Patent number: 8230470Abstract: Systems and methods are disclosed for a full duplex wideband communications system for a local (e.g. in-home) coaxial network. The system employs a Frequency-division duplex (FDD) scheme that allows identical wideband modems to communicate with each other. To achieve this, the wideband modems contain a duplexer and a switch that allows reversing the connection of the wideband transmitter and receiver to the duplexer. Each wideband modem includes a control modem that is used to control access to the wideband channels. A wideband transmitter, which may be included in a modem associated with a server set-top terminal (STT), transmits a video presentation to a wideband receiver, which may be included in a modem associated with a client STT.Type: GrantFiled: February 25, 2008Date of Patent: July 24, 2012Inventors: Neil C. Robertson, Jose M. Fernandez

Patent number: 7928883Abstract: Multiple digital signals from a single integrated circuit (IC) may be provided. The IC may receive an analog signal comprising a plurality of channels, convert the analog signal to a digital signal, and provide the digital signal to a plurality of digital channel tuners. The tuners may each select one of the plurality of channels and provide the selected channels as a plurality of digital output signals. A signal conditioner may be used to prepare the analog signal for digitization.Type: GrantFiled: March 13, 2009Date of Patent: April 19, 2011Assignee: Cisco Technology, Inc.Inventors: Neil C.

Patent number: 7908625Abstract: Systems and methods are disclosed for providing downstream signals to a plurality of receiver networks. A receiver network (i.e., a networked multimedia system) includes a splitter/isolation module (SIM), a primary set-top terminal (STT), and at least one remote device. The remote devices communicate with the primary STT via the SIM over coaxial cable. Accordingly, the remote devices utilize some or all of the features including hardware and software that are included in the primary STT via the networked multimedia system.Type: GrantFiled: January 15, 2003Date of Patent: March 15, 2011Inventors: Neil C. Robertson, David B. Lett, Samuel H. Russ, Bohdan S. Prus, Michael A. Gaul, Ajith N. Nair
