一、分布式多媒体系统结构 多媒体系统除了能够像计算机一样处理离散媒体如文本、图像外,它的一个基本特性就是能够综合地处理带有时间关系的连续媒体,如音频、视频和动画。这就意味着多媒体系统在处理信息时有着严格的时序要求和很高的速度要求。当系统应用扩大到网络范围之后,这个问题将会更加突出,就会对系统结构、媒体同步、多媒体操作系统及应用服务 First, the distributed multimedia system architecture In addition to being able to handle discrete media such as text and images like computers, one of the basic features of multimedia systems is the ability to process serially connected media such as audio, video and animation with time. This means that multimedia systems have strict timing requirements and high speed requirements for processing information. This problem will be more prominent when the system application is expanded to the network range, and will have a great impact on the system structure, media synchronization, multimedia operating system and application service
