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.
