April 16, 2007 (Press Release) --
Samsung announced at NAB 2006 a new innovative technology that enables portable and mobile TV digital broadcasting in North America at very low cost, using broadcasters’ existing facilities and frequency spectrum. 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.
Advanced-VSB (A-VSB) is a proposed open standard that broadcasters can implement at low cost, providing an all-new distribution channel through which broadcasters can reach consumers with live TV on the go via portable media devices, whether traveling by car or bus or walking down the street.
For the duration of NAB, live A-VSB transmissions will be 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. The same programming will also be re-transmitted at a second frequency on a separate low-power SFN. The SFN is being set up with the support of ION Media Networks (which previously has conducted limited testing of A-VSB in Tampa, Florida) and will be operated under an experimental license to ION from the Federal Communications Commission. The SFN will have three transmitter sites, two located on structures north and south of the Convention Center along the Las Vegas Strip and one inside the Convention Center at the ATSC Digital TV Hot Spot. The SFN demonstration will show how A-VSB makes it easy for broadcasters to maintain complete signal coverage and transmission, filling in gaps between buildings and behind mountains for maximum service quality.
Together, Samsung Electronics and Rohde & Schwarz have developed A-VSB as a dramatic enhancement to the Advanced Television Systems Committee (ATSC) digital TV transmission standard.
The technology is being standardized in ATSC, and an ATSC-supervised lab test was conducted in November 2006, with field tests to be mounted in the first half of 2007. A completed standard is targeted for 2007, with implementation by broadcasters and consumer electronics manufacturers beginning soon afterward, aiming toward widespread commercial services before the February 2009 transition to all-digital TV broadcasting in the United States.
For the first time at NAB 2007, Samsung will demonstrate a "half-rate Turbo" mobile reception mode using half the bandwidth of the previously demonstrated "quarter-rate Turbo" mode. Half-rate mode is targeted for highway speeds, rather than the faster bullet train speeds which quarter-rate mode enables.
