Cable Television Closed Circuit Television Data Processing Digital Computers Educational Television Extension Education Facilities Higher Education Library Services Medical Services Programing (Broadcast) State of the Art Reviews Student Personnel Services This survey of the potential applications of cable television (CATV) at the University of Illinois presents brief overviws of 14 possible kinds of services which might be derived from a CATV system. The purpose of the document is to encourage the development of basic planning for a cable system and to provide information useful to the university's administrative policy-makers. Services which seem sufficiently feasible to receive serious consideration include: 1) the distribution of program material from closed circuit television centers to a wider audience; 2) interconnection with the university's PLATO computer-assisted instructional system; 3) data transmission from the digital computer laboratory; 4) administrative data processing; 5) program pickup and broadcasting; 6) teaching functions in the Department of Radio-TV; 7) news and other programs in foreign languages; 8) extension services for off-campus students; 9) physical plant services monitoring; 10) building and equipment security; 11) medical services; 12) interconnections between the Law School and courtrooms; 13) library services; and 14) general student services.
