Abstract: A teleconferencing system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. The system provides an audio/video (AV) path (13) for carrying AV signal among the workstations, a video mosaic generator (36) for combining images, and an audio summer or mixer (38). At least part of the AV path (13b) is implemented with unshielded twisted pair wiring. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of data at intermediate hops, as well as video mosaicing and cut-and-paste technology.

Abstract: This invention relates to a multimedia device (100) for use in multimedia collaboration apparatus and systems. Such apparatus and systems typically contain processing units (118) audio reception and transmission capabilities (140, 142), as well as video reception and transmission capabilities (146, 142). The reception and transmission capabilities allow analog audio/video signal transfer over UTP wires for audio transmit/receive. The reception, transmission, and decoding capabilities could exist in a single packaging. This or another single packaging can support a plurality of multimedia network signal formats, including analog plus digital or all digital.

Abstract: Methods and systems are disclosed for providing multimedia telecommunication services to multimedia workstations (100, 102). The multimedia workstations (100, 102) communicate with a multimedia central office (112) which includes a digital switch complex (150) coupled to a public digital telephone network (106), and at least one twisted pair transceiver (157) coupled to at least one twisted pair link in a telephone loop plant. The multimedia central office (112) further includes at least one switch complex (154) operatively associated with the digital switch complex and at least one twisted pair transceiver. The multimedia central office is capable of transceiving signals with multimedia workstations interfaced to the public digital telephone network, and with multimedia workstations interfaced to at least one twisted pair link in the telephone loop plant. The signals which are transceived include audio signals, video signals, and digital data signals used in providing the multimedia telecommunications services.
