摘要
本文介绍了一种基于PCI局部总线的压缩视频数据实时传输的实现方法。该方法考虑到硬件设备和Windows2000下应用程序的具体要求,借助VtoolsD编写设备驱动程序,在驱动程序中利用全局事件控制双缓冲方式来实现视频数据的实时传输。
In this paper, a method of the real-time transmission of the compressed video data through the PCI bus is introduced. The method considers the specific request both on the hardwares and the programs in Windows2000 system, and is programmed by VtoolsD. In driving the device, two global event controlled buffers are used to realize the real-time transmission of the compressed video data.
