Abstract: A broadcasting system for an interactive data service and a service method thereof are provided to enable a user to receive a service linked with broadcast contents by receiving a data service through a broadcast network. A decoder(50) receives and decodes broadcasting contents including user interaction contents. When the user interaction corresponding to the user interaction contents is generated, a node manager extracts return channel information for transmitting the user interaction result. According to the return channel information, a communication network connection unit(70) transmits the user interaction result. The return channel information comprises the address of a return channel server.
