MPEG hammers out codec that halves bit rate

A new international standard for a video compression format was announced today. The draft was issued by the influential Moving Picture Experts Group (MPEG) which met in Stockholm in July.

“High-Efficiency Video Coding (HEVC) was the main focus and was issued as a Draft International Standard (DIS) with substantial compression efficiency over AVC, in particular for higher resolutions where the average savings are around 50 percent,” said Ericsson’s meeting notes. In video alone, almost all digital terrestrial, satellite and cable TV services rely on video codecs that MPEG has standardized. The new standard issued this week is all about bandwidth, and the reduction thereof. This is a draft standard for High Efficiency Video Coding, to enable compression levels twice as high as the current H.264/AVC standard. The format may launch in commercial products next year. The news is especially good for mobile networks, where spectrum is costly. 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,” said Per Fröjdh, Manager for Visual Technology at Ericsson Research, Group Function Technology.

A little easier on bandwidth bills! |thumb
