Problems solved by technology

[0004] Because of the characteristics of multilingual and multi-version of film programs, the existing videotape storage method requires a large amount of videotapes and high cost
resulting in having to discard part of the master's storage and instead recreate it for future use
At the same time, video tapes can only store HD format videos, and cannot support new video formats such as 2K, 4K, 3D, etc.

Embodiment 1

[0040] This embodiment is a method for storing movie digital programs. The system used in the method described in this embodiment includes: a picture file compression subsystem, an audio collection subsystem, a sound and picture synchronization subsystem, a low bit rate transcoding subsystem, a cataloging subsystem, a media database, and a multilingual collection subsystem , subtitle production subsystem, such as figure 1 As shown, the process flow of the method is as follows figure 2 shown.

[0041] The system described in this embodiment adopts a dual-network structure and pre-edits materials in standard definition.

[0042] Dual-network structure: The dual-network structure enables video and audio data exchange and information data exchange to use different links. Avoid wasting investment or link blocking, and ensure that all kinds of data are unimpeded.

[0043] Pre-editing with SD material: SD equipment is much cheaper than HD equipment, saving investment; SD materia...

Embodiment 2

[0123] This embodiment is an improvement and refinement of the first embodiment. The storage method described in this embodiment also includes:

[0124] The step of adding multilingual sound collection: it is used for the audio collection subsystem to collect each added language sound as a multi-channel sound file. A movie is often translated into multiple languages ​​for audiences with different mother tongues to enjoy. Therefore, a movie has multiple language versions, and different language versions are collected and stored as sound files in different languages.

[0125] Steps for multilingual audio-video synchronization: use the low-bit rate video of the master version in the library as a reference, find the time code value of the new language sound in the audio-video synchronization system, and adjust the value so that the mouth shape of the picture is consistent with the The sound is matched, and the synchronization relationship between the new language sound and the pi...

Embodiment 3

[0129] This embodiment is an improvement and refinement of the above embodiments. The storage method described in this embodiment also includes:

[0130] The steps of making dialogue subtitles: it is used to use the low bit rate video and audio of the master in the library as a reference, in the subtitle production system, play back the video and audio, and make dialogue subtitles sentence by sentence according to the picture and sound, forming a time code information subtitle file.

[0131] In order to save storage capacity and meet the needs of DVB, the movie digital program platform and application management system will store the subtitles of the movie.

[0132] The subtitle content will be obtained from the studio, and through format conversion, it will become a high-definition standard dialogue subtitle file that can be recognized by non-linear equipment. The subtitle file will be saved in Unicode format to facilitate font modification and replacement.

[0133] Movie s...

Abstract

The invention relates to a storage and extraction method of a film digital program. The method comprises the following steps: acquiring picture files, compressing the picture files, acquiring sound files, synchronizing the sound and the pictures, turning to a low code rate, making a catalogue, uploading and publishing, retrieving, browsing film content, submitting a download request, transcoding and synthesizing, and outputting. The storage spaces of multiple versions of the film are reduced in the premise of guaranteeing the sound and picture quality of the film to the greatest extent by adding multiple languages through picture compression and browsing, the storage and manufacture processes of the film are optimized, and the efficiency of the film in application is improved; since the languages and the pictures are separably stored, the dialogue and subtitles of multiple languages are allowed to produce to form multiple versions of the pictures, the subtitles and the languages, thereby adapting to the demands of multiusers.

Description

technical field [0001] The present invention relates to a method for storing and extracting movie digital programs, which is a method for computer data storage, and is a method for changing movie programs recorded on movie film or magnetic tape into a multi-language and multi-channel format for convenient use. Methods of storage and retrieval. Background technique [0002] The pre-shooting of movies is mainly done on film, or digital shooting that has gradually emerged in recent years. The sound and picture recorded by shooting are stored separately, the picture is recorded on the film, and the sound is recorded on the tape. In the post-editing process of the film, voices and subtitles in different languages ​​will be produced, and the combination of the movie screen and multilingual voice and subtitles will form a variety of masters of the film. As the basis for subsequent film production, distribution, and value mining, the film master needs to use Store at the highest p...
