VIDEO INFORMATION RECORDING APPARATUS AND VIDEO INFORMATION REPRODUCTION APPARATUS

摘要

The present invention allows security information to be managed properly. A thumbnail encoder 19 extracts a thumbnail picture from video information input from a terminal 12 and encodes the thumbnail picture. If content management information of the video information input from the terminal 12, which is a source of the thumbnail picture, indicates 'copy once' protection, a controller 21 controls an encryption unit 22 to encrypt the thumbnail picture information before the thumbnail picture information is recorded on a recording medium 26. At that time, information indicating that the encrypted thumbnail picture has been recorded is also stored onto the recording medium 26 as a file separated from a file for storing the thumbnail picture. The present invention can thus be applied to a recording or reproduction apparatus to make the apparatus capable of properly managing security information of an AV signal.
