Currently the multimedia contents and various terminal devices owned by public agencies or private companies are operated separately by their manufacturer. This can make an immediate action impossible in the event of failure in equipment or contents due to the lack of integrated management, and it can also cause a lot of administrative costs for the maintenance of equipment for each type. In addition, the ineffective management of contents brings about such problems as errors, duplication and inconsistency in the contents. To solve these, construction of an integrated management system as well as an efficient, low-cost operational system is required. The system proposed in this paper integrates and controls the remote terminal devices, and it implemented in a multicast way. For each of many different devices in remote locations such as set-top boxes, kiosks and speakers, functions including broadcast schedule edition, multimedia playback automation and subtitle display configuration are controlled directly at the central system. The system has been developed mainly on the algorithm of Middleware for multicasting large amounts of data and centralized group management. As a result of the test in conjunction with the actual devices, this proposed program could easily integrate the heterogeneous terminals.
