Abstract

Apparatuses and methods for encoding and decoding a video are provided. A method includes determining whether at least one of two blocks of an image in a video is predicted with a combined inter-intra prediction (CIIP), wherein the two blocks include a first block (block Q) and a second block (block P). There is a boundary between the two blocks. The method further includes setting a boundary strength (Bs) for the boundary to a first value based on determining that at least one of the two blocks is predicted with the CIIP, and performing deblocking for the boundary between the first block and the second block based on the Bs to generate a modified reconstructed block for each of the first block and the second block.
