摘　　要：设计了Linux系统平台下,利用摄像头进行视频采集,采用先进的MPEG-4视频压缩标准对所采集的信息进行压缩,然后通过GFSK发射芯片,将信息发送到另一基于ARM核的嵌入式芯片所控制的液晶显示屏上。系统测试表明,本系统能实现视频的采集、压缩、传输及远程显示,从而实现无线监控,且系统具有稳定性、可移植性,十分适合嵌入式应用领域。This design is based on the Linux platform, and uses the camera for video capture and advanced MPEG-4 video compression standards to compress the information collected, then uses the GFSK launch 2.4G chips to send information to another ARM-based core embedded chips under the control of the LCD screen, enables wireless control. This system enables video capture, compression, transmission and remote display to achieve wireless monitoring. And the system is stability, portability, and very suitable for embedded applications.
