A key-sharing scheme is used to control distribution and use of video and audio content in personal digital assistants (PDAs) and other wireless devices. A private key is split into key-shares using a Blakley-Shamir key splitting technique and the key-shares are distributed to various network entities including a finance server and security server. Key-shares are also stored in a user's subscriber identity module (SIM) and a security processor of the PDA. The key-shares from the network entities are provided to the PDA after the user requests specific video or audio content and credit verification is performed. The PDA's security processor combines the key-shares to form the decryption key for use in playing the content by the PDA's communications processor. When a service limit is reached, the PDA's security processor purges the key-shares to prevent further use of the content.

A system for two processors communicating though unidirectional links by embedding a strobe signal into the data by providing differential signals with different common mode signal levels.

Strobe through differential signaling

A personal information system comprises a personal kiosk system ( ) and a personal presence identifier ( ) carried by a user and coupled to the personal kiosk system by a short-range two-way wireless link. The personal kiosk system and the personal presence identifier are arranged and programmed to establish a two-way personal area network with one another when the personal presence identifier is within wireless transmission range of the personal kiosk system. The personal presence identifier and the personal kiosk system are also arranged and programmed to exchange needs specifications and capability specifications with one another after establishing the two-way personal area network.

Personal information system using proximity-based short-range wireless links

The present invention provides a method for communicating signaling messages associated with a communication system whereby a network within the communications system is responsible for setting up a signaling path between users of the communication system. However, once that signaling path is established by the network, the users may communicate with each other whereby the network is not needed to pass data between the users thereby substantially decreasing demand on the network and freeing it for other system functions.

Method for communicating signaling messages through a broadband network

A peer device ( ) is arranged and programmed for handling a transaction at a point of sale provided by a merchant, and a personal presence identifier ( ) is carried by a user and coupled to the peer device by a short-range two-way wireless link. The peer device and the personal presence identifier are arranged and programmed to establish a two-way personal area network ( ) with one another when the personal presence identifier is within wireless transmission range of the peer device. The personal presence identifier and the peer device are also arranged and programmed to exchange needs specifications ( ) and capability specifications ( ) with one another after establishing the two-way personal area network.

Transaction system and method therefor

A peer device ( ) is arranged and programmed for maintaining a virtual queue for an event, and a personal presence identifier ( ) is carried by a user and coupled to the peer device by a short-range two-way wireless link. The peer device and the personal presence identifier are arranged and programmed to establish (58) a two-way personal area network with one another when the personal presence identifier is within wireless transmission range of the peer device. The personal presence identifier and the peer device are also arranged and programmed to exchange (82) needs specifications and capability specifications with one another after establishing the two-way personal area network.

Virtual queuing system using proximity-based short-range wireless links

A wireless, peer-to-peer, capability addressable network ( ) is disclosed. The network ( ) accommodates any number of peers ( ). Network connections are formed based upon proximity between peers ( ) and upon a needs and capabilities evaluation ( ). Wireless communications occur at a sufficiently low power to form a detection zone ( ) of less than about five meters for many peers ( ).

Capability addressable network and method therefor

A system for encapsulating data into data packets to be transmitted through a broadband communications system includes a first B channel buffer ( ), a second B channel buffer ( ), a D channel buffer ( ), a controller ( ), and a packet buffer ( ). The controller ( ) receives 2B&plus;D data on an ISDN line and reformats the data through the use of the buffers so that the resulting packet ( ) includes a repeating pattern of 4 bytes of B data, 4 bytes of B data, and 1 byte of D data. Each packet preferably includes 11 sets of the repeating pattern for a total of 99 bytes of ISDN data in a packet.

Method and apparatus for encapsulating ISDN data in a broadband network

A circuit and method for personalizing an electronic device (,) through a personal area network (,). Electron devices (,) have transceivers (,) for transmitting a self-initiated message that includes an identification code of the electronic device. Transceivers (,) are also capable of receiving a self-initiated message sent from other electronic devices. The received message causes a response message to be transmitted in response to the identification code in the self-initiated message. Communication between two electron devices (,&prime; and,&Prime;) is established when the devices are determined to be compatible. The application of the electronic device is configured based on the response message and data is displayed by the electronic device based on the application.

Personal data storage and transaction device system and method

A method for bonding (,) to a device (,). The method includes a step of transmitting a beacon message (,). The method also includes steps of (i) selecting a beacon opcode (,), (ii) selecting an identifier (,), (iii) selecting an identifier type (,), (iii) selecting an identifier address (,), composing the beacon opcode (,), the identifier (,), the identifier type (,) and the identifier address (,) into the beacon message (,). The method also includes a step of receiving, in response to the transmitting step, a make bond message (,).

Method for authorizing couplings between devices in a capability addressable network

A method (,, FIG.,) controls CU (,, FIGS.,) hand-off in a non-geostationary orbit (NSGO) satellite system (,, FIG.,) without consuming large amounts of bandwidth or satellite processing power. Using method (,), a network control facility (NCF) (,, FIGS.,) divides the earth (,, FIG.,) into suitable regions,(FIG.,), or geographical areas of the earth sized so that all of the CUs (,, FIG.,) within a region (,) can be handed-off as a group rather than handling each station individually. When it is determined through the method (,) that it is time to hand-off communications in a particular region, all CUs within that region are directed to effectuate a hand-off at substantially the same time.

A system for encapsulating ATM cells into larger data packets to be transmitted through a broadband communications system includes an ATM cell receiver (410), a data packet formatter (430), a buffer (434), and a data packet formatter controller (438). The ATM cell receiver (410) receives ATM cells and sends them to the buffer (434) which is included within the data packet formatter (430). Data packet formatter controller (438) controls the insertion of ATM cells into the buffer (434), and also optionally compresses the ATM cells to increase the apparent bandwidth of the system.
