Abstract: 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.

Key words: HDTV, File system, FAT32
