The public broadcasting system in accordance with the transmission signal processing can be divided into the following categories: the traditional way is through the audio cable to the analog power signal is transmitted to the terminal speaker to speaker in the engine room of the power amplifier is the use of high transmission, general is 100V or 70V, the advantage of less line losses, convenient load connection, but the speaker with a step-down transformer and connected to the line. CNC way the true meaning of Digital Addressable public broadcasting system that audio signals, control signals and communications all in the digital domain, with a transmission distance farther and better transmission effect, especially the audio signals and control signals concentrated in transmission over a two-wire twisted pair. IP network broadcasting is based on the Internet and LAN network of pure digital audio broadcasting system, different from the traditional analog audio, FM, addressing, and numerical control of a broadcast system, streaming media (IP) intelligent digital broadcasting system is fully compatible with the Internet and LAN, Application of TCP / IP protocol, without further wiring, can make use of the existing campus network or intranet; embedded hardware terminals, can be set independently of the IP address, through a multi-layer switch, the host can arbitrarily control the settings on each terminal and play, but you can select the desired content on the terminal; the use of computer technology, the system is compatible with almost all audio formats, using IP technology, broadcast content without any restrictions, each terminal can be arbitrary Play desired content. It can completely replace the traditional intelligent broadcasting system based on analog or digital, the real Internet or LAN-based IP audio broadcasting capabilities to support broadcast, live, on-demand, etc., some of the products support full-duplex two-way intercom, terminal lectures and other functions, and It supports a wide range of popular applications.
