SYSTEM AND METHOD FOR PROCESSING WIRELESS HIGH DEFINITION VIDEO DATA USING A SHORTENED LAST CODEWORD

摘要

A method and system for processing high definition video data to be transmitted over a wireless medium is disclosed. In one embodiment, the method includes 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. 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. The method further includes i) 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 ii) adding dummy bits to the outer encoded data so as to meet a predefined size requirement for an outer interleaver.
