Classification: CPC H | IPC H

Claim 1:
2. An image decoding apparatus comprising at least one processor, wherein the at least one processor is configured to:
determine a context model based on at least one of a width or a height of a neighboring coding unit of a current coding unit and at least one of a width or a height of the current coding unit;
obtain, from a bitstream based on the context model, information about a split shape mode of the current coding unit;
when the split shape mode of the current coding unit is determined as a horizontal binary-split based on the information about the split shape mode, determining two lower coding units by splitting the height of the current coding unit in half;
when the split shape mode of the current coding unit is determined as a vertical binary-split based on the information about the split shape mode, determining the two lower coding units by splitting the width of the current coding unit in half;
when the split shape mode of the current coding unit is determined as a horizontal tri-split based on the information about the split shape mode, determining three lower coding units 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 a vertical tri-split based on the information about the split shape mode, determining the three lower coding units by splitting the width of the current coding unit by the ratio of 1:2:1; and
when the split shape mode of the current coding unit is determined as a no-split based on the information about the split shape mode, decode the current coding unit,
wherein the neighboring coding unit includes a neighboring coding unit adjacent to the right of the current coding unit,
wherein the neighboring coding unit is decoded before the current coding unit.
