ABSTRACT:
A user terminal program enables a user terminal apparatus to accept instruction information specifying a content that a user wants to reproduce on a predetermined reproducing apparatus other than the user terminal apparatus, and enables acquiring system identifying information to identify a system to receive the specified content from a distributing site. Moreover, the terminal program enables judging whether the acquired system identifying information is included in a compatibility file which includes one or more system identifying information for receiving the specified content according to the system identifying information if the acquired system identifying information is judged to be included, and prohibiting receiving if judged not to be included. Furthermore, the terminal program enables writing the received content to an internal memory or an insertable memory of the predetermined reproducing apparatus.
