Interactive laser disc system

摘要

An interactive laser disc system includes a conventional laser disc player having a laser disc supporting a plurality of data segments each having instruction data and event data. The instruction data is repeated in triplicate and is processed by a comparator to determine instruction data reliability using a matching two out of three criteria. A controller operates the laser disc player to present an option screen to the user while storing the event data needed to respond immediately to the user's selection. The use of the memory and controller avoids the need of using a central processing unit and reading of the entire laser disc.
