Inventors include Huo, Junyan; Ma, Yanzhuo; Yang, Fuzheng; Hao, Xue; and Li, Ming.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present application discloses an encoding method, a decoding method, a code stream, an encoder, a decoder, and a storage medium. The method comprises: determining prediction parameters of a current block; on the basis of the prediction parameters, determining a first reference prediction parameter set of the current block, wherein the first reference prediction parameter set comprises one or more first candidate reference prediction parameters; on the basis of the first reference prediction parameter set, determining a first color component reference sample value and a second color component reference sample value of the current block; on the basis of the first color component reference sample value and the second color component reference sample value, determining a mapping relationship between a first color component and a second color component; and on the basis of the mapping relationship and a first color component sample value of the current block, determining a predicted value of the second color component of the current block. In this way, the uniformity of chroma prediction can be improved, the accuracy of chroma prediction can also be improved, the code rate can be saved, and the encoding and decoding efficiency can be improved.
