Problems solved by technology

[0007] The first solution is inherently non-compliant with the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Moving Picture Experts Group-4 (MPEG-4) Part 10 Advanced Video Coding (AVC) standard / International Telecommunication Union Sector (ITU - T) 8-bit profile of the H.264 recommendation standard (hereinafter referred to as "MPEG-4 AVC standard")
The second solution meets all current standards, but requires more overhead
[0019] However, disadvantageously, previous prior art techniques cannot be used directly with bit-depth scalability

Abstract

There are provided methods and apparatus for inter-layer residue prediction for scalable video. An apparatus is described for an encoder (200) for encoding a block of a picture, or a decoder (300) for decoding a block of a picture, by applying inverse tone mapping to an inter-layer residue prediction process for the block, wherein the inverse tone mapping is performed in the pixel domain. Methods for encoding (440, 460) or decoding (540, 560) a block of a picture are also described; and performed by applying inverse tone mapping to an inter-layer residue prediction process for the block, wherein the inverse tone mapping is performed in the pixel domain.
