- Information Retrieval by Television. Billowes, C. A. Educational Media Educational Television Equipment Utilization Information Retrieval Information Systems Instructional Films Instructional Innovation Libraries Networks Resource Centers Telephone Communications Systems Videotape Recordings Bell Canada, the Public School and Collegiate Institute Boards of Ottawa, and the Ontario Institute for Studies in Education are collaborating on an educational television project which will provide a retrieval system that can supply any given program at any time under the control of the classroom teacher. Four schools in Ottawa will participate in the initial phase. The system comprises a library of 1500-2000 videotapes and films, a signal originating center, a coaxial cable trunk distribution system to the schools, and a school building RF coaxial cable distribution system. Each receiver location consists of a television receiver, a private line telephone to the central library, and a program catalog. The teacher makes a request by lifting the telephone receiver and arranging with the librarian situated at the head end for a specific program to be broadcast at a specific time. The program is then multiplexed to the standard VHF channels 2-13. Full service is scheduled to begin January 1969. (JY)
