  • Group based search engine generating search results ranking based on at least one nomination previously made by member of the user group where nomination system is independent from visitation system
    Patent number: 6947924
    Abstract: A search system and method for performing group-based searches. The system comprises a client system having a browser and a search engine plug-in, wherein the search engine plug-in allows group members to generate nomination data by nominating web pages; and a server having a control program and a group structure for storing nomination data, wherein the control program generates a primary search result list based on a search index, and further refines the search result list based on the stored nomination data.

  • Method and apparatus for detecting and controlling data stream splicing in ATM networks
    Patent number: 6067303
    Abstract: A method and apparatus are provided for detecting and controlling data stream splicing in a stream of multimedia digital data over a distribution communications network. Sequential transport stream packets are obtained. Predetermined fields of each transport stream packet are interrogated to identify a splice in the data stream. A predetermined task is initiated responsive to an identified splice. In accordance with feature of the invention, one predetermined task initiated responsive to the identified splice includes masking the interrogated predetermined fields to mask the splice in the data stream.

  • Earliest deadline first communications cell scheduler and scheduling method for transmitting earliest deadline cells first
    Patent number: 6028843
    Abstract: A method and apparatus are provided for scheduling the transmission of cells of a plurality of data streams in a communications network. An earliest deadline first (EDF) scheduler is provided for scheduling the transmission of cells of a plurality of data streams in a communications network to ensure that the connection or data stream with the earliest deadline is transmitted first. Each of the multiple data streams has a delay bound or deadline. Data of each data stream is enqueued to a corresponding data cell queue. A timing wheel time slot based on an identified target transmission time for each data cell queue is calculated utilizing an addition of a maximum delay value. A move forward timing mechanism includes a scan forward feature to identify a succession of virtual connection or data stream cell queues for transmission. A multiple tier cell scheduler is provided that includes at least two scheduling timing wheels.
