Abstract: The present invention provides an additional effect system and method, the additional effect system including: a plurality of projection surfaces installed in a single theater; and an additional effect device for implementing an additional effect other than images projected on the plurality of projection surfaces, wherein the additional effect device provides the additional effect depending the images projected on the plurality of projection surfaces.

Abstract: A recording and reproducing device including sound collecting means for collecting external sound, and outputting sound information corresponding to a result of sound collection, photographing means for photographing an outside, and outputting image information corresponding to a result of photographing, recording means for converting the sound information to files in message units and recording the files on a predetermined recording medium, and recording the image information on the recording medium in association with a corresponding file of sound information in response to a predetermined first external operation, display means for displaying images based on image information associated with respective files of sound information, and reproducing means for reproducing a file of sound information associated with an image selected by a predetermined second external operation among the images displayed by the display means.

Abstract: In encoder side, an electronic watermark generating device generates an electronic watermark which contains a encryption key. An electronic watermark inserting device inserts the electronic watermark containing the encryption key into a first portion of data. An encrypting device encrypts a second portion of the data with the encryption key. The first portion into which the watermark containing the encryption key has been inserted and the second portion which has been encrypted with the encryption key are combined by a switch and thereafter recorded on a record medium or transmitted to a network. In decoder side, the watermark containing the encryption key is extracted from the first portion and the encryption key is extracted from the watermark. The second portion is decrypted with the extracted encryption key.

Abstract: This invention discloses an apparatus for apparatus for conducting a comparison of a plurality of versions of a movie which differ at least in their audio channels and for generating an editing list for an output movie on the basis of the comparison, the apparatus comprising a movie version synchronizer operative to compare a plurality of movie versions which differ at least in their audio channels and generating a signal representing the mutual synchronization of the plurality of movie versions and an output movie generator receiving the synchronization signal and operative to generate a signal representing an output movie editing list for an output movie.

Abstract: A digital time code is printed in an area of a motion picture film, between the normal analog optical sound track and the picture frames, that is exposed along with the sound track when a print is made. This area is partially redeveloped, and normally reserved to isolate the analog sound track from the picture frames. Digital audio for the motion picture is stored in a large capacity high integrity archival digital storage system. The time codes corresponding to known locations on the film are read as the film is played, and in an anticipatory pass the digital audio signals for these frames are transferred to a fast access data storage buffer which temporarily stores the data before it is converted to analog format for theater play. The time code is read with light that is absorbed by the film dyes produced when the film is developed.

Abstract: A photographed image reproduction apparatus for reproducing photographed images recorded on a film includes an image reproducer for reproducing an image on the film, a music player for playing a music suitable for the image, and controller for controlling the image reproducer and the music player so as to execute the image reproduction and the music play coincidentally. The controller has a calculator device for calculating an image reproduction time and a selector device for selecting a music suitable for a reproduced image among a repertoire of musics.

Abstract: A circuit for storing a control signal on a selected length of strip material such as a magnetic tape having a tape head associated therewith and provided with longitudinally spaced marking signals. The circuit includes a control signal generator arranged to be switched on by a control unit to produce a control signal which is applied to the selected length of strip material, and a first detector responsive to the marking signals for switching off the control signal generator when a marking signal is sensed in one direction of movement of the tape material together with a second detection responsive to the stored control signal for switching on the control signal generator during the movement of the tape in the other direction to store the control signal throughout the selected length of strip material, the first detector switching off the control signal generator when the other marking signal is sensed by the first detector.

Abstract: A switch adapted to cooperate with the pull-down claw of a silent movie camera for transmitting an electrical signal each time a frame of movie film is advanced past the shutter of the camera includes an insulating base adapted to be positioned within the film receiving compartment of a movie camera so as to fit around the film gate, the base having a grounding contact arm engaging the gate so as to be grounded through the camera and a contact finger insulated from the gate and disposed for intermittent engagement with the reciprocating pull-down claw which serves to close the switch each time a frame of film is advanced past the shutter.
