Rohde & Schwarz, Samsung demonstrate Advanced-VSB

Rohde & Schwarz partnered with Samsung at NAB2006 to conduct the first public demonstrations of the emerging ATSC technology.

Advanced-VSB (A-VSB) was submitted by the proponents to the ATSC in 2005, is approved and is currently in the standardization process for consideration as an amendment to A/53.

A-VSB is focused at bringing extensibility tools to the 8-VSB physical layer to allow broadcasters new and more reliable terrestrial DTV services in the future, including Supplemental Reference Sequences (SRS) to address the problem of reliable ATSC dynamic reception.

The demonstration focused on a system with adequate equalizer training signals coupled with the latest algorithmic advances in receiver design principles to achieve new levels of performance in dynamic environments.
