Abstract: Method, system and apparatus correlate an audio message of an auxiliary sound source with an audio message from a sound track of motion picture film, video tape or other picture source with accompanying audio message track. This auxiliary source contains multiple language channels (also called "translation tracks" or "translation sound channels") running synchronously with each other. One such channel is a "prime language channel" including an audio message carrying the same information (possibly higher quality) in the same language as the message in the track accompanying the motion picture. This prime channel is derived from the same "master recording" (or high quality duplicate thereof) as the track accompanying the motion picture. Consequently the audio message conveyed by the prime channel (at high quality) is the same audio message conveyed by the motion picture track, but signals carrying those two messages may be quite different from each other: digital signal versus analog signal.

Abstract: A method and system for synchronizing a digital signal of an audio message at higher quality with another signal of the same audio message at lower quality. The invention synchronizes an auxiliary high quality audio digital sound signal source with the ordinary quality analog sound signal coming from a conventional analog sound track on motion picture film as the motion picture is being shown and maintains effective synchronization in spite of missing segments of the sound track due to film splices. The invention does not require synchronization tracks, markers, codes, time codes or other extrinsic data. The only requirement is that the higher qualtiy audio message recording, e.g. in a digital medium, be made from the same "master recording" (or a high quality duplicate thereof) as the sound track so that the auxiliary recording have the same informational content as the sound track.

Abstract: A display system, of the type used by exhibitors to attract attention or to create a desired background, is characterized by new and striking visual effects. The system receives projected images upon a mobile formed of a plurality of suspended panels free to move relative to one another in air currents. The panels, when aligned, form a surface, e.g., a rectangle having a format matching the image. Images are projected onto the moving panels of the mobile with a slide projector, film projector, or other image projection means. The projected image is separated into components by the moving panels and periodically the components coalesce partly or wholly when adjacent panels move into alignment. Changes in focus and distortions of linearity occur as panels rotate in relation to the projector's field of image. Striking and dramatic visual effects result. A still photograph may be converted into a moving, dynamic image, with devices that are durable and require little attention in use.
