摘要： Improved image quality is realized in a parallax-free teleconferencing display by increasing the camera light budget, that is, by increasing the light available to the camera, while maintaining a common optic axis between the camera and the display screen. Light-attenuating devices, such as color filters, are repositioned out of the path of light entering the camera. In this manner, image quality is improved while color capability is maintained.

摘要： The advantages of both a color display and a high-resolution monochrome display are realized in a single display system by eliminating color filters from the display screen of the display system and illuminating the display screen with either colored light or white light to provide color or high-resolution monochrome capability, respectively. Simultaneous color and high-resolution monochrome capability is realized by illuminating predetermined portions of the display screen with only colored light while illuminating different portions of the display screen with only white light.

摘要： Direct eye-to-eye contact and compactness are achieved in a video display system including a camera positioned behind, or opposite the viewing side of, a display screen having first and second modes of operation. As a result, the camera and the person or persons viewing the display are on opposite sides of the display screen. The display screen is controlled to switch from the first or image display mode to the second or substantially transparent mode. When the display screen is in the substantially transparent mode, the camera is controlled to record images appearing on the viewing side of the screen.

摘要： A system and method for optimizing usage of a communications transmission medium. The transmission medium may be sliced into time and frequency domains so as to create time-frequency slices for assignment to users having varying access rates and user-application requirements. Through scheduling of the various speed users within the frequency and time domains, the system and method can efficiently allocate and make use of the available spectrum, thereby accommodating higher rate users requiring greater bandwidths and time slot assignments while still preserving cost-efficient access for lower speed users. Depending on the signal modulation scheme, the time-frequency slices may be allocated on non-contiguous frequency bands. The system and method is also applicable to code-division multiple access (CDMA) techniques by slicing the available code space along time-code domains, frequency-code domains or, in three dimensions, along time-frequency-code domains. Users may be efficiently scheduled based on code space requirements so as to optimize use of the communication medium.

摘要： Real-time hardware primitives are added to packet switches to provide efficient support for inward multicasting. The lookup table used for routing is extended by adding additional opcode and operand fields into the routing table and by including ALU circuitry to process these fields and corresponding fields in the arriving cells. Memory word widths can be extended with minimal additional chip count and the ALU can be a small addition in a header processing VLSI, thereby giving only a modest increase in complexity. By including real-time processing in the switch it is possible to solve the ACK implosion problem associated with high-speed reliable multicasting transport protocols. By keeping the primitives as general as possible, other applications can benefit as well from these real-time primitives.

摘要： The present invention is a signaling and control architecture for establishing a connection between mobile users in a wireless ATM LAN. The ATM LAN includes a plurality of portable base station (PBS) switching nodes coupled together to enable communication between said nodes, wherein the nodes are configurable in an arbitrary topology to form an ad-hoc network. The present invention includes network management techniques for configuration of data tables used for connection control. Mobility management techniques are disclosed to handle mobile sign-ons and idle handoffs, locate mobile users during connection and setup and perform handoffs when a mobile is actively involved in a connection. Connection control procedures are also included for setting up and releasing connections on demand.
