DVD视盘系统盘片格式处理模块的研究与实现

The Research and Realization of DVD Data Format Processing Model

DVD盘片处理模块是DVD视盘系统的关键技术之一,本文介绍了DVD数据结构,通过分析将主数据记录到DVD盘片上的过程,实现了DVD视盘系统主控程序中盘片格式处理模块。该模块是实时任务的,采用中断驱动状态转移的机制。

The module of processing DVD's disc format is one of the key techniques in DVD digital video system.In this paper,we introduce the data structure of DVD and implement the module of processing DVD's disc format by analyzing the process of how the DVD data is recorded into disc.This module is based on real Real-Time Task and adopts Interruptions Driving States Shifting mechanism.Consequently it improves the efficiency of executing programs.
