Tokyo, March 1, 2013 - Video coding technology developed by NEC Corporation (NEC; TSE: 6701), in collaboration with several partners, has been adopted in the final draft international standard for high efficiency video coding (HEVC) (*1), a new international video coding standard. HEVC is scheduled to be an international standard this coming May.
HEVC is a next-generation video coding standard that is suitable for online distribution of 4K video (*2), super high vision broadcasting (*3) and distribution of full HD video (*4) for mobile devices.
In recent years, the spread of smartphones and the launch of Long Term Evolution (LTE) services have led to an increased use of video contents via mobile communication networks. As smartphone and tablet device displays become more precise, video contents are being released at increasingly higher resolutions. This is likely to trigger a drastic increase in the amount of video data delivered over networks, possibly causing delays or failures in distribution. As a result, there is a need to facilitate the use of video content through the development and standardization of technologies that provide high compression rates.
The ITU-T and ISO/IEC are international standardization groups that developed HEVC, an international video coding standard that achieves high compression rates for next-generation high-resolution video. HEVC supports a wide range of capacities, including low-resolution video like QWVGA as well as high-definition video such as 4K and super high vision broadcasting. It accomplishes twice the compression efficiency of state-of-the-art Advanced Video Coding (AVC). This enables distribution of full HD video content via mobile communication networks, as well as online distribution of highly realistic 4K video and super high vision broadcasting.
NEC recently developed (1) predictive coding technology for image quality control parameters in order to adjust the compression rate and optimization of image quality for each detailed region of an image (technology developed in collaboration with Canon Inc.,
JVC KENWOOD Corporation, Sony Corporation and others) and (2) PCM coding technology for preventing images containing complex patterns and designs from becoming too large in terms of the volume of compressed data.
Key features of these new technologies include the following:
(*1) As of the end of January 2013, ISO/IEC and ITU-T had approved HEVC as ISO/IEC 23008-2 High Efficiency Video Coding and ITU-T Rec. H.265 respectively, as the final draft international standard. HEVC is comprised of video coding technologies developed by several companies including NEC.
