Abstract
The invention discloses a virtual-medium-based material storage management method and system. The method comprises the following steps that: introducing high-quality audio-video file paths and material metadata information of materials through invoking a material import interface by an external system; copying high-quality audio-video files of the materials into a high-quality storage subsystem; converting the high-quality audio-video files of the materials into audio-video stream media files, storing the audio-video stream media files in a stream media storage subsystem, and associating high-quality files into a virtual medium according to an association strategy; determining whether the virtual medium is fully filled with the high-quality files, if yes, writing contents in the virtual medium into a physical medium by a read-write device; storing the physical medium in a strip rack; and finding out a required physical medium by a user through browsing stream media so as to take back the stream media physical medium for use. According to the method, material storage, access and browsing efficiencies are improved to a large extent, the management efficiency and work efficiency of media contents are improved, and the system cost is greatly reduced. In addition, the invention discloses a system for implementing the method.
Description
Technical field
The present invention relates to the storage management technique of material, relate in particular to the storage of audio frequency and video material in a kind of media asset management field and the new method of management, and the management system that realizes this method.
Background technology
Along with the development of the continuous progress of science and technology and society, the content material of all trades and professions presents explosive growth, and how safety, storage, these huge volumes of content assets of management and use efficiently become the problem that the Content Management field presses for solution:
1, field of broadcast televisions: the development of HDTV, the real-time of content reach quarry widely, from the SD to the high definition, the size of media file is doubled and redoubled, for widely used three grades of storage organizations are bad easily owing to magnetic tape station at present, often there was a mechanical failure, visit capacity is limited simultaneously for tape pool, causes the storage of file and move back being difficult to satisfy professional demand for development, and this just requires the memory capacity of audio-video document bigger, the efficient of moving back is higher, the storage is safer.
2, new media field: distribution of contents by all kinds of means, audient are higher to the requirement of image quality, to the real-time of information issue, the storage of media file have been proposed new requirement.New media requires the relative broadcasting and TV of audio frequency and video quality field lower, but requires coded format variation more, and it is online to require more audio frequency and video material to be stored in, and can real time access.
3, safety-security area: a large amount of monitor datas and criminal investigation video evidence, along with development of technology, the monitor data quality is higher, image is more clear, the online disk of finite capacity can't be stored too many file, if can allow memory capacity bigger, retrieval, extraction more quick and precisely also become the problem that the storage administration of the sector audio-video frequency content need solve.
4, other industry: education, medical treatment, religious organizations etc. are urgent further to the demand of media content.
The storage mode that is applied in the Content Management field at present is mainly by three kinds:
1. based on the unusual difficulty of storage administration (as: DVD management system) content search of physical medium, the content in can't the fast browsing CD is loaded down with trivial details for the magnanimity CD managing.
2. based on the storage administration of disk array, it is very high to search cost, and finite capacity, disk break down easily and cause loss of data.
3. three grades of storages of online, near line, off-line, cost height, failure rate height can only be supported numerical tape, the efficient of moving back is lower, difficult management.
Also do not have the cost in a kind of suitable media contents management field low at present, security is higher, content is quick and precisely searched, extendability is strong, support the storage management system of multiple physical medium, manageability, easy care.
Summary of the invention
