Program targeting is being considered as a promised application in the coming PDR-based broadcasting services. However, to reflect user preference perfectly in the program selection process when using only program metadata is difficult, and to respect the intentions of service providers and broadcasters in providing programs is also difficult. Therefore, to solve this problem, we propose a program-viewing control system, in which metadata control is linked with viewers program-viewing history in a way that is easy to implement. Moreover, this system supports more sophisticated program targeting, called program substitution. The details of the proposed program-viewing control system and the metadata used are described in this paper. A comparison of the proposed system with other existing similar systems and methods proves that the proposed method is more effective and beneficial.
