For a videoconference to take place, both parties must have audio-visual equipment (monitor, camera, microphone, and at least one speaker) as well as a means of transmitting information between sites. As you can imagine, a broadband satellite connection with studio-quality equipment produces an excellent full-motion video connection, but the equipment and transmission expense is great. Recent advances in computer and telecommunications technologies have sparked an interest in compressed video systems, which transmit information via today’s Internet or telephone network, greatly reducing the cost of videoconferencing.
Videoconferencing connections may be limited to a closed network (such as a LAN) or may use public networks (such as regular phone lines). Many videoconferencers connect via ISDN (Integrated Services Digital Network) because it is an economical solution for high-quality videoconferencing. ISDN works over regular telephone lines, transmits at 128 kbps per line, and provides dedicated bandwidth for smooth audio and video (15-30 frames per second).
There are several websites that provide media professionals with desktop videoconferencing services, including, Windows NetMeeting (www.microsoft.com/windows/netmeeting), PictureTel (www.picturetel.com), and VTEL (www.vtel.com). However, Eloquent (www.eloquent.com) seems to provide the best blend of technology and service.

Although nothing may ever replace a handshake and “face-to-face” meeting, desktop videoconferencing is an interesting alternative for those I-just-can’t-get-there-today situations.
