Abstract: This paper developed a network video server based on Freescale video processing chip IMX27 running on the Linux operating environment, and short connection was used to complete the interaction between the server and clients, which effectively saved system resources and reduced the CPU utilization of the sever. Moreover, in order to obtain high quality video images, the server adopted an adaptive de-interlacing algorithm based on the use of splicing and interpolation of static and moving picture respectively to realize de-interlacing of the video image, therefore the integrity of the video data was guaranteed and the video clarity was improved. In the end, an application case of the server was given, which achieved the desired designed goal.
