In this paper, we present the configuration diagram of the interactive terrestrial digital multimedia broadcasting (T-DMB) system using the code division multiple access (CDMA) telecommunication network for the interactive broadcasting services. The system consists of a T-DMB transmission system, a interactive receiver with a CDMA module, and a return channel server. We also describe the protocol stack for providing data broadcasting service in T-DMB and the interactive broadcasting web site (BWS) service of a new concept based on it. In order to verify the proposed service, we design and implement an interactive T-DMB receiver with a CDMA module. And also a return channel server is operated to test it, which includes the interactive contents produced in advance, responding user's request. Under the constructed test environment, the proposed service and the newly designed receiver were verified. This means that new interactive services in digital broadcasting are possible by using mobility of T-DMB and CDMA.
