FIELD: video encoding.
SUBSTANCE: invention relates to image block video encoding means. A residual signal of the resulting inter- or intra-prediction image is obtained. Carry out the derivation of the use of the DCT2 transformation kernel for the sequence of the residual signal. The block transformation is processed using the derived transformation kernel. In which the use of the DCT2 transformation kernel is derived from the sequence level DCT2 enable flag in the sequence parameter set (SPS).
EFFECT: improved compression ratio with minimal loss of image quality or no such loss at all.
