Abstract

Disclosed are a method, and an apparatus, for setting the size of an encoding unit. The encoding apparatus according to the present invention may comprise: a prediction mode setting unit which sets a prediction mode for the encoding unit in a present depth; and a determination unit which, if the above-set prediction mode corresponds to a predetermined threshold value, omits a determination on an encoding unit of a sub-depth and sets the size of the encoding unit of the present depth to be the size of an optimum encoding unit. The method and apparatus of the present invention exhibit the effect of enabling the time required for encoding motion pictures to be shortened in all devices which use the encoding apparatus.
