Two-Way Interactive Videoconferencing Services       
Two-way interactive videoconferencing has been used at the Dartmouth-Hitchcock Medical Center since 1968. The institution was a pioneer in this field with its Interactive Television Network, commonly know as Interact. At that time, the system was a microwave based, full motion system that connected seven hospitals and prisons in Vermont and New Hampshire.

   Today, Videoconference Services operates Dartmouth-Hitchcock's multi-point interactive system. Anywhere from two to seven sites can participate in a videoconference and can see and hear each other. All conferences use compressed video technology with Tandberg, Lifesize and Polycom videoconferencing equipment.
   Videoconferencing is used for administrative meetings, distance learning, telemedicine and medical presentations.  See the Continuing Medical Education schedule for a complete listing of upcoming CME programs.

Streaming Videoconference Services

    This method of videoconferencing transmits the video/audio and PowerPoint information over the world-wide-web to a PC or to a PC in an auditorium. Videoconference Services normally uses Media Player and Flash for its video streaming. At DHMC we transmit audio, video of the speaker and PowerPoint slides simultaneously in a browser window. Lectures can be view live or as an archive.


    Podcasts are audio or video streams that can be played on iPods or mp3 players. The medical center has several podcast portals on iTunes that allow people to download lectures to their iPod. They can also be accessed via
Podcasts are popular because they are so portable and are used for archived lectures.

Web Conferencing

    Many videoconferences are available over the web. Using your browser, simply go to the URL offered for the conference. Anything from the presenter's computer appears on the screen automatically. Some web conferences allow for viewer polling, electronic chat and file transfers during the conference. It is great for collaborative meetings as well as lectures. Although video is not generally used, the proliferation of webcams now allows for two-way and group videoconferencing while in a web conference.
    Audio may be heard either by dialing a toll free number or VOIP connection (voice over IP). DHMC currently uses WebEx as their web conferencing solution.
    Web Conferences can also be recorded.
