摘要
以基于Linux操作系统的Cortex-A8内核的S5PV210嵌入式平台为核心,完成音视频采集与压缩/解压处理的设计开发,通过CP-FSK高速调制/解调器完成数字音视频微波无线传输。采用DDS和PLL完成了CP-FSK调制解调器电路的设计,结合原有的微波射频电路实现了音视频的微波无线收发。实验结果表明,系统设计合理、运行稳定流畅,满足设计要求。
In order to achieve the development of audio＆video acquisition and compression/decompression process and the microwave wireless transmission of digital audio＆video by CP-FSK high speed modulator/demodulator, a system is designed based on Linux operating system,in which the Cortex-A8 Core S5PV210 embedded platform acts as the core. The CP-FSK modem circuit is finished by DDS and PLL. Combining with the original microwave radio frequency circuit, microwave wireless transimit-receive of audio＆video is achieved. The experimental results show that the system is reasonable, it works stably and smoothly and meets the design requirements.
