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.

Conclusion Cu-Seeme was the best , then came Netmeeting. Honeycom the worst software specially for
dialup and cable connection to New Jersey. All softwares did not work with router , worked
without router.
