LAS VEGAS -- The A-VSB Initiative, whose members include Samsung Electronics, MobiTV, Nokia Siemens Networks, Rohde & Schwarz and SES AMERICOM's IP-PRIME[R], announced a live demonstration of an end-to-end broadcast mobile TV platform at NAB.
A-VSB is a proposed open-standard and backward-compatible enhancement of the existing U.
Since proposing A-VSB to the ATSC in 2005, we have never wavered in our commitment to set an open standard for the benefit of broadcasters, manufacturers, and consumers.
MobiTV: "We see A-VSB as complementary, not competitive, to wireless services," said Alan Moskowitz, director of strategic alliances for MobiTV, Inc.
Senior executives of these companies will announce and answer questions about a new collaboration related to mobile TV services in the United States utilizing local broadcast TV spectrum and Samsung's A-VSB mobile broadcast TV technology.
Samsung demonstrated live real-time broadcasting to a handheld device for the first time last year at CES 2007 and is demonstrating improved A-VSB performance at CES 2008.
When A-VSB becomes available in 2009, consumers will be able to receive services and entertainment from their local TV stations ranging from weather and traffic to live sports and children's programming on their mobile phones, PCs, portable media players and car entertainment systems.
Broadcasters' requirements are clear, and Samsung and Rohde & Schwarz are confident A-VSB is the only system to meet the broadcasters' requirements.
For the duration of NAB, live A-VSB transmissions were sent from local Sinclair Broadcast Group TV station KVMY Las Vegas to mobile receivers operating on a chartered bus in the Convention Center area, using the station's current transmitter and frequency.
At NAB 2007, Samsung will not only demonstrate an A-VSB mode with twice the efficiency (using half the broadcasting bandwidth) compared to Samsung's previous demonstration in January, but will also demonstrate the power of A-VSB's Single Frequency Network (SFN) tool for the first time.

A-VSB is a technology proposed to ATSC (the Advanced Television Systems Committee which approves broadcast standards) that improves current TV signal reception performance and also allows the broadcast signal to be clearly received by both mobile and stationary television devices.
