摘要

一项利用电脑科技支持科学家和专业人士合作的调查正在进行。本研究的一个组成部分是在高性能工作站网络上构建分布式、实时、数字视频会议系统。讨论了构建该系统的动机，并概述了数字音视频流实时通信的操作系统和网络支持机制的设计。作者介绍了一种新的进程间通信范式，称为实时生产者/消费者(RTP/C)范式。RTP/C范式为表达与处理器时间相关的计算和对程序的实时行为进行推理提供了一个框架。

System design for workstation-based conferencing with digital audio and video

An investigation is conducted of the use of computer technology to support collaboration among scientists and professionals. One component of this research is the construction of a distributed, real-time, digital video conferencing system on a network of high-performance workstations. A discussion is presented of the motivation for the construction of the system, and the design of operating system and network support mechanisms for real-time communication of digital audio and video streams is outlined. The authors introduce a novel paradigm of inter-process communication called the real-time producer/consumer (RTP/C) paradigm. The RTP/C paradigm provides a framework both for expressing processor-time-dependent computations and for reasoning about the real-time behavior of programs.<>
