ABSTRACT:
A recording medium having recorded thereon information related to coded data of an image sequence; wherein the information related to coded data of an image sequence is a set of coded frame information of a plurality of frames of an image sequence; wherein the coded frame information includes: information related to a difference image between an image of a current frame and a prediction image of the current frame, the prediction image being synthesized by performing motion compensation, information related to motion vectors estimated in performing the motion compensation, and rounding method information specifying either a positive rounding method or a negative rounding method for interpolating intensity values of pixels in performing the motion compensation when the input image is coded as a P frame, wherein no rounding method information is included in the coded frame information when the input image is coded as an I frame.
