Definition of Videoconference
Videoconferencing is a two-way audio, video and data communication system in real time and by telephone with the aim of linking two or more geographically distant points, allowing interaction between different people or work groups. This requires the use of specialized equipment that is placed in conference rooms using broadband communications. When a video conference is held for informal purposes, it is called a video call or video chat.
This technology is especially convenient for business users located in different cities or even different countries, since it saves expenses and inconvenience of mobilization, lodging and stay.
The videoconference involves the preparation of the digital signal, the digital transmission and the processing of the signal that is received. When the signal is digitized, it is transmitted via terrestrial or satellite at speeds between 64 kbps to 2 Mbps.
In order for the videoconference to take place, the image must be compressed using the CODEC. The data is compressed in the source equipment, travels compressed through some communication circuit, either terrestrial or by satellite, and is decompressed at the destination.
What is it for?
The main advantage of the videoconference is that the participants can see each other, which allows to develop stronger relationships between relatives or acquaintances who are in different cities or countries. In the work environment, it is used to carry out negotiations, agreements and even interview candidates.
Multipoint video conferencing allows three or more participants in a virtual conference room to communicate as if they were sitting next to each other.
