ATSC 2.0 Promises to Deliver Multitude of New Services, Including 3D, 1080/60p, and ITV 
February 18th, 2009
Next-generation ATSC over-the-air transmission standards, aka ATSC 2.0, made its most public debut to date today at HPA as Graham Jones of NAB discussed new services that could be in homes by 2012.
"It's a complete suite of next-generation services and new features designed to transition to a new class of DTV receiver," said Jones. "But it needs the buy in from broadcasters, CE makers with compelling products, retailers to sell it and communicate what it means to consumers and then consumers to find it highly desirable and easy to understand."
That could be a challenge given that the suite has 26 proposed features ranging from 1080p/60, 3D, advanced audio codecs, upconversion to 1080p, and more.
For now the ATSC has focused on three bundles of services: interactive television, 3D, and non-realtime services.
"A single set of 26 features was not realistic," adds Jones. "This is the first time we've talked about this outside of ATSC membership and we're looking for input."

It's Official: MPEG-4 h.264 Has Arrived
February 18th, 2009

The EBU demonstrated the quality of MPEG-4 h.264 at HPA
The EBU's Hans Hoffman reported at HPA today that EBU tests have found that MPEG-4 h.264 encoders have finally reached a level of performance that delivers on the promise of 50% bandwidth savings vs. MPEG-2. The EBU tested encoders from Ateme, Harmonic, Tandberg, Thomson, and Scientific-Atlanta.
"All of them performed very well and the 50% gain has been reached," said Hoffman. "With some content it is even better than 50%."
In terms of bandwidth needed for "critical material but not unduly so" performance recommendations are: 10.5 Mbps for 720p/50; 12.1 Mbps for 440?1080i/25; and 12.8 Mbps for 1920?1080p/25.
