MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517065832 A) filed by Guangdong Oppo Mobile Telecommunications Corp. Ltd., Guangdong, China, on July 10, for 'video encoder, video encoding method, video decoder, video decoding method.'
Inventor(s) include Gan, Jonathan; Yu, Yue; and Yu, Haoping.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "The video encoding method, the video decoding method, the video encoder and the video decoder are provided. The video decoder includes an entropy decoding module, a prediction module, an inverse quantization module, an inverse transform module and a reconstruction module. The entropy decoding module receives an input bitstream. The prediction module determines a prediction block. The entropy decoding module decodes the input bitstream to obtain a plurality of quantized coefficients and a NSPT index. The inverse quantization module inversely quantizes the quantized coefficients to generate a plurality of reconstructed coefficients. In response to a current coding block (CB) having 8 16, 16 8 or 16 16 block size, the inverse transform module executes an inverse non-separable primary transform (NSPT) on the reconstructed coefficients to generate a reconstructed residual block based on a kernel. The reconstruction module generates a reconstructed CB according to the reconstructed residual block and the prediction block."
The patent application was internationally filed on Nov. 24, 2023, under International application No.PCT/US2023/081029.
