Video conferencing systems



Solutions

Video conferencing connects individuals and groups at two or more different locations through telecommunication networks. Using video technology, it enables them to see and hear each other, like they are at the same room. A higher degree of efficiency in team work is achieved through video conferencing, because it allows integration with other electronic services (data transfer, mutual work on applications etc.), which are increasingly playing a more important role in everyday life.

Application of video conferencing

Business sector Primarily, video conference is a right solution for companies which require holding frequent meetings between participants on different, remote locations. In modern business systems, where one of the main priorities is the team productivity, it is necessary that the qualities of the picture, especially of the sound during the “distant” meetings are on a high level.
Health Video conferencing opens the possibility of connecting medical institutions on different territories, consultations between doctors, experience exchange, tele-diagnostics and “distant” councils. It allows geographically remote medical institutions to have access to expert medical resources, personnel education, consultations and help with diagnostics.
Educational institutions The possibility of connecting academic institutions between themselves. Emitting of events that are important for academic community. Participation in lectures, conferences, vocational assemblies, round tables and “distant” seminars.
Ministry of justice, government organizations and non government organizations

 

Main conveniences of using video conference are:

• Fast and simple data and knowledge exchange
• Faster decision making, timely response to market demands
• Money and time saving
• Reputation rise

 

Depending of the number of participants and the size of the conferencing room, video conferencing systems can be classified into tree groups:

 

DESKTOP - for personal use

Desktop videoconference delivers communication and presence to important meetings on any location from the convenience of your PC

GROUP SYSTEMS

Group video conferencing systems are predicted for smaller groups of people in smaller conference rooms

                    

LARGE CONFERENCING ROOMS

Group systems are predicted for great audiences in large rooms and amphitheatres. Integration in complex audiovisual surrounding

                     

TECHNICAL PREREQUISITES FOR VIDEO CONFERENCE REALISATION AND MAIN TECHNICAL CHARACTERISTICS:

Basic technical prerequisites for video conference realization are the computer monitor, TV or projector and quality Internet connection or towards a public telephony network via ISDN adapter. Because of the constant advance in the telecommunications infrastructure in our region, in the way of network availability and advance technology usage, and since almost all potential users today have personal computers and a video displays, technical prerequisites already don’t request a lot of investment. These reasons and the fact that video conferencing brings many advantages, don’t leave a lot of space for worry in the future of this communicational system.

 

 

TeleGroup in its solutions secures video conferencing connections with network access over IP, prime or base ISDN interface as well with a support for V.35 connection. Internet network solutions and those using IP are done using standard signalization protocols H.323 and SIP. Because of the need for maximal reduction of the transfer capacity, digital video signal is compressed using the most modern algorithm H.264 – securing a high degree of compression with quality preservation of the reproduced signal, as with the professional television systems. For those users who need system protection and defense against possible “intrusions” in the communicational channel video conferencing system gives the possibility of AES encryption. Besides that, TeleGroup solutions use movable PTZ cameras, system for following direction of speech, dual monitor support as well as dual camera and dual microphone, support for recording and reproducing audio-video material etc.
