Research on the Communication Method of Broadcasting and Television System Based on Digital Transmission Coverage Technology
At present,the coverage identification structure of radio and television system is most-ly independent,and the implementation coverage range is limited,leading to a decrease in the proportion of coverage.Therefore,the communication method of radio and television system based on digital transmission coverage technology is proposed.According to the changes of cur-rent test requirements and standards,the basic digital transmission coverage exchange signal fea-tures are extracted,and the multi-level method is adopted to break the limit of execution cover-age and set the multi-level coverage identification structure.Based on this,the communication model of digital transmission coverage technology is built,and the communication range of broadcasting TV system is improved by multi-carrier integration.Final test results show that:compared with the application of traditional wave separation technology in broadcasting and tel-evision system test group,the traditional IP digital microwave technology in the broadcast and television system test group,the design of the digital transmission coverage technology can reach more than 3.2,shows the current design of radio and television digital transmission coverage structure more flexible and changeable,can effectively improve the stability and reliability of broadcasting and television system communication,expand the scope of broadcasting and televi-sion system communication,has the practical application value.
