  • Patent number: 7130621
    Abstract: An architecture for a multimedia peer-to-peer home network allows the automated definition of peer groups, or zones, by using group labels, where each peer is capable of automatically identifying whether other peers are members of the same group, or of another group, and where each peer may freely cooperate with other peers of the same group, e.g. exchange information or share resources like storage capacity. Using this architecture, it is e.g. possible that a user who is accessing a node within a peer group has also access to any other node of the peer group, without being requested for authentication. Another characteristic is that other peer groups can be defined which have access rights to network resources and services. Advantageously, the invention simplifies network creation and operation by not requiring the user to have special networking knowledge.

  • Patent number: 7127428
    Abstract: An operator of a network (20) dynamically establishes a business relationship with a Billing Agent (26) to enable the network operator to receive reimbursement for access charges incurred by one or more users (121, 122 and 123). To establish such a relationship, the network operator first opens a communications channel to the Billing Agent after which the network operator and Billing Agent verify each other. Following verification, the network operator communicates proposed business terms and conditions, including access charges, to the Billing Agent. In response, the Billing Agent sends to the network operator an acceptance of business terms acceptable to the Billing Agent. After reaching agreement on the terms and conditions, the Billing Agent and network operator will each digitally acknowledge a formal agreement that embodies the agreed upon terms.

  • Patent number: 7095630
    Abstract: A power supply includes a supply inductor and a first capacitor coupled to form a resonant circuit to generate a resonant waveform in a resonant operation, during a first portion of an operation cycle of the power supply. A charge storage element develops an output voltage to energize a load. A rectifier is coupled to the charge storage element and to the resonant circuit and is responsive to the resonant waveform for applying the output voltage back to the resonant circuit to interrupt the resonant operation, at an end time of the operation cycle first portion, when the resonant waveform produces a first change of state in the rectifier. A first sensor senses when the first change of state in the rectifier occurs. A source of a supply current is coupled to the rectifier and rectified in the rectifier to produce a rectified current that is coupled to the charge storage element to replenish a charge therein, during a second portion of the operation cycle.

  • Patent number: 7076432
    Abstract: An apparatus and a method for processing encoded digital audio data, wherein the digital audio data is encoded using one of a plurality of encoding formats. The present invention prevents encoded digital audio data that has been copied onto a particular type of data storage medium having a unique identifier, such as a compactflash memory card, from another one of the particular type of data storage medium from being playable in an audio playback device according to the present invention. In accordance with the present invention, an encoded audio data file is encrypted using a unique identifier associated with the data storage device and a second key, an associated decoder file is encrypted using a first key, and the encrypted data and decoder files are stored onto the data storage device. During playback, a digital signal processor decrypt the audio data file in response to the second key and decrypts the decoder file in response to the first key.

  • Patent number: 7073116
    Abstract: The power of the respective codes used by the first and second error detection/correction circuitry are such that the coded bit error rate of the first data stream is more closely matched to the coded bit error rate of the second data stream. A hierarchical QAM system allows the transmission of different sources by embedding the relative constellation points. The hierarchical QAM transmitter encodes the first data stream using a code having a first detection/correction power and encodes the second data stream using a code having a second detection/correction power.

  • Patent number: 7071909
    Abstract: A method for reducing sparkle artifacts in a liquid crystal imager, comprises the steps of: low pass filtering only a first lower brightness level signal component of a video signal; and, slew rate limiting only a second lower brightness level signal component of the video signal having the low pass filtered signal component, the video signal having the low pass filtered and the slew rate limited signal components being less likely to result in sparkle artifacts in the imager. Brightness thresholds for defining the lower brightness level signal components and slew rate limits can be selected in accordance with transitions between lower and higher level gain portions of a gamma table associated with the imager, for example an LCOS imager.

  • Patent number: 7047313
    Abstract: A system enables a bi-directional communication device such as a modem to facilitate local communication between the modem and an attached PC as well as to enable the PC to conduct concurrent Internet and local communication. A bi-directional communication system employs a method for seamlessly communicating packetized data between different networks using hierarchical layers of communication protocols (e.g. including Internet Protocol (IP) and Media Access Control (MAC) layers). The method involves comparing a received IP packet destination address in a first protocol layer with a predetermined IP address to determine if there is an address match. Upon such an address match, a payload of the received IP packet is redirected from an Internet network to a local network (e.g. an Ethernet, HPNA or USB network) by substituting a second protocol layer address for a received second protocol layer address (e.g. a MAC address). In another feature, a second Application (e.g.
