1. A system comprising:
an encoder comprising circuitry configured to generate a palette table based in part on calculated histograms for different subsets of bits of a given pixel component of pixels of a block of video data; and
a decoder comprising circuitry configured to:
receive the palette table and the video data from the encoder; and
decode the video data based at least in part on the palette table.
