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 storage method of movie digital programs. The system used in the method of this embodiment includes: a picture file compression subsystem, an audio acquisition subsystem, a sound and picture synchronization subsystem, a low bit rate transcoding subsystem, a cataloging subsystem, a media asset database, and a multi-language acquisition subsystem , Subtitle production subsystem, such as figure 1 As shown, the flow of the method is as figure 2 Shown.

[0041] The system described in this embodiment adopts a dual-net structure and pre-editing with SD materials.

[0042] Dual-network structure: The dual-network structure makes the exchange of audiovisual data and the exchange of information data use different links. It avoids wasting investment or link blockage, and ensures the smooth flow of various data.

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

Embodiment 2

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

[0124] Adding the steps of multilingual sound collection: used for the audio collection subsystem to collect each new language sound into a multi-channel sound file. A movie is often translated into multiple languages ​​for audiences of different native languages ​​to enjoy. Therefore, a movie has multiple language versions, collects different language versions, and produces them as sound files in different languages ​​for storage.

[0125] Multilingual audio and picture synchronization steps: used to use the low bit rate video of the master in the library as a reference, find the time code cheap amount of the new language sound in the audio and picture synchronization system, adjust the cheap amount, make the picture mouth shape and The sound is matched, and the synchronization relationship between the new ...

Embodiment 3

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

[0130] Steps of making dialogue subtitles: used to use the low-bit-rate video and audio of the master in the library as a reference. In the subtitle production system, the video and audio are played back, and the dialogue subtitles are made sentence by sentence according to the picture and sound, forming a time code information Subtitle files.

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

[0132] The subtitle content will be obtained from the studio, and through format conversion, it will become a high-definition standard subtitle file that can be recognized by the non-linear device. The subtitle file will be saved in Unicode format for 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 invention relates to a method for storing and extracting movie digital programs. It is a method for computer data storage. It is a method for changing a movie program recorded on a movie film or a tape to a multilingual, multi-channel and convenient format. Storage and retrieval methods. Background technique [0002] Film shooting is mainly used in the early stage of film shooting, or digital shooting has gradually emerged in recent years. The recorded sounds and pictures are stored separately, the pictures are recorded on film, and the sounds are recorded on tapes. During the post-editing process of the film, voices and subtitles in different languages ​​will be produced. The film screen and multilingual voices and subtitles will be combined to form multiple masters of the film. As the basis for subsequent film production, distribution, and value mining, the film master must be adopted Store as high as possible. [0003] The existing method is to use ...
