Looking to boost support for video over LTE mobile streaming and 4K Ultra HD, Japanese powerhouse NTT has developed compression software and an encoder engine that is fully compliant with the Main/Main10 profile of the next-generation H.265/HEVC video coding standard, which was ratified at the end of April.
The H.265/HEVC standard delivers a twofold improvement in compression efficiency compared to the prevailing H.264/AVC standard when it comes to handling compression of video data. Using a unique proprietary technology, NTT has improved that to a 2.5-fold bandwidth saving at its maximum performance, it said. "This means we are able to slash the required bit rate by 60% compared to the legacy H.264 standard, without any loss of picture quality," the company noted in a statement.
The H.265 technology was developed by the ITU to ease mobile data congestion, hold down network operator investment costs, provide users with higher definition content even on bandwidth-constrained networks, and deliver high quality video streaming over LTE lines and 4K video streaming over IPTV and other next-gen video services.
Using the H.265 encoding technology from NTT, NTT Advanced Technology Corporation (NTT-AT) has rolled out the RealFeel series HEVC software codec development kit, the HEVC-1000 SDK. With the kit, engineers have access to NTT's version of the HEVC standard in developing applications.
"Certainly, NTT-AT believes the SDK will bolster our domestic and international market share for video conversion application engines needed to produce content," NTT said. "Also, by bringing the kit out at this early date, we hope to further expand the market for video streaming which requires better picture quality accompanied by higher rates of compression. This will open the way to video streaming to smart phones and other mobile devices over LTE and other fast links, and to 4K video streaming that is currently getting a lot of worldwide exposure."
