| "Twelfth Five-Year" period, China’s rapid development of radio and television broadcasting, Radio and television technology systems also will be a qualitative leap, Different types of programs broadcast transmission method increasingly digitized, diversification, Broadcast transmission modes of various programs increasingly digital, diversification, And between the various ways can permeate each other, complement each other, to better achieve the full range of transmission coverage, Effectively to ensure that the radio and TV security broadcast. In this paper, by introducing the provincial radio and television signal transmission network project construction situation in our province, This paper expounds in detail the microwave, optical fiber, synchronous digital hierarchy (SDH) digital core technology, and its application in radio and television industry, In-depth study the use of microwave and fiber optic technology mix of self-healing network feasibility, A detailed analysis of the current situation of radio and television transmission network at the provincial level in our province, Actual demand for new radio and television transmission tower signal transmission system, Planning for new radio and television transmission tower signal transmission system microwave fiber hybrid network structure, Design the detailed project implementation plan, The various interfaces, jitter, SNCP etc transmission ring network performance testing, And according to the test results, Proved that the implementation of the.project can well solve the problem of new radio and TV tower signal source, Verify the use of digital microwave and fiber optic technology consisting of a mixture of self-healing radio and television signal transmission network can be achieved, And reliable performance, safe and stable, self-healing force is strong, Can be more effective to ensure the safety of our province provincial radio and television programmes broadcast. |
