FIELD: image processing.
SUBSTANCE: invention relates to the field of image processing and, more specifically, to an encoder, a decoder and corresponding methods for obtaining the boundary power of a deblocking filter. A method for encoding and decoding is proposed. The method includes determining whether at least one of two blocks is predicted using combined inter-intra prediction (CIIP), in which the two blocks include a first block (Q block) and a second block (P block), and in which two blocks are associated with the border. Further includes setting the boundary power (Bs) of the boundary to a first value when at least one of the two blocks is predicted using CIIP; or setting the boundary power (Bs) of the boundary to a second value when neither of the two blocks is predicted using CIIP.
EFFECT: improving the efficiency of encoding/decoding.
