Audio/Visual Ratios in Commercial Filmstrips.
Gulliford, Nancy L.
Developed by the Westinghouse Electric Corporation, Video Audio Compressed (VIDAC) is a compressed time, variable rate, still picture television system. This technology made it possible for a centralized library of audiovisual materials to be transmitted over a television channel in very short periods of time. In order to establish specifications for equipment design, existing commercial audiovisual programing was evaluated to determine the length and the number of picture changes in a typical commercial program. Characteristics of 4,000 titles from 27 companies were surveyed and coded to grade level and subject area. Statistical tables and graphs show the distribution of surveyed programs by subject and grade level. Graphs and additional material relate the characteristics of the surveyed commercial filmstrips to the VIDAC technology. (Author/DS)
