Abstract
An example method of video coding includes receiving a video bitstream comprising a current block and a syntax element and identifying an intra prediction mode for the current block. The method also includes parsing the syntax element to determine whether to change the intra prediction mode when deriving a transform set index, and deriving the transform set index for the current block based on the intra prediction mode and the parsed syntax element. The method further includes selecting a first transform set from a plurality of transform sets according to the transform set index, and reconstructing the current block using the first transform set.
