| Satellite digital TV is an important part of satellite communication business. Use of live satellite transmission that digital TV and radio programs to the public, is to improve the transmission quality TV programs to expand coverage of the most effective and economical as a means. It is twenty years in radio and television broadcasting in our country to flourish and widely used, and in the construction of socialist material civilization and spiritual civilization plays an important role.With the rapid development of Satellite digital TV services in China in these years, the departments who monitoring the signal and the services quality have paid more and more attention to the interference of that. To protect the program broadcast safety, it should be a primary problem that makes the interference distinction quickly and accurately in the field of satellite signal monitoring and TV services quality monitoring, as the satellite wireless communication link is more susceptible to the impact of various factors.In this article, the author lists the possibility that interference occurs in the synchronous satellite communication link, expounds a logic idea for distinguishing the interference make use of multi-parameter, provides a quick and accurate solution for the interference distinction, and then conducts the feasibility analysis of this solution which base on the practical application.Firstly, from the application and technology point of view related to the satellite digital TV make a comprehensive introduction, then the current domestic satellite digital TV interference described the current situation, thus allowing readers to fully understand this article discusses the background of the system and its role in project implementation. Secondly, according to the characteristics of satellite digital television cited several of its possible interference, as well as means by which these different interference situations accurately identified.Project solutions in the system, the paper made a number of innovative key technologies to construct a reasonable platform, the platform can be fully guaranteed without discrimination of satellite digital television interference missing, while minimizing false positives RatePrograms in the system implementation of the project, the paper on digital satellite TV signals from the monitoring, analysis and judgments, the data storage management, the release of alarm information, and several other aspects of the detailed description, and lists the items that the system can achieve Functional indicators.Finally, from a construction point of view, points of hardware, software, two items construction details of the system were introduced, and the actual application of the project summary. |
