An image processing apparatus includes a reception unit configured to receive a transmission request of information on a directory for managing contents from a display apparatus, a transmission unit configured to transmit a response to the transmission request received by the reception unit, and a notification unit configured to notify the display apparatus of a change in a predetermined directory, thereby causing the display apparatus to transmit a transmission request of information on the predetermined directory again. When a new directory is formed on the same layer as that of the directory for managing the contents as a result of addition of the contents in the storage medium, the notification unit notifies the display apparatus of a change in a directory located on a layer above the directory for managing the contents.
