Abstract
A transmitting unit has a first storing portion for storing a plurality of data programs, and a data generating portion for adding first identification data to a data program selected corresponding to selection data that is input by a user from the plurality of data programs stored in the first storing portion. A terminal unit has an operating portion for inputting selection data for selecting users's desired data from the plurality of data programs stored in the first storing portion, a second storing portion for storing data to which the first identification data transmitted from the transmitting unit is added and for storing second identification data that is unique to the terminal unit, a reproducing portion for reproducing data that is read from the second storing portion, and a controlling portion for comparing the first identification data added to the data that is read from the second storing portion with the second identification data that is stored in the second storing portion and controlling a reproducing operation of the reproducing portion corresponding to the compared results when the data that is read from the second storing portion is reproduced. Thus, data can be protected and its ownership can be transferred.
