Abstract: A circuit board connectable RF relay that is comprised of a metal housing; a first RF signal input/output means; a second RF signal input/output means, wherein there is a cavity in the top portion of the metal housing called the upper cavity and a cavity in the bottom portion of the metal housing called the lower cavity, wherein there is an aperture in the top end of the upper cavity and the first RF signal input/output means is located in the upper cavity such that its first end is continuous with the aperture and its second end is continuous with the lower cavity, and wherein the second RF signal input/output means is located in the lower cavity such that its first end extends beyond the bottom of the metal housing and its second end is situated farther within the lower cavity such that it is not in direct conductive contact with the second end of the first RF signal input/output means, and an impedance loading contact, and an RF signal connection means having control signal inputs and a conductive moveable

Abstract: A frequency generating means, generates an initial frequency of greater amplitude than the amplitude of a television signal carrier wave. The generated frequency is compared to a reference frequency which would be suitable for jamming one of the channels to be jammed. If the generated frequency is too high or too low, the frequency generating means generates a new frequency which is, respectively, either lower or higher than the initial frequency it generated. If the new generated frequency is still higher or lower than the reference frequency, the frequency generating means generates another new frequency, which is respectively, either lower or higher than the previously generated frequency, but by a lesser amount than the amount by which the previously generated frequency differed from the frequency generated before it. The generation of new frequencies continues until one of them is within a desired range of the reference frequency, at which time the generated frequency is stored in memory.

Abstract: A method and apparatus, for jamming selected channels, in a CATV system, wherein six different pre-determined frequencies ("fx"), are generated at a head end, on a time divisional basis, which head end also generates a synchrinization signal ("sync. sig.") that identifies which fx is being generated, a multiple of receiver ends, each of which receives, at one input all of the TV channels' signals, the fx, the sync. sig., and a subscriber status signal ("SSS") that identifies the channels, if any, that the subscriber is entitled to receive, wherein the receiver end: (A) divides the received signals into: (I) TV channels' signals, SSS, and sync. sig., and (II) fx; (B) generates a local fixed frequency; (C) mixes the local fixed frequency with the fx, thereby creating a jamming signal; (D) decodes the sync. sig.

Abstract: Multiple latching relays are driven on their first side by all but one of the parallel outputs of a shift register. Each relay on the same shift register is driven on its second side by the remaining parallel output of the shift register. A clock signal is fed to all shift registers and causes each shift register to shift all of its information one cell on the selected edge of the clock signal. A latch signal or blanking signal is used to prevent the shift registers from outputting their information to the relays during shifting. A serial data message is inputted to the first shift register and then from the first shift register sequentially to all of the other shift registers. The information in the serial data message is such that after shifting of all shift registers is complete the appropriate signal will be on each side of each latching relay to cause it to either change or remain unchanged.

Abstract: In order to selectively jam M selected channels to selected subscribers in a CATV system, each of M different oscillating signals, each of which oscillating signals has a duration longer than the duration of the horizontal synchronization signal of the television channel it is to jam and a frequency higher than the carrier wave of the channel it is to jam, are in turn added to the television signal circuits of those subscribers who are not authorized to receive the particular channel being jammed by the jamming signal being added. The television set of the non-authorized subscriber picks up the higher frequency jamming signal as the valid horizontal synchronization signal and therefore ignores the valid horizontal synchronization signal, with the result that the channel in question is unviewable on the television set of the non-authorized subscriber.
