A data broadcast content generation system stores body data for displaying a body page, a plurality of sets of part data each being composed of display element data for determining a display element and attached data for displaying an attached page, and schedule information which associates each broadcast data slot with a set of part data. For each broadcast time slot, the body data, display element data of the set of part data, and attached data of the set of part data are related to each other, so that a display element determined by the display element data will be displayed in the body page and a link destination of the display element will be an attached page displayed using the attached data. The body data, the display element data, and the attached data are then set as carousel data to be transmitted during the broadcast time slot.
