Abstract
An input signal source of any form (e.g. camera or recorder) supplies a standard base band video wave. This video signal is fed to a conventional analog-to-digital converter (11) which samples the incoming wave train at a rate of 8 megahertz under the control of a system clock of a microprocessor (15). The microprocessor (15) recognizes the frame and line sync information from a sync detector 18 thereof, and activates a 600-byte current line memory (120 such that one line of scanned, a megahertz sampled television video information is stored therein. The first line of frame, there the microprocessor (15) computes first, second and third order differences and encodes information according to an algorithms.
