Webcasting disadvantages
Network broadcasting is an important manifestation of the form of multimedia transmission on the Internet, and also an important manifestation of the online development of radio and television media. For traditional broadcasting, network broadcasting is a supplement to its functions, and the two are complementary and cooperative.
Disadvantages: â‘ Expensive: For the decompression of digital audio files, it must be PC+ special software or a special decompression chip, and each terminal must have its own IP address. At present, there are no professional chip-level developers in China, and they can only use embedded microcomputers + dedicated decompression chips to decode, which results in high product prices that ordinary domestic schools cannot afford.
â‘¡It is easily restricted by network bandwidth and network speed. The campus network is a comprehensive public network. For schools, it may also be used for educational administration, multimedia teaching, e-library, and distance teaching. Ethernet uses code division multiple access technology. When a certain node has "network traffic", the broadcast terminal's broadcast will be delayed, and in severe cases, intermittent will occur. Because of the above reasons, the reliability of network broadcasting is difficult to guarantee.
