Outline • Introduction • What is Video Conferencing? • How does it work? • Softwares used • Comparison of the softwares • Points for Comparison. • Comparison Charts. • Conclusion

Introduction • A discussion between two or more groups of people who are in different places but can see and hear each other using electronic communications . • Using video and audio signals to link participants at different and remote locations.

What is Video Conferencing? • A discussion between two or more groups of people who are in different places but can see and hear each other using electronic communications. • Pictures and sound are carried by the telecommunication network and such conferences can take place across the world. • Plainly said, VC can be described as a telephone call with the added value of the picture of the remote person(s) on screen.

How does Videoconferencing work ? • VC offers full interactive communication with: • cameras to record images in each venue • monitors to display the images from both sites • microphones to record sound at both sites • speakers to play the sound from other sites • and a codec to encode and decode the transmitted information

What are CODECs? • CODECs (Compression and Decompression components) are Video Conferencing standards to which hardware and software developers try to conform their products • To make Video Conferencing cost effective CODEC equipment was produced so that you can receive the video signals. • What Video Conferencing does, is it takes "compression and sampling" to generate the sound signal and the picture images that are sent back and fourth. A video signal usually produces vast amount of data information.

H.323 • The International Telecommunications Union standard for videoconferencing over LANs • Endorsement of the H.323 specification has been universal among conferencing-chip and -system vendors • H.323 uses Internet protocols (IP’s) to ship video and audio packets on Ethernet networks. Since IP packets are also used as the basic exchange medium on the Internet, H.323 will enable Internet Video Conferencing without the need of an ISDN line.

Desktop Systems • This system is more suitable for individual use. It uses a portion of the PC screen and has a small static camera that normally captures one or two people in the picture. • Desktop systems are popular, because of their low costs and because they can be implemented on existing desktop PC's.
