【摘要】 介绍了一种机顶盒上使用的BIOS的分析、设计和实现。该BIOS解决了目前机顶盒产品在软件升级功能上存在的不足,不仅能够完成BIOS的基本功能(在开机后加载机顶盒的应用程序,进行系统参数配置),还能够访问网络文件服务器、进行应用程序的升级,实现了SBA(Software definedBroadbandAc cess)的设计思想,即在相同的硬件平台上,通过下载不同的应用软件,实现不同的功能。更多还原

【Abstract】 This paper presents the analysis, design and implementation of a BIOS for a kind of STB(Set Top Box).This BIOS improves the function of software upgrading.It can not only accomplish functions such as loading the application program and configuring system parameters, but access the network file server and download files as well,fulfilling the idea of SBA(Softwaredefined Broadband Access),that is,achieving different functions by downloading corresponding application softwares on one hardware platform. 更多还原
