Document Type and Number:
Japanese Patent JP4469125
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor memory card which whose storage efficiency can be improved by deleting a still picture object associatively with the deletion of an audio object. SOLUTION: A 'POB- RCN' in management information of the still picture object (POB) shows whether a display of the POB is specified with DPLGI, PLGI, or TKGI and when it is specified, its specified frequency is described. When TKI's specifying the POB are deleted, the field is decreased by the number of the TKI's. Further, even when Default- Playlist information and PlayList information are deleted, the field 7 is decreased by the number of the deleted TKI's. When POB- reference- count reaches 0, the POB file is deleted to decrease the number of POB's stored on a flash memory card.
