Demonstration of "next generation high compression video coding technology" that can compress video considerably with high picture quality released

Used in terrestrial digital broadcasting, DVD, etc. "MPEG-2Format and Blu-ray and other "MPEG-4 AVC / H.264There are various kinds of video compression standard such as format.

Generally, it is a very difficult problem to achieve compatibility between image compression ratio and image quality, but it is a dreamlike dream that data volume can be compressed much more than before, while maintaining high image qualityNext generation high compression video encoding technology"Currently underway"CEATEC JAPAN 2010"Mitsubishi Electric booth at the exhibition.

Details are as below.
Mitsubishi Electric Booth's "Next Generation High Compression Video Coding Technology" Corner


Demos of encoded video are being performed. Full HD (1920 × 1080) picture adopting the "next generation high compression video coding technology" developed by NHK and Mitsubishi Electric on the left, with the image adopting the conventional "MPEG-4 AVC / H.264" is. As compared with the 3.9 Mbps data amount of the conventional system, which is 1/6 of the data amount of digital broadcasting (MPEG - 2), 2.0 Mbps corresponding to 1/11 of the new technology.


For this video, 3.3 Mbps for the conventional method and 0.9 Mbps for the new technology. There is a big difference.


A state of the demonstration.

YouTube - Demonstration of "next generation high compression video encoding technology" whose compression performance has doubled compared with the past


At 8 K × 4 K corresponding to 16 times the resolution of full HD to 24 Mbps. In addition, since the demo monitor only supports 4K × 2K, it is in the form of cutting out the video.


Explanation of what kind of "next generation high compression video coding technology" is. It is a technology that boasts about 4 times the "MPEG-2" and about twice the "MPEG-4 AVC / H.264" compression technology.


Unlike the conventional method, the compression size is improved by making the block size the optimum size according to the image.
