Simulation color video copy guard method, from by analog video recorder and the equipment for manufacturing the tire

摘要

Shifted color burst signal into burst interval of analog color video signal is not subject to satisfied duplication and is generally spaced chrominance pulse shifted color burst signal into burst interval of analog color video signal by the pre-position with predetermined lasting time in insertion phase shifted signal chrominance pulse. Predetermined position can chrominance pulse prior to normal signal or it can defer to chrominance pulse normal signal or it and can be located at middle part chrominance pulse interval. The device manufacturing inventive method includes playback apparatus (1), whose luminance signal output (Y-axis) and terminal box (6) forms so-called S-output and the further mixer with Y/C inputs (5), whose the second input terminal is via the chrominance pulse position of circuit (4) and the video signal playback apparatus (1) of output (C groups). Playback apparatus (1) exports (HD) line synchronising signal,Clock and master clock (2) for exporting the frame synchronizing signal and output (CLK) in (VD), export the position of logical chrominance pulse signal generator (3) and the circuit chrominance pulse (4). The chrominance pulse position of circuit (4) also copies playback apparatus (1) with control signal output.
