Abstract: The integration of gateway services such as, but not limited to, one or none of Network Address Translation (NAT), firewalls, proxies, tunneling, and/or Virtual Private Networking (VPN) into RF cable devices such as, but not limited to, cable modems and/or set-top boxes advantageously provides additional capabilities for accessing the internet over an RF cable connection.

Abstract: A method and apparatus for providing periodic subscription television services comprises a way for subscribers who cannot afford the fees for full time television services such as a regular cable television service to obtain subscription service to a plurality of allocated channels on a periodic basis. The method comprises the steps of allocating channels to a periodic service offering and storing in memory of service denial apparatus service code data which represents the allocated channels. The service denial apparatus for providing periodic service comprises a service denial device such as a switch 389 or other circuit controlled by a controller 260 of service denial apparatus for periodically closing and opening service lines to the periodic service subscriber in accordance with predetermined periodic service intervals.

Abstract: Off-premises cable television pay per view apparatus 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. A radio frequency transmitter is coupled between a controller and the upstream diplexer which may actuate a selected one of a plurality of data channels in the notoriously noisy subsplit 5-30 megahertz transmission spectrum for reporting billable events. On-premises equipment is minimized to comprise only a unidirectional data transmitter. The data transmission is sent repetitively over a predetermined period of time before the data transmitter, comprising a microprocessor, turns itself off to conserve power.

Abstract: An off-premises method and apparatus for the interdiction of unauthorized channels of a broadband cable television signal includes common circuitry for adjusting the amplitude and equalization levels of the broadband CATV signals and one or more subscriber modules for generating jamming signals of different frequencies which are used to interdict one or more unauthorized channels. Each subscriber module is associated with a subscriber and is programmable and addressable to adjust the jamming parameters of that subscriber independently of other subscribers. Each subscriber module circuit comprises a plurality of latches, each of which is associated with one of a plurality of digital to analog converters. Each of the digital to analog converters drives one or more frequency agile oscillators with its analog output to generate the jamming signals.

Abstract: An off premises CATV system is disclosed. A headend transmits programming including pay-per-view programming and a cable distribution system distributes the programming. An off premises unit is coupled to the cable distribution system for supplying the programming to at least one subscriber. A subscriber terminal is coupled to the off premises unit over a communication link. The subscriber terminal including an input device for inputting subscriber-supplied signals indicative of a pay-per-view event to generate a message. A transmitter responsive to the subscriber-supplied signals transmits the message to the off premises unit over the communication link. The message is transmitted at a plurality of random times within a predetermined period of time.
