Selective signaling of inter transform types and/or transform sets

Abstract

An example method of video decoding includes receiving a video bitstream comprising a plurality of blocks corresponding to a plurality of pictures, the plurality of blocks including a first block. When the first block is an inter coded block, the method includes determining, based on coded information including an end of block (EOB) value, whether transform information is signaled for the first block, the transform information including at least one of a transform type and a transform set. The method also includes, when the transform information is signaled for the first block, parsing the transform information from one or more indicators of the video bitstream, and, when the transform information is not signaled for the first block, deriving the transform information without parsing the one or more indicators. The method further includes decoding the first block by applying an inverse transform to the first block using the transform information.
