Abstract

Provided is a motion picture encoding apparatus comprising: a signal divider for dividing a differential image block into a first domain and a second domain on the basis of a boundary within the differential image block for representing a difference between an original image and a predictive image with respect to the original image; a transform coding unit for transform-coding the first domain using a DCT (Discrete Cosine Transform); a quantization unit for quantizing an output of the transform coding unit in a frequency domain; a spatial domain quantization unit for quantizing the second domain in a spatial domain; and an entropy encoding unit for performing an entropy encoding using outputs of the quantization unit and the spatial domain quantization unit.
