Axcera Partners with NAB-HD to Provide Transmitter System for Digital Television Station Demo at NAB 2005

Distributed Transmission Technology Leader Discusses ATSC Enhancements

APRIL 12, 2005, LAWRENCE, PENNYSLVANIA, U.S.A. - Axcera, a leading manufacturer and integrator of best-of-breed technology for the television broadcast and broadband wireless access industries, and the industry leader in Distributed Transmission (DTx) technology, today announced that it will present an engineering paper discussing the new technology developments resulting from the field deployment of DTx and how these developments have enhanced ATSC Standard A/110 for DTx transmitter systems and may also improve single transmitter systems.

Axcera’s paper will discuss the symbiotic relationship between the development of DTx technology and the resulting improvements to the ATSC DTV system. Topics covered will include: elimination of the effects of STL timing variations for DTx systems through synchronization of the SMPTE 310 bitstream to GPS; techniques for GPS locking; advantages of GPS locking in both DTx and non-DTx applications; field experience; and other topics, including enhanced VSB (E-VSB) and DTV Watermark.

The paper will be presented by Axcera Principal Engineer, David Hershberger, on Thursday, April 21st at 10:00 a.m. during the Distributed Transmission session of the NAB Broadcast Engineering Conference in Las Vegas, NV.
