The future of video conferencing has arrived. Audio visual conferencing has progressed in leaps and bounds since its inception, which arguably dates back to the late 1930s, when the German Post Office (Reich Postzentralamt) successfully created a network in several cities. These connections featured 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 using radio frequency links. This is the type of link, still used today, by news teams to deliver reports from distant locations. This kind of communication is all very well and good for high profile media presenters, or space expeditions, but it can scarcely be viable for businesses, educational purposes, or telemedicine practices: it is simply far too dear. 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 throughout 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 easy, since there have been a number of difficulties that have made things hard. 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 amount of success. In the 1990s, however, video conferencing built on Internet Protocol (IP) became available, which amounted to a revolution in the industry. This is because among the implications was the fact that televisual communications on personal computers was now a possibility, and the race to release a widely available software solution had started.

Today, 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 dealing with 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 global 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 virtually 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.
