    Abstract: Set top boxes (STBs) connected to the HFC cable network are “pinged” and their responses recorded. The two most responsive STBs in each node of the HFC cable network are identified. The most responsive STB is added to a primary ping list and the next most responsive STB is added to a secondary ping list. The STBs on the primary list are “pinged” and their responses recorded. If an STB on the primary list fails to respond, the secondary STB associated with the node is pinged. If both the primary and secondary STB associated with a node fail to respond to the “ping,” the node is identified as non-responsive. If all of the nodes associated with a modulator (or a demodulator) are identified as non-responsive, the modulator (or demodulator) is identified as “non-responsive.” Additionally, network devices are pinged and their responses noted. Using the responsiveness of nodes and network devices, faults in segments in an HFC cable network can be identified and located.

    Abstract: A system and method for identifying and isolating faults in a video on demand (VOD) provisioning system. Transaction errors statistics are used to determine whether a fault has occurred in the VOD provisioning system. A high transaction error rate is associated with transaction error rates in components of the VOD provisioning system permitting identification of a likely cause of a high transaction error rate. Remedial action to repair the cause of the system fault is then directed to the likely cause of the high transaction error rate.

    Abstract: A system is disclosed including a transmitter and receiver for the communication of security codes which may be validated at the receiver to operate equipment. In one embodiment, the transmitter transmits a security code at two frequencies contemporaneously to the receiver which may receive both frequencies and resolve the security code therefrom. The receiver may lock onto one frequency to the exclusion of the other frequency when parts of a security code are detected. In another embodiment, the transmitter selectively transmits security codes at a default frequency which is selected because of a recorded count of prior apparent successful transmission

    Abstract: A data-driven, hierarchical information navigation system and method enable search of sets of documents or other materials by certain common attributes that characterize the materials. The invention includes several aspects of a data-driven, hierarchical navigation system that employs this navigation mode. The navigation system of the present invention includes features of an interface, a knowledge base and a taxonomy definition process and a classification process for generating the knowledge base, a graph-based navigable data structure and method for generating the data structure, World Wide Web-based applications of the system, and methods of implementing the system. Users are able to search or browse a particular collection of documents by selecting desired values for the attributes. A data-driven, hierarchical information navigation system and method enable this navigation mode by associating terms with the materials, defining a set of hierarchical relationships among the terms, and providing a guided search mechanism based on the relationship between the terms.
