A Video Conferencing system is required to see and talk to people in real time. Its like a conference call, but its possible to see the persons as well as talk to them. In addition to that, participants can also show a presentation to the other end while talking. This is very useful for conducting business meetings, educational seminars, tele-medicine, multi-location discussions, etc without the people involved having to travel all the distance!
In the above architecture diagram, there is a head office with three departments (IT Dept, Dept-1 and Dept-2) with LAN connectivity between them. There is also a branch office and remote location (for tele-commuter). All these different locations have some form of connectivity – either all of them are connected over Internet Leased Lines or have MPLS network set up between them, etc. So, using VC-1 and VC-2 and the IP Network, the people from Head Office IT department can see and talk to the people from the Branch office. Also, the person from the remote office/ home worker can dial in to the conference by using a software VC client on his laptop and connecting to the internet using a broadband connection. That becomes a 3-Party Video Conference. There could also be another monitor connected in each location where they could see a presentation (ppt slides from computer) being presented by the remote user.
What are the components of a Video Conferencing System?
Video Conferencing Codec/ Camera (This is the heart of the VC system as it integrates multiple input streams with the output streams – audio and video. The Codec also compresses the video data with a technique called H.264 which enables better quality at a lower bandwidth. There are even High Definition Video Conferencing systems for better clarity, now. The VC Codec generally comes with the required camera and microphone(s).
Display Devices – A CRT TV, LCD TV, LCD Monitor, Plasma Display. Do note that some of them may not have built-in speakers and hence a basic amplifier and speaker system would help.
Bandwidth – A Video Conferencing system is used to conduct a meeting between two disparate locations and hence both the locations need to be connected with each other using Internet Leased Lines, Point to Point Managed Leased Lines, MPLS networks etc.
PC/ Laptop – To make presentations that can be visible at the remote end by connecting them to the VC System. Even a DVD player/ Document camera can be connected to the VC system and their output can be seen at the remote location.
Latest developments in the Video Conferencing Industry:
High Definition – Video Conferencing sessions can now be viewed in high definition mode if the VC system, monitors and other accessesories used are HD enabled.
Recording and Streaming – Video Conferencing sessions can be recorded and played back at a later stage They could also be streamed to a number of LAN users live so that they could also see and listen to the speaker.
Telepresence – Video Conferencing cannot get more real than telepresence. This is a method where the the images presented to the participants are Tenveo and the room is designed in such a way that half the table appears to be on this side and the other half appears on the screen – All this create an illusion to the user that the remote participants are sitting just opposite to them.
