Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motion picture film and a recording apparatus therefor, and more particularly to a motion picture film in which a digital sound track for recording audio data is formed along a film running direction and a recording apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, a movie film is often distributed as a plurality of films by dividing a long movie into about 20 to 30 minutes. Then, when the film is shown, it is connected and reproduced as a single film, or alternately reproduced by a plurality of reproducing devices. Therefore, if the order of the plurality of films cannot be understood, there is a problem that the films cannot be reproduced in the correct order.

Further, in general, a motion picture film does not record information about the contents recorded on the film or the recording format of the audio track. Therefore, the contents recorded on the film are recorded on paper, labels, etc., or displayed on a film can or the like for storing the film.

Then, when reproducing a film,
When it was necessary to know the content recorded on the film and the recording format, the label on which the content was recorded or the display on the film can was observed.

[0005]

Therefore, if the label or the like on which the contents are recorded is lost or the film is put in the wrong film can, it becomes difficult to know the title and recording format. was there. For example, in a movie film having a digital sound track for recording voice as audio data, if there are films of a plurality of audio data encoding systems, recording formats, versions, etc. for one movie, these recording formats, etc. Was printed on paper, labels, etc. Therefore, if the label or the like describing the recording format is lost, there is a problem that the recording format of the audio data cannot be understood only by looking at the film.

In order to confirm the recording format of the film in which the recording format of the audio data cannot be understood in this way, a method of reproducing and confirming the film using a reproducing apparatus can be considered. For example, when confirming the recording format of a film, it is necessary to have a reproducing device compatible with all recording formats, and it is necessary to be familiar with the operation of the reproducing device and all recording formats.

Further, for example, when confirming the version of a film, it is necessary to search for a characteristic portion of a different version, and it takes time to confirm which version. Further, if the contents of the film are not well known, it is impossible to confirm which version, and there is a problem that it requires skill to confirm the version.

Further, in general, when a motion picture film is produced, the sound recorded in the sound track is edited as a sound negative film containing only sound in addition to the image,
This audio negative film was transferred, and the video and audio were synthesized to create a positive film. The soundtrack is created by, for example, cutting and pasting an audio negative film on which audio is recorded and editing the film.

For a voice negative film, the order of the films,
Information such as location is not recorded. For this reason, the order of films, the roll number, and the like may become unknown during editing. Then, once the order and the like are unclear, no video is recorded and it is difficult to confirm the order and position because there is no feature, and management is difficult.

The present invention has been made in view of the above problems, the contents recorded on a film are not unclear, the skill is not required, and a special device is not required. It is an object of the present invention to provide a motion picture film and its recording device, in which contents recorded on a film, for example, a title, a recording format, a version, etc. can be easily confirmed and which is easily edited.
