With the development of internet technology, traditional radio stations are affected by the great influence from web media. After investigation and research on broadcasting industry, traditional radio begins to shift towards new media broadcasting. The current streaming media server fails to switch automatically among multiple audio sources. Furthermore, it is insufficient in control functions and broadcast delay. A new media broadcasting server, against the deficiencies of the current streaming media server mentioned above, is implemented which meets the requirements of new media. We firstly introduce the current researches and applications of streaming audio server and illustrate the specific requirements of the broadcasting industry to the new media broadcasting server. Then we describe the functions of the new media broadcast sever and analyze circular buffer method for thread synchronization model, automatically switching the audio source and remote control method in detail.Finally, the functions and performance of the server are evaluated with experiments. The experimental results show that new media sever reaches the user needs and commercial purposes.
