Remote Control method and server

本发明是为了使广泛地用在个人计算机中的窗口系统及个人计算机的应用能在并不具备足够的处理能力的便携式信息终端中操作。将在便携式信息终端210中生成的诸如来自操作员的键输入等输入信息发送到执行或模拟不受生成描绘图象的功能限制的任意窗口系统的远程支持服务器240。然后支持服务器将描绘图象转换成适用于便携式信息终端的图象并将其作为描绘指令送回便携式信息终端210。便携式信息终端210接收这一优化图象的描绘指令供显示之用。 A window system of the kind used in personal computers is operable in a portable information terminal which does not have a sufficient processing capability by having input information. such as a key input from an operator, generated in a portable information terminal 210 sent to a remote supporting server 240 where it executes or simulates an arbitrary window system which is free from restriction of functions to generate a rendering image. The supporting server then converts the rendering image to an image suitable to the portable information terminal and sends it back to the portable information terminal 210 as a rendering instruction. The portable information terminal 210 receives the rendering instruction of this optimised image for display.
