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: 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.

Abstract translation: 将视频和音频处理器集合到一个多功能系统中的环境，非常适合托管系统中的普通电路板。 编解码器和代码转换功能可以是自主的，在外部控制下操作，由公共伴侣处理器管理，或以这些方式中的每一种的组合操作。 多个可重新配置的媒体信号处理器可以协同地支持各种并发的独立或协调的任务，以便提供每个支持的按需网络功能，例如灵活可重构的A / V代码转换，广播，视频存储支持，视频拼接等 各种模拟和数字信号格式。 该系统可用于会议MCU功能，流转码记录和播放视频存储，呼叫记录，会议录制，视频应答（问候回放，消息记录）等功能的网络视频服务。 该架构允许优雅的增长，支持更多的协同执行任务，因为软件算法变得更加高效，而且未来的可重配置处理器变得更加强大，从而提供重要的架构连续性。

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.
