Open source project targets HEVC codec standardization

September 12, 2013 - 3:50am
New video compression standards offer vast opportunities for video transport systems.

As innovations in video transport continue to increase the demand for high-quality content, broadcasters, engineers and designers need reliable video encoding standards. Sencore is excited to be on the ground floor of this development and witness to the progress being made in the roll-out of HEVC compression algorithms across the industry. One of the most important efforts is being made through the recently launched "x265" open source project.

According to Broadcast Engineering' Michael Grotticelli, the H.265 project was launched by Telestream as an open source initiative aimed at creating the highest quality and most efficient video codec for the High Efficiency Video Coding (HEVC) H.265 encoder. The successor to previous video compression standard H.264/MPEG-4 Advanced Video Coding (AVC), HEVC was developed through a joint effort by the ISO/IEC Moving Picture Experts Group (MPEG) and the ITU-T Video Coding Experts Group (VECG). HEVC can offer valuable benefits for broadcasters and operators alike, as well as delivering the best video experience to viewers, offering twice the data compression ratio of the maturing standard while using the same bitrate. It is able to support the latest high resolution video formats, including: Ultra HD (3840 x 2160), 4K HD (4096 x 2160), and 8K HD (8192 x 4320).

The importance of open source developments
The x265 project aims to improve on x264 codec to deliver the highest video quality at any bitrate and to use the lowest bitrate possible for a certain quality level. The open source methodology of the project enables the industry's leading minds, from broadcast engineers to video hardware developers and industry researchers, to contribute their unique perspectives to improving codec standards.

As a leader in MPEG test, measurement and analysis gear, SencoreĀ felt it was important to provide engineers like those working on x265 the tools needed to ensure compliance and consistency with the HEVC standard. When the first iteration of the HEVC standard was ratified in January of this year, Sencore started development on an in-depth HEVC analyzer. As a result of this effort, we are proud to announce the timely release of our HEVC analysis package, available on our CMA 1820 Compressed Media Analyzer at IBC 2013.

The CMA 1820 is a versatile device that offers compressed media in-depth analysis and ensures compliance with encoding standards compliance. It can be easily deployed as part of any contemporary video broadcast system, with full support for HEVC/H.265, as well as H.264, MPEG2 and VC-1 video as well as AC-3, AAC and MPEG audio. It can be used to identify and resolve any interoperability issues between advanced CODECs in digital video environments. The CMA 1820 can also be utilized for closed caption, subtitle, SCTE35-DPI and PTS/DTS alignment analysis to ensure compatibility and reliability in today's demanding multichannel distribution environments.
