Full Title
Methods or arrangements for coding, decoding, compressing or decompressing digital video signals > using adaptive coding > characterised by the element, parameter or selection affected or controlled by the adaptive coding > Selection from among a plurality of transforms or standards, e.g. selection between discrete cosine transform [DCT] and sub-band transform or selection between H.263 and H.264
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
