摘要
该系统是以Linux作为操作系统,并以S3C6410微处理器为硬件平台的嵌入式应用系统。系统采用CMOS摄像头获取图像,通过WiFi无线传输;利用S3C6410独特的MFC功能,实现H.264高速、高效率硬件压缩和解压;通信双机采用多线程方式实现了音视频实时传输;可在4.3寸的彩色液晶屏上显示本机及远端机清晰的图像;音频与视频可全双工同步传输。该系统功能实用、操作简洁,能够广泛应用于小型音视频服务或网络音视频电子产品,可替代传统对讲系统。
The system takes Linux as the operating system,and uses S3C6410 microprocessor as the hardware platform of embedded application system. The images are obtained by CMOS camera and transmitted through WiFi. H.264 high speed,high efficiency hardware compression and decompression are realized with MFC function of S3C6410. The audio and video real-time transmission of two computers communication is realized through multithreading,thus the clear image of the machine and the re-mote machine can be displayed on the 4.3-inch color LCD screen,and the audio and video can be transmitted in full-duplex syn-chronous. Function of the system which can replace traditional intercom is practical,operational,and it can be widely used in small audio and video service or network audio and video electronic products.
