摘要
介绍了基于嵌入式实时操作系统uCOS -ii的有线数字电视机顶盒的设计及其组成 ,并阐述其具体实现 ,该机顶盒以实时多任务操作系统uCOS -ii为核心 ,以信道解码模块、信号解码模块和网络链接接口模块、遥控交互模块为基础 ,以有线电视机顶盒专用芯片MB87M2 14 0为主要实现方式 ,有效实现了数字电视信号的交互应用 ,如视频点播 (VOD)
This paper introduces the design and composition of wired digital TV set top box based on embedded real time operating system uCOS-ii, and elaborate it's realization. The core of set top box is real time multi-tasking operating system uCOS-ii. The bases are channel decode module, signal decode module and network link interface module, remote controll interaction module. The main realizing way is special chip MB87M2140 for wired digital TV set top box. The set top box realizes validly interacting application, for example VOD.
