Abstract
An analog video interface for a digital video display, comprising an analog video input for receiving at least one analog video signal with composite or separate horizontal and vertical deflection signals; digitizing apparatus for digitizing the analog video signal; apparatus for generating a basic clock signal having a frequency at least n times a desired video frequency, where n.gtoreq.1 and for generating control signals for the digital display and a sampling clock signal for the digitizing means in synchronization with the basic clock signal. The video interface further includes determining the actual video frequency of the analog video signal from the actual received video signals and a programmable frequency synthesizer responsive to the actual video frequency for synthesizing the basic clock signal having a frequency at least n times the determined actual video frequency where n.gtoreq.1.
