  • Patent number: 9055030
    Abstract: Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, a system that monitors telemetry information may include a user that gathers telemetry information of a device and transmits the information to a monitored room. A manager may join a monitored room and monitor the monitored room for particular types of telemetry information. In one example, a manager may determine whether a downstream device is experiencing a network problem, such as a low bitrate. A manager may also transmit commands to the player via the monitored room, which causes the downstream device to operate in accordance with the transmitted command. In one example, a manager may transmit a command that causes a player to decode a particular service.

  • Publication number: 20130198401
    Abstract: A method of data conditioning is disclosed that in one aspect can include the steps of receiving a data stream, encoding a time code in the data stream to identify a portion of the data stream corresponding to a content fragment, and separating the identified portion of the data stream to define the content fragment, wherein the content fragment comprises the encoded time code.

  • Publication number: 20130173817
    Abstract: Some aspects of the disclosure relate to transmitting content over a network. For example, a device may determine that it is missing a content fragment from its cache, and may send a request for the content fragment. A network device may be configured to respond to such requests by transmitting the content fragment. In some instances, this may allow receiving devices to acquire the missing content fragment without the need to transmit a request for content.

  • Publication number: 20130138795
    Abstract: Transaction activity of a cache maintaining content may be monitored to determine periods of transaction activity below a first threshold amount of transactions. A period of anticipated transaction activity above a second threshold amount of transactions may be determined. A period of anticipated transaction activity below the first threshold may be selected based upon the monitored periods of transaction activity below the first threshold and the determined period of anticipated transaction activity above the second threshold. Content then may be evicted from the cache during the selected period of anticipated transaction activity.

  • Publication number: 20130041972
    Abstract: An announcement protocol may allow disparate, and previously incompatible, content delivery network caches to exchange information and cache content for one another. Announcement data may be stored by the respective caches, and used to determine whether a cache is able to service an incoming request. URL prefixes may be included in the announcements to identify the content, and longest-match lookups may be used to help determine a secondary option when a first cache determines that it lacks a requested content.

  • Publication number: 20120304205
    Abstract: A monitoring and analysis system is disclosed that gathers and analyzes information about distributed enhanced content delivery to end user or other equipment. The system may establish communications connections along the content delivery system, filter content received from different locations of the system, and compare the received content with an expected content characteristic. Also, a radio frequency signal from the distribution network may be converted into an Internet Protocol (IP) format by a converter so that the transformed signal may be similarly analyzed as other signals from the system. A report may be consequently generated that is indicative of the received enhanced content and any detected discrepancies with respect to expected enhancement events. Identification of the enhanced content may be based on the program association table and the program map table in order to determine the packet ID of the application signals.

  • Publication number: 20100313230
    Abstract: A content delivery networked is monitored to verify operation of control channels for the delivery of content to a customer. Monitoring includes joining a connection with at least one control channel in the network, decoding content of a signal in the control channel, determining whether the decoded content complies with a pre-determined rule corresponding to content transmitted in the control channel, and producing a report indicating whether the decoded content is compliant with the rule. In addition, a graphical user interface (GUI) displays the status and results of testing the control channel. The GUI is configured to perform generating a display representing testing status of a plurality of DSG tunnels in a first frame and test results of the DSG tunnels in a second frame and providing details of a DSG tunnel test when selected by a user.

  • Patent number: 7196183
    Abstract: The present invention relates to genomic nucleotide sequences and amino acid sequences corresponding to the non-coding and coding region of a new type of HCV. The invention relates to new HCV types and subtypes sequences which are different from the known HCV types and subtypes sequences. Particularly, the present invention relates to said new HCV type sequences; a process for preparing them, and their use for diagnosis, prophylaxis and therapy. More particularly, the present invention provides new type-specific sequences of the 5? NCR, Core, the E1 and the NS5 regions of the new HCV type. These new HCV sequences are useful to diagnose the presence of HCV type genotypes or serotypes in a biological sample. Moreover, the availability of these new type-specific sequences can increase the overall sensitivity of HCV detection and should also prove to be useful for prophylactic and therapeutic purposes.
