Abstract :
SHVC is the scalable extension of the latest video coding standard High Efficiency Video Coding (HEVC). Color Gamut Scalability (CGS) refers to a scalable use case in which base layer and enhancement layer have different color gamuts. In this case, special inter-layer prediction is needed to improve coding efficiency in SHVC. In this paper, a solution based on asymmetric 3D lookup table is presented for color gamut scalability. Compared to SHVC without CGS coding tool, the proposed solution provides 9.6% - 16.1% overall luma BD-rate reduction in different test cases.
