Abstract

Versatile video coding standard known as H.266/VVC has been adopted by the Joint Video Experts Team in July 2020 Bross et al. (ITU-T and ISO/IEC JVET-S2001, 2020). It is the latest video coding standard with advanced tools to enhance coding efficiency. Notably, H.266/VVC introduces new techniques, including Multiple Transform Selection (MTS). In this paper, detailed descriptions of the new transform coding development in VVC standard are presented. The study also highlights the impact of the MTS on the VVC encoder performance through experimental research using VVC reference software VTM-14 for random access configuration. The experimental results show an increase of 8.35% in terms of time execution with an improvement of 1% in the quality of the reconstructed video along with a reduction of 1% in bitrate for a quantification parameter QP equal to 32. For a QP equal to 22, there is an increase of 15.8% in terms of time execution with an improvement of 0.056% in the quality of the reconstructed video along with a reduction of 0.445% in bitrate.
