摘要
本文提出了一种创建Linux设备驱动程序框架的方法，该框架将用于表示和控制机顶盒(STB)和电视机(iDTV)中与数字电视相关的硬件组件。在过去的几年里，LinuxTV被认为是PC电视卡的有前途的架构，但是从Linux DVB API v3的发布开始，在嵌入式系统方面没有任何进展。因此，本文试图改进和取代现有的Linux DVB范式，并引入适用于嵌入式系统并对其进行优化的概念。开发了分层的软件体系结构，简化了内核驱动程序的开发，并向用户空间应用程序导出定义良好的api。
This paper presents an approach to create Linux Device Driver Framework which will be used for representation and control of DTV related HW components found in Set-top boxes (STB) and TV sets (iDTV). During previous years LinuxTV was established as promising architecture for PC TV cards, but from the announcement of Linux DVB API v3 there was no progress toward embedded systems. Therefore, attempt is made to improve and replace existing Linux DVB paradigm, and to introduce concepts applicable and optimized for embedded systems. Layered SW architecture is developed, which simplifies Kernel Drivers development, and export well defined APIs to user space applications.
