摘要
The invention relates to a digital signal formed by a plurality of subcarriers, and intended to be transmitted to at least one receiver, EVENTUALLY simultaneously at least one analog television signal CARRIER HOME VIDEO ISSUED TO A PV FREQUENCY AND PRESENTING A series of lines aNALOG VIDEO corresponding to a line frequency FL, the spacing FREQUENCY intercarrier {DF} between two neighboring subcarriers A submultiple of the frequency LINE FL, one of said subcarriers emitted at a substantially equal FREQUENCY PV + N.FL, where N is an integer, so that a subset of said subcarriers, KNOWN SUBSET OF cOINCIDENCE, coincides substantially with at least some analog VIDEO LINES. ASI, digital subcarriers ARE PLACED, according to the frequency axis, so that a small number of subcarriers (the subset of COINCIDENCE), CLEARLY IDENTIFIED, ARE superimposed signal lines ANALOG AND OTHER subcarriers are substantially disturbed by These lines ANALOGICAS. The invention relates receptors that signal.
