Verification of WIPI-based T-DMB platform for interactive mobile multimedia services

Abstract

This paper presents the architecture of the interactive terrestrial digital multimedia broadcasting (T-DMB) system and the integrated receiver using the code division multiple access (CDMA) network. And a novel architecture of WIPI-based T-DMB platform will be proposed. The proposed extended WIPI platform is implemented as an emulator, and an integrated browser which can show multimedia data with interactive data contents at a time developed to be carried on it. 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 through CDMA network by using the proposed platform. This shows a possibility of new interactive services in the digital broadcasting by using the mobility of T-DMB and CDMA.
