摘要 |
A content reproducing device (10) capable of changing over from a title list where purchased contents and unpurchased contents are mixedly listed directly to the content purchase procedure and reproducing an unpurchased content as a purchased content. The content reproducing device (10) comprises a storage medium (13) storing purchased viewable contents and unpurchased nonviewable contents, a content list generating portion (11) for making a list of the contents stored in the storage medium (13), and a controlling portion (14) for allowing a displaying apparatus (30) to display the content list made. The content list shows the contents irrespective of whether each of them has been purchased or not. Through the content list, the user can be directly authenticated by a content reproduction authentication server (50) to perform the purchase procedure. After the purchase procedure is ended, the unpurchased content is changed to a purchased content, and the content can be reproduced as it is.
