  • Publication number: 20160248526
    Abstract: Systems and methods are provided for identifying a video object using digital fingerprints. The digital fingerprints are generated from information extracted from the video object including encoded video. The digital fingerprints can be calculated in a manner that permits identification of both the video object and operational characteristics of the video object based on matching calculated digital fingerprints with known fingerprints of known video objects. Systems and methods are described that allow a DVD to be uniquely identified and identify whether the DVD is original, copied or pirated. Systems and methods are described for computing digital fingerprints from strings of bits in which certain additional data is optionally embedded. Systems and methods are described that permit media players to access known signatures of known video objects maintained on one or more databases and to identify video objects presented for playing on the media player.

  • Patent number: 9414128
    Abstract: A method and system of providing content-aware persistent advertisements comprises the steps of ingesting and collecting VDNA (Video DNA) fingerprints of media contents playing on various network-enabled terminals including Internet browsers, mobile devices, tablets, smart televisions and so on; sending the ingested fingerprints along with other information such as metadata, user's location, etc, to the content identification server via Internet or mobile networks, and selecting accurate advertisements according to the media content and relevant information, then finally pushing the advertisements back to user's terminal. With VDNA fingerprint identification, media contents are identified by content instead of metadata or other surrounding information, so that the result of identification can be considered genuine, and the chosen advertisements based on the media content can be persistent across multiple terminals playing the same media content.

  • Patent number: 9380561
    Abstract: A method and a system for implementing CS domain paging are disclosed, applied in scenarios of performing CS domain paging for a called UE after ISR function is introduced in PS domain, and comprising: MSC/VLR only storing one Gs association; during CS domain paging, MSC/VLR sending a CS domain paging request message to the PS domain network element recorded in the Gs association in the MSC/VLR; after receiving the message, the PS domain network element initiating one or two CS domain paging procedures in the PS domain to transmit the CS domain paging to the called UE; or sending a paging response to the MSC/VLR directly without initiating CS domain paging. A method for transferring service information is also disclosed, applied in the scenarios that ISR function is activated in PS domain, and comprising: transmitting service message(s) between the ISR-associated PS domain network elements serving the UE to implement transfer of service information.

  • Patent number: 9271384
    Abstract: The present invention provides a plasma processing apparatus. The apparatus includes a vacuum chamber, a plasma reactor arranged in the vacuum chamber for plasma processing, an RF power source for providing RF signals to the plasma reactor and an RF power transmission unit for transmitting RF signals from the RF power source to the plasma reactor inside the vacuum chamber. The RF power transmission unit includes a transmission line for transmitting RF signals and an outer conductor for shielding the electromagnetic field around the transmission line. The invention can effectively avoid the problem of electric discharge when RF signals transmit in a vacuum chamber, resulting in more security and less transmission power loss.
