Abstract :
The HEVC extension for Scalable Video Coding (SHVC) is currently under definition. Color Gamut Scalability (CGS) has been identified as one MPEG requirement. This paper discuss what could be the stake of CGS in the context of video distribution. Two CGS models are presented: one simple scheme based on Gain-Offset transformation, and one based on 3D color LUT, more generic. A comparison of their performances and respective advantages is carried out using different test contents trying to address realistic use cases.
