多媒体终端是一种能综合各种不同媒体(语音、文字、数据、图象和活动影像等),集电话机、电报机、传真机、电视机和计算机等为一体的新型通信终端。 媒体在电子计算机领域有两种含义,一是指用以存储信息的实体,如磁带、磁盘、光盘、半导体存储器等等;二是指承载信息的载体,如文字、声音、图象等。多媒体技术中所指的媒体是指后者。信息是人类在思维活动中形成的意念和知识,如果没有承载它的媒体是无法表现出来的,也就无法传递、交换、保存、加工和利用,这种媒体我们称之为信息媒体。载于多种信息媒体的信息最终由人类的听觉、触觉、视觉器官来感知。
A multimedia terminal is a new type of communication terminal that integrates various media (voice, text, data, images and moving images, etc.), a set telephone, a telegraph, a facsimile, a television and a computer. Media has two meanings in the field of electronic computers. One is the entities that store information such as tapes, disks, optical disks, semiconductor memories, and so on. The second is the carrier that carries information, such as words, sounds, images, and so on. The media referred to in multimedia technology refers to the latter. Information is the idea and knowledge that human beings form in their thinking activities. If the media without it can not be displayed, the information can not be transmitted, exchanged, preserved, processed and utilized. We call it the information media. Information contained in a variety of information media is ultimately perceived by human hearing, touch, and visual organs.
