1. A method comprising:
transcoding, by a computing device, a first block from a spatial region, the first block associated with a first block tree pattern defining a structure of splitting a block into smaller blocks;
including, by the computing device, a bit string of bits for the first block tree pattern in an encoded bitstream;
determining, by the computing device, a location of the first block in the spatial region when the first block tree pattern of the first block can be reused for a second block tree pattern of a second block, wherein the spatial region includes a plurality of blocks and the location is based on the first block being one of the plurality of blocks in the spatial region; and
including, by the computing device, information for the second block in the encoded bitstream that indicates the location of the first block in the spatial region without including a bit string of bits for the second block tree pattern, wherein the location allows the bit string of bits for the first block tree pattern to be retrieved for use to decode the second block from the encoded bitstream.
