摘　　要：DVD光盘刻录机是一种以光盘为存储媒介的录像机 ,他记录密度高、容量大 ,可实现记录图像和音质的高保真 ,可以任意进行编程播放、快进、快退、重复和跳曲等功能。研制的新一代 DVD光盘刻录机的控制系统是一个嵌入式系统控制及图形图像处理软件和智能文件管理系统 ,他采用 ES6 12 8F内置的 RISC进行系统控制和图像处理 ,将MPEG- 2编码后的数据流转换为 IDE接口数码流 ,按 FAT32文件系统存贮到光盘上。本文介绍了 DVD光盘刻录机的软件控制系统结构和程序模块 ,并给出了软件具体实现的主要流程图和部分程序。DVD disc recorder is a kind of recorder by disc as memory medium with high consistency and capacity, fulfilling the high fidelity of the picture and timbre and with the functions of program playing, forward playing, backward playing, repeat and skip playing, etc. The control system of the new generation DVR which we developed is a kind of embedded system, graphic,image processing software and intelligent file management system. It uses the inbuilt RISC (ES6128F) to process the system control and image processing, change the encoded MPEG-II data stream into IDE interface data stream and then store them into DISC as FAT32 file system. The article introduces the software control system and program module of DVD disc recorder concretely brings forward the main flow chart & part of the program to realize the software.
