US Patent:

51092867, Apr 28, 1992

Filed:

Dec 6, 1989

Appl. No.:

7/446695

Inventors:

Lamar E. West - Maysville GA
James O. Farmer - Lilburn GA

Assignee:

Scientific-Atlanta, Inc. - Atlanta GA

International Classification:

H04N 7167

US Classification:

358349

Abstract:

A cable television reverse manifold system is coupled between first and second diplexers of off-premises subscriber service providing equipment. The diplexers separate the transmission path between a headend and a subscriber into downstream or forward and upstream or reverse transmission paths. In one embodiment, the reverse manifold apparatus combines signals from at least one subscriber for transmission to the headend. In another embodiment including a data receiver and a controller, the off premises service providing equipment may be controlled by the subscriber. In yet a third embodiment, a radio frequency transmitter is coupled between the controller and the upstream diplexer which may actuate a plurality of simultaneous data transmissions over separate data channels in the notoriously noisy subsplit 5-30 megahertz transmission spectrum.

International Classification:

H04N 7167

US Classification:

380 7

Abstract:

Off premises cable television interdiction apparatus comprises a microprocessor actuation and control means for actuating and controlling one or more frequency agile voltage controlled oscillators. The voltage controlled oscillators selectively jam only unauthorized premium programming transmitted in the clear from a headend to a particular subscriber. Each voltage controlled oscillator is allocated a continuous band of frequencies consistent with the elimination of jamming signal frequency harmonics which may disturb authorized programming at a higher channel frequency. The microprocessor actuation and control means provides a calibration mode and a normal mode of operation. The method of interdiction comprises the steps of generating and storing voltage control words for operating the oscillators consistent with a head end selected jamming factor for a particular channel to be jammed and addressably transmitted and stored premium programming authorization data. An optimum frequency amplitude window for the jamming signal is disclosed.

The voltage controlled oscillators selectively jam only unauthorized premium programming transmitted in the clear from a headend to a particular subscriber. Each voltage controlled oscillator is allocated a continuous band of frequencies consistent with the elimination of jamming signal frequency harmonics which may disturb authorized programming at a higher channel frequency. The microprocessor actuation and control means provides a calibration mode and a normal mode of operation. During the normal mode of operation, a frequency hopping rate on the order of four thousand hertz is achievable. The method of interdiction comprises the steps of generating and storing voltage control words for operating the oscillators consistent with a head end selected jamming factor for a particular channel to be jammed and addressably transmitted and stored premium programming authorization data.
