Abstract: When a secure counter malfunction detection unit 212 deters a malfunction in a secure counter 211, a content playability judgment unit 206 performs a content playability judgment based on information managed by a malfunctioning-state playback processing management unit 214. The malfunctioning-state playback processing management unit 214 stores a malfunctioning-state playback condition composed of information such as a playback count and a playback time. The content playability judgment unit 206 judges that content is playable when the malfunctioning-state playback condition is met, and a content playback unit 210 splays the content.
