摘　　要：针对高清数字机顶盒面向家居智能化的发展趋势,设计了基于STIH416芯片与Android操作系统的智能数字机顶盒系统。嵌入式智能数字机顶盒相比传统机顶盒,其在解码能力、功耗、数据流处理以及平台拓展性方面都具有独特的优势。该文就机顶盒系统总体结构进行了介绍,硬件平台方面,对网络接入模块、条件接收系统以及红外接收模块进行了重点设计;软件方面,以Android操作系统为核心,采用松散耦合便于扩展的分层式设计。最后介绍基于移动平台的机顶盒控制端的软件设计。In view of the home intelligentized development trend of HD digital set?top box(STB),an intelligent digital set?top box system with STIH416 chip was designed on the basis of Android operating system. The embedded intelligent digital STBset?top box has more advantages in the aspects of decoding ability,power consumption,buffer?processing and expansibility ofsystem,compared with traditional one. The overall structure of set?top box system is introduced in this paper,especially for thedesign of network access module,conditional access system and infrared receiving module. The Android operating system is tak?en as its core. The loose coupling is adopted for better expansibility of hierarchical design. In the end of the paper,the softwaredesign of the set?top box terminal control based on mobile platform is introduced.
