MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517055510 A) filed by Tencent America Llc, Palo Alto, U.S.A., on June 9, for 'signaled transform set.'
Inventor(s) include Zhao, Xin; Peringassery Krishnan, Madhu; and Liu, Shan.
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: "This disclosure relates generally to video coding/decoding and particularly for improvement of signaled transform set. One method includes receiving a coded video bitstream; extracting, based on the coded video bitstream, a set of transform coefficients for the current block; determining, based on a syntax element explicitly signaled in the coded video bitstream, a transform set index for the current block in an intra prediction mode, the transform set index indicating a transform set among a plurality of transform sets; identifying the transform set according to the transform set index; performing an inverse transform using the set of transform coefficients and the identified transform set to obtain a residual block for the current block; and reconstructing, by the device, the current block based on the residual block."
The patent application was internationally filed on Oct. 31, 2023, under International application No.PCT/US2023/036458.
