A study was prepared for the Department of Health, Education, and Welfare (DHEW) on the role DHEW could play in the implementation of instructional television. This volume of the study provides a detailed description of alternative delivery systems. It analyzes the different technical capabilities and component costs of a variety of distribution system configurations including cable television, pay television, closed-circuit television, video disc, video tape, UHF broadcasts, microwave systems, satellite systems, and computer-assisted instruction systems. A basis for cost comparison is then described. The report notes that while costs for procurement and distribution of program materials or services may be computed, means of obtaining revenue to support the distribution process often vary considerably. Moreover, those means of support are not fixed; one delivery system may depend on a combination of resources, whereas another system of the same type may be financed by a single method. Finally, the report notes that though the technology described exists, much of it has not gone beyond the demonstration stage. As a result, the most practical cash flow procedures have yet to be determined. (DC)
