Coding Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240223792 titled 'Coding Method and Apparatus
The video decoding method described in the abstract involves parsing a received bitstream to extract prediction information of a coding unit (CU), obtaining a target transform mode of a residual transform unit (TU), parsing the bitstream to acquire transform coefficients of the residual TU, applying inverse quantization to the transform coefficients to get dequantized coefficients, applying an inverse transform based on the target transform mode to the dequantized coefficients to obtain a residual block of the residual TU, obtaining a prediction block of the CU based on the prediction information, obtaining a video block using the residual block and the prediction block, and outputting a video sequence with a video frame containing the video block.
