摘要： A collaboration 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. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. 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.

摘要： An environment for integrating a collection of video and audio processors into a multifunction system ideally suited for a common board in a hosted system. Codec and transcoding functions may be autonomous, operate under external control, be managed by a common chaperoning processor, or operated in combinations of each of these ways. The plurality of reconfigurable media signal processors can cooperatively support a variety of concurrent independent or coordinated tasks so as to provide on-demand network functions such as flexibly reconfigurable A/V transcoding, broadcast, video storage support, video mosaicing, etc., each supporting a variety of analog and digital signal formats. The system can be used for networked video services such as conferencing MCU functions, streaming transcoding record and playback video storage, call recording, conference recording, video answering (greeting playback, message record), and other functions. The architecture permits graceful growth, supporting a larger number of co-executing tasks as software algorithms become more efficient and future reconfigurable processors become more powerful, thus providing important architectural continuity.

摘要： 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.
