| Abstract: | 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. |
