Needs analysis Guangxi TV station decided to build a media asset management (MAM) system, mainly based on several considerations:

(1) rescue valuable historical data. Taiwan has many historical self is the use of analog tape data storage, as storage for too long, poor storage environment and other reasons, now on the verge of destruction, must be rescued as soon as possible.

(2) as Digital TV The development of television as a resource, its potential value more and more attention, and shows the accumulation of resources it takes time to be ready early, early implementation.

(3) meet the low-cost television production and broadcast needs. At present, the preservation of the various programs cost a lot of tape, the tape using digital stream can significantly reduce storage costs. Reduce the cost of television in another way broadcast system integration (program no tape operation), which achieved through MAM system. MAM system and the hard disk automatically Broadcast system Connection, you can also remove many programs to upload, not only reduces the labor intensity, but also improves air safety.

(4) need to show the current stock finishing tape, computer-based management.

Design ideas MAM system scalability, big or small, a full, complete MAM system costly, the average one-time province of Taiwan unbearable Investment . In addition, because MAM system is relatively complex task involving multiple subsystems, their construction is difficult in one step. For both these reasons, construction of Guangxi-Taiwan in the MAM system on the set of "entirety, step by step" approach, the overall plan to do large, to complete the implementation process is carried out in phases. First step to meet the needs of program memory, complete history of the rescue of valuable information, and other tape programs dump dump, later the connection between the implementation of systems and other applications (such as Video on Demand Etc.), and finally into a MAM system as the core, and for collecting, manufacturing, broadcasting, control, integration of television programs stored in the system.

According to the actual situation of Guangxi-Taiwan, we follow the "three-step" strategy for MAM system. The first step to establish a management system based on traditional tape, tape to achieve non-digital resources management programs, including tape information management, circulation management, inventory and so on. Thus, not only guarantee in the digital media before to tape the program for the unified management of resources, but also the parallel implementation of digital programs and program of cataloging, improving the overall efficiency of the system. The second step, the establishment of digital devices including (acquisition, playback), and storage systems, including, in order to save program information based on the MAM system first, save Taiwan's rare video and audio data, for all of Taiwan's all-digital platform for building foundation . The third step is to increase including a cataloging center module and transcoding, including interface components, and NLE Network and broadcast network systems seamless, completely solve the Taiwan store and share digital calls, establish a digital storage platform based on a complete MAM system.
