Abstract
A motion picture coding apparatus for storage medium of a video rate is produced at a low cost. The coding apparatus includes an input picture re-arranging unit for changing the order of frames of input motion pictures, a storage circuit for storing therein decoded pictures of intra-coded and predictive coded pictures, an address generating unit, a motion detector for performing multi-stage motion vector search, a predictive signal generating unit for outputting an inter-frame predictive signal and a predictive difference signal, a quantizing unit, a variable length coding unit, and locally decoding unit. The predictive signal generating unit simultaneously fetches data read out from the storage circuit to the motion detector for final stage vector search to reduce access to the storage circuit. The locally decoded pictures are placed back in order of reproduced frames to monitor the decoded picture signal by a storage circuit for storing therein decoded pictures of intra-coded and predictive coded pictures of an output of the locally decoding unit and address generating unit.
