摘要： The invention provides a method and apparatus for management of communications over media of finite bandwidth. One embodiment of the invention allows management of communications comprising a plurality of data streams from a plurality of sources. One embodiment of the invention effectively quantifies and controls data streams comprising data transferred at either regular or irregular data rates. One embodiment of the invention provides for estimation of data rate needs, measurement and analysis of current and historical data rate parameters, dynamic allocation of available bandwidth, and supports cooperation between data sources and destinations in the management processes.

摘要： 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.

摘要： 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.

摘要： Disclosed are communication apparatus, a SATA communication device, a system, an enhanced port multiplier and a method for, among other things, establishing a covert communication channel in a protocol-compliant link. In one embodiment, a communication apparatus includes a link interface and a supplemental message interface. The link interface is configured to communicatively couple the communication apparatus to the link for accessing a data stream passing through the link in accordance with a standardized protocol. The supplemental message interface is configured to exchange a supplemental message within the data stream to establish a covert communication channel in the link. The supplemental message supplements the standardized protocol without violating the protocol.
