  • Patent number: 9934227
    Abstract: A method and apparatus for a network repository for metadata. Embodiments of a data repository include a memory to store data including one or more data content items, where each data content item is associated with zero or more metadata items, and where each data content item is associated with a handle and each metadata item is associated with an attribute name. The data repository further includes a network interface configured to communicate with a client device, and a control unit configured to control the storage of data in the memory, where the control unit provides functions for writing data to and reading data from the memory and where the control unit is to transfer the data without interpretation.

  • Patent number: 9693046
    Abstract: Embodiments of the invention are generally directed to a multi-view display system. An embodiment of an apparatus includes a display screen to display multiple views simultaneously, and a controller to control the views presented on the display screen. The apparatus is configurable by the controller to provide multiple view settings, the view settings including a first setting in which the apparatus provides a single view to each viewer of the display screen and a second setting in which the apparatus provides a first view to a first viewer of the display screen and a second view to a second viewer of the display screen. A first filtering element filters views presented to viewers of the display screen such that an intended view is displayed to one or more viewers.

  • Patent number: 8233432
    Abstract: A method and system for ensuring that data is only distributed within a certain physical area are disclosed. In one embodiment, a method provides that data is distributed only if the distance between a source and a sink is within a distance threshold. Under this system, the distance between the source and the sink may be estimated directly or indirectly. In some embodiments, the distance may be estimated by estimating the propagation delay for a signal traversing between the devices. The physical distance between the devices may be determined from the propagation delay. If the physical distance is outside a threshold value, the source may be prohibited from transmitting the data or the sink may refuse to display the data.

  • Patent number: 7936790
    Abstract: A method and apparatus for synchronizing related data streams in interconnection networks. Some embodiments of an apparatus include a transmitter to transmit a data stream to a second apparatus, where the transmitter transmits a data packet to the second apparatus. The apparatus further includes a clock, with the apparatus providing a first timestamp for the data packet using the clock upon transmission of the data packet. The apparatus includes a receiver to receive responses from the second apparatus, with the apparatus providing a second timestamp upon receiving a returned packet from the second apparatus, with the returned packet containing timestamps for the receipt and transmission of the packet by the second apparatus. The apparatus includes a network unit to direct the operation of the apparatus, the network unit to determine a start time for decoding of the data stream by the second apparatus based at least in part on the timestamps for the packet.

  • Patent number: 7702925
    Abstract: In some embodiments, the invention is a personal digital network (“PDN”) including hardware (sometimes referred to as Ingress circuitry) configured to transcrypt encrypted content that enters the PDN. Typically, the transcryption (decryption followed by re-encryption) is performed in hardware within the Ingress circuitry and the re-encryption occurs before the decrypted content is accessible by hardware or software external to the Ingress circuitry. Typically, transcrypted content that leaves the Ingress circuitry remains in re-encrypted form within the PDN whenever it is transferred between integrated circuits or is otherwise easily accessible by software, until it is decrypted within hardware (sometimes referred to as Egress circuitry) for display or playback or output from the PDN.

  • Patent number: 7502470
    Abstract: In a class of embodiments, the invention is an open computing system (e.g., a PC) in which a protected, closed subsystem is embedded. The closed subsystem typically includes multiple parts that ensure that content protection keys and protected content are never revealed outside the closed subsystem. Content (e.g., high-definition digital video) that enters the closed subsystem (and is typically decrypted and re-encrypted within the closed subsystem) is afforded a similar level of protection within the open system as can be obtained in standalone closed systems. Other aspects of the invention are methods for protecting content within an open computing system, a closed system (or disk drive thereof) configured to be embedded in an open computing system, and circuitry configured to be embedded in an open computing system for combining the output of a closed subsystem with other output (e.g., graphics and/or audio output) of the open computing system.
