To verify the operation of content of data broadcast easily.

A data broadcast scheduler 51 copies data for data broadcast from a C: ¥TEMP directory 81 to a C: ¥Broadcast directory 62 according to a predetermined schedule, and outputs a command related to reading the data for data broadcast to a data broadcast simulator 53. Depending on the command from the data broadcast scheduler 51, the data broadcast simulator 53 reads out the data for data broadcast from the C: ¥Broadcast directory 62. A BML browser 55 executes processing corresponding to the data for data broadcast read out by the data broadcast simulator 53. The invention is applicable to a simulator for verifying the operation of data broadcast.
