With the development and improvement of the streaming media technology, the traditional streaming media server has been unable to meet the needs of public. In order to improve the capability of the streaming media server, we designed and implemented a recording clip server, which is separated from the traditional streaming media server with analysis the function and structure of traditional streaming media server. We use the modular design approach to implement the corresponding function modules. It ensured that the real-time received of media stream, the right clips and backups of media stream and worked high stable and synchronization. This paper intends to design a recording clip server which could work stable and have good performance by the combination of theory and experiment.
