEs within each said set of segments into a plurality of SE groups; and

shuffle SE components between SE groups of said set of segments using at least one of said plurality of pre-determined shuffling patterns.

94. The computer readable medium as set forth in claim 93, further comprising instructions, which when executed, further cause the system to repeat the shuffling of SE components between SE groups until every SE group of said set of segments is shuffled.

95. An apparatus for shuffling signal element (SE) components of a signal comprising:

means for mapping a data set into a plurality of segments, said data set having a plurality of SEs, each SE including a plurality of SE components;

means for encoding said SEs; and

means for shuffling said SE components among a set of said plurality of segments using a plurality of predetermined shuffling patterns.

96. The apparatus as set forth in claim 95, further comprising:

means for grouping encoded SEs within each said set of segments into a plurality of SE groups; and

means for shuffling SE components between SE groups of said set of segments using at least one of said plurality of pre-determined shuffling patterns.

97. The apparatus as set forth in claim 96, further comprising:

means for repeating the shuffling of SE components between SE groups until every SE group of said set of segments is shuffled.
