媒體通信係統應用子係統綜合論述(ppt 58頁)

媒體通信係統應用子係統綜合論述內容提要：
協同計算：
Collaborative computing 　
現在工作站和PC機都配有很強的音頻和視頻功能,若把它們用高速網絡聯在一起，那麼就為人們提供了一個協同計算環境，協同計算通常又稱為計算機支持的協同工作(CSCW)。
The current infrastructure of networked workstations and PCs,and the availability of audio and video at these end-points,makes it easier for people to cooperate and bridge space and time. In this way, network connectivity and end-point integration of multimedia provides users with a collaborative computing environment. Collaborative computing is generally known as Computer-Supported Cooperative Work (CSCW).
協同維數：
Collaborative Dimensions　
電子化的協同工作係統可根據時間、用戶範圍和控製這三個參數進行分類[WSM+91]。這樣協同工作係統可以被劃分一個三維空間（如圖11.1所示）。
Electronic collaboration can be categorized according to three main parameters: time, user scale and control [WSM+91]. Therefore, the collaboration space can be partitioned into a three-dimensional space (shown in figure 11.1).
