【摘要】 随着人们生活水平的迅速提高,数字高清电视系统已经成为生活、娱乐中不可缺少的工具,呈现了巨大的市场需求。但是如何让数字电视量产化、人性化呢?这已经成为数字高清电视开发商、运行商等相关单位急待解决的难题,同时也由于2008年奥运会在我国的举办更是我国数字高清电视大量发展、成熟与推广的好时机,这也就对数字高清电视开发者提出了更高的要求,传统的直接面向消费者的开发方式及运营方式已经成为数字高清电视系统推广的瓶颈。结合数字高清电视系统的整个开发过程,本文介绍了数字高清电视外围设备驱动的开发,并针对目前数字电视机卡绑定机制给数字电视开发商、运营商、生产商、消费者等带来的诸多不便,本文实现了机卡分离机制的UTI驱动开发,可以大大提高数字电视的推广。本文一共分八个部分介绍了数字高清电视系统以及外围设备驱动开发。第一章主要介绍了数字高清电视的相关知识,如数字电视类型,传输信道等。第二章主要介绍了Linux设备驱动的一般概念,以及驱动开发流程。第三章主要介绍了Linux驱动的基本结构,如设备驱动和模块,驱动的加载和卸载,以及驱动的使用方法等。第四章主要是数字高清电视系统介绍以及关键芯片EM8620L。第五章介绍了外围设备前面板的开发过程。第六章介绍了外围设备遥控器的开发过程。第七章是关于外围设备UTI卡的驱动开发,这是本文的重点,针对的是机卡分离机制。另外这一章中还介绍了条件接收的知识。第八章介绍了驱动开发中的注意事项,这是本文的难点。也是一些关于驱动开发过程的总结。更多还原

【Abstract】 Accompany with the growth of standard of living, HDTV system becomes indispensable instrument in life and entertainment, showing tremendous market demand. And it is urgently puzzled to HDTV developer and operator that large-scale production and humanization of DTV. Meanwhile it is a good chance to promote and develop HDTV in our country because of 2008 Beijing Olympic Games, which sets higher requirements of HDTV developer. And traditional ways of development and operation directly to consumer have become to the bottleneck of generalization of HDTV system.Combining with the whole process of HDTV system development, this paper introduces the development of peripheral device driver in HDTV system. Against the inconvenience of set-card combination, this paper realized the development of driver for set-card separation UTI, which can promote the generalization of DTV enormously.This paper introduces the development of peripheral device driver in HDTV system through eight parts.Chapter 1, Interrelated knowledge of DTV, such as types of DTV, transmission channel etc;Chapter 2, General concepts of Linux device driver and process of the development of driver;Chapter 3, Basic structure of Linux driver, such as device driver and model, installation and uninstall of driver, use of driver etc.Chapter 4, Introduction of HDTV system and the key chip EM8620LChapter 5, The development process of front panelChapter 6, The development process of remote controllerChapter 7, The development of UTI Card driver, which is emphases in this paper focused on set-card separation, knowledge of CAChapter 8, Notice of the development of driver, which is difficulty and conclusion of development process in this paper更多还原
