Abstract

Improvements in apparatuses for processing television video signals, of the type comprising luminance signal compounds, chrominance and color impulse, the apparatus comprising a source of video signals, signal delay means coupled with said source of video signals, a plurality of signal coupling means coupled with said signal delay means for developing a plurality of delayed video signals, first means for combining at least a first and a second one of said video signal delayed or separated in the time in a range practically equal to nt/2 where t is the period of a previously chosen signal component supplied by said source and n is an integer greater than one, to produce a first combined signal, means to derive a determinant signal from the bandwidth from at least one third of said delayed video signals located at the time said first and second delayed video signals, second means for combining said bandwidth determining signal and the first combined signal to produce a second combined signal, characterized in that means are provided to derive a control signal from a certain part. Of said video signals, means for controlling the amplitude of the second combined signal in accordance with the control signal and producing a resulting signal and third means for deriving an output signal from at least the resulting signal.
