MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202517043923 A) filed by Guangdong Oppo Mobile Telecommunications Corp. Ltd., Guangdong, China, on May 6, for 'encoding method, decoding method, code stream, encoder, decoder, and storage medium.'
Inventor(s) include Huo, Junyan; Ma, Yanzhuo; Yang, Fuzheng; Hao, Xue; and Li, Ming.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "Disclosed in embodiments of the present application are an encoding method, a decoding method, a code stream, an encoder, a decoder, and a storage medium. A method comprises: determining a first color component block of the current block; if a prediction mode of the first color component block is an IBC mode, determining a first block vector parameter of the first color component block; determining a target block vector parameter of a second color component of the current block according to the first block vector parameter of the first color component block; and performing prediction processing in an IBC extension mode on the second color component of the current block according to the target block vector parameter to determine a predicted value of the second color component of the current block. In this way, the accuracy of chroma prediction can be improved, so that the encoding/decoding efficiency can be improved."
The patent application was internationally filed on Oct. 13, 2022, under International application No.PCT/CN2022/125208.
