IEEE1394总线在视频输出、截取板卡中的应用

IEEE1394高速串行总线支持400Mbps的等时和异步传输应用已经到了实用化阶段，具有可热插拔，使用方便灵活等特性，使其成为未来高速总线的首选。本文利用1394总线对高速视频数据传输的特性，实现了1394总线在高速视频输出、截取中的应用。

The high-speed serial bus-IEEE 1394-perhaps will be the first choice for people engaged in the field of image processing， data transmission for its high performance. IEEE 1394 has become the factual standard. The paper makes use of the characters of IEEE 1394 for high-speed data transmission realized the application of IEEE 1394 bus in video outputting and getting board.
