电子信息工程专业英语(李白萍)中文翻译

Videoconferencing is a typical example of multimedia, combining two media (audio and video), interaction, human users, and synchronization. By contrast, broadcast television allows no backward channel for the information receiver to interact with the information provider, and it is therefore not regarded as a multimedia communication.
The types of interaction in multimedia systems are as follows:
• Search and browse. These correspond to database access functions for extracting the required multimedia information from storage.
• Interactive “buttons”. A frame of information (i.e., a screen or portion of a screen) may contain buttons that can be selected(e.g. , using a cursor)to control the presentation of information, and to pass on to another frame. Examples of “buttons” are lists of options, menu selections, and portions of the displayed information that can be selected to obtain additional information on that subject.
