Method, apparatus, and computer program for video coding

Abstract

To provide methods and apparatuses for video encoding / decoding.SOLUTION: A method of an apparatus for video decoding includes: decoding prediction information of a current block in a current picture from a coded video bitstream, the prediction information being indicative of an inter prediction mode having a probability that a refinement technique based on a first reference picture and a second reference picture is used; determining whether a first equal weighting condition of chroma components from the first reference picture and the second reference picture is satisfied; and disabling, in response to the fact that the first equal weighting condition of the chroma components from the first reference picture and the second reference picture is not satisfied, the refinement technique in a reconstruction of a sample in the current block.SELECTED DRAWING: Figure 12
