MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617094282 A) filed by Guangdong Oppo Mobile Telecommunications Corp. on August 04, 2026, for Coding Method, Decoding Method, Code Stream, Coder, Decoder And Storage Medium.
Inventor includes Wang, Fan.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: Disclosed in the present application are a coding method, a decoding method, a code stream, a coder, a decoder and a storage medium. The decoding method comprises: determining a prediction mode of the current block; when the prediction mode of the current block meets a first condition, determining a first candidate list of the current block, wherein the first candidate list indicates at least two candidate transformation kernel groups; according to the first candidate list, determining a transformation kernel of the current block; and determining a transformation coefficient of the current block and, on the basis of the transformation kernel, performing inverse transformation on the transformation coefficient of the current block, so as to determine a residual block of the current block. Thus, compression efficiency can be improved, thereby improving coding and decoding performance.
