Abstract
We propose a new up-to-the-minute data broadcasting service that uses the latest digital technologies. We produced prototype and carried out experiments to evaluate the performance of the system. The proposed service—the object-linked broadcasting service—provides various information regarding an object chosen by a viewer from a TV picture. We encountered some technical issues, such as observing broadcasting regulations, making dynamic descriptions for the objects, and working with one way transmission, in perfecting the system. To resolve these issues, we employed BML for browsing, ECMA Script for the dynamic description, Binary Table for the data structure, and DSM-CC for the transmission method. The experimental results show the system performance is acceptable. We found that an 80-second data carousel can carry related data for up to 20 objects.
