It supports all types of storage frameworks (such as SAN, NAS, IP-SAN, ISIS), the tape library of Quantum, IBM, HP, SUN and other brands, all types of tape drives (such as LTO3, LTO4, LTO5) and interfaces such as SCSI, iSCSI, SAS and FC.
The multimedia application oriented HSM archiving management software, and patented technology-based tape redundancy and fault-tolerance processing mechanism are adopted as well.
Collection and upload module
The automatic archiving of contents from all production networks, collection and recording network, digital broadcast system and high security zone is supported; the automatic related archiving based on series and construction documents is supported; the full format AV signal, semiconductor medium, manual upload (e.g. file import) and many other collection and upload methods are provided; some auxiliary functions are provided as well, such as processing of assignments in storage, verification of data integrity, automatic technical review on digital content, inheritance of metadata, pre-cataloguing, sorting and sifting of materials.
Cataloguing and audit module
The primary (pre-cataloguing), secondary cataloguing as well as multi-level cataloguing, auditing will be carried out on materials in storage and finished products; supporting manual recording, automatic cataloguing, offline cataloguing and remote cataloguing. Hierarchical cataloguing is adopted, supporting all cataloguing rules and customized flexible cataloguing specifications, and the cataloguing rules are in accordance with relevant national laws and regulations.
Content management module
The content management engine supports object management, metadata management, data retrieval, copyright management, storage management; the DRM copyright management engine can carry out the labeling, registration, certification and authorization of copyright through DRM database and XML in accordance with copyright management specifications; the storage management system will complete the hierarchical storage management on structured and unstructured data objects via life cycle strategy.
Index retrieval module
The intelligent analysis, automatic cataloguing and automatic indexing on unstructured video and audio content are accomplished; through Full Text Search engine, the automatic indexing on massive document contents (such as Chinese texts, English texts, webpage, XML, DOC) is achieved, providing accurate, efficient and comprehensive query; facing millions of data, the feedback time of retrieval is within seconds; it supports displaying retrieved results as per correlativity, classification and preference strategy.
Ex-library download module
After retrieval and browsing, the user can submit the download application. The approved links will enter the download queue; ex-library will be controlled by the content management module, and program materials will be transferred to the operation segments of news, production, broadcasting, etc. at the intranet of the TV station; content support will be provided to new media operations (such as digital TV, network media, mobile phone TV, mobile TV, interactive TV, newspaper, website) via releasing the interface of trading platform, and the full format efficient transcoding is supported as well.
The whole-station media asset system of Tianjin TV has provided operation functions such as upload, collection, cataloguing, audit and management of historical materials for the Editor Office of Tianjin TV as well as all operation systems of the whole station. Meanwhile, it also provides accurate query, efficient retrieval, fast browsing and download services to users of the whole station media assets. Operation support will be provided to program topic selection, program arrangement, program broadcasting and content release through operation management subsystem. The interconnection and application integration of program production and broadcast network of Tianjin TV (for news, production and sports programs) with digital hard disk broadcasting system are achieved through the interconnection interface subsystem.
Zhejiang Radio and Television Group
In the digitization system of emergency treatment project for historical news films and televisions at Zhejiang TV, the planned and designed storage management system supports the multileveled (on-line, near-line, off-line) storage system, adopting multichannel, cluster-type storage management framework, supporting object-oriented storage methods, ensuring efficient archiving and restoration.
