JPEG2000高清采集系统软件设计与实现

Design and Implementation of HD Capturing System Based on JPEG2000

介绍一套Windows平台下基于JPEG2000采集卡的高清采集系统,设计并实现了采集卡的驱动程序与应用程序。驱动程序、应用程序以及驱动程序与应用程序的同步分别采用DMA传输机制、多线程和Event方式。实验表明该系统,能实现高清数据的采集、实时编码与存储,对高清节目制作具有重要意义。

This paper introduces a HD capturing system based on JPEG2000 capturing card in Windows,and the cards driver and application programme are designed and implemented.The Driver is designed in DMA mode,the application programme is designed in Multi-thread,and they are synchronized with event.Experiments show that the system runs well with designed software and the system can capture,code and store HD data at the real time.It is very important for compiling HD programmes.
