Abstract
An internal data storage unit stores distributed music data. A copyright management table stores a process right to each music data item. The process right includes a playback right and a right to copy the data to an external storage medium. A control unit refers to the stored process right to determine whether an inputted instruction can be executed. If determining that the instruction can be executed, the control unit supplies a control signal to a playback unit or another relevant process unit. A display unit displays the stored process right based on an operation mode set in a mode storage unit. The playback and copy rights to the data are displayed with icons. If an icon indicating a copyright in use is selected, information is displayed about the external medium to which the data was copied. If the inputted instruction cannot be executed, a warning screen is displayed.
