High definition TV broadcast standards need to be reviewed and improved. So says Hans Hoffman, of the European Broadcasting Union (EBU).
Speaking at the recent Society of Motion Picture and Television Engineers (SMPTE) Tech Conference and Expo, in California, he said the time was right to plan for an introduction of higher-frame rates, to better compete against Blu-ray.
Hoffman wants to see the widespread introduction of 1080p 50/60, and he’s supported by the Digital Video Broadcasting Project standards group and the Video Coding Experts Group and Moving Picture Experts Group.
Not that all HD TVs can currently display 1080p 50/60. ‘The evolution would entail an upgrade on the kind of HD sets currently being sold and the settop boxes in general distribution, as well as huge investment in compression tools and infrastructure,’ says Hoffman.
Currently only a couple of US broadcasters deliver true 1080p to their customers (DirectTV and Dish Network).
A key to the introduction of high-frame rate HDTV is the development of a new codec. Currently the most advanced in general use is MPEG-4 AVC/H.264.
The BBC has already shown technical demonstrations of higher frame-rate HD, which offers perceivable benefits in image clarity and smoothness.
