NTT-AT Upgrades H. 265/HEVC Software CODEC SDK and File Conversion Software.
NTT Advanced Technology Corp. announced on August 19 that it launched an upgraded version of “HEVC-1000 SDK,” a software CODEC development kit compliant with the H.265/HEVC (*1) video coding standards, on August 7 and that it will launch an upgraded version of file conversion software “FileConverter 4K FC4000″ on August 26.
NTT-AT has upgraded the H.265/HEVC encoder engine employed by the two products to make it compliant with the 4K “Range Extensions” Profile (*2) (color format (*3) 4:2:2 and 10-bit bit depth (*4)), realizing high-speed and high-quality video delivery.
As TV sets compatible with the 4K or Ultra High Definition (UHD) have become available lately, a host of new services using the H.265/HEVC standard are being considered in various areas, with U.S. cable operators and online content providers declaring their intention of promoting 4K video delivery while experimental 4K TV broadcasting launched in Japan.
With “HEVC-1000 SDK” in place, the development of applications compliant with H.265/HEVC becomes easier, helping promote the development of software using 4K videos. Also, the use of “FileConverter 4K FC4000″ enables efficient production of 4K-ready content with an ordinary desktop PC, contributing greatly to the content business of content holders and online video delivery service providers.
H.265/HEVC encoder engine
The encoder engine adopted in the NTT-AT products has been upgraded. The 265/HEVC encoding algorithm developed by the Media Intelligence Laboratories, Nippon Telegraph and Telephone Corp., is programed into the encoder engine, making it the first of its kind in the world to be compliant with the 4K “Range Extensions” Profile (color format 4:2:2 and 10-bit bit depth). Its features include the “LQA algorithm” for combining high video quality with a high compression rate and “CBR (*5) control” for improved stability.
LQA (Local QP Adjustment) algorithm:
This is an algorithm for reducing data volume in video areas where the human eye cannot easily detect distortions, improving the compression rate while maintaining high video quality.
Accurate CBR control making both stable streaming and high video quality possible. Ordinarily, in CRB control, where bit-rate variations have to be controlled, achieving high video quality is difficult. With NTT-AT’s unique coding control, however, high video quality has been made possible.
“HEVC-1000 SDK” and “FileConverter 4K FC4000″ have been duly upgraded and made ready for launch.
