Tech Papers 2023: This paper discusses VVC/H.266, the newest video coding standard designed to significantly improve compression efficiency over HEVC/H.265 and provide efficient coding for a broader range of video formats.
Abstract
Live VVC encoding will facilitate the adoption of next-generation applications such as 8K terrestrial broadcasting or 8K adaptive bitrate streaming. This paper aims to provide an analysis of the capabilities of VVC for live applications by describing a real-time 8K VVC software encoder. The encoder has been extensively optimised with advanced mode decision and partitioning algorithms, SIMD instructions, and a scalable multithreading architecture. The proposed encoder achieves 24% bitrate reduction at the same quality, over a highly optimised real-time HEVC encoder that was deployed during the Tokyo 2020 Olympics games. By combining all optimizations and Intel’s 4th generation Xeon Scalable Processors the new VVC encoder reaches the performance for 8K 60 fps, 10-bit, HDR live encoding at broadcast-grade quality.
