Abstract: Ordinary cameras output images in analog mode (PAL or NTSC format), forcing digital video application systems to use PCs to digitize images through acquisition cards. In order to minimize the interference in analog video transmission and avoid the loss of image details during the process of encoding, analog transmission, and re-decoding and digitization, a micro-embedded digital video server based on an embedded Linux system using compression chips and high-efficiency network chips is proposed to solve the problem of real-time compression and transmission of large amounts of audio and video streams. The digitization of images is moved from the computer end to the camera end, and the digital video obtained by the digital camera or the analog video of the ordinary camera can be compressed into MPEG streams, packaged, and transmitted via Ethernet.
