Abstract: A method of IntraBC coding using restricted reference area is disclosed. A reference block is selected from an available ladder-shaped reference area comprising previously processed blocks before the current working block in the current CTU row and previously processed blocks in one or more previous CTU rows. A location of a last previously processed block of a second previous CTU row that is one CTU row farther away from the current CTU row than a first previous CTU row is always in a same vertical location or after a same vertical position of a last previously processed block of the first previous CTU row. The current picture may be partitioned into multiple CTU rows for applying wavefront parallel processing (WPP) on the multiple CTU rows, where the current working block corresponds to a current working block. Similar restrictions may also be applied to slice/tile-based parallel processing.

Abstract: A method and apparatus for palette coding of a block of video data using a shared palette/palette prediction buffer are disclosed. The system receives a bitstream including compressed data associated with a current palette coded block and determines a palette predictor for the current palette coded block stored in a shared palette/palette predictor buffer. Reuse flags for entries of the current palette are used to update the current palette stored in the shared palette/palette predictor buffer. Any new signaled entry will be inserted to the shared palette/palette predictor buffer. An updated palette predictor for a next palette coded block is generated accordingly. A method of palette management and initialization for first palette-coded block in a high-level video structure is also disclosed. The high-level video structure may correspond to a slice, wavefront, sequence or picture.

Abstract: Method and apparatus for coding a block of video data using palette coding in a video coding are disclosed. According to one embodiment, whether there is only one single palette index in the current block is determined first. If there is only one single palette index in the current block, signaling a current palette index map for the current block is omitted at an encoder side or parsing any syntax for decoding the current palette index map for the current block is omitted at a decoder side. The decision regarding whether there is only one single palette index in the current block is based on one or more syntax elements not corresponding to palette index coding.

Abstract: A method and apparatus for palette coding of a block of video data by initializing the palette or triplet palette or using a selected palette or triplet palette from a preceding image area for the beginning block of the current image area are disclosed. The method receives input data associated with a current image area consisting of multiple blocks. For the beginning block, the palette predictor is determined based on an initial palette or triplet palette or based on a selected palette or triplet palette associated with a selected block located at a location before the end of a preceding image area. For blocks of the current image area, palette coding is applied to the blocks, where at least one block uses the palette predictor for the beginning block as the palette predictor.

Abstract: A method for palette coding is disclosed. In an encoder side, the method determines whether a first block is coded using a palette coding mode or a non-palette coding. If the first block is coded using the non-palette coding mode, a first color table for the first block is derived based on one or more color tables associated with one or more previously processed blocks. If the first block is coded using the palette coding mode, the first color table is derived from the first block. A second block coded after the first block may use the first color table as a palette prediction. At the decoder side, if the current block is coded using the palette coding mode, a first color table based on a previous coded block is derived and the current block is decoded using a first color table as a palette predictor.

Abstract: A method and apparatus for palette prediction and sharing according to the present invention are disclosed. A method incorporating an embodiment of the present invention determines one or more palette sharing flags for the current block. A set of current palettes corresponding to the set of color components is generated according to the palette sharing flags. If a first palette sharing flag is asserted, one or more current palettes indicated by the first palette sharing flag are copied entirely from one or more reference palettes of a set of reference palettes. If the first palette sharing flag is not asserted, one or more current palettes indicated by the first palette sharing flag are derived from a bitstream associated with the video data. Encoding or decoding is then applied to the current block according to the set of current palettes.

Abstract: A method and apparatus for color index coding of a block of video data using index prediction based on reconstructed neighboring pixels are disclosed. In one embodiment, color index encoding or decoding is applied to the current pixel indices by deriving index prediction from neighboring pixel indices of the reconstructed neighboring pixels. The reconstructed neighboring pixel values are first transformed into the neighboring pixel indices according to a quantization table to map between major color indices and major color values of the current block. The quantization table can be based on a major color table for the current block or can also be derived at a decoder side. The decoding process may reconstruct the current pixels by converting decoded current pixel indices to reconstructed current pixel values according to the quantization table or by directly copying the reconstructed neighboring pixel values indicated by decoded current pixel indices.

Abstract: A method of RDPCM (Residue Differential Pulse-Code Modulation) coding incorporating unified Intra and Inter RDPCM coding is disclosed.

A method of extending Inter RDPCM coding to blocks coded in the IntraBC prediction mode. RDPCM processing in the vertical or horizontal direction is applied to IntraBC residue.

The star-shaped spatial filter includes a first linear arrangement of coefficients that extend outwardly in a first diagonal direction from a center pixel coefficient, a second linear arrangement of coefficients that extend outwardly in a second diagonal direction, and two linear arrangements of coefficients that extend outwardly in horizontal and vertical directions from the center pixel coefficient from the center pixel coefficient. The second diagonal direction is oriented in a different direction relative to the first diagonal direction.

Abstract: Various implementations address depth coding and related disciplines. In one particular implementation, a segmentation is determined for a particular portion of a video image in a sequence of video images. The segmentation is determined based on reference depth indicators that are associated with at least a portion of one video image in the sequence of video images. Target depth indicators associated with the particular portion of the video image are processed. The processing is based on the determined segmentation in the particular portion of the video image. In another particular implementation, a segmentation is determined for at least a given portion of a video image based on depth indicators associated with the given portion. The segmentation is extended from the given portion into a target portion of the video image based on pixel values in the given portion and on pixel values in the target portion.
