为了解决在当今中低端轿车车载前装市场中，卫星电视接收设备兼容性较弱的问题，文中基于CMMB技术，设计了一款车载卫星电视接收系统。基于车载前装性要求，进行了主从模块设计，搭建了CMMB模块硬件接口电路，将其接收到的卫星信号转换成CVBS信号；通过主控制芯片MST717外围硬件电路的设计，将CVBS信号转换成RGB信号，并完成车载液晶显示；设计了基于电源主芯片XL1410的DC/DC电源电路和音频处理芯片TEA2025B的功放放大电路。测试结果表明，该系统完全适用于车载前装市场的要求

In order to solve the problem of satellite TV receiving equipment compatibility in the low-end car market car front,based on the CMMB technology,design a mobile satellite TV receiving system. based on the vehicle front loading requirements,the master-slave module is designed,building the CMMB module hardware interface circuit,the received satellite signal is translated into CVBS signal. Through the design of the main control chip MST717 to the peripheral hardware circuit,convert the CVBS signal into RGB signal,and complete car LCD display. The power DC/DC power supply circuit based on main chip and TEA2025B power amplifier circuit based on audio processing chip is designed. The test results show that,the system is completely applicable to the vehicle market requirements
