Abstract
In the motion picture data converter, an MPEG-2 decoding unit decodes motion picture data in an MPEG-2 format into motion picture data in an non-compressed format, a motion vector extraction unit extracts motion vector information from the motion picture data being decoded in said MPEG-2 decoding unit, a motion compensation unit generates the motion vector information in the MPEG-4 format, by causing the extracted motion vector information to be reflected in the motion compensation processing for the MPEG-4 format, and executes the motion compensation processing based on the motion vector information, and an MPEG-4 encoding unit encodes motion picture data in the MPEG-4 format, using the motion compensation processed data and the motion picture data in the non-compressed format.
