BBC R&D Confirms H.265/HEVC Efficiency Gains Over H.264/AVC

The results and an extensive analysis of the formal subjective verification tests of the H.265/HEVC video compression standard are published in the IEEE Transactions on Circuits and Systems for Video Technology (TCSVT), January 2016. BBC R&D video coding research team focused on evaluations of UHD content and definition of analytics as part of standardisation process and presented in this paper.

The High Efficiency Video Coding (HEVC) standard has been developed jointly by the two standardisation bodies ITU and ISO (as has been the practice with all major video coding standards in the past 3 decades); in this instance as the Joint Collaborative Team on Video Coding (JCT-VC). The main goal of the process was to provide significantly improved video compression compared with its predecessors; H.264/AVC being the most recent. HEVC standard was ratified in 2013 as H.265 by the ITU-T and as MPEG-H Part 2 by ISO/IEC. The associated formal subjective verification tests leading to the results presented here were carried out on behalf of the JCT-VC in Feb/March 2014.
