1. A picture encoding method, by an encoding apparatus, the method comprising:
generating a skip flag for indicating whether a skip mode is applied to a current coding unit;
generating prediction mode and partition type information based on the skip flag representing that the skip mode is not applied for the current coding unit, wherein the prediction mode represents whether an inter prediction is applied for the current coding unit and the partition type represents a partition type for the current coding unit, wherein a prediction unit is derived from the current coding unit based on the partition type;
generating a merge flag for indicating whether a merge mode is applied to the prediction unit, based on the skip flag representing that the skip mode is not applied for the current coding unit and the prediction mode representing that the inter prediction is applied for the current coding unit;
performing inter prediction on the prediction unit based on the merge flag representing whether merge mode is applied for the prediction unit; and
encoding picture information including the skip flag, the prediction mode and partition type information, and the merge flag,
wherein the prediction mode and partition type information is signaled between signaling of the skip flag and signaling of the merge flag,
wherein the skip flag is signaled before signaling of the merge flag,
wherein a split flag related to whether a coding unit is split into coding units is signaled,
wherein the current coding unit is derived based on the split flag before signaling of the skip flag,
wherein, for the inter prediction, the partition type includes a binary code for the partition type used for the inter prediction of the current coding unit,
wherein, for the inter prediction, the partition type indicates one of partition types including 2N×2N partition type, 2N×N partition type, and N×2N partition type,
wherein a binary code for the 2N×2N partition type is “1”, a binary code for the 2N×N partition type is “01”, and a binary code for the N×2N partition type is “001”, and
wherein the skip flag and the prediction mode and partition type information are signaled at a coding unit (CU) level, and the merge flag is signaled at a prediction unit (PU) level.
