Did you know you can use many instant messengers for
video conferencing?
Historically, the major expense in establishing a video
conferencing system has been in the video technology,
which requires a video camera, video display, and a fast
data connection. Because of these requirements, video
conferencing has been quite expensive until recently.
In recent years, IP (internet protocol) based video
conferencing has been overtaking traditional ISDN-based
systems. Internet video conferencing has the advantage
that it is accessible to anyone with an internet
connection and a webcam. In addition, it becomes possible
to integrate live video with a web conferencing tool,
allowing for a much richer multimedia environment for live
meetings and presentations.
Video conferencing can be used as an imperfect substitute
for many face-to-face meeting requirements where the cost
or time required for physical transportation of parties is
undesirable. For instance, interviews with job applicants,
business meetings, and lectures can be conducted
effectively via video conference.
For business purposes, the current preference is for the
use of private or virtual private network (VPN)
connections for IP video teleconferencing which guarantees
better performance and transmission security. Local area
network infrastructure provides for high-bandwidth
communication suitable to the application of video
conferencing technology.http://www.ivci.com/
