GENEVA, Jan. 7 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM - News), the world's leading supplier of set-top box (STB) chips, has announced that it successfully operated a live 8PSK turbo-coded satellite digital TV broadcast during a satellite test in "France Telecom Reseaux et Services Internationaux" premises in Rambouillet, France. The demonstration, which took place on December 5, 2002, was based on ST's STV0499 8PSK Turbo Coding technology, which increases throughput for advanced satellite broadcast services up to 50% over today's commercial satellite links.
The demonstration, which featured an actual satellite connection, highlights STMicroelectronics' collaboration with French satellite pay-TV operator TPS and Eutelsat, which provided the satellite link (EUROBIRD 2 / 33 degrees E on a 16.8 MHz bandwidth, using 1/2 transponder). Although developed for data rates up to 45Mbaud, the STV0499 used in the demonstration system ran downstream at 12.2Mbauds (useful bit rate of 25.2 Mbps) input. The system that has been demonstrated provides satellite broadcasters with an efficient method of increasing throughput over existing satellite infrastructures and providing new services for their customers.
Addressing all digital satellite TV markets, the STV0499 allows broadcasters to obtain increased bandwidth through their existing transponders, thereby allowing them to offer additional services (such as additional standard TV channels, HDTV or Internet download) or to reduce the dish size by more than 33% with their existing satellite slots.
"Satellite broadcasters require higher throughput to offer HDTV and other bandwidth-intensive services," said Christos Lagomichos, Vice-President of ST's Set Top Box division. "With this device, we are providing broadcasters with a risk-free path to take digital satellite TV into its next stage."
