摘要

In the technical field of management and retrieval of audiovisual assets (102), for linking audiovisual assets (102) and metadata assets (105, 106) in a way that is tolerant against postproduction modifications of the audiovisual assets (102) and does not rely upon location information of the assets (102, 105, 106), it is proposed to store, in a fingerprint pair table (108) fingerprint pairs each consisting of a perceptual fingerprint (109) of one audiovisual asset (102) and a digital fingerprint (110) of one metadata asset (105) associated to the audiovisual asset (102).
