The Turning Point in Communications Systems
The DiscoVision System
What does the system do? Attached to standard or projection television and high fidelity sound equipment, the DiscoVision system produces pre-recorded picture and stereophonic or bilingual sound of extremely high quality. By using the microcomputer, the DiscoVision system has a unique, important capability: "interactive programming," a new term that defines programming that responds differently to different viewers. Used as an instructional system, for example, the DiscoVision system can teach, test, and review material based on individual learning rates. How does the system work? Sound and picture are pre-recorded on the videodisc using high density, industrial recording and molding techniques. There are up to 54,000 tracks on a disc, separated by 65 millionths of an inch. Each track represents one picture frame. Sound and computer instructions are also recorded on the disc. The disc can be played on both industrial and consumer players. A helium0neon laser is used to "read" the information from the disc, spun on a turntable at 1800rpm. How is the system programmed? Using a hand-held remote controller and a simple push-button technique, the DiscoVision system can be programmed manually to locate any one of 54,000 numbered frames quickly. By pre-programming instructions, any choice of still frames or motion sequences can be called up automatically. What about playback? With the DiscoVision player, video images are produced in either high quality full-color or black and white through any standard television. DiscoVision discs feature 2-channel high fidelity audio, making possible either stereophonic sound, dual language or question-answer formats when played through any standard amplifier and speaker combination. Are there any special operational feature? Not only special, but unique. The DiscoVision system offers forward and reverse slow motion, freeze-frame, frame-by-frame viewing, selectable audio, forward and reverse scanning and direct automatic random access. Are DiscoVision discs fragile to handle? Not at all. DiscoVision discs are durable: the plastic surface of the disc protects the embedded information layer from dust, fingerprints, superficial scratches and other handling hazards. The discs can be stored, handled and mailed easily and safely. What's the replay life? Because the DiscoVision system utilizes a laser beam to sense the recorded information for playback there is no physical contact on the disc. No wear occurs which could degrade the disc or the quality of the information recorded on it. The 1,000th play of a DiscoVision disc will produce just as sharp and clear a picture as the first playback. DiscoVision Player Features:
