Video Conferencing Technology and How It Works

Video conferencing is defined as an interactive means of communications between two or more locations. The interactivity is accomplished by various means but the most common include a live video and audio feed in both directions.
Video ConferencingOther options include the use of computers for displaying slide presentations and interactive whiteboards that allow others to see what you are writing on it. Videoconferencing has been around since 1968 in various forms. Many of us received our first exposure to video conferencing by watching the NASA space missions. We saw mission control and the astronauts communicating with each other in real time. We also gained exposure to video conferencing by watching the evening news when they would have several people on live video feeds talking to each other.
The most common way today that we gain exposure to video conferencing is through the use of instant messenger programs. Instant Messenger programs from Yahoo, AOL and MSN have had videoconference capability for many years now.
This same concept has made it into the business community to help facilitate communications while reducing costs. The core technology that has made it possible to have video conferencing is the audio and video compression programs available. This is accomplished by the information being compressed into small packages so they can be transmitted over the Internet or dedicated lines.
Video and audio compression software has improved greatly over the last forty years, meaning that the packets are even smaller and able to be transmitted faster using less bandwidth.

Voice Over Internet Protocol

Voice Over Internet ProtocolVoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. In addition, wireless "hot spots" in locations such as airports, parks, and cafes allow you to connect to the Internet and may enable you to use VoIP service wirelessly.
