Abstract
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.
