Authoring Techniques for Interactive Videodisc Systems

A major factor in the useability and cost-effectiveness of interactive videodisc systems is the facilities for development and revision of materials which will be used for disc mastering. Two major types of facilities are discussed and compared. A film-based premastery system has the advantage of lower initial system costs. However, a video-based system has advantages of quality, time and recurring cost savings. Projections about the future evolutions of video technology are also made as related to potential for development systems.
