  • Patent number: 5065345
    Abstract: An Interactive Audiovisual Control Mechanism (IACM) which, by exploiting recent advances in CD technology which permit rapid random access of discrete audio information (such as an individual sound or utterance), provides for the first time an interactive computer system in which large amounts of high quality audio and video are presented to the user simultaneously. In the preferred embodiment, this is accomplished via random access to both CD/ROM and VD devices, wherein individual visual frames of the VD are displayed on the system's display monitor for specified periods of time while discrete sounds and utterances from the CD/ROM are played through the system's speaker. Audio from the VD and computer's CPU may also be accessed at the same time, as well as computer graphic still images and animation (due to a well-known "GENLOCK" device).
