Abstract: A method of simplified depth-based block partitioning (DBBP) for three-dimensional and multi-view video coding is disclosed. In one embodiment, the method receives input data associated with a current texture block in a dependent view, and determines a corresponding depth block or a reference texture block in a reference view for the current texture block. Then, the method derives a representative value based on the corresponding depth block or the reference texture block, and generates a current segmentation mask from the corresponding depth block or the reference texture block. Then, the method selects a current block partition from block partition candidates, wherein the representative value is used for generating the segmentation mask or selecting the current block partition or both, and applies DBBP coding to the current texture block according to the current segmentation mask generated and the current block partition selected.

Abstract: A method and apparatus for Intra prediction coding in multi-view video coding, three-dimensional video coding, or screen content video coding are disclosed. A first filtering-disable-flag associated with a high-level video data is determined to indicate whether to disable at least one filter from a filter group. If the first filtering-disable-flag is asserted, one or more selected Intra prediction modes from an Intra prediction mode group is determined, and at least one filter from the filter group for the current block is skipped if the current Intra prediction mode of the current block belongs to the selected Intra prediction modes. The system may further determine a second filtering-disable-flag associated with a low-level video data corresponding to a current block level or a higher level than the current block level to disable said at least one filter from a filter group for the low-level video data.

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.
