  • Method for motion-compensated frame-to-frame prediction coding
    Patent number: 4816906
    Abstract: A process of frame-to-frame prediction coding in which a frame is broken down into a regular block scanning field of n x n pixels and then prior to each prediction, up to four prediction methods, namely (1) block-by-block displacement vector calculation, (2) object-related displacement vector calculation, (3) nullification of the displacement, and (4) nullification of the prediction, are monitored as to the data rate to be transmitted, and the prediction method that leads to the smallest prediction errors is selected for the transmission.
