decoding coded information for a transform block (TB) from a coded video bitstream, the coded information indicating a primary transform type used for the TB;
entropy decoding a secondary transform index that is signaled in the coded video bitstream, a value of the secondary transform index being entropy decoded is dependent on the primary transform type used for the TB, the secondary transform index indicating a secondary transform in a set of secondary transforms that is to be performed on the TB; and
performing the secondary transform indicated by the secondary transform index on the TB.
