1. A video decoding method comprising:
obtaining encoding order change allowance information with respect to an upper data unit comprising a left coding unit and a right coding unit, wherein the encoding order change allowance information indicates whether a change in an encoding order of coding units comprised in the upper data unit is allowed,
when the encoding order change allowance information indicates that the change in the encoding order of the coding units is allowed, obtaining encoding order information indicating whether the left coding unit is decoded prior to the right coding unit or the right coding unit is decoded prior to the left coding unit, and determining an encoding order of the left coding unit and the right coding unit based on the encoding order information;
when the encoding order change allowance information indicates that the change in the when the encoding order change allowance information indicates that the change in the encoding order of the coding units is not allowed, determining an encoding order of the left coding unit and the right coding unit based on a first encoding order; and
decoding the left coding unit and the right coding unit according to the determined encoding order,
wherein the first encoding order is identical to an encoding order from a left largest coding unit to a right largest coding unit, the left largest coding unit and the right largest coding unit being included in the upper data unit.
