A Test of Four Slow-Scan Television Systems for Remote Teaching.
Peters, Donald Creswell, Jr.
A study to evaluate four different black and white slow-scan television (SSTV) systems as information delivery systems was conducted using four classes of university students, one at the graduate level and three at the undergraduate level. Each class viewed videotaped examples from the four SSTV systems during one class period, and were asked to rate various physical characteristics of each system, using a questionnaire, and to then rank the systems in order of preference. Faculty members attended demonstrations which featured one of the SSTV systems, and were subsequently interviewed to determine their perceptions of the systems. Results indicated that students preferred a top-to-bottom scan, medium resolution, and a frame time of 8 to 10 seconds; they ranked the Robot Model 630 as most desirable. Interviews with faculty indicated that, while they accepted the concept of SSTV, all but one had no immediate application to their respective areas. The appendices include the script of the test program, the student questionnaire, a comparison of the SSTV systems, and a tabulation of voice and videocircuit transmission costs. Thirty references are provided. (Author/BK)
