Abstract
A method of decoding video data, the method comprising receiving a run-length sequence indicative of a binary vector, the binary vector comprising indications of locations of escape samples in a block of video data encoded using a palette-based coding mode, decoding the run-length sequence to obtain the binary vector, and decoding the block of video data using the binary vector. The method of claim 1 may further comprise receiving palette entries for the block of video data receiving one or more escape samples, and receiving a plurality of flags indicating the palette mode for each respective pixel in the block of video data.
