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.

It also means you need more cpu horsepower to decode/play the video. My E350 system can't handle hulu or netflix in HD, but does just fine on 1080p broadcast or blu-ray.

That is a factor of your hardware acceleration being broken, not CPU horsepower. There are known issues with Brazos (the E350 is a Zacate chip in the Brazos family) and Silverlight, which Netflix uses, even though Brazos supports VC-1 acceleration (the codec Silverlight uses).
Blu-rays, which are typically encoded with h.264 and sometimes VC-1, would work fine with hardware acceleration.
When using commercial video playback software on a modern computer, it's very rare that you're actually decoding anything in software. Heck, even with MPC-HC, it'll default to DXVA hardware acceleration if supported.
