近年来计算机对图形、图像及声音等媒体的信息处理能力有了迅速的发展。图、像和声不仅在科学计算分析、工程设计领域获得广泛应用,而且在更广的应角范围如:信息查询、教育、培训、广告及企业管理中已成为重要的信息媒体。因此,不难想像,常用的计算机应不只限于对数据的处理,而是应扩大其功能,对其他信息媒体也能方便地处理。简言之,人们要求一般计算机将对多媒体的信息进行处理。现在这个转变正在到来。不久的台式计算机将实现这些功能。很多人在思想上还没有这样的准备。但转变肯定会到来,国外的一个知名信息咨询机构预计至1994年计算机的多媒体市场将达103亿美元,其中事务用途占44亿,信息查询占34亿,教育和培训占25亿。计算机的多媒
In recent years, computers have rapidly developed information processing capabilities for media such as graphics, images and sound. Graphs, harmony and so on are not only widely used in scientific calculation and analysis and engineering design, but also become important information media in a wide range of fields such as information inquiry, education, training, advertisement and business management. Therefore, it is not hard to imagine that commonly used computers should not only be limited to the processing of data, but should expand their functions and be easily handled by other information media. In short, people are asking the average computer to process multimedia information. Now this shift is coming. Soon the desktop computer will achieve these functions. Many people are still not mentally prepared for this. However, the change will surely come. A well-known foreign information consulting agency predicts that the multimedia market of computers will reach 10.3 billion U.S. dollars by 1994, of which 44.4 billion are for business use, 3.4 billion for information inquiry and 2.5 billion for education and training.
