Abstract
A method and apparatus for depth lookup table (DLT) signaling in a three-dimensional and multi-view coding system. The method identifies one or more pictures to be processed. If one or more pictures contain depth data, then the method determines the DLT associated with said one or more pictures, applies predictive coding to the DLT based on the previous DLT, includes syntax related to the DLT in the PPS, and includes first bit-depth information related to first depth samples of the DLT in the PPS. The first bit-depth information is consistent with second bit depth information signaled in a sequence level. The method further signals the PPS in a video bitstream for a sequence including said one or more pictures. A circuit is also provided that embodies circuitry configured to carry out the operations specified above.
