An offset time determination unit (4001) determines a rewind offset time, which is an offset time for rewind. A content data acquisition unit (4000) analyzes a display schedule of content data in a signage terminal device that displays the content data, specifies, as rewind display content data, the content data displayed on the signage terminal device from a rewind time, which is the time that goes back from a current time by the rewind offset time, till the current time, and receives the rewind display content data from a Web server device that distributes the content data. A display unit (409) displays the rewind display content data received by the content data acquisition unit (4000). |
