Qualcomm shows horsepower of next-gen H.265 video FEB 29 2012...check the Vids
The next-gen video compression technology shrinks video by 40 to 45 percent compared to today's prevailing H.264. But encoding H.265 video takes a long time right now.
BARCELONA, Spain--H.264 is today's leader when it comes to mainstream video encoding technologies, but it will have to share the stage in 2013 with a successor called H.265 that can squeeze a video into nearly half the file size.
H.264, also known as the Advanced Video Codec (AVC), defines how a video can be compressed for reduced storage requirements and--very importantly given the online video explosion--for streaming across networks. H.265, also called High Efficiency Video Codec (HEVC), uses new techniques to compress video even more.
Qualcomm, a San Diego-based chipmaker that's on the international standards group developing H.265, demonstrated a preliminary version of H.265 video on an Android tablet at the Mobile World Congress show here in Barcelona.
The H.265 codec is likely to gain widespread support , but it and H.264 competes with a royalty-free alternative called VP8 that Google has released. Qualcomm competitor Nvidia has built VP8 decoding support into its newer Tegra 3 chips alongside H.264 support.
Qualcomm is bullish about the codec . If a given network capacity can sustain higher-quality video , that means mobile devices are better for entertainment. And because H.265's efficiencies come at the cost of a significantly higher need for processing power , mobile device makers have a new reason to buy the latest chips.
"We expect the standard to be ratified early next year," said Phillippe Decotigne, a Qualcomm product manager, in an interview today.

H.265 or HEVC (High Efficiency Video Coding) produces the same visual quality as AVC (H.264) High profile at only half the bit rate. In other words, it supports video files of 4K and 8K resolutions while simultaneously improving upon current streaming by cutting the required bitrate by up to 50 percent. This bit reduction gained at the expanse of higher complexity in the encoder computation thus, requiring higher CPU power then AVC High Profile. The computational complexity would be 2-10 times higher. However, decoding of HEVC would not be much higher in CPU usage then AVC High Profile decoding.
Though H.265 will require more computational power than its predecessor, it does not matter. Computer processors, especially mobile CPUs, grow more powerful every year, but our network infrastructure and bandwidth speeds are growing much more slowly. HEVC theoretically will make current HD video streaming more efficient while paving the way for a future of 4K content.
HEVC target applications are next generation HDTV and Mobile Video Streaming. It could serve up to resolutions of up to 7680 x 4320 (Ultra HDTV).

........GOOGLE is working on VP9.....up and running on chrome, (if I rem right)
