Abstract
A content of Copy Once cannot be copied to an external device or the like, even for the purpose of making a backup. This is inconvenient for the user. However, if copying to another device for the purpose of making a backup is permitted, the content may be copied in an unauthorized manner. The present invention provides the hard disk recorder that transmits the content to the backup device, sets an expiration time in the content stored in the hard disk recorder itself, and deletes the content stored in the hard disk recorder itself after the expiration time expires.
