Patent ID: 7944988

Claim:
A system for multiplexed transmission of normal and robust digital video data, comprising: a multiplexer switching between normal and robust data inputs; one or more units configured to randomize, format, interleave and encode data output from the multiplexer into first encoded data packets associated with the normal data input and second encoded packets associated with the robust data input; and a post-processing unit configured to deinterleave the first and second encoded data packets produced by the one or more units, further comprising the steps of: (a) removing a trailing portion from each of said first and second encoded data packets, and (b) derandomizing a remaining portion of each of said first and second encoded data packets, wherein said step of removing the trailing portion from each of said first and second encoded data packets includes one of: removing reed-solomon parity bytes from said first encoded data packets, and removing encoded digital information bytes from said second encoded data packets, wherein said reed-solomon parity bytes are different from said encoded digital information bytes.
