Abstract
An example method of video coding includes receiving a video bitstream comprising a current block and identifying a first prediction mode for the current block. The method also includes mapping the first prediction mode to a corresponding intra prediction mode, and selecting a first transform set from a plurality of transform sets based on the corresponding intra prediction mode. The method further includes reconstructing the current block using the first transform set.
