  • Patent number: 12671825
    Abstract: A method for video coding uses various block partitioning structures. A method performed by a video decoding apparatus includes decoding, from a bitstream, a width and a height of the current block, and a split flag indicating whether the current block is to be partitioned. The method also includes checking for a value of the split flag. If the split flag is false, the method further includes checking whether the aspect ratio satisfies a preset first condition and whether the width and the height satisfy a preset second condition. If the aspect ratio satisfies the first condition and if the width and the height satisfy the second condition, the method further includes decoding from the bitstream a sequential split flag indicating an application of a sequential quad-tree structure. If the sequential split flag is true, the method further includes partitioning the current block into lower blocks by using the sequential quad-tree structure.

  • Publication number: 20260156296
    Abstract: A method and an apparatus are disclosed for video coding utilizing prediction-transform skipping. In the disclosed embodiments, a video decoding device decodes a prediction skipping flag and a quantized transform block of the current block. The video decoding device inversely quantizes the quantized transform block to generate an inversely quantized transform block of the current block. When the prediction skipping flag is true, the video decoding device inversely transforms the inversely quantized transform block to generate a reconstructed block and stores the reconstructed block to filter the current picture and predict a next block.
