MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202617016322 A) filed by V-Nova International Ltd., London, on Feb. 13, for 'processing of residuals in video coding.'
Inventor(s) include Ciccarelli, Lorenzo; Dorovic, Katarina; and Meardi, Guido.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "A method of encoding an input signal, the method comprising: receiving an input signal; generating a set of residuals based on a difference between the input signal and a reconstructed signal; applying a transform operation to the set of residuals to generate a set of transform coefficients; applying a quantization operation to the set of transform coefficients to generate a set of quantized values; and applying an encoding operation to the set of quantized values to generate an encoded stream; wherein applying the quantization operation comprises modifying a quantized value from a first quantized value to a second quantized value in order to adjust a quantization bin of a transform coefficient, such that the transform coefficient is quantized into second quantization bin instead of a first quantization bin."
The patent application was internationally filed on Aug. 29, 2024, under International application No.PCT/GB2024/052248.
