多媒体技术介绍

多媒体技术介绍
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。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。
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）。另外，这些数据可以通过意味着信息分工和合作的计算机网络和无线电网络的方式传播。多媒体技术为现在已经占有十分重要地位的光谱应用提供了可能性。另外一方面，我们在脑子里必须时刻记得全球化，使得社会化和合法化应用。
其中的最重要一条的和流传久远的关于多媒体技术的观点是在美国波士顿的麻省理工学院多媒体研究室提出的。多媒体技术研究一直在许多不同的应用方面进行着，许多研究中心，大学和计算机科研公司正在努力致力于多媒体方面。(优秀毕业设计:www.2bysj.cn)

Introduction
Multimedia 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 .  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.
  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 ). Furthermore, these data can be transmitted though computer and telecommunication networks, which implies applications in the areas of information distribution and cooperative work. Multimedia provides the possibility for a spectrum of new applications, many of which are in place today. On the other hand , one also has to keep in mind the problems of global communication, with its social and legal implications. However, these issues will not be discussed in this book.
