AVC tests completed by MPEG

Having completed a round of verification tests on AVC, the new video coding standard, MPEG announced that the new technology significantly outperforms the coding efficiency of all prior standards.

The AVC standard was expected to result in significant performance improvements. The MPEG committee confirmed that the overall test results showed that the AVC standard achieved a coding efficiency improvement of 1.5 times or greater in 78 percent (66 out of 85) of the statistically conclusive cases. Several tested cases even showed improvements of four times or greater in terms of the bit rate needed to achieve statistically-equivalent perceptual video quality.

AVC is a recently completed standard that was developed by the Joint Video Team (JVT), a collaborative effort consisting of experts from both ISO/IEC’s MPEG workgroup and the ITU-T’s VCEG organizations.

Using rigorous testing methodology including formal perceptual quality measurement and extensive statistical analysis, the tests spanned a broad range of application areas, video resolutions, bit rates, etc., and compared the capabilities of the new AVC standard to several prior standards including MPEG-2, MPEG-4 part 2 Simple Profile, and MPEG-4 part 2 Advanced Simple Profile.

Analysts: TV Regs 'Not as Dire as We Thought'
We feel the negatives are known and are a lot more comfortable recommending the space.
