The development of televised open lectures for the public by major universities, of extension course programs by regional CATV broadcasting companies, and of televised lectures for use on campus video networks have all recently become growing trends in various parts of Japan. In this paper, the authors present a tentative proposal for guidelines for developing 30-minute university-level open lecture programs. Their guidelines encompass two types of programs, types which can be characterized as either flip- or time-structured. Generally speaking, the flip model has four major characteristics : (1) each 30-minute program contains nine or fewer flips, (2) each flip is less than 120 seconds in length, (3) each flip is shown repeatedly, but no more than eight times in total, and (4) none of the shots last more than 20 seconds or so. The second, time-structured model closely follows the structure of traditional university lectures, i. e., they have four main sections (introduction, development, shift and conclusion). The introduction lasts for about three minutes, the development for around 20 minutes, and the shift and the conclusion last for perhaps two and one-half minutes each. In addition, there are four 30-second intervals : one between each of the major sections and a final one at the end of the program.
