Data Broadcasting is an emerging technology, which provides diverse services by exploiting underlying digital transmission technology. As the data broadcasting service is the essential part of the digital broadcasting, various middleware standards for data broadcasting have been established. However, multiple incompatible middleware result in unnecessary cost. In order to cope with these problems, this paper proposes an integrated data broadcasting middleware architecture based on the component-based approach. Through the precise comparison and analysis of middleware standards, we identify and integrate the core component of data broadcasting middleware. We expect that the preceding problems can be solved by proposed architecture.
