1. A method of compressing video, said method comprising the steps of:

  • determining an actual error between corresponding blocks of a current frame and a predicted frame corresponding to the current frame;

    repeating said determining step for a successive pair of the corresponding blocks;

    accumulating the actual errors to generate an accumulated error;

    inserting an I-frame as the next subsequent frame after the current frame if said accumulated error exceeds a predetermined threshold; and

    repeating said first repeating, accumulating and inserting steps until said accumulated error exceeds said threshold.
