The Media Asset Management Based On Softbus

With the continual development and expansion of Internet and computer data network, additional the increase of network bandwidth, stream-media technique has been applied widely. And Now, almost all operators regard the stream-media technique as the next most important operation item and spare large amount of human and financial resource on it. As one of the most important asset of a media enterprise, media asset attract more and more enterprise to manage them in a more effectual way. But as we know , it always not easy to do. Especially, finding the resource what you just want in mass of source which only in original data type well and truly and quickly maybe is the most difficult things we can do. But why must we do it? It is requested by the development of industry and enterprise. So,MAM(Media Asset Management) become the first problem must be resolved of the broadcast and TV industry. Much of differences between MAM with traditional asset management made a fully new field of media technique. In our country, there are still only tiny number of enterprise develop the MAM now, while many MultiNational Corporations are try to develop a MAM fit for china such as IBM. In fact, for different culture and history, foreign company have little probability to give us a bread-and-butter MAM system. The MAM system designed by ourselves use for reference all of the in home and foreign experience in MAM and use the standard C++ language follow the C99 standard and build in softbus( software bus ) technique in which write software into module as the chip of hardware so user can add and remove a software module when they want while can keep the communication unblocked and straightway.This give our MAM system two significant features of standardization and dynamic which every software want to be provided with now. Our SoftBus design comes from the bus in hardware,bus is a widely use technique in PC hardware system. Think it in physical way, bus just a set of signal line between more than one subsystems and modules used for giving the communication channels for them. and also, bus is the core of interface with which micro-processor can connect to external hardware module and signed with two main feature of standardization and dynamic. In software ,we also need semblable mechanism to combine our hundred of modules with our main() function also between modules themselves. And so, we write the softbus. C++ language was developed from C language, it supports the OO(Object Oriented) design while keeps the excellences such as high efficiency, simple to development and near to assemble language. C++ give programmer a excellent environment for development and make the program more modularize and with higher maintainability. But because many company can have their own C++ development tool, so almost all of they add many special feature into C++ and give all kinds of C++ development tool with different standard even not compatible with each other. To resolve this problem,C99 standard been brought forward until the end of 1999. Our MAM system follow the C99 standard and so have the import features of high performance and good compatibility. At the same time,our MAM system run on high-steady and high-performance and high-available OS(Operate system) UNIX operate system so it has many strongpoint that the system based on Windows operate system has not. In database ,our system use the most popular large RDBMS (relative Database management system) Oracle 9i . Oracle support almost all of the DB standard of computer industry and distributed database and distributed process system and can easy to be porting to many other DBMS.And oracle cluster can add the more security and data stability. Based on above-mentioned design ,our MAM system own all of the excellence and run on UNIX but not Windows and total system run stably while with high performance. The idea of softbus give the system modularization design and union the HTML client with the C++ server program into a hug...
