Radio And Television Broadcasting Fault-tolerant Design And Implementation Of System Data

With the continuous development of digital technology, broadcast and television is facing a new era. Not only convert programs from analog mode to the digital ,but also change entirely for broadcasting businesses. Broadcasting plays a crucial role in technical layer. However, broadcasting content and mode have been changed completely.Broadcasting system is transiting from traditional and manual to digital and automatic hard drive broadcasting way, which integrates multi-media, database and network technology to increases memory and enhances transfer rate. On account of rising programs and enriching contents, the broadcasting systems at present remain to be perfect. It is necessary improve targets basing on different types and structures. At present, real-time broadcasting requires that inactive time is less than few seconds. Therefore, a safe and reliable broadcasting system is designed to consider. To ensure uninterrupted broadcasting and timely resumption of error, developers need to account full of a serious of fault-tolerant mechanism, making system has good safety, reliability and fault-tolerant.The issue stems from Digital Audio Broadcasting System. The current status and the lack of broadcasting system are first analyzed. Then this project developed a multi-path distribution from the database of detection , fault-tolerant for preparation of the mian file server and fault-tolerant database for broadcasting system. It has done a detailed exposition from design to realization. The subject of study for high-speed data system also has value.The Digital Audio Broadcasting System has been provided to Tibet Radio for using. So far, performances are excellent and stable, which affirmed the results of this issue.
