中文摘要：
提出了一种适用于数字电视机顶盒的2．4G无线音频收发系统的设计方案。该系统以nRF2421芯片为无线音频处理核心，用于模拟／数字音频信号的处理及传输。发射端以单片机为主控芯片，用于控制nRF2421状态、音量调节和配对等功能。系统结构简单，接收端小巧便携，并结合实际需要提出了一种便于生产和售后维护的配对方法，为解决家庭娱乐干扰问题提供了有效的解决方案。
英文摘要：
A design scheme of 2.4 G wireless audio transceiver system for digital TV set-top box is proposed in this paper. nRF24Z1 is the wireless audio processing core of this system, it is used to dispose and transmit simulate/digital audio signal. The MCU is the master chip of ATX modules, which is used to control the state, volume adjustment and matching of nRF24Z1. The system structure is simple, the receiver is small and portable. And it provides a matching scheme which is convenient for production and after-sales maintenance in order to solve the interference problem of family entertainment providing effective solution.
