Patent ID: 8194750

Claim:
A system for processing high definition video data to be transmitted over a wireless medium, the system comprising: a plurality of convolutional encoders configured to input a plurality of video data streams and output a plurality of encoded data streams, respectively, wherein each data stream includes a plurality of data bits; a group multiplexer configured to multiplex the plurality of encoded data streams into a multiplexed data stream based on a first multiplexor group size for a first portion of the plurality of encoded data streams and a second multiplexor group size for a second portion of the plurality of encoded data streams, wherein the group multiplexer is further configured to multiplex a plurality of data bits together at one time; a circulant bit interleaver configured to receive an m×n data stream block having n columns and m rows or convert the multiplexed data stream to an m×n data stream block, wherein the m×n data stream block comprises m×n data bits, and wherein the bit interleaver is further configured to interleave the received data bits diagonally and in a circulant manner with respect to the m×n block; and a quadrature amplitude modulation (QAM) mapper configured to perform QAM mapping for the interleaved data.
