Included are detailed discussions of thehistorical development and current infrastructure, both in termsof organization and physical plant, of the following se-vices: educational radio broadcasting, educational television broadcasting,Instructional Television Fixed Services (ITFS), Information Retrieval(Dial Access) Television (IRTV), Closed-Circuit Television, ResponsiveTelevision and Cable Television. All of the information disseminationand broadcast services described herein can currently be characterized asproviding one-way transfer of information on a point-to-multipoint basiswith the population of the receiving terminals being independent of thetransmitter or origination point within the coverage area. In the United States, a variety ofelectronic educational information dissemination and broadcast services havedeveloped, reflecting the local character of U.5.. education and a lack of resourcesand organization vis-a-vis commercial broadcasting. A series of maps have been plotted which indicate that these services, whichinclude both intra- and inter- state television networks, are notdistributed uniformly over theentire Mountain States and to U. S. Certain areas--such as Alaska, the Rocky some extent Appalachia--generallycharacterized as remote or rural areas, tend to have a dearth of services. Public television and radio, representing onesegment of electronic educational information,dissemination and broadcastservices, have in recent years developed anationalorganizational and networking base as well as goals for nationwide coverage. The creation of the Corporation for Public Broadcasting, the PublicBroadcasting Service and National Public Radio have made it possible to developthis capability. These organizations have set forth their requirements in responseto the recent filing of proposals with the Federal CommunicationsCommission by eight organizations for owning and operating U. S. domesticsatellite systems. After reviewing these requirements, and afterconsidering key issues such as regional versus national versusspecial programming, we have set forth potential long-haul telecommunicationsrequirements for public television and radio distribution. An Appendix to this memorandum summarizes the key features of the eight U. S.domestic satellite proposals and comments on the suitability ofthese proposals for meeting tne requirements of public broadcasting. 3 CONTENTS Page No. 1 1. Introduction 2.

An essential foundation for possible, phase of the work is ananalysis , in as quantitative terms as educatioral/instructional services which are pos- of the wide variety of sible using telecommunicatons and adetermination of future requirements for such services. For the purposes of systemssynthesis, one has to havedetailed information, to the cxtentfullest possible, regarding thetelecommuni- dedicated type cations infrastructure thatalready exists--especially the designed to provide exclusiveeducational
