A content management section rearranges contents in an order from a content having a greater information value, preparing a content list. With respect to assignable areas of a display apparatus, a region value is compared with an information value of each content; the content may be assigned to the area when the information value exceeds the region value. The contents are associated with information values and the areas are associated with region values; thus, the content can be assigned to the area that is more suitable. When there are several assignable areas, a target content is assigned to an area having a highest region value.
