With the rapid development of computer network media,the research of real-time video compression and trans-mission technology has very important significance. The H.264 real-time video compression and transmission system based on Ubuntu Linux operating system was established. The software and hardware implementation methods of the system,and the de-sign concept of the system structure are introduced in detail. The acquisition and coding module of real-time video is used to de-sign the system,in which the execution codes are adopted to achieve various modules. The results show that the transmission of the system can obtain better image quality and lower transmission delay,which can meet the demands of real-time application.
