5.1.5.1.5 Videoconference
Table 5-5 Suppliers of E-Learning service
The Videoconference is an interactive communication way that allows two or more people to
communicate in different places, with audio and image communication and in real time. It
has also been called visual collaboration and is a type of groupware. It differs from
videophone in that it is designed to serve a conference rather than individuals.
The core technology used in a videoconference system is digital compression of audio and
video streams in real time. The hardware or software that performs compression is called a
codec (coder/decoder). The resulting digital stream of 1's and 0's is subdivided into labelled
packets, which are then transmitted through a digital network of some kind (usually ISDN or
IP). The use of audio modems in the transmission line allow for the use of POTS, or the
Plain Old Telephone System, in some low-speed applications, such as video telephony,
because they convert the digital pulses to/from analog waves in the audio spectrum range.
