Design And Realization Of Media Assets Management

The realization of digital operation is the development trend of the TV broadcasting technology. Computer technology has been growing rapidly and has applies to the every aspect of television programs, introduced a lot of new concepts and ideas to the industry, and it has changed the traditional programming methods, as well as the transmission and broadcast programs in a great way. According to the request from SARFT, digital TV broadcasting technology will be promoted nationally in 2008, and the analog TV broadcasting will be terminated then and it will be replace by the digital TV broadcasting around China in 2015, cover by cable, satellite and wireless means.Television Stations have accumulated great number of precious video and audio data since its inception; these enormous and valuable assets need to be preserved properly. At the same time, an efficient, secure and reliable program editing and management system is the key for the consistent development and stable leading position maintenance in the increasingly fierce competition. In line with the growth of channels and the enlarging of the scale of the program, the quantity of the outcomes is increasing continuously with sound quality, therefore the construction of a media asset management system for producing programs and the storage of video and audio data is the most urgent priority.The content of this paper is to design and build a demand satisfied Media Assets Management System for realizing the digital and automatic process from capturing clips to program producing as well as the storage and transmission of the program materials. The system satisfies the current demand and fits the future development, and it can be transferred from Standard Definition to High Definition by a simple system upgrading.According to the system requirements analysis, and the design principles of effective, reliability and security, this paper mainly focuses on the equipment selection and internet capacity analysis, and defines 5 sub-systems of the whole system: program edit, embellishing, dubbing, catalog index, and verification. The development and constructed were based on Apple's Storage Area Network, with Apple's media technologies and RealBasic development tools, also it used the PostgreSQL as the database system. This paper introduces the expansive applications of some softwares such as Apple Final Cut Pro, Compressor, Motion. It also outlines the design and developing method of some of the systems, inclues C/S based Media Asset Management System, database design, business flow design and storage scheme design.
