video conferencing system
Integrated Digital Services Network (ISDN): This is a point-to-point connection, however it can be used as a multi point connection through the utilization of a separate multipoint control unit (MCU) that manages the numerous ISDN lines. There are two ISDN options from which to choose from:
Plain Old Telephone Service (POTS): Since almost every home has a phone line in it, POTS are considered to be the most readily available line through which videoconferencing can take place. The problem using POTS for videoconferencing is that with its transmission speed of 56 kbps, you are encroaching on the absolute minimum bandwidth under which you can transfer audio/video data feeds. If you have software that allows for the maximization of bandwidth through high compression rates, then POTS can be extremely functional in terms of videoconferencing. For businesses and corporations, however, it is not recommended. Cellular Networks: Imagine being stuck in traffic on your way to a meeting. You are already late, but the meeting can start without you as long as you've got your cell phone or your PDA. Cell phones and PDA's are capable of providing enough bandwidth through which IP-based multipoint videoconferencing may take place. The technology for cellular networks is still being developed. Internet: As the Internet grows more and more prevalent as a device that connects the world, its applications are constantly adapting. As with LAN's, Internet connections are other forms of TCP/IP networks and can therefore be used as a medium for video conferencing. In order to be recognized on the network, Internet users must first get their Internet service provider (ISP) to provide them with their fixed, unique IP address. In this way, you can find the computer/person whom you wish to videoconference with.
