本文认为UNIX在支持多媒体应用程序的作用。特别是，我们认为UNIX操作系统（一般）和UNIX I/O系统（特别是）的能力，以支持同步的一些高带宽的数据集，必须结合起来，以支持广义的多媒体系统。本文件分为三个主要部分。第一部分回顾了多媒体应用程序固有的要求和特征。第二部分回顾了UNIX和UNIX I/O模型提供的功能。第三部分对比了多媒体的需求和UNIX支持这些需求的能力，特别注意UNIX的问题方面。最后，我们勾勒出一个方法，我们正在研究解决多媒体处理问题：使用分布式操作系统提供一个单独的数据和处理管理层的多媒体信息。
This paper considers the role of UNIX in supporting multimedia applications. In particular, we consider the ability of the UNIX operating system (in general) and the UNIX I/O system (in particular) to support the synchronization of a number of high-bandwidth data sets that must be combined to support generalized multimedia systems. The paper is divided into three main sections. The first section reviews the requirements and characteristics that are inherent to multimedia applications. The second section reviews the facilities provided by UNIX and the UNIX I/O model. The third section contrasts the needs of multimedia and the abilities of UNIX to support these needs, with special attention paid to UNIX’s problem aspects. We close by sketching an approach we are studying to solve the multimedia processing problem: the use of a distributed operating system to provide a separate data and processing management layer for multimedia information.
