An IP video delivery system and method that allocates a first number of video streams for delivery on a number of channels that, provides a number of bonding groups, where each bonding group bonds at least one of the channels, and allocates a second number of video streams for delivery on the bonding groups. In one aspect, the method delivers the first video streams as unbonded on the channels. The bonding groups utilize bandwidth unused by the first video streams. In one aspect, the method utilizes bandwidth unused by the first or second video streams for high speed data. The method provides instantaneous load balancing to spread the first and second video streams across all available bandwidth in the channels, and delivers those video streams using a variable bit rate with no additional statistical multiplexing rate shaping to fit video streams into the channels.

A service convergence fabric () is operably disposed between a plurality of independent access networks, control networks, and service networks () and a converged application layer (). This service convergence fabric is then used () to receive a service request, process the service request, provide a corresponding response, and publish that response to facilitate the service request. Processing the service request can comprise processing the service request with respect to resources to support the service request, user session status as corresponds to the service request, and user preferences as correspond to the service request. Providing a response can comprise providing a response that comprises at least one of a processed service request and a converged response to the service request.

In a cable television system a system for supporting SCU return in FTTB-MDU and FTTC/FTTcab configurations. Fiber, baseband transceiver and networking capabilities are shared with data and voice portions of the system for enabling communication from the SCUs to the HE over a packet based networking system. Return packets/upstream packets are passed into the network upstream channel only when a signal is present for eliminating transmission of upstream traffic that contains no signal for conserving upstream bandwidth.

System for return bandwidth minimization using selective sampling

First location information related to a location-aware device () is gathered. Second location information for a location-unaware device () is determined from the first location information. A data structure is created comprising a binding of the second location information and an identifying parameter of the location-unaware device (). The data structure is provided in a form usable by an application.

System and method for providing location information to applications

In a PCM modem system in which equivalence classes are used to communicate information from a transmitter to a receiver, a method is provided to solve the problem of 180&deg; phase reversals in the communications channel which result in a garbled transmission. This is accomplished by remapping the equivalence classes into a form that can be differentially encoded and decoded such that equivalence class identity is not lost during a phase reversal of the channel.

Method and apparatus for achieving 180&deg; phase invariant transmission in a PCM modem system

A system and method for shifting the relative phases of a PCM data frame and a network RBS frame by one or more symbols is disclosed. The method includes determining whether or not RBS is present. If RBS is present, the slots affected by RBS are identified. Next it is determined what data slots, if any, are affected by encoding. The PCM data frame is shifted so the RBS constraint and the encoding constraint do not coincide at any particular data slot. For one particular PCM upstream modulation scheme, the digital modem adjusts the relative phases of the data-mode frame and network RBS frame such that a minimum number of trellis-modified symbols fall on network RBS affected slots. This information is transmitted to an analog modem. The amount of shift can be conveyed to an analog modem in the same data sequence used to send upstream constellation sets and mapping parameters during an initial training sequence. The present invention improves the performance of any PCM modem that employs a data frame structure in which not all symbols are subject to the same constraints, for example, due to trellis coding.
