LASERVISION—VIDEO DISC SYSTEM
Laservision is without doubt, the most sophisticated video disc system. Its future lies in the industrial/educational market and not the mass consumer market. The disc itself is the same size as an audio LP but is silver covered and reflective like a mirror.
Stereo sound is available when the player is linked to a hi-fi and Laservision, Fig. 36.2, offers a full range of special features including slow motion, freeze frame and picture search.
The Philips discs also offer numerous interactive possibilities once they have been specially pre-programmed. For example, they could be used to test students by posing questions and then providing the correct answers.
