  • Patent number: 8825676
    Abstract: A system and method for effectively implementing a personal channel for interactive television comprises a personal channel manager that may include a configuration module, a search module, and a content packaging module. A system user may utilize the configuration module to perform a personal channel configuration procedure to specify personal channel configuration data for performing a content record search procedure. The search module may manage the content record search procedure according to one or more search parameters that may be defined during the personal channel configuration procedure. The search module finds content records from content databases during the foregoing content record search procedure. The content packaging module coordinates a content record sorting procedure according to user-specified sorting criteria.

  • Patent number: 8813153
    Abstract: An intelligent device is configured to receive a DTV signal that includes audio/visual information as well as data signals in a datacast format. The datacast format includes web pages, e.g., in the HTML (hypertext markup language) format of the world wide web. An intelligent filter modifies itself based on user behavior and user preferences in terms of the web pages that a viewer routinely visits. The intelligent filter is then used to identify certain web pages of the pages that are being broadcast and these identified web pages are stored in a cache memory for later use by the viewer. A second tuner can be used to poll multiple channels when updating the cached contents. Cached web pages avoid broadcast latencies (due to periodic updating) and thereby are displayed faster to the viewer.

  • Patent number: 8479245
    Abstract: Embodiments of the present invention are directed to a method of storing digital content in a digital electronic system. In one embodiment, datacast information decoded from a digital media signal is monitored to identify newly-received digital content. The monitoring includes configuring a decoder to receive and decode the datacast information, identifying newly-received digital content from the datacast information, and updating an intelligent filter based upon the newly-received digital content, wherein the intelligent filter records the newly-received digital content. Additionally, the monitoring may include repeating the configuring, identifying, and updating. Thereafter, any of the newly-received digital content that is recorded in the intelligent filter may be stored into a cache memory.

  • Patent number: 7940650
    Abstract: This application describes techniques for peer-agnostic socket replication to implement graceful failover. An exemplary method to enable non-stop routing includes receiving a packet with a first routing engine of a network device having the first routing engine and a second routing engine configured as a backup routing engine, replicating, before processing the packet at a transport layer, the packet to form a replicated packet, sending the replicated packet from the first routing engine to the second routing engine, receiving, at the first routing engine, an acknowledgement from the second routing engine acknowledging reception of the replicated packet, after receiving the acknowledgment, processing the packet at the transport layer of the first routing engine to extract application-layer data and assemble a routing message, and storing the application-layer data from the processed packet in a socket associated with a routing process of the first routing engine.

  • Patent number: 7039929
    Abstract: A client-side intelligent device having background caching of web pages within a digital television (DTV) system and method of same. The present invention includes a digital television system having an intelligent device for interfacing with a user/viewer and controlling the display of information on a display screen. The intelligent device, in one embodiment, is a set-top-box, but could be any intelligent electronic device or computer system. The set-top-box is configured to receive a DTV signal (e.g., land based cable or digital satellite system) that includes audio/visual information as well as data signals in a datacast format. The datacast format includes web pages, e.g., in the HTML (hypertext markup language) format of the world wide web. The DTV broadcasters support multiple channels of information on which content providers can supply a domain of web pages on a periodic basis. The present invention is able to display viewer-selected web pages on the DTV system.

  • Patent number: 6763522
    Abstract: A system and method for providing an electronic program guide for broadcasted digital television wherein the electronic program guide displays only currently broadcasting minor channels, and timely event and contextual information. The system of the present invention includes program code in a memory for causing a tuner/de-multiplexor subsystem to tune to a preselected major channel broadcast frequency and to provide thereby at least one transport stream comprising a plurality of associated digital data elementary streams. The elementary streams include minor channel audio and video, as well as program and system information tables (PSIT), all of which are associated by packet identifiers to provide a table hierarchy. The system of the present invention compares presently broadcasting minor channel and PSIT information with corresponding information in memory.

  • Patent number: 5780582
    Abstract: Hydroxy-functional polyester oligomers are prepared by contacting a hydroxy-functional aliphatic dicarboxylic acid or a mixture of dicarboxylic acids containing hydroxy-functional aliphatic diacids, with a diglycidyl ether or diglycidyl ester in the presence of an onium catalyst in an ether solvent under conditions suitable for forming the oligomer. The oligomers can be used as hot melt adhesives, adhesive tackifiers, plasticizers, heat-curable adhesives and heat-curable coatings. Some of these materials are biodegradable and are therefore suitable for application to compostable end products.
