Abstract
Methods, systems and devices for using flexible and efficient partitioning techniques and in particular, restricting extended quadtree (EQT) partitioning, are described. An exemplary method for visual media decoding includes making a decision, based on one or more conditions, regarding a selective inclusion of one or more signaling bits for a partitioning process in a bitstream representation of a current visual media block of a plurality of visual media blocks, where the partitioning process splits the current visual media block into exactly four sub-blocks including at least one sub-block that has a size different from half of a width of the current visual media block times half of a height of the current visual media block; decoding, based on the bitstream representation, the four sub-blocks; and decoding, based on the four sub-blocks and the partitioning process, the current visual media block.
