FIELD: TV equipment. SUBSTANCE: first complex video signal has ghosts and consists of, at least alternating periods in given L-th line of each field within interval of vertical blanking. These periods belong to cycle of M ghost black-out reference signals of given level and respectively phase, where M is integer, which is greater than one. Filter circuit generates second complex video signal depending on first complex output signal, which characteristic is controlled by filter programming signal, which is generated by computer, which stores it in its memory in association with ghost black-out reference signal this signal which is free of ghosts. Computer is used for receiving ghost black-out reference signal with respective ghosts. Computer compares this signal to ghost black-out reference signal which is free of ghosts and stored in computer memory in association with it during conducting correlation operations which serve as basis for calculation of filter programming signals. Filter programming signals are calculated so that second complex video signal is response from output of first complex video signal, in which corresponding ghosts are significantly reduced. Field counter counts separated vertical synchronization pulses by modulo M and generates field count, which synchronized in cycle of M ghost black-out reference signals. Time filter combines M N serial scanning lines which are separated by L-th line separator in order to achieve time filter response, which is sent to computer as reduced noise ghost black-out reference signal with respective ghosts, where N is positive integer. EFFECT: increased efficiency of ghost blanking. 12 cl, 5 dwg
