What are the characteristics of webcasting?

1. Real digital IP broadcasting (audio digitization - mp3, transmission digitization - computer network), where there is a network, you can quickly build a broadcast. There is no distance limitation, no transmission medium limitation (fiber, wireless, twisted pair can be used) 2) Sound quality guarantee (8k-320k variable), comprehensively improve the audio range, and due to the digital transmission, the sound quality will not change due to the change of the transmission medium, which guarantees the effect 3, simultaneous point-to-point broadcast, in the traditional broadcast To make a point-to-point broadcast, you need to pull the cable and switch to control, but even then, you can't do simultaneous multicast.

The network broadcasting system realizes simultaneous multicast through computer control technology. It is easy to test different English listening at the same time in different grades. 4. High reliability and high energy saving. The network broadcasting system adopts self-checking technology. When there is no broadcast, the working power of the system terminal is not more than 0. 3w, which reduces the safety accident rate caused by the heat generation of the strong electricity, and effectively saves the economy. energy.

5. The broadcasting has truly realized the remoteness. In places where there is a computer network, it is possible to control and use the broadcasting equipment in the authorized range to completely solve the problem of the emergency broadcasting system.

Advantages: 1 The network broadcast realizes digitalization and networkization from the production to transmission of the program. The system has high signal-to-noise ratio and will not generate noise in the process of processing and transmission, so that better sound quality can be obtained, and stereo transmission can also be performed.

2 It is easier to implement intelligent broadcasting, and Ethernet itself is a two-way network. The timing, addressing, grouping and other functions of intelligent broadcasting can be easily realized by software on the Ethernet.

3 Multi-channel broadcasting can be achieved when network speed allows. Because the audio file is in the form of a packet

It is transmitted in the network, so it is easy to implement multi-channel broadcasting, and it is enough to send different data packets to different terminals.

4 implement interactive mode broadcast and remote AOD. Because Ethernet is a two-way network, the control host can fully monitor the working status of each terminal and can control it. The terminal can also talk to the server through the LCD screen and directly from the server, which greatly facilitates foreign language teaching.

5 Convenient management: The operator can realize all the management and operation functions of the host computer by any computer on the campus network, and can also realize the production and transmission of the program on any computer on the campus.
