Abstract: The disclosure relates to modem and router modules for use with digital display systems, including televisions. A modem module is configurable to attach to a set-top box, a set-back box, directly to a digital display, or may even be integrated into display equipment. Router functions and ports can be integrated into the module to provide for networking of additional devices in proximity to the module and/or display, using either or both wired and wireless access technologies. Systems including the module convert power to the appropriate forms for delivery to the different devices, hardware, and components associated with the module. The modem and routing functions are configurable to provide separate security domains to isolate or direct traffic among the various networked devices.

Abstract: The disclosure relates to content delivery systems such as gateways for use in locations where the services of many end user devices are provided by a common management entity, such as hospitality, dormitory, healthcare, or other enterprise settings. The disclosure includes methods of initializing a gateway configuration and operating a gateway by ingesting content from a variety of signals (satellite, broadcast, cable, and IP), processing the content to have additional desired features, and reassembling content in various forms for delivery to individual end user devices.

Abstract: The disclosure relates to content delivery systems such as gateways for use in locations where the services of many end user devices are provided by a common management entity, such as hospitality, dormitory, healthcare, or other enterprise settings. The disclosure includes a gateway system that is configurable to ingest content from a variety of signals (satellite, broadcast, cable, and IP), process the content to have additional desired features, and reassemble content in various forms for delivery to individual end user devices. The gateway can be constructed from a series of modular processing blades with specific processing functions all interconnected by a common backplane and managed by a control module. A gateway can be inserted downstream from a node to allow additional end units to be added without exceeding the node capacity.

Abstract: Television signal scrambling is effected by combining moderate level trap-attenuation of the visual carrier frequency with an injected fm-modulated interfering signal to effect, by adjustment of amplitude and fm-modulation levels, satisfactory picture scrambling and overpowering audio distortion in the user's television receiver.

Abstract: Television or similar picture scrambling or the like wherein narrow trapping of the visual carrier is effected with one-direction FSK-FM modulated wobbulation of the visual carrier, preferably alternately at different multiples of the horizontal synchronizing frequency.

Abstract: This disclosure is concerned with a limited time operative decoder for special scrambled television program transmissions involving a voltage source for energizing the decoder of limited time effectiveness adapted to energize the decoder only during the limited time of the special scrambled television program.

Abstract: This disclosure is concerned with an improved special program addressable subscription decoding technique in accordance with which ordinary program subscribing decoders continue to receive and decode the scrambled flat rate programs to which they are entitled while being disabled from receiving any of a plurality of special scrambled programs associated with a different control signal that will only enable decoding after pre-set unique address verification has been transmitted, checked and introduced into memory indicative of subscription to particular of such special programs, whereby the special program decoding will be effected compatibly with the continued flat rate program decoding by ordinary program subscribers.

Abstract: This disclosure is concerned with a linear antenna array mounted on a conductive longitudinal boom, as in a Yagi-type array or the like, having a plurality of assymmetrical transversely extending folded half dipoles and linear extensions thereof disposed at successive longitudinally spaced locations along the boom, with the folded half dipoles of successive antennas extending from opposite sides of said boom.

Abstract: This disclosure is concerned with simplification of customer TV decoders for scrambled television signals fed from a master antenna system or the like, by novel head-end decoding and simultaneous scrambled STV transmission along the distribution cable to the user TV sets.

Abstract: This disclosure is concerned with modulating the tuning of a picture carrier frequency trap to insure audible distortion of the sound signal in a subscriber television system irrespective of variations in circuit parameters caused by temperature or other changing tuning adjustments of the trap.

Abstract: A novel grid-type corner reflector adapted to direct circularly polarized waves is described, involving critical and uneven grid reflector rod spacings and fed dipole tilt angles, with adaptation for circular passive directors, as well.

Abstract: This disclosure is concerned with compensating for unsymmetrical antenna receiving or transmitting patterns caused by unbalanced driven element feed, by compensatory unsymmetrical interaction with parasitic director and/or reflector elements.

Abstract: This disclosure is concerned with simplified decoder apparatus for use with depressed horizontal sync scrambled television transmissions, embodying intercarrier detection of picture and sound carriers and FM demodulation of audio information including a pilot tone used to restore the video sync signal by controlling an RF gating amplifier.

Abstract: This disclosure deals with a novel scrambled television decoding system for modulation-suppressed trains of synchronizing signals at a predetermined line rate, in which the demodulating circuits produce an advanced modulation frequency signal synchronized with a selected reference first equalizing pulse to control the gain of the received scrambled television signals and correspondingly to restore the suppressed synchronizing signals to reconstitute the unscrambled television signal.
