New H.265 Video Standard to Deliver Higher Quality, More Efficient Compression

New compression standard could be in commercial products as early as next year
The Moving Picture Experts Group (MPEG) met recently to issue a draft international standard of a new video compression format offering twice the performance of current standards. The new video compression format is called High Efficiency Video Coating or HEVC. The new H.265 compression codec is roughly twice as effective as the current H.264/AVC standard.
“There’s a lot of industry interest in this because it means you can halve the bit rate and still achieve the same visual quality, or double the number of television channels with the same bandwidth, which will have an enormous impact on the industry,” says Per Fröjdh, Manager for Visual Technology at Ericsson Research, Group Function Technology, who organized the event as Chairman of the Swedish MPEG delegation.
H.265 could usher in ultra high definition television with significantly more clarity than the 1080p we have today. The new compression format will also significantly reduce the bandwidth required for streaming video on mobile networks where wireless spectrum is at a premium. The format will pave the way for wireless carriers to offer more video services within the confines of their available spectrum.
“Video accounts for the vast majority of all data sent over networks, and that proportion is increasing: by 2015, it is predicted to account for 90 percent of all network traffic,” Fröjdh says.
He believes that the HEVC format discussed during the meeting in Stockholm could find its way into commercial products as early as 2013.
“It will take time before it’s launched for a TV service, but adoption is much quicker in the mobile area, and we’ll probably see the first services for mobile use cases next year,” Fröjdh added.

While I'd love an 80" TV, 1080p is not anywhere close to sharp on a screen that big. If anything, it looks about like SDTV did on a 30" screen. My 24" monitor just slightly higher res than your 80" TV. And of course we now have the Mac book with an even higher res screen, but that's just be extravagant as I didn't see any benefit while using it on a panel that small.
I agree adoption of anything bigger like 4K would take forever, but to say there would be no benefit at screen sizes like yours isn't accurate.

I've got a 1080p projector on an 80" screen in my apartment. Your head sits about 8 feet from the screen. The resolution is more than sufficient for sharp detail. There might be a benefit to 4k video at that size/distance, but there comes a point of diminishing returns where the source material doesn't benefit.
Remember, the vast majority of movie theatres these days use 2K projectors (similar to 1080p) on ginormous screens, and nobody really notices the difference if they see something in the few theatres that use 4K projectors.

I have a 120" projection setup (DLP) and I have a 27" tube TV. The difference is significant.
1080p HD is a big improvement over SD and like the previous poster says, the sizes it enables are large enough that most users will not outgrow the options.
