摘　　要：针对现用有线数字电视机顶盒按一户一台配置,仅输出一路信号,不能满足一户有多台模拟/HDTV电视机使用需求的问题,拟定了基于模拟/HDTV电视机多路信号处理、多台高清晰度数字(HDTV)电视机射频信号处理和无线传输信号处理的3个设计方案。并对整机设计思路、结构、工作原理、特点和实现途径等进行了简要阐述,为有线数字电视机顶盒的推陈出新提供了思路。For now with cable digital TV set-top box to press a door a configuration, only output signal all the way, and unable to meet a family have many sets of simulation/HDTV television use demand, drawn up based on simulation/HDTV television signal processing, more than many sets of high definition television （HDTV） digital RF signal processing and wireless transmission signal processing three design scheme. And the design idea, structure, working principle, characteristics and implementing way, this paper discusses the cable digital TV set-top box for the advent of the given.
