To display a plurality of pictures with proper quality corresponding to a display size in the case of displaying a plurality of pictures on a screen. Resource assigning section 18 assigns a resource of decoding processing, such as inverse DCT processing or movement compensation / interframe predictive decoding processing, per a picture on the basis of display size information. Inverse DCT section 12, 13 performs the inverse DCT processing using DCT coefficient with resource assigned in the resource assigning section 18 to obtain predicted error. Movement compensation / interframe predictive decoding section 14, 15 performs the movement compensation / interframe predictive decoding processing using a motion vector and the predicted error to obtain the decoded picture. Scaling section 16, 17 performs the scaling processing to the decoded picture on the basis of the display size information. |
