Since T-DMB commercial services have been launched, various broadcasting services such as DMB2.0, which provides interactive data broadcasting services, have emerged. Due to activation of T-DMB services, the needs of the existing video contents as well as new data contents are increasing. Especially, video contents are frequently reused because of the production cost of digitalized contents. In order to solve the problem occurring in the contents reusing process, this paper proposes the method controlling transfer rate by defining a numerical formula and verifies it through simulation.
