An architecture for the universal video codec

Several video codec applications are currently considered and there is a danger that digitisation will lead to more incompatibilities than experienced in the analogue era. A video codec architecture is thus proposed having the property to accomodate a wide range of coding algorithms (hybrid scheme), to operate on a wide bitrate range (by means of an adaptive prefilter) and able to deal with different video standards (by integration of postfilter with standards conversion).
