obtaining a residual signal resulting from inter-picture prediction or intra-picture prediction;
inferring, from a sequence level DCT2 enabled flag in a Sequence Parameter Set (SPS), use of a Discrete Cosine Transform type 2 (DCT2) transform core for a block of a sequence of the residual signal, wherein the sequence level DCT2 enabled flag is denoted as sps_dct2_enabled_flag; and
transforming the block using the DCT2 transform core.
