Abstract: A video decoder may obtain a syntax element from a bitstream comprising an encoded representation of a block of video data. The block comprises a series of runs, each of which may consist of one pixel or two or more consecutive pixels. Furthermore, the video decoder may obtain a set of palette run length syntax elements indicating lengths of one or more of the runs. The video decoder may determine, based on the syntax element, that the palette run length syntax elements do not include a palette run length syntax element indicating a length of the first run. Rather, the video decoder determines, based on the lengths indicated by the set of palette run syntax elements, the length of the first run. The video decoder may determine, based on the palette sample modes of the pixels, palette indices of the pixels, each indicating an entry in a palette.

Abstract: Techniques are described for palette-based video coding. In palette-based coding, a video coder may form a “palette” as a table of colors for representing video data of a particular area (e.g., a given block). Rather than coding actual pixel values (or their residuals), the video coder may code palette index values for one or more of the pixels that correspond to entries in the palette representing the colors of the pixels. A palette may be explicitly encoded, predicted from previous palette entries, or a combination thereof. In this disclosure, techniques are described for coding a block of video data that has a single color value using a single color mode as a sub-mode of a palette coding mode. The disclosed techniques enable a block having a single color value to be coded with a reduced number of bits compared to a normal mode of the palette coding mode.

A quantized residue differences block associated with a current block of a picture is generated and a reconstructed prediction residue for each quantized residue difference in the block of quantized residue differences is generated.

The method includes responsive to determining that the number of entries is one, and that the block does not include any escape pixels, bypassing decoding index values for the pixel values of the block, and determining the pixel values of the block to be equal to the one entry in the palette.
