摘　　要：提出了一种基于FAT32的音视频存储系统的设计方案。该设计通过初始化时进行文件列表的预分配,保证存储介质的挂载;通过使用列表文件和索引文件,保证数据的快速的精确定位和已存储数据的有效性;通过对数据的封装写入,保证数据在PC端上可以正常播放。该设计为解决嵌入式设备对音视频数据存储的特殊需求提供了一种思考方向。This paper proposes a design of audio and video storage system based on FAT32.The design is pre-assigned by the initialization file list,ensure mounted storage medium;by using the list of files and index files,ensure the effectiveness of fast and accurate positioning data that already stored;by writing the data package to ensure that the data can play on the PC side normally.This is designed to solve embedded devices provide a way of thinking about the direction of the special needs of audio and video data storage.
