Abstract: A system and method for guaranteeing an upper bound on output jitter while maintaining maximum loop bandwidth. At least a portion of a plurality of transport packets stored in a buffer include a first timestamp value. A first phase locked loop receives a stream of first timestamp values and generates a variable rate timing signal stream that conveys a variation rate and a phase accumulation rate of the stream of first timestamp values to the first loop. A second phase locked loop receives the variable rate timing signal stream and generates a stable rate timing signal stream conveying the average rate of the variable rate timing signal stream. A interval timer is responsive to the stable rate timing signal stream in order to release the transport packets from the buffer.

Abstract: A Digital Home Communication Terminal (DHCT) including a plurality of tuners, each of which can select one of a plurality of transmission channels provided by a Digital Broadband Delivery System (DBDS). The multiple tuners enable the DHCT to tune to a plurality of downstream media and data transmissions, thereby allowing a subscriber to tune simultaneously to multiple channels and content transmitted in the downstream transmission via the DBDS, an advantage over conventional DHCTs. The present invention enables subscribers to receive and view multiple channels and associated content, including electronic program guide information, at will. Furthermore, using the multiple-tuner DHCT of the present invention, subscribers can view multiple television stations and program content simultaneously, without degradation to television signals or pictures.

Abstract: 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 have 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. The architecture generally can be used to support connection-oriented physical layer connectivity between a remote device and the central concentrator.

Abstract: The present invention comprises customizable, multimedia messaging over a subscriber television system, such as a cable or satellite system, utilizing a service independent framework. The present invention comprises a multimedia messaging (MMM) server generally located at a headend of a cable or satellite system, and an MMM client at a communications terminal located remotely with respect to the MMM server. A service provider or operator defines a message configuration that is utilized to present the message content to one or more subscribers. The message configuration includes parameters that control the presentation of the message content. The MMM server receives an MMM request from a service application, and in response thereto, generates an MMM request which is sent to the communications terminal, and more particularly, to the MMM client. The MMM client processes the MMM request, including the retrieval of any message content or the message configuration.
