Campus Broadcasting Development Direction
Campus radio is a kind of low-power FM radio. Many colleges, universities, middle schools and even elementary schools have now adopted a large number of campus FM radio methods to broadcast English programs or other programs. The frequency range is usually between 76-87MHz, that is to say, ordinary The TV-accompanying radio can be received.
The broadcasting system is one of the indispensable infrastructures for every school. Although the video technology and network technology have developed rapidly in recent years, the broadcasting system is still used by various schools because of its practicality, economy and convenience. Basically, all kinds of schools in our country have a public address system, which is mainly used in various public places, such as holding school-wide activities, notices, raising the national flag, performing exercises, broadcasting inter-class music, praising advanced, and holding school-wide conferences. Wait. With the continuous development of modern information technology and the continuous popularization of multimedia teaching in the majority of primary and secondary schools, the demand for using the broadcasting system for voice teaching is constantly increasing, especially the popularization of music ringtones, the implementation of English listening tests, etc., broadcast to existing schools The system's function, capacity, sound quality, and intelligence level all put forward higher requirements.
With the acceleration of the process of education informatization and the comprehensive construction of the school-to-school project, campus broadcasting will develop in the direction of "digital, networked, and intelligent" in the future, and eventually "multi-network integration" with campus multimedia and campus network. In terms of campus information construction, most schools already have or are building an interactive closed-circuit dual-control system based on a coaxial network and a computer campus network system based on the super-five digital local area network architecture. The bandwidth of the former is 1-1000MHz, and the bandwidth of the latter is 1-100MHz. Obviously, the former has obvious bandwidth advantages, and as the technology of CabModem matures, it will be compatible with all the functions of the latter.
