Because of the high bandwidth required and limited availability, these mediums have traditionally been very expensive to create or use. The end result is that a person or organization that wishes to broadcast video content is faced with a very steep price to pay in order to deliver their signal to its intended destinations.
Because the conferencing system doesn't broadcast the content of a presentation to the audience in real time, it doesn't require an expensive "video connection" between the locations viewing a Broadcast. Instead, the connection to a Virtual Broadcast can be made over standard analog phone lines with equipment no more exotic than a modem. This is possible because the information that is broadcast is not the content of a presentation, but the control information. This includes messages for starting and stopping a video clip or navigating between slides in a slide show etc.
Virtual Broadcasts can include presentations of video, either from a hard disk using technology like QuickTime, or from video disks or video tapes. They can also include animations or Slide Shows created with desktop presentation systems, the screens or documents from any Macintosh or Windows Application, any World Wide Web document or multimedia file.
Because the Virtual Broadcasts contain Audio and High Quality Graphics, Videos and QuickTime, the overall effect is similar to that of a private Television Network. With the added effect that it is interactive and you can ask questions and vote etc.
