Designed to be a source of information for educators about interactive videodiscs, this handbook presents an overview of the technology and offers additional sources to be consulted for more detailed information. It is noted that, although this second edition of a 1985 publication has gone through extensive changes, clarifications, and corrections, the focus has been kept on the use of technology in education with specific information on appropriate hardware and software to provide a single-source reference for educators and trainers. Information on interactive videodiscs is presented in 10 chapters: (1) Introduction to Videodiscs; (2) Overview of Laserdisc Systems; (3) Selecting a Laser Videodisc Player; (4) Video Playback Units; (5) Videodisc Interface Units; (6) Disc Player Peripherals; (7) Videodisc System Packages; (8) Educational Videodisc Software; (9) Interactive Videodisc Authoring Tools; and (10) Care and Maintenance. Ten appendices provide directories of laserdisc players, television monitors and projectors, laserdisc interfaces, laserdisc peripherals, laserdisc system packages, laserdisc software, videodisc mastering options, and authoring language distributors; service information; and a videodisc bibliography which lists 11 books, 17 periodicals, 6 conference proceedings, 3 special videodisc publications, a directory of 14 organizations that hold conferences and workshops, and an index of 132 manufacturers.
