Abstract

This paper describes the advanced dual stream system for improving mobile/pedestrian reception performance to the ATSC DTV 8-VSB transmission standard. The proposed system can transmit a mixture of normal (8-VSB) stream and enhanced (robust) stream. The robust stream has a lower threshold of visibility (TOV) compared to the standard stream, and legacy receivers ignore the robust packets. Thus, the enhanced-xVSB system is fully backward compatible with a current ATSC standard. For more robust transmission support, E-xVSB system adopts a reduced constellation method as well as enhanced trellis-coded modulation scheme. E-xVSB system supports a variety of enhanced modulation schemes: pseudo-2VSB, enhanced-4VSB, modified enhanced-8VSB and hybrid-VSB. The proposed system has been tested in the lab, and the testing results are shown in this paper.
