摘要： A time-varying image editing device is provided on a recording medium (101) and used for editing time-varying image data reproduced from a time-varying image file containing time-varying image data body (111) the items of which are arranged together with time management information in temporal order and outputted. The device includes a file-to-be-reproduced extracting section (12) for extracting a desired reproduction part of a time-varying image file. The desired part contains a predetermined reproduction time. The device further includes a file creating section (17) for storing edit information (112) for managing the extracted reproduction part and the reproduction time in an area other than the one where the time-varying image data body is stored on the recording medium (101).

摘要： A reproduction film is made capable of obtaining stable reproduction characteristics constantly. A master negative film is used to transfer data onto a reproduction film upon exposing the master negative film on which the data is recorded at the prescribed gray value, when multiple exposed areas and unexposed areas having the predetermined shape are arranged alternatively, and at the same time, the readout pattern having a guard band between the exposed area and unexposed area on the master negative film to control readout timing of the data transferred to the reproduction film, the width of the guard band is controlled corresponding to the gray value. Thereby, the signal level to be obtained from the reproduction film is to keep the fixed relative value with respect to the signal level to be obtained from the data part transferred to the reproduction film.

摘要： More than two surround sound channels are provided within the format of a digital soundtrack system designed to provide only two surround sound channels by matrix encoding from three to five additional surround sound channels into two “discrete” surround sound channels. The digital audio stream of the digital soundtrack system designed to provide only two surround sound channels remains unaltered, thus providing compatibility with existing playback equipment. The format of the media carrying the digital soundtracks also is unaltered. The “discreteness” of the digital soundtrack system is not audibly diminished by employing matrix technology to surround sound channels, particularly if active matrix decoding is employed.

摘要： The system eliminates the noise, rumble and hiss from any standard 35 mm analog optical sound track. By simply feeding the film through the projector sound head in a normal manner the system automatically converts the analog optical sound tracks to digital quality. No special storing of digital data on film is required and no special digital decoder equipment is needed. The system produces noise-free sound, increased frequency response, expanded dynamic range and clarity of the dialogue. Film studios will no longer need to carry a double inventory of films having digital and analog sound tracks or to process the sound tracks for noise reduction.
