摘要:
A receiver at a node in an optical network receives an optical clock signal and an OTDM datastream. A detector converts the clock signal to the electrical domain. A variable delay stage applies a selected delay to the clock signal in the electrical domain. A non-linear electro-optic modulator which may be an electro-absorption modulator, receives the OTDM datastream at its optical input. An electrical control input of the modulator is connected to the output of the variable delay stage. The electro-optic modulator outputs an OTDM channel selected by setting the delay of the variable delay stage. The variable delay stage may include a number of logic gates, particularly AND gates, connected between a pair of microstrip delay lines. The gates are controlled to provide different paths with different corresponding delay times for the clock signal.

An optical pulse source includes a gain-switched semiconductor laser diode (1). Light from a continuous wave source (3) is optically coupled into the laser cavity. Light output from the laser cavity passes through an electro-optic amplitude modulator (2). Synchronised modulating signals are applied to the semiconductor diode and to the amplitude modulator. The source outputs short low-jitter optical pulses and is suitable for use, for example, in a broadband optical network operating at high bit rates of 100 Gbit/s or more, or in an optical interconnect.

A system and method allow a user or business entity to create customized rules for bidding on keywords to/from a search engine. A bid automation engine allows a user or business entity to specify a number of rules for bidding on keywords used in Internet advertising campaigns. The bid automation engine may be part of, or interface with, a web analytics tool and/or a bid management system to provide user-defined strategies for bidding on keywords. Accordingly, a user or business entity may set up a customized bidding strategy for keywords by building sets of bidding rules.

A method for generating and maintaining hierarchical tags with community-based ratings is provided. Tags for media streams are organized into a hierarchical format. Users may select tags from the hierarchical tag database that describes a particular multimedia content. If the user is unable to locate a desired tag, the user may submit a new tag. Upon submission of the new tag, a librarian approves the tag before storing and placing the tag in the hierarchical tag database. Users are also able to rate the quality of the association between the tag and the multimedia content. If a tag is rated low, the tag may be removed from the hierarchical tag database. If the tag is rated highly, display of the tag in a list of tags becomes more prominent.

A system and method for deploying and managing software components to a plurality of network devices of an extended data communications network. In one embodiment of the invention, a client type defining software components required for at least one network device of the plurality of network devices may be determined. At least one network device of the plurality of network devices corresponding to the client type may be determined. The software components may be provided to the at least one network device based in part on the client type. The software components may be installed on the at least one network device such that functional capabilities of the software components may be employed by the network device. In another embodiment, a record of the software components installed on the at least one network device on a hub server associated with the extended data communications network may be stored.

A method of rendering content on a wireless device. The wireless device sends a message to a server requesting an application and identifies itself with its rendering capabilities. The wireless receives an identification of a custom configuration of a plurality of rendering blocks of the wireless device associated with the application. The custom configuration configures the plurality of rendering blocks of the device. The wireless device receives compiled content from the application executing on the server that includes render commands expressed in a syntax that is device generic but has parameters specific to the rendering capabilities of the wireless device. A reader of the wireless device processes the compiled content and issues commands to individual rendering blocks of a graphical user interface based on the rendering commands of the compiled content and based on the custom configuration.

摘要:
A closed caption tagging system provides a mechanism for inserting tags into an audio or video television broadcast stream prior to or at the time of transmission. The receiver receives the broadcast stream and detects and processes the tags within the broadcast stream which is stored on a storage device that resides on the receiver. The tags contain command and control information that the receiver translates and acts upon. A one-touch recording option is provided. An icon is displayed to the viewer telling the viewer that an advertised program is available for recording at a future time. The viewer presses a single button on an input device causing the receiver to schedule the program for recording.
