ABSTRACT:
To play back a content while managing the right of use of the content, such as a total time of playback of the content, an electronic device stores right information in a right temporary storage unit59and judges whether or not use of the content is permitted, in a process of decoding a frame. Also, the electronic device updates the right information stored in the right temporary storage unit59. When the frame to be played back is the one at a predetermined position in order, the electronic device stores the right information stored in the right temporary storage unit59into a storage area20.
