ADVANCED PALETTE PREDICTION AND SIGNALING

摘要

A video coder may determine a palette predictor list comprising one or more candidates. Each respective candidate in the palette predictor list specifies a value of a different respective reconstructed neighboring pixel from among one or more reconstructed neighboring pixels. Each of the one or more reconstructed neighboring pixels is in a line above or a column left of a current block of the video data. The video coder may include, in a palette for the current block, at least one candidate in the palette predictor list.

1. A method of decoding video data, the method comprising:
determining a palette predictor list comprising one or more candidates, each respective candidate in the palette predictor list specifying at least one sample value of a different respective reconstructed neighboring pixel from among one or more reconstructed neighboring pixels, wherein each of the one or more reconstructed neighboring pixels is in a line above or a column left of a current block of the video data; including, in a palette for the current block, at least one candidate in the palette predictor list; obtaining, based on one or more syntax elements signaled in a bitstream, an index value for a pixel of the current block; identifying a palette entry in the palette that corresponds to the index value for the pixel; and determining, based on the at least one sample value specified by the identified palette entry, at least one reconstructed sample value of the pixel.
