Patent number: 8363679Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of Ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Furthermore, the architecture allows a central concentrator to support a plurality of remote devices that each has guaranteed bandwidth through connection-oriented allocations of bi-directional data flows. The upstream and downstream bandwidth allocation can support symmetrical bandwidth as well as asymmetrical bandwidth in either direction. As a local network, the architecture supports guaranteed bandwidth for delivery of data flows to a plurality of host devices.Type: GrantFiled: April 13, 2009Date of Patent: January 29, 2013Inventors: Donald C.

Patent number: 7519081Abstract: Disclosed herein are methods of providing a client with local area network connectivity and access to other services in a cable network. One such method includes: allocating bandwidth in the network to support bi-directional data communication between the host and a central concentrator. Bandwidth is allocated for a downstream flow on at least one downstream frequency channel based on a mapping between the downstream flow and a particular octet in a downstream packet. Bandwidth is allocated for an upstream flow on at least one non-shared upstream tone. The method also includes conveying a bi-directional data flow between the host and the concentrator over the allocated bandwidth, including conveying the upstream flow using the allocated bandwidth and conveying the downstream flow using the allocated bandwidth. The method also includes utilizing bandwidth in the network not allocated to data communications to provide the host with at least one audio/visual service.Type: GrantFiled: September 17, 2002Date of Patent: April 14, 2009Assignee: Cisco Technology, Inc.Inventors: Donald C.

Patent number: 7218901Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Moreover, an automatic frequency control resolves some issues of a free-running clock in an upstream tuner of the central concentrator by performing adjustments based on the average frequency error of a number of active upstream tones. In the preferred embodiments of the present invention, the automatic frequency control (AFC) utilizes a feedback loop for at least each active upstream tone. Also, the average of the active upstream tones is determined and is utilized in providing feedback to adjust the automatic frequency control (AFC).Type: GrantFiled: September 17, 2002Date of Patent: May 15, 2007Assignee: Scientific-Atlanta, Inc.Inventors: Joseph Graham Mobley, Jiening Ao, Steven E.

Patent number: 6567987Abstract: A cable television system (400) includes a transmitter (200) for generating a digital optical signal (204) and a receiver (300) for receiving said digital optical signal and converting it to an analog signal. The transmitter (200) includes a processor (238) for processing inputs and generating a gain/loss parameter which is applied via a gain/loss amplifier (250) to an incoming analog signal (232). The modified digital signal received by the digital optical receiver (300) decodes the applied gain/loss parameter at a converter (325) and applies the information to the output analog signal via a gain/loss amplifier (330).Type: GrantFiled: February 16, 1999Date of Patent: May 20, 2003Assignee: Scientific-Atlanta, Inc.Inventors: Forrest M.

Allocation of bit streams for communication over-multi-carrier frequency-division multiplexing (FDM)
Publication number: 20030053493Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Also, the modulation indices of various upstream frequency channels may be different, but a plurality of upstream channels may be used to carry a single data flow generally in parallel. The upstream data flow is fragmented into blocks and formed into superframes to allow transmission over at least one upstream frequency channel. When a plurality of upstream frequency channels are utilized, the superframes facilitate the possibility of having different modulation indices on the plurality of frequency channels.Type: ApplicationFiled: September 17, 2002Publication date: March 20, 2003Inventors: Joseph Graham Mobley, Jiening Ao, John A.

Patent number: 6437895Abstract: A cable television system (100) includes forward and reverse paths. In the reverse path, an optical transmitter (405), which could be located in an optical node (115), receives an analog information signal from subscriber equipment (130) and transmits in accordance therewith a digital optical signal. The optical transmitter (405) digitizes its incoming signal, compresses the signal, and generates therefrom the digital optical signal. The cable television system (100) also includes an optical receiver (500) for receiving the digital optical signal, decompressing information included in digital optical signal, and recovering therefrom an analog signal representative of the analog information signal. The optical receiver (500) could be included in a hub or headend equipment (105) of the cable television system (100).Type: GrantFiled: April 5, 1999Date of Patent: August 20, 2002Assignee: Scientific-Atlanta, Inc.Inventors: Forrest M.

Patent number: 4100472Abstract: A satellite tracking antenna system for use on board ship as part of a maritime communications satellite terminal is disclosed. The system has a directional antenna which is continually trained in the direction of the satellite so as to receive signals therefrom and transmit thereto in spite of the continual rolling, pitching and turning movement of the ship as it travels along its course, even in heavy seas. The system includes a platform which is adapted to be mounted at the head of the mast of the ship. A servo control unit receives position and angular rate signals from roll and pitch sensors mounted on the platform, and serves to counteract pitch and roll without the need for gyroscopic stabilization means so that the platform always remains level regardless of the pitching and rolling of the ship. A structure including the antenna, is mounted on the platform for rotation in azimuth and elevation.Type: GrantFiled: August 19, 1976Date of Patent: July 11, 1978Assignee: Scientific-Atlanta, Inc.Inventor: Joseph Graham Mobley
