One example of successful deployment of video conferencing is in the telemedicine field. In this manner, doctors in different locations can collaborate in a manner in which they can see each other, all see the patient, and all look at the same data to assist in their discussions. This is particularly useful for smaller facilities that do not have the same resources as the larger research hospitals, or rare medical problems that require access to one of a small group of experts around the world. Interactive distance learning is another application which requires successful deployment of a video conference system. In this environment generally the teacher will be in one physical location while the students are in another, although the students could be in multiple locations.
Additional displays are necessary for data, such as an electronic whiteboard or a computer terminal.
Due to the interaction necessary in a classroom it is required that the audiovisual quality be high and the time delay be low, such that focus is not taken away from the subject material. Low budget television stations have begun to use video conferencing technology to interview guests for talk shows or news interviews. The quality is not as good as a satellite feed but the cost is dramatically less, and the access may be a lot easier. Of course the corporate environment will form a large contingent of video conferencing users. Corporations often have the infrasturcture necessary to deploy a video conferencing system and can justify the cost of the system through decreased travel expenses.
