Abstract
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.
