Patent ID: 7688908

Claim:
A method of processing high definition video data to be transmitted over a wireless medium, the method comprising: receiving an information packet having the length of L bytes, wherein L=(M×n×K)+A, and where: M is the depth of an interleaver, n is the number of interleavers, K is an encoding code length and A is the number of remainder bytes with respect to M×n×K bytes, wherein the remainder bytes are located at the end of the information packet, wherein M×n×K bytes represent M×n codewords, wherein the remainder bytes sequentially form a plurality of remainder codewords, and wherein the plurality of remainder codewords comprise a last codeword which is located at the end of the remainder codewords; outer encoding the M×n codewords and the plurality of remainder codewords based on the code length (K); shortening the last codeword such that the resultant shortened codeword is shorter in length than each of the remaining codewords of the information packet; and adding dummy bits to the outer encoded data so as to meet a predefined size requirement for an outer interleaver.
