摘要
分析了电子教材的发展现状,探讨了制约发展的瓶颈问题:数字版权保护、可阅读性和多格式支持。据此瓶颈,对当前阅读器的数字版权保护技术做了综述,介绍了电子纸的基本原理、特性,在综合液晶屏和电子纸的优点的基础上,设计并实现了一种可实现面向数字版权保护的EPD电子教材,详细阐述了EPD电子教材的结构和实现流程,包括:面向数字版权保护、操作系统移植与实现、多获取方式和多格式支持、GUI实现、EPD的显示控制和电源管理。
This paper analyzed the current development of electronic teaching materials, and probed into the restricting elements of the development, digital copyright protection, readability and multiformat support. Also, it reviewed the current readers＇digital rights protection technology, and intro- duced the basic principles and properties of e-paper, and synthesized the advantages of the LCD screen and e-paper, designed and implemented the EPD electronic materials, which is an available way for digital copyright protection, described in detail the structure and implementation process of EPD electronic materials,including：protections facing the digital copyright, the migration and implementation of the operating system,multi-access mode and multi-format support, GUI implementation, EPD display control and power management.
