摘要
在视频采集系统中,需要根据不同的系统要求对视频采集进行控制。本文介绍了一种使用FPGA进行视频采集控制的设计与实现方案,该系统采用了灵活可配置的FPGA芯片对视频解码芯片SAA7114H进行视频采集控制,使之在不改动系统硬件电路的条件下,只要根据不同的系统需要进行不同的FPGA配置,就可以将该视频采集系统应用到各种视频信号处理系统中。
In video data acquisition system, different system must have different system controller. A video data acquisition controller system based on FPGA is presented here. Special video decoder saa7114H and flexible configurable FPGA are used in this digital video data acquisition system. Based on different use and different system configuration, this system can be used in different digital video process system without any change in hardware design.
