Encoding of video data in a video codec involves a transform of residuals. This can be composed of a primary transform and a secondary transform. The selection of the secondary transform is effected by considering the characteristics of a block to be encoded. The selection of secondary transform can be signaled to the decoder, or inferred therein.
