Abstract
New methods of allocation and video signal masking from leak on technical channels are experimentally investigated by adaptive synchronous video noise color frames. The purpose of pilot studies is justification and practical use of new methods of processing, an assessment of parameters of clock pulses a priori unknown in noise for allocation and recovery of the video frames in information leakage channels, and also a method of active masking synchronous and adaptive video noise frames of the motionless (static) and mobile (dynamic) video frame in channels of leakage of video signals. Masking of the offered test video footage by dynamic casual video noise and adaptive video noise frames is investigated, recovery of the video frame is realized by the developed algorithm and a software of synchronous accumulation of the video frames which considerably improves the relation signal/noise. Pilot studies confirmed advantages of masking of the static video frame with adaptive synchronous video noise frames which in comparison with dynamic noise doesn’t allow to allocate the video frame, reduces its clearness and increases security of video signal in proportion to the relation of a root square number of the video frames to number of changes of a video noise frame.
