The heart of a video conferencing system is based on the basic components that allow the capture and transmission of audio and video signals. These components are: Video input devices - two or more video cameras / webcams or web microphones; either dedicated broadcast microphones or computers. Microphone / camera source monitor / output device - a TV or computer monitor displaying the captured signal. Audio input devices - headphones or earphones; Digital audio input device - any computer with sound card or dedicated broadcast audio software.
When considering components for a video conferencing system, consider factors such as picture quality and bandwidth. A good video conferencing service will have the latest technology in terms of compression technologies. Compression technologies enable smaller files to be transmitted and allows the exchange of more data in less time. A good compression algorithm will enable a small file to be compressed in one second. Today's internet video conferencing systems use a variety of compression technologies.
Another component of a video conferencing system is the VoIP (Voice over Internet Protocol) application. This application by logitech video conferencing enables video and voice conversations to take place through the internet between any two users who have installed the appropriate software and hardware. VoIP applications allow the users to make and receive voice calls, as well as send video calls to other users. Video calls are typically lower quality than calls made over the internet, but they offer a higher level of reliability and portability. Video conferencing also offers higher quality audio calls since many providers use a high-quality audio codec such as HEARTBEAT.
One method of compressing audio or video for transmission over a broadband internet connection is called compressing MP3. The term MP3 stands for Multipoint Digital Analog Audio compression. This type of compression uses audio channels that are independent from the digital channels used by conventional computer systems. Compressing audio allows the audio to travel at a faster rate over a broadband internet connection, which allows the same audio to be transmitted repeatedly.
An alternative to using MP3 compression is a Wideband Delayed Picture Access Method (WDI). WDI is an acronym for Wireless Digital Video Conferencing with Antenna Rejection. This method is very similar to the audio conference call, except it uses a wireless connection instead of a conventional broadband internet connection.
Other elements of a good video conferencing system include a good video display and the capability of the telepresence video conferencing system to allow participants to see each other. The display should be large enough to accommodate everyone who is attending the meeting. It should also be portable, and easily adjustable in size so that it will be suitable for different groups of people. Some telepresence video conferencing systems will also contain a feature that allows a video conferencing participant to make their presentation on a larger screen. This makes it easier for people on the receiving end to view the video and for the presenter to ensure that they are seeing everything that they will be discussing during the teleconference.
