In this paper, we present the architecture of the interactive terrestrial digital multimedia broadcasting (T-DMB) system using the code division multiple access (CDMA) network for the new interactive broadcasting services. We also propose the novel structure of the novel platform based on wireless Internet platform for interoperability (WIPI), which is the standard specifications for the mobile platform in Korea, to co-operate broadcasting and telecommunication. The proposed extended WIPI platform is implemented as an emulator on PC, and an integrated browser which shows multimedia broadcasting data including AV contents and interactive data returned through the telecommunication network, is developed to carry on with it. And then to verify the proposed platform and the interactive mobile broadcasting services, we implemented the integrated receiver as well as the data broadcasting server and the return channel server. Users can get interactive services or more information about broadcasting contents through CDMA network by using the proposed platform. This shows a possibility of new interactive services in digital broadcasting by using mobility of T-DMB and CDMA
