What are the main problems in videoconferencing?
- There are two. The first is that communication channel for transferring audio and video information shoud be wide enough. Usual telephone lines are good for audio but cannon provide quality video. But LAN is very good network for videoconference.
The second problem is processing of video and audio stream: coding and decoding of transferred data. The reason is that videoconferencing includes very high compression ratio algorithms especially for videostreams. If computer power is not sufficient for this algorithms, dropping of videoframes, jamming of audio can arise and so on.
