Abstract
As a method of quickly displaying a thumbnail for navigation display of an AV stream, it is necessary to associate the AV stream with a thumbnail file when recording the thumbnail file separately from the AV stream file. The association, therefore, is performed by use of a serial number of the recorded AV stream file as a name of the related thumbnail file.
