A Flexible and Practical Content Exchange Framework at the Korean Broadcasting System
2007
There is a growing need for exchanging content among heterogeneous content management systems without altering their management structure (e.g., database schema, original file format). To guarantee the original structure of each system, an exchange method should be flexible in order to be applicable to various environments. This paper describes a flexible content exchange framework that enables systems to exchange essence and metadata by means of both consolidated (i.e., MXF) and separate (i.e., original essence file and XML) methods. The DMS-1-based exchange metadata scheme is designed to be equally applicable to both methods, therefore systems can handle content equally, regardless of exchange methods. Furthermore, exchange protocols in this framework facilitate this two-way exchange. The exchange protocols also enable systems to exchange content via FTP or basic TCP/IP and upload or download the content according to their intentions. The proposed framework has already been standardized inside the Korean Broadcasting System as a way of exchanging content between production systems. Also, a validation tool that validates the conformity of each system to its standard has been implemented. It is expected that this flexible framework and standardization will accelerate content sharing among independent systems.
