IntroductionMultimedia means, from the user’s perspective, that computer information can be represented through audio and/or video, in addition to text, image, graphics and animation . 从用户的观点，多媒体技术意味着，计算机信息不仅可以通过文本、图象、图形和动画，还可以通过音频或者视频表现出来。 For example, using audio and video, a variety of dynamic situations in different areas, such as sport or ornithology lexicon, can often be presented better than just using text and image alone.例如，利用音频或者视频，许多不同领域的动态情形，例如运动场面、鸟类生活，能够比仅仅使用文本和图象更生动形象的表现出来。 The integration of these media into the computer provides additional possibilities for the use of computational power currently available (e.g., for interactive presentation of huge amounts of information ). 多媒体与计算机的综合为计算机的普遍应用提供了额外的可行性(例如：大量信息的交互式表现)。Furthermore, these data can be transmitted though computer and telecommunication networks, which implies applications in the areas of information distribution and cooperative work. 另外，这些数据可以通过意味着信息分工和合作工作。Multimedia provides the possibility for a spectrum of new applications, many of which are in place today.多媒体技术为一连串的新应用程序提供了可能性(多媒体技术是一连串的新应用程序成为可能)，并且许多已经开发到位。8.1.1  Main Properties of a Multimedia System     If we derive a multimedia system from the meaning of the words in the American Heritage Dictionary, then a multimedia system is any system which supports more than a single kind of media. 如果我们从美国传统字典中查找a multimedia system 的字面意思，我们可以得知—一个多媒体系统是任何支持多于一种单一媒体的系统This characterization is insufficient because it onl-省略部分-through a continuous (time-dependent) and a discrete (time independent) medium.这些信息必须至少通过一种连续的(与时间有关)和一种离散的(与时间无关)媒体进行编码。     Multimedia is very often used as an attribute of many systems, components, products, ideas, etc. , without satisfying the above presented characteristics. 多媒体常常作为许多系统、组件、产品、理念等的一个特性，但却并不满足以上所陈述的多媒体特性。From this view-point our definition is deliberately restrictive.在这一观点上，我们的定义是故意限制的(过于苛刻的)。     Thus, two notions of multimedia can be distinguished:所以，必须将两种含义的多媒体区分开来：      ~ "Multimedia", strictly speaking:严格意义上的多媒体：         In this context, continuous media will always be included in a multimedia system. 在这一范围中，多媒体系统必然包括连续媒体。At the same time important timely marginal conditions (through the continuous media) for the processing of discrete media will be introduced. 同时为了处理离散媒体，它也引入了重要的时间边界条件(通过连续媒体)。They have barely been considered in computer use until now.但他们直到现在才在计算机中得到使用。      ~ "Multimedia", in the broader sense:广义的“多媒体”Often the notion multimedia is used to describe the processing of individual images and text, although no continuous medium is present. 在处理单个的图像和文本时，尽管不是连续型的媒体，但我们往往还是使用多媒体这个概念。Many of the processing tasks in this environment will also be necessary in the multimedia system according to the restrictive definition. 同时这个层面上的许多处理事务在上述的狭义多媒体系统中也是必不可少的。In any case, if more media are processed together, one can talk about multimedia according to this second notion.所以，在这个意义上只要同时处理了多种媒体，就可以使用媒体这个提法。 关 键 词： 专业英语 译文 8.1 教程 计算机
