8-VSB LIKE BACKWARD-COMPATIBLE ROBUST STREAM MODULATION FOR ATSC DIGITAL TV TRANSMISSION

摘要

A system and method is provided for generating backward compatible robust ATSC 8-VSB bit streams for transmission by a digital transmitter (100). A backward compatible robust digital TV modulation technique is employed where a multiplexed stream (301) of bits is encoded such that the constellation (203) is similar to a standard 8-VSB constellation (200).
