Methods and apparatus for low-complexity MTS
A next-generation video decoding technique performed by at least one computer processor including determining whether at least one parameter of a block is less than or equal to a threshold, signaling, in response to determining the parameter(s) of the block is/are less than or equal to the threshold, a horizontal transform or vertical transform, splitting, in response to determining that the at least one parameter of the block is greater than the threshold, the block into sub-blocks, applying a first signaling scheme on a luma component and a second signaling scheme on a chroma component, performing ones of transforms on the sub-blocks, and decoding a video stream by using the sub-blocks upon which the ones of the transforms are performed, where a maximum block size of the first signaling scheme is different than a maximum block size of the second signaling scheme.
