The most common way we now have exposure to video conferencing via instant messengerprograms. Instant Messenger programs such as Yahoo, AOL and MSN have video-conferencing feature for many years. This same concept has allowed the industry to help facilitate communications and reduce costs.
The basic technology that has allowed us to have video conferencing is the compression of video and audio programs available. This is achieved by the information that is compressed into small packages so they can bevia the Internet or dedicated lines. video and audio compression software is much improved over the last forty years, which means that the packages are smaller and can be transmitted faster and with less bandwidth. This improvement in the quality of software compression also means an increase in the quality of the sounds we hear and images we see.
Videoconferencing is used to indicate an image of tin grainy and the audio quality of a program that seemedand string.
