Patent ID: 7272185

Claim:
A moving picture recording/reproducing apparatus for recording encoded data of a moving picture obtained through motion-compensated inter-frame prediction in a storage medium and reproducing the encoded and recorded data from the storage medium and decoding the encoded data, comprising: a first encoding module for encoding an input moving picture at a first frame rate and at a first image size; a decoding module for decoding data encoded by said first encoding module; a re-encoding module for re-encoding a predetermined frame extracted from frames decoded by said decoding module, at a second frame rate smaller than the first frame rate and at a second image size smaller than the first image size; motion vector calculation module for calculating a motion vector to be used for prediction by said re-encoding module from a motion vector decoded by said decoding module; and prediction mode control module for controlling a prediction mode of said first encoding module to make the prediction mode of said first encoding module be coincident with a prediction mode of said re-encoding module, so that said motion vector calculated by said motion vector calculation module can be used by said re-encoding module.
