OREANDA-NEWS. Nippon Telegraph & Telephone Corp. has developed a new software encoder engine for the latest international video coding standard called High Efficiency Video Coding (HEVC), which supports Range Extensions.

HEVC Range Extensions handle formats used for on-site video contributions, such as more accurate chrominance sub-sampling (4:2:2 format) and higher bit-depth (12-bit). Contribution video involves 30% more data than distribution video, so shorter compression time and higher compression rates are needed. Accordingly, a new HEVC software encoder engine was developed to support range extensions, introducing new technologies to increase speed and image quality.

HEVC Range Extensions are needed to compress contribution video. With our software encoder, contribution video of broadcasters and content providers can be compressed using HEVC, enabling reduction of storage cost and network traffic. By taking the lead in implementing an encoder engine supporting range extensions, we have contributed to invigorating future markets for 4K and 8K video, and to developing delivery services for even better-quality video.

This encoder engine is being exhibited in the NTT booth (South Hall Upper Level, SU5021) at NAB 2014, the largest broadcasting technology trade show in the industry, held April 7 to 10 in Las Vegas.
