VIDEO ENCODER, VIDEO DECODER, AND CORRESPONDING METHOD - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18337330 Titled 'VIDEO ENCODER, VIDEO DECODER, AND CORRESPONDING METHOD'
Simplified Explanation
This abstract describes a method for decoding video. It involves analyzing the video's data to determine how to transform different parts of the video. Each part, called a transform unit (TU), is assigned a serial number based on its position in the video. The method then calculates the transform coefficient for the luminance transform block of each TU. The type of transformation for each block is determined based on the split mode and the serial number of the TU. An inverse transformation is applied to the transform coefficient to obtain the reconstructed residual of the luminance transform block. Finally, a reconstructed block of the video is generated based on the reconstructed residuals.
Original Abstract Submitted
A video decoding method includes parsing a bitstream to obtain a split mode to transform units (TUs) in a current coding unit (CU). Each of the TUs includes a serial number in a one-to-one correspondence with positions of the TUs in the current CU. A transform coefficient of a luminance transform block of a current TU in the TUs is obtained. A transform type of the luminance transform block of the current TU is obtained based on the split mode and a serial number of the current TU. An inverse transform on the transform coefficient of the luminance transform block of the current TU is performed based on the transform type of the luminance transform block of the current TU to obtain a reconstructed residual of the luminance transform block of the current TU. A reconstructed block of the current CU is obtained based on the reconstructed residual.
