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.
