Abstract
A method for encoding a video picture into a bitstream of encoded video picture data, includes: splitting the video picture into rectangular picture areas, a size of at least one rectangular picture area being different from an integer multiple of a default size of coding-tree unit encoded into the bitstream; determining a grid of coding-tree units for each rectangular picture area, a grid of coding-tree units representing a spatial partition of a rectangular picture area, each coding-tree unit representing a sub-area of a rectangular picture area, the sub-area being subdivided according to a coding tree; obtaining encoded video picture data by encoding at least one coding unit (CU) of a coding tree associated with each coding tree unit (CTU) of each grid of coding-tree unit; and writing the encoded video picture data into the bitstream.
