摘要
设计了一个基于机顶盒的多媒体共享系统,详细介绍了系统的实现原理、硬件构成和软件设计。系统由发送和接收2个模块构成,运用无线传输红外遥控信号和射频信号,有线传输AV调制信号相结合的方式,抗干扰能力强、信号稳定,有效地实现了多媒体资源的共享。
A shared multimedia system based on STB is designed. Realized principle, hardware constitution and software design were introduced in detail. This system is composed of two models of sending and receiving. By the combination of wireless transmission of infrared remote control signal and radio frequency signal and cabled transmission of modulated AV signal, it has a strong resistant interference ability which can realize the multimedia sharing effectively.
