Compressed video is a two-way video system providing video and audio communications in both directions between learners and instructors. Each location has cameras, microphones, and monitors. Compressed video is transmitted over telephone lines. One of the reasons compressed video works for training is learners at a distant site come from the same community and share common backgrounds. Because volunteer programs are often taught by several instructors, it is the responsibility of a class facilitator to make the distance education process easy for the visiting instructor each session.
Success begins with careful planning .
The logistical difficulties increase with every added video site. Most Extension personnel, volunteers, and outside instructors are not technologically trained in the use of compressed video. Success in distance education is due more to preparation than innovation. Ensuring sound quality and avoiding distractions. The primary need is for students to learn the subject matter.
