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.

Abstract: The invention relates to power saving in portable terminals ( 100 ) with recording media ( 200 ). Conventionally, there is the problem that a battery ( 104 ) in the portable terminal ( 100 ) may become exhausted and as a result the original function of the terminal cannot be performed. To solve this problem, when the remaining battery capacity is low, the invention controls power supply ( 108 ) to the recording media ( 200 ) and clock supply ( 110 ) to a CPU ( 202 ) in the recording media ( 200 ) so as to reduce power supplied to the recording media ( 200 )
