MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202618071641 A) filed by Beijing Dajia Internet Information Technology Co. , Ltd. on June 09, 2026, for Methods And Devices For Quantization And De-Quantization Design In Video Coding.
Inventors include Jhu, Hong-Jheng; Xiu, Xiaoyu; Wang, Xianglin; Chen, Yi-Wen; Ma, Tsung-Chuan Number; and Yu, Bing.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A method for video coding is provided. The method includes: determining (1101) a quantization parameter for residual data of a coding unit (CU); deriving (1102) a scale value by scaling the quantization parameter by a scale factor; determining (1103) a plurality of coefficients associated with the CU; determining (1104) a plurality of parameters associated with the CU; obtaining (1105) a plurality of bit-shifts by bit-shifting the plurality of parameters; and obtaining (1106) a quantized level based on the scale value, the plurality of coefficients, and the plurality of bit-shifts.
