Claim 2:
3. A decoding method comprising:
parsing an encoded bitstream to obtain a first parameter and a second parameter;
deriving a partition mode based on the first and second parameters; and
responsive to the derived partition mode being a first partition mode, executing the first partition mode including:
splitting a block of a picture, in a vertical direction or in a horizontal direction, into a plurality of first blocks, the plurality of first blocks including a N×2N block sized N pixels by 2N pixels;
splitting the N×2N block, wherein a ternary split is allowed to split the N×2N block in the vertical direction, which is a direction along the 2N pixels, into a plurality of sub blocks including at least one sub block sized N/4×2N, while a binary split is not allowed to split the N×2N block in the vertical direction into two sub blocks that are equally sized N/2×2N; and
decoding the plurality of sub blocks.
