摘要/Abstract

摘要： 为了解决目前各种屏幕共享技术存在的诸如计算机资源使用率过高、捕获不全面等问题，设计了应用于Windows系统的基于Hook技术和轮询检测机制的屏幕共享方案，该方案利用Hook检测速度快、占用资源少和轮询机制检测全面的特点，可以在资源使用率较低的情况下，提高屏幕共享的全面性。实际测试表明，该方法占用的计算机资源较少，并且能够较全面地反映屏幕的变化。

Abstract: A screen-sharing solution for Windows OS which combines Hook technology and polling mechanism is introduced.Due to the Hook detection is rapid and less resource-occupation，while the polling detection is comprehensive，the solution solves the problems in former screen-sharing technologies such as high resource-occupation and not comprehensive.Actual test shows that the solution can comprehensively detect the screen changes with less resource occupied，and has a good performance.

Key words: screen-sharing, hot capture, Hook, polling detection
