This week, Thomson Video Networks is conducting France's first demonstration of high-quality video broadcast of five HD channels in a DTTV 24.8Mbps multiplex, enabled by the company's ViBE EM4000 HD/SD encoder and NetProcessor multiplexer/video processor. The demonstration, which began on 30 November and will continue through until tomorrow, is being managed by the HD Forum at the NRJ main broadcasting facility in Paris.
Thomson Video Networks created the demonstration to show how advanced compression technology can be used to broadcast five HD channels, instead of the three currently used today in France, in a DTTV 24.8Mbps multiplex without compromising video quality. With 1080ix1920 HD content provided by five French broadcasters, Arte, Canal+, France Televisions, NRJ, and TF1, the ViBE EM4000 encodes the video in MPEG-4 VBR (statistical multiplexing). The HD content is then multiplexed by the NetProcessor, modulated in DVB-T, and displayed on five 46-inch and 55-inch televisions with built-in decoder capabilities.
"Worldwide, broadcasters on DTTV platforms are looking for the best picture quality at the lowest possible bandwidth,” said Claude Perron, chief technology officer at Thomson Video Networks. In this demonstration, we're showing how dramatic advancements in compression technology are providing a migration path to HD and offering a better experience for viewers. Although we're focusing on the French DTTV platform here, the technology can be applied to any DTTV platform using the EM4000 and NetProcessor."
