MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517059404 A) filed by V-Nova International Limited, London, on June 20, for 'constant rate factor video encoding control.'
Inventor(s) include Ciccarelli, Lorenzo; and Meardi, Guido.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "A method of computing encoding parameters for an encoding of an input video is described. The method may be seen as a form of constant rate factor control for a multi-layer coding scheme. The method includes receiving an encoding quality factor indicating a desired visual quality for an encoding of the input video. The encoding quality factor is mapped to a base quality factor indicating a desired visual quality for a base encoding of the input video, the base encoding providing an encoding at a first level of quality. Base encoding parameters are obtained from a base encoder. The encoding quality factor, base quality factor, and base encoding parameters are mapped to enhancement encoding parameters for an enhancement encoding, wherein a combination of the base encoding and the enhancement encoding provide an encoding at a second level of quality that is higher than the first level of quality. Also, two modes for constant rate factor control are described. In a "charging" mode, an encoding quality factor is selectively modulated based on characteristics of the input video. In an "accurate" mode, an encoding quality factor is selectively recomputed based on encoding parameters."
The patent application was internationally filed on Dec. 20, 2023, under International application No.PCT/GB2023/053320.
