This paper describes a joint response to the Call for Proposals by Samsung, Huawei, GoPro, and HiSilicon on Video Compression with Capability beyond HEVC/H.265, jointly issued by ITU-T SG16 Q.6 (VCEG) and ISO/IEC JTC1/SC29/WG11 (MPEG). In the proposed codec, the coding framework supports hierarchical splitting with binary and ternary trees and flexible coding order representations. Additionally, novel compression tools on inter/intra prediction, in-loop filtering, and entropy coding have been proposed. The proposed compression scheme provides significantly higher compression capability than the state-of-the-art HEVC/H.265 standard for SDR (Standard Dynamic Range) category while maintaining complexity acceptable for emerging applications. When all the proposed algorithmic tools are used, the proposed video codec achieves approximately 40% bit-saving for the SDR cetegory on average compared to HEVC/H.265 anchor.
