A main device (1) receives program data provided through broadcasting, stores the program data therein, and transfers the stored program data to a portable device (2). A set of program data is composed of program components (video, audio, subtitle, etc.). The main device (1) sets the transfer priorities of the components, distributes the program components according to the transfer priorities in the time-axis direction, and transfer them. Thus, the possibility that at least one of the program components can be completely transferred to the portable device (2) is increased even if the data transfer is canceled in a short time. Therefore, the user can view the program to the end by reproducing the program component the transfer of which has been already completed. |
