Method and device for inputting data in multimedia service database on embedded device

A device for inputting data in a multimedia service database on an embedded device comprising:

• a scanning module configured to, when multimedia file scanning is performed, store generated directory information of a multimedia file in a random access memory database (RAM-DB);
• a backup module configured to, in a scanning process, perform a RAM-DB to backup database (BAK-DB) data backup operation;
• and
• an interruption processing module configured to copy data in the BAK-DB to the RAM-DB based at least in part upon an occurrence of an interruption in the scanning process and continue to scan, according to existing data in the RAM-DB, a multimedia file that is not scanned,
• wherein the scanning module is further configured to:
• detect whether directory information of the multimedia file exists in the BAK-DB when scanning the multimedia file;
• copy the directory information of the multimedia file in the BAK-DB to the RAM-DB when the directory information of the multimedia file is detected in the BAK-DB;
• scan the multimedia file and write generated directory information of the multimedia file into the RAM-DB when the directory information of the multimedia file is not detected in the BAK-DB;
• detect whether directory information of the multimedia file exists in the RAM-DB when scanning the multimedia file;
• skip a scanning operation performed on the multimedia file when the directory information of the multimedia file is detected in the RAM-DB;
• and
• scan the multimedia file and write generated directory information of the multimedia file into the RAM-DB when the directory information of the multimedia file is not detected in the RAM-DB.
