摘要
介绍了视频存储所采用的基本方法,分析了FAT32文件系统的基本原理。针对HDTV视频码流数据量大、传输速率高的特点,在硬件上采用了AVR单片机和FPGA相结合的方法,实现了在没有操作系统的情况下对视频码流的硬盘存储,并给出了相关的软件实现。
This paper discusses the basic method of video storage, and analyses the basic principle of FAT32 file system. For the high transmission speed and mass data of HDTV video stream, a method based on FPGA and AVR microcontroller is proposed, which can store the video stream in a hard disk without an operation system. A software realization based on the hardware platform is provided.
