Beschreibung
Zusammenfassung:	FIELD: methods of processing of television signals. SUBSTANCE: video signal brightness portion, which before recording is "rolled in" near carrier frequency, after reproduction is restored and applied in parallel to horizontal and vertical comb filters, whose combined output signal actuates not fully eliminated horizontal and vertical ROLLING frequency components. Device of the vertical and horizontal band edge detector receives the restored rolled in video signal, which changes the proportions of output video signals of the horizontal and vertical comb filters in combined video signal. EFFECT: enhanced quality of video signals. 7 cl, 6 dwgi
