Development of a System for Microcomputer Control of Videotape Re-corders

Abstract

This system is designed to permit students indi-vidual access to videotaped learning materials. Having this system available makes it easier for the teacher to evaluate student performance. The system consists of a master computer and two slave microprocessors. The slaves can control the videotape recorder, read and store learning material identification codes, and monitor and store information on videotape recorder utilization and tape counter data. When a student terminates use, the slave unit transfers these data to the master computer for storage on a floppy disk. Later on, the teacher can review and analyze this data using another micro-computer system. This makes it easy for him to determine which video- taped teaching materials should be kept and which can be erased and the tape reused. This system is currently in operation at the Hakodate Technical College library.
