  • Patent number: 5920802
    Abstract: A video distribution system with an optical-to-radio frequency conversion device that can be configured to reduce the amount of insertion loss introduced into the system and the number of hardware connections needed for the system's operation. A jumper module replaces protection fuses within the conversion device and isolates two of the device's output signal ports from the internal low frequency supply used to operated the device. The isolation permits the use of a single power inserter apparatus that provides the electrical power to downstream signal driving devices receiving the converted signal from the device.

  • Patent number: 5479202
    Abstract: A network interface module operably connected to a subscriber's television receiver and to a switched broadband digital network includes a fiber-compatible digital transceiver. A downlink receiver in the transceiver detects video/audio/data information that is time-multiplexed within a serially transmitted digital signal optically transmitted by the switched digital network as a broadband digital downlink channel. The detected information is decoded into a parallel format of video/data samples, audio samples, and recovered sample clock that are applied to a digital switch in the television receiver.

  • Patent number: 4789895
    Abstract: A telecommunication system for synchronizing a digital bit stream sent from a central facility to a terminal on lines of television frames. Each active line starts with a horizontal sync pulse and a color burst. A first data clock at the central facility provides first data clock pulses synchronized with said color burst. A circuit at the central facility provides a flag bit one clock pulse wide delayed by a first constant number of clock pulses from the start of the line's horizontal sync pulse. A second data clock at the terminal provides second data clock pulses synchronized with said color burst. A circuit at said terminal provides a time window delayed by a second constant number of clock pulses from the start of the line's horizontal sync pulse so as to bracket said flag bit. A plurality of second data clock pulses occur during said time window.

  • Patent number: 4780757
    Abstract: A telecommunication system has a facility and an addressable terminal coupled through a transmission medium. The facility includes means for providing addressed video frames containing information corresponding to still images and for providing addressed audio frames containing information corresponding to audio bursts. There is also provided for non-addressed signals containing information corresponding to at least two channels of continuous audio. A selection code is inserted in one or more of the frames. The addressed video and audio frames and non-addressed signals are coupled to the transmission medium to the addressable terminal. The terminal has means for detecting said addressed video frames, addressed audio frames, and non-addressed signals. Circuits select video frames and audio frames in response to their corresponding addresses. One of said continuous audio channels is selected in response to said selection code.

  • Patent number: 4780758
    Abstract: A telecommunication system for transmitting video and plural audio information on a transmission medium includes a facility and an addressable terminal. The facility includes arrangements for providing addressed video frames containing information corresponding to still images and for providing addressed audio frames containing information corresponding to audio bursts. There is also means for providing non-addressed signals containing information corresponding to at least one channel of continuous audio. The addressed video frames, addressed audio frames, and non-addressed signals are coupled to the transmission medium and sent to the terminal. The addressable terminal includes means for detecting said addressed video frames, addressed audio frames, and non-addressed signals on said transmission medium. Circuits select video frames and audio frames in response to their corresponding addresses.
