A Systematic and Flexible Architecture for IP-Based Media Services: Broadcast Technical Research Institute, KBS (Korean Broadcasting System), Republic of Korea

Recently, the Internet is regarded as an important medium for media services owing to its popularity and profitability. Major broadcasting companies have been developing and refining their websites to deliver their programs individually. To satisfy user's continuous and rapid requests for novel services, broadcasting companies should renovate their systems with service-ready architecture. In this paper, we describe a systematic and flexible architecture which collects contents (e.g. essence and metadata) automatically from production systems and serves the contents to various services properly. Employing standardized metadata and a program ID in exchanging contents between systems, the proposed architecture could collect contents systematically. KBS standard of metadata and a program ID have been achieved after two years of work. For a flexible supplying of contents to various services, we utilize open API. Open API which we define can be easily applied to websites, since it is designed over HTTP. Furthermore, users can generate novel services by mashing several service concepts using our open API. We developed a prototype system, called OASIS (Open Architecture for Systematic IP-based Service) system, realizing the proposed architecture. The system collects contents from KBS programming and playout systems and supplies them to our prototype web-based contents browser implemented with our open API. Since the open API is easily applicable to web-based applications, it could be applied to mobile devices and Internet-connected TVs. Also, the prototype browser can easily expand its service functions by adding functions of the open API. The OASIS system shows the usefulness of the proposed architecture.
