摘　　要：为了有效地解决图形终端应用协议中如多媒体播放等计算密集型图形操作影响终端服务质量的问题,文中分析了终端应用协议中的多媒体播放过程,通过服务器和终端之间对多媒体处理能力的协商。In order to resolve issues induced by graphical operations of computation-intensive applications such as multimedia play in graphical terminals, we analyze the procedure of multimedia play using terminal application protocols, and propose an adaptively distributed mechanism to implement computationally intensive graphical operations by negotiating capabilities between servers and terminals, where we implemented the control and decoding procedures of multimedia play on the server and the terminal respectively. The test results show that the mechanism could dramatically reduce the server load and greatly improve the quality of multimedia play.
