Claim 3:
4. A non-transitory computer readable storage medium storing a bitstream generated by a video encoding method, the bitstream comprising:
information about a split shape mode of a current coding unit indicating one of a horizontal binary-split, a vertical binary-split, a horizontal tri-split, a vertical tri-split and no-split,
wherein:
when the split shape mode of the current coding unit is determined as the horizontal binary-split, two lower coding units are determined by splitting a height of the current coding unit in half,
when the split shape mode of the current coding unit is determined as the vertical binary-split, the two lower coding units are determined by splitting a width of the current coding unit in half,
when the split shape mode of the current coding unit is determined as the horizontal tri-split, three lower coding units are determined by splitting the height of the current coding unit by a ratio of 1:2:1,
when the split shape mode of the current coding unit is determined as the vertical tri-split, the three lower coding units are determined by splitting the width of the current coding unit by the ratio of 1:2:1,
when the split shape mode of the current coding unit is determined as the no-split, the current coding unit is decoded,
a context model is determined based on at least one of a width or a height of a neighboring coding unit of the current coding unit and at least one of the width or the height of the current coding unit, and
the information about the split shape mode of the current coding unit is encoded into the bitstream by performing entropy coding based on the context model,

wherein the neighboring coding unit includes a neighboring coding unit adjacent to the right of the current coding unit, and
wherein the neighboring coding unit is encoded before the current coding unit.
