Abstract
In an example, a method of decoding video data may include receiving a palette mode encoded block of video data of a picture. The method may include receiving encoded palette mode information for the palette mode encoded block of video data. The encoded palette mode information may include a plurality of instances of a first syntax element and a plurality of syntax elements that are different from the first syntax element. The method may include decoding, using bypass mode, the plurality of instances of the first syntax element before decoding the plurality of syntax elements that are different from the first syntax element using context mode. The method may include decoding, using context mode, the plurality of syntax elements that are different from the first syntax element after decoding the plurality of instances of the first syntax element using bypass mode.
