From the traditional broadcasting system to the broadcast network is a turning point in the development of the broadcasting system. The network transmission can guarantee the quality of the audio transmission and the type and flexibility of the program; it is generally used in large buildings, schools, airports, stations and other areas.
Networked broadcasting needs to avoid adopting networked public broadcasting for digitization, understand what type of network is used to understand the design parameters of the network system, and set priorities according to the project conditions.

The networked broadcasting system consists of a network broadcast control heart, a network terminal, a network paging microphone, and a network consumption interface. Compared with the traditional broadcast that can only be controlled centrally by the computer room, the interactive function, partition, and group can be arbitrarily combined.
The wireless broadcasting system has taken another step in the networkization, mainly improving the early warning capability of the remote mountainous areas and rural information ends, and adopting the combination of the backbone network frequency modulation and the terminal wireless coverage, which can solve the problem of comprehensive coverage well. There are multiple levels of linkage that can be controlled.

All towns and towns use wireless FM transmission to transmit signals to various administrative villages. One day, the broadcast controller is mainly used. The emergency broadcast signals from the county level are taken out from the closed-circuit television system, and the emergency microphone signals, audio signals, and control data signals are passed. The mixing of the internal hardware of the controller and the prioritization of the program. It is sent to the transmitter on the mountain through a dedicated audio optical transceiver, and finally reaches the administrative village through the transmitting antenna.

High-definition broadcasting system: There are many people in various railway stations and subways. The sound clarity of general broadcasting systems cannot meet the requirements, and the high-definition broadcasting system was born for this purpose. The general high-definition broadcasting system mainly develops strong directivity, high power, high-band sensitivity, slow out-of-band attenuation, and high speech intelligibility in the single speaker and speaker.

With the development of the times, people's needs are bound to become more and more detailed, and the products that follow will naturally need more and more attention to detail.
