    摘要： A method for decoding video data provided in a bitstream, where the bitstream includes a coding unit (CU) coded in palette mode, includes: parsing a palette associated with the CU provided in the bitstream; parsing one or more run lengths provided in the bitstream that are associated with the CU; parsing one or more index values provided in the bitstream that associated with the CU; and parsing one or more escape pixel values provided in the bitstream that are associated with the CU. The escape pixel values may be parsed from consecutive positions in the bitstream, the consecutive positions being in the bitstream after all of the run lengths and the index values associated with the CU. The method may further include decoding the CU based on the parsed palette, parsed run lengths, parsed index values, and parsed escape values.

    摘要： In an example, system and method for coding encoded video data. 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. Each reconstructed prediction residue is added to its corresponding original prediction value to produce a current block of a picture. Generating the reconstructed prediction residue includes performing inverse quantization on blocks of quantized residue differences, wherein the inverse quantization reconstructs data to which uniform quantization residue differential pulse code modulation (RDPCM) has been applied and wherein the quantization is of the form: &Dgr;Xq=floor((X+αQ)/Q) where Q is quantization step and α is quantization offset.

    摘要： An example method of decoding video data includes determining a palette for decoding a block, the palette including entries each having a respective palette index, determining a reference run of palette indices for first pixels of the block, and determining a current run of palette indices for second pixels of the block, based on the reference run. Determining the second plurality of palette indices includes locating a reference index of the reference run, the reference index being spaced at least one line from an initial index of the current run, determining a run length of the reference run, a final index of the reference run being separated from the initial index of the current run by at least one index, copying the palette indices of the reference run as the current run of palette indices, and decoding pixels of the copied current run using the palette.

    摘要： Techniques for encoding a binary prediction vector for predicting a palette for palette-based video coding is described. In one example, a method of decoding video comprises receiving an encoded binary prediction vector for a current block of video data, decoding the encoded binary prediction vector using a run-length decoding technique, generating a palette for the current block of video data based on the binary prediction vector, the binary prediction vector comprising entries indicating whether or not previously-used palette entries are reused for the palette for the current block of video data, and decoding the current block of video data using the palette.
