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.

Network repository for metadata

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.

Multi-view display system

In some embodiments, an apparatus includes interface circuitry to receive signals including video signals and drawing commands, and a command interpreter to receive the drawing commands and provide on screen display (OSD) signals in response to the drawing commands. Video processing circuitry processes the received video signals to provide processed video signals, and a blender to blend the OSD signals and the processed video signals to produce blended video signals including the OSD signals and the processed video signals. Other embodiments are described and claimed.

On screen displays associated with remote video source devices

A method and system for providing advanced storage features using commodity, consumer-level storage devices is provided. The advanced storage system is a component that is connected between the computer system and one or more physical disk drives. The host interface of the advanced storage system presents itself to the computer system as a virtual disk drive that implements the commands of consumer-level storage hardware that are familiar to the host controller of the computer system. Similarly, the storage device interface of the advanced storage system presents itself to one or more disk drives as a consumer-level host controller, regardless of the actual topology of the physical storage devices that are connected. This system provides a simple way for a user to combine low-cost, consumer-level hardware to add advanced storage features to a computer system.

Smart scalable storage switch architecture

In some embodiments, an apparatus includes device functional circuitry to perform at least one service; and network interface control circuitry to control interaction between the apparatus and a network. The network interface control circuitry includes a service discovery module to (1) send a presence announcement message to be transmitted outside the device to let other devices outside the device know of services the device may perform and (2) to receive presence announcement messages from the other devices outside the device to learn what services to the other devices may perform. In some embodiments, the network interface control circuitry includes a dynamic connection management module. Other embodiments are described and claimed.

Automated service discovery and dynamic connection management

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.

Ensuring physical locality of entities sharing data

A method and apparatus for data stream control for network devices. Some embodiments of an apparatus include a receiver to receive a token for a command associated with a stream of data, where the command is one of multiple command types. The token has a fixed size and format, and the token is provided in a field of a data packet. The apparatus further includes a network unit to determine the type of command based on the token, to parse a set of fields in the data packet for command data, and implement the command.

Data stream control for network devices

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.

Synchronizing related data streams in interconnection networks

A method and apparatus for bandwidth reservation for data flows in interconnection networks. Some embodiments of an apparatus for transmitting a data stream include a transmitter to transmit a data stream to a recipient apparatus, the data stream including a plurality of data packets. The apparatus further includes a receiver to receive a response from the recipient apparatus regarding data packet arrival status, and a network unit to direct the operation of the transmitter, the network unit to direct the transmitter to maintain the data stream with a constant bandwidth.

Bandwidth reservation for data flows in interconnection networks

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. Typically, the PDN is implemented so that no secret in Ingress or Egress circuitry (for use or transfer by the Ingress or Egress circuitry) is accessible in unencrypted form to software or firmware within the PDN or to any entity external to the PDN. Other aspects of the invention are methods for protecting content in a PDN (e.g., an open computing system) and devices (e.g., multimedia graphics cards, set top boxes, or video processors) for use in a PDN.
