Abstract
Abstract An audio/videodisc synchronizer accepts random access frame numbers and records digital ques on one track of a magnetic tape. Other tape tracks are available and are used for recording audio or for synchronization of other videodiscs. When the digital ques are played back through the synchronizer, a videodisc player is controlled through its computer interface. As a result, by use of ordinarily available components, virtually unlimited audio is available per still video frame. The device of the present invention provides for remastering of the program audio independent of the videodisc source and thereby eliminates the need for video frames with audio to be recorded on the videodisc in the same sequential order in which they will be played, when continuous audio is required, and allows video frames to be removed or added into an existing presentation. Importantly, the present invention allows a user to fully utilize the large storage potential of videodiscs, currently 54,000 frames per side, for smaller presentations by allowing the audio source to select the video frames to be viewed. This means that one videodisc could hold hundreds or thousands of various video presentations and the user could have many audio tapes corresponding to a single videodisc.

Claim 2
Independent Claim
165 words
An apparatus for synchronizing audio signals and videodisc signals comprising: (a) a synchronizing means for translating computer signals containing que information into audio signals containing que information and for translating the audio signals containing que information into the computer signals containing que information; (b) a videodisc playing means, detachably connected to said synchronizing means, for playing a videodisc means containing a compilation of a plurality of discrete video images, upon receipt of said computer signals; (c) a video monitor means detachably connected to said videodisc playing means for visual display of said images from said videodisc means; (d) an audio player/recorder means detachably connected to said synchronizing means for receiving and recording said audio signals containing ques corresponding to selected images on said videodisc means from said synchronizing means for playing back said recorded audio signals containing que information to said synchronizing means; and (e) a sound system means connected to said audio player/recorder means for sound distribution of audio track signals from the player/recorder.
Claim 3
Dependent Claim
161 words
The apparatus of claim 1 wherein said synchronizing means further comprises: (a) a power supply and conditioning means for receiving electrical power; (b) a microcomputer means for storage and processing of said computer and audio signals containing que information; (c) audio output translating means for translating said audio signals containing que information into audio signals containing que information; (d) audio input translating means for translating said audio signals containing que information received from the audio player/recorder means into computer signals containing que information; (e) a play/record mode selecting means for selecting either a play mode or a record mode; (f) a trigger indicating means for indicating when a signal is being received from the audio player/recorder means; (g) a valid signal indicating means for indicating that said signal from the audio player/recorder means is valid; and (h) a que signal indicating means for indicating that a video disc que is being transmitted from the synchronizer means to the videodisc playing means.
Claim 4
Dependent Claim
40 words
The apparatus of claim 2 further comprising an interface means connected to said synchronizing means capable of storing entire que maps of videodiscs so that computer signals for selected ques are transmitted to said synchronizing means in a selected order.
Claim 5
Dependent Claim
49 words
The apparatus of claim 3 further comprising a manual que means whereby said ques stored in said microcomputer, are translated and, as desired, sent to said tape player/recorder means for recording or to said videodisc means for viewing an image corresponding to said que on said video monitor means.
