Disclosed is a content management server that enables a playback restart from a suitable playback interruption position to be made possible even when editing processing has been executed on content copied to a content playback apparatus. In a content management server (200) that manages content and also performs content editing by deleting a portion within the content or adding to a portion within the content, a transmission/reception section (202) receives a first playback interruption position that is a position at which content playback was interrupted by a content playback apparatus (100), a playback interruption position calculation section (209) calculates a second playback interruption position corresponding to a position at which content playback was interrupted by the content playback apparatus (100) in content after editing, based on an editing interval deleted by editing within the content and the first playback interruption position, and the transmission/reception section (202) transmits the second playback interruption position to the content playback apparatus (100).
