Description

Media storage system and method

TECHNICAL FIELD The present invention relates to storage technologies, and in particular, to a media storage system and method. Background technique

An existing media storage system consists of multiple repositories, each of which is used to store media content for different lifecycles/business cycles. For example: In the existing broadcast television production system, the original material storage is used to store media files or media streams directly received from the media source; the program storage library is stored for storage by an external transcoding system and production system. Subsequent media files; The standby database is used to store media files that are ready to be broadcast.

However, in the existing media storage system, one media content can be stored in different storages in a different format in different life cycles/business cycles, and each storage library is independent of each other. In the existing media storage system, although the media content of different life cycles/business cycles are stored in the same shared storage library, such a shared storage library merely provides a basic underlying storage interface, and cannot directly support the above-mentioned Media services, for example: There must be other external devices to record the live video stream into media files, or other external devices must convert the media content read by one format to the media in the format to be stored. After the file is saved, the final media file can be stored in the above shared storage system; similarly, when the user needs to access the media file in the shared storage library, the user can only read the media format currently stored in the shared storage library, and cannot Media format, or media streaming mode access, unless the shared repository will be Export file storage media, and then be converted or fluidizing medium format devices by other external systems. On the other hand, the shared repository generally only provides a file system, and does not support the management of metadata, such as directors, actors, and dialogues, of video files. It must also have other external devices to provide media content. Metadata management. In the above shared storage library, media management and storage management are relatively independent, and the system of combining the two parts is complicated, flexible, and inefficient. For example: The current media asset management system. In the media asset management system, it can be generally divided into three layers: media asset business, media management and storage management, in which media asset business and media management are tightly coupled, taking the broadcasting industry as an example. Users can only purchase a complete set of media asset management systems. The system cannot provide media management and storage management services for other media services (such as production services, broadcast control services, news services, etc.).
