FIELD: computer engineering; video information recording and reproducing systems. SUBSTANCE: device reproducing video information recorded in digital form on record medium that implements existing method has record medium drive, digital output connected to it, analog-to-digital converter, and analog output. Novelty is that device has signal detector used to detect copy inhibit information in digital video signal and signal generator to shape analog copying protection signal in response to detected copy inhibit information, as well as to modify output analog video signal by means of generated copying protection analog signal; digital-to-analog converter is connected to record medium drive. EFFECT: provision for protecting any video information against copying. 47 cl, 2 dwg
