Abstract: A user terminal program (1, 10) enables a user terminal apparatus for accepting instruction information specifying a content that a user wants to reproduce on a predetermined reproducing apparatus other than the user terminal apparatus (STEP 1), acquiring system identifying information to identify a system to receive the specified content from a distributing site (STEP 2), judging whether the acquired system identifying information is included in a compatibility file which includes one or more system identifying information (STEP 4) 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 (STEP 10), and writing the received content to an internal memory or an insertable memory of the predetermined reproducing apparatus (STEP 13-15).
