Abstract: A method and apparatus of video coding for a block of depth data or texture data coded in SSM (Single Sample Mode) are disclosed. Embodiments according to the present invention construct a sample candidate list comprising one or more single color candidates corresponding to one or more representative samples of one or more previous SSM-coded blocks, or one or more palette color candidates corresponding to one or more previously used colors in one or more previous palettes associated with one or more palette-coded blocks, or both. A selected sample candidate is then determined from the sample candidate list and the selected sample candidate is used to encode or decode the current block by representing the whole current block by this selected sample candidate. Spatial and/or temporal candidates from previously SSM-coded blocks can also be included in the sample candidate list.

Abstract: A method and apparatus of video coding including a Single Sample Mode are disclosed. Embodiments according to the present invention construct a sample candidate list comprising one or more sample candidates from previously reconstructed neighboring samples of the current depth block or the current texture block. A sample candidate is selected from the sample candidate list and the selected sample candidate is used as reconstructed samples for the current depth block or the current texture block. A sample candidate index indicating the selected sample candidate can be signaled at the encoder side or parsed at the decoder side. Alternatively, the sample candidate index can be derived implicitly.

Abstract: A method and apparatus for deriving MV/MVP (motion vector or motion vector predictor) or DV/DVP (disparity vector or disparity vector predictor) associated Skip mode, Merge mode or Inter mode for a block of a current picture in three-dimensional (3D) video coding are disclosed. The 3D video coding may use temporal prediction and inter-view prediction to exploit temporal and inter-view correlation. MV/DV prediction is applied to reduce bitrate associated with MV/DV coding. The MV/MVP or DV/DVP for a block is derived from spatial candidates, temporal candidates and inter-view candidates. For the inter-view candidate, the position of the inter-view co-located block can be located using a global disparity vector (GDV) or warping the current block onto the co-located picture according to the depth information. The candidate can also be derived as the vector corresponding to warping the current block onto the co-located picture according to the depth information.

Abstract: A method and apparatus for palette coding of a block of video data using a candidate prediction mode list with syntax redundancy removed are disclosed. In one embodiment, whether a redundant prediction mode exists in the candidate prediction mode list for the current samples of the current block is determined based on the candidate prediction mode list and the previous prediction mode associated with the previous samples. If the redundant prediction mode exists in the candidate prediction mode list, the redundant prediction mode is removed from the candidate prediction mode list to generate a reduced candidate prediction mode list. In another embodiment, whether a redundant predictor exists in a candidate predictor list for a current sample of the current block is determined based on a condition related to one or more predictors for the current sample of the current block.

Abstract: A method and apparatus for palette coding of a block of video data using multiple color index scanning orders are disclosed. The system determines a scanning direction for the current block, where the scanning direction is selected from a scan group consisting of at least one non-horizontal scan. If the non-horizontal scan is used, the color indices of the current block are encoded or decoded according to the non-horizontal scan using a palette or a triplet palette. In another embodiment, the system uses a transposed color index map to code the color indices.

Abstract: A method and apparatus for deriving a scaled motion vector (MV) for a current block based on a candidate MV associated with a candidate block determines a first picture distance between a current picture corresponding to the current block and a target reference picture pointed to by a current motion vector of the current block, and then determines a second picture distance between a candidate picture corresponding to the candidate block and a candidate reference picture pointed to by the candidate MV of the candidate block. The method further determines a pre-scaled distance division having a first value related to dividing a pre-scaling factor by the second picture distance, and determines an intermediate scaling factor by right-shifting a multiplication result associated with the first picture distance and the pre-scaled distance division by q bits, wherein q is a positive integer.

Abstract: Methods to overcome issues associated with predictors being an Escape pixel in palette coding using a copy mode are disclosed. According to one embodiment, if the predictor for a copy-above mode is an Escape pixel, the pixel value of the current Escape pixel is transmitted so that it can be reconstructed using the transmitted pixel value. In another embodiment, restriction is applied to the encoder side, where in the copy-above mode, the copy-above run is terminated or the copy-above mode is not selected for the current pixel whenever an above pixel located above a current pixel is an Escape pixel. In yet another embodiment, directly copying the Escape value is used, where both the Escape index and Escape value, or the reconstructed pixel value of the predictor is directly copied to reconstruct a current pixel when the predictor is an Escape pixel.

Abstract: In a palette prediction that includes a copy-above mode for predicting one or more first pixels based on one or more above pixels located above said one or more first pixels correspondingly, a method of palette mode coding using palette prediction for a picture includes receiving input data associated with a current block and determining a current coding mode for one or more current pixels. If the current coding mode corresponds to the copy-above mode, then the method identifies one or more above pixels located above said one or more current pixels correspondingly, wherein said one or more above pixels are restricted to be non-Escape pixels. The method further encodes the one or more current pixels by using said one or more above pixels as predictors.

Abstract: A method of coding a block of video data using palette coding is disclosed. According to the present invention, when a previous block is available, the system receives first information related to a previous palette set corresponding to previous palettes/triplet palette, and second information related to a previous palette predictor set corresponding to previous palette predictors/triplet-palette predictors associated with the previous block. The system then derives a current palette predictor set corresponding to current palette predictors/triplet-palette predictor associated with the current block based on the previous palette set and the previous palette predictor set by including at least one unused color or triplet of the previous palette predictor set in the current palette predictor set. A current palette set corresponding to current palettes/triplet-palette associated with the current block is derived from the current palette predictor set for palette encoding or decoding.
