Television programme reception limiter. The television programme reception limiter forming the object of the invention, whose purpose is to prevent the signal(s) of (a) certain television channel(s) being available on a specified receiver, by means of previous programming/coding by the user at specified periods of time, will enable the reception of pre-set programmes to be controlled. For control, the user has a programmer/switch 7 and a coding circuit or element 8 by means of which a set of relays 6 is activated that allow the passage of signals originating from a bank of filters 5, 5', 5". or from the group of modulators 11, 11', 11". depending on the design chosen, so that the output signal 10 to be input into the appropriate receiver is formed via an adder/amplifier 9. <IMAGE>
