DATA PROCESSING APPARATUS

摘要

When a portable terminal apparatus 11 which is a data processing apparatus acquires right data 92 in addition to stored contents data 91, for example, to reacquire previously acquired right data, the portable terminal apparatus 11 accesses a distribution source server 12 based on distribution source information 93 and acquires right data corresponding to the contents data 91. Then, the portable terminal apparatus 11 converts the acquired right data so as to be adaptable to a second DRM system in a memory card 13, outputs the converted right data to the memory card 13 and updates the right data 92.
