The future of video conferencing is here. Audio visual conferencing has developed in leaps and bounds since its inception, which arguably dates back to the late 1930s, when the German Post Office (Reich Postzentralamt) successfully set up a network in several cities. These connections were made of closed circuit television systems, which were connected by cables. Since then a technique was developed, chiefly by NASA on the first manned space flights, to link televisual information via radio frequency links. This is the sort of link, still used today, by news teams to transmit reports from faraway locations. This kind of communication is all very well and good for high profile media presenters, or space expeditions, but it can hardly be viable for businesses, educational purposes, or telemedicine practices: it is simply far too expensive. Telepresence video conferencing, as we think of it today, uses much more economical technology, and so it is much more accessible to businesses and individuals around the world.
A good visual link enables you to communicate remotely to the fullest extent possible – visually and verbally. But the road to having the sufficient level of technology to achieve this has not been simple, since there have been a number of issues that have made things tricky. In the 1980s a breakthrough was made when developers used Integrated Services Digital Network (ISDN) digital telephony transmission networks to support compressed audio and visual transmissions, with some degree of success. In the 1990s, however, video conferencing founded on Internet Protocol (IP) became available, which represented a revolution in the industry. This is because among the implications was the fact that televisual communications on personal computers was now feasible, and the race to realise a widely available software solution had commenced.
Nowadays, audio visual conferencing solutions are available left, right and centre, from the free, albeit relatively low quality, Skype and iChat webcam plugin services to high-end telepresence video conferencing firms supplying large multi-national companies. A huge range of solutions are available, and can be catered to the individual needs of any business. video conferencing is said to be the way forward for remote communications in the future, so some communications companies are competing to stay on top of the game as far as the technology is concerned. In an age where almost everybody in the western world already seems to have mobile telephones, it seems only a matter of time before we are all communicating with mobile video technology as well.
