Patent ID: 8924397

Claim:
An information processing device comprising: controller circuitry includes file-information acquiring means for acquiring file information that is information regarding a file to be subjected to conversion processing for converting a clip format; and conversion-management-information generating means for generating conversion management information as a database that (a) indicates a history of the clip format conversion processing on each clip including conversion hierarchy and (b) indicates an identity of each clip created by the conversion processing performed on the clip format of each clip to which the file corresponding to the information belongs, by using the file information acquired by the file-information acquiring means, wherein presence/absence of a file can be determined from the database, and re-creation of a deleted file can be determined based upon the conversion hierarchy and clip identity, wherein the conversion-management-information generating means comprises: clip-identification-information generating means for generating clip identification information; family-tree-identification-information generating means for generating family-tree identification information; clip-information generating means for generating clip information by using the file information acquired by the file-information acquiring means, the clip identification information generated by the clip-identification-information generating means, and the family-tree identification information generated by the family-tree-identification-information generating means; and family-tree-information generating means for generating family-tree information by using the clip identification information generated by the clip-identification-information generating means and the family-tree identification information generated by the family-tree-identification-information generating means.
