ABSTRACT:
Even when a movie or the like is distributed in an electronic state, reproduction control can be effectively performed for each region at a distribution destination, thereby providing a reproduction control program capable of widely distributing distributed information in an effective manner.The reproduction control program acquires distribution information which is distributed along with region information indicating a reproduction permitting region, and the reproduction control program is installed to a terminal T to operate the terminal T for reproducing the acquired distribution information. The region information indicating the reproduction permitting region based on the reproduction control program is stored in the terminal T, and it is confirmed whether or not a coincidence is made between a region indicated by the stored region information and a region indicated by stream region information included in the acquired distribution information. The distribution information is reproduced only when the region indicated by the region information and the region indicated by the stream region information are coincident with each other.
