远程视频传输和实时采集系统设计

设计一种基于PCI(外设部件互连)总线的远程光纤视频传输和实时采集系统,视频传输采用光纤作为传输介质,模拟视频信号经光发射机转换为光信号后在光纤中传输,最后送给视频采集卡,在计算机中进行实时显示、处理和存储。分析了光纤传输的基带直接强度调制和脉冲频率调制,介绍了视频采集卡的硬件设计及其相应的Windows98下的DMA驱动程序的设计。

Abstract]The remote video transmission and real-time capture system based on PCI bus has been established.The analog video signal is converted into optical signal and then transmitted through optical fiber to the video capture card for display storage and processing in the computer.Direct base-band intensity modulation and pulse frequency modulation are analyzed in the video transmission system.The hardware design of the PCI based video capture card and the corresponding software design of Windows 98DMA device driver are described also.
