Webcast advantages

Network broadcasting is an important manifestation of the multimedia form of network transmission, and also an important manifestation of the online development of broadcast and television media. As far as traditional broadcasting is concerned, network broadcasting is a supplement to its functions, and the two are complementary and cooperative.

Broadcasting refers to a news dissemination tool that transmits sound through radio waves or wires. The program that transmits programs through radio waves is called wireless broadcast, and the program that transmits programs through wires is called cable broadcast. Broadcasting was born in the 1920s. The advantage of broadcasting is that it has a wide range of targets, rapid spread, diverse functions, and strong appeal; the disadvantage is that it is fleeting, listening in order, no choice, and difficulty in listening if the language is not clear.

1. Many broadcast zones

2. Many programs

3. Many sub-control sites

4. Fast system construction

advantage:

1. It is relatively easy to realize intelligent broadcasting. Ethernet itself is a set of two-way network. The timing, addressing, grouping and other functions of intelligent broadcasting can be easily realized by software on the Ethernet.

2. From program production to transmission, network broadcasting is fully digitized and networked. The system has a high signal-to-noise ratio and will not generate noise in the processing and transmission links, so that better sound quality can be obtained, and stereo transmission can also be carried out.

3. When the network speed allows, multicasting can be realized. Because audio files are in the form of packets

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

4. Convenient management: The operator can realize all the management and operation functions of the host as long as any computer on the campus network, and can also realize the production and transmission of programs on any computer on the campus.

5 Realize interactive 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 order from the server, which greatly facilitates foreign language teaching.
