MPEG Hammers Out Codec That Halves Bit Rate

The Moving Picture Experts Group (MPEG) has announced a new international standard for a video compression format.
Bandwidth and its reduction is the focus of the draft standard for High Efficiency Video Coding, which would enable compression levels twice as high as the current H.264/AVC standard. The format is especially good news for mobile networks, where spectrum is costly, as service providers will be able to launch more video services with the spectrum that is currently available.
"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 Ericsson Research's Per Frojdh.
MPEG met in Stockholm in July, and drew 450 participants from 26 countries, representing telecoms, computer, TV, and consumer electronics industries. "High-Efficiency Video Coding was the main focus and was issued as a Draft International Standard with substantial compression efficiency over AVC, in particular for higher resolutions where the average savings are around 50 percent," according to Ericsson's meeting notes. The format could launch in commercial products next year.
