MULTIPLE STEP IDENTIFICATION OF RECORDINGS
First Claim
1. A method, comprising:
- accessing associated data that is associated with a recording, the associated data forming part of metadata associated with the recording;
extracting at least one fingerprint from at least one portion of the recording containing at least one of audio or video content data; and
storing the at least one fingerprint as identifying information for the recording when a match of the associated data is found in a database that contains the associated data, the associated data and the at least one fingerprint to be used in future identification of the recording.

Abstract
Multiple information is extracted from an unknown recording and information associated therewith. Associated information includes the filename, if the recording is a computer file in, e.g., MP3 format, or table of contents (TOC) data, if the recording is on a removable medium, such as a compact disc. At least one and preferably several algorithmically determined fingerprints are extracted from the recording using one or more fingerprint extraction methods. The information extracted is compared with corresponding information in a database maintained for reference recordings. Identification starts with the most accurate and efficient method available, e.g., using a hash ID, a unique ID or text. Fingerprint matching is used to confirm other matches and validation is performed by comparing the duration of the unknown and a possibly matching reference recording.

30. A system, comprising:
-
a receiving unit to obtain associated data associated with a recording, the associated data forming part of metadata associated with the recording; an extraction unit to extract at least one fingerprint from at least one of audio or video content data contained in at least one portion of the recording; and a storage unit, coupled to the receiving unit and the extraction unit, the storage unit to store the at least one fingerprint as identifying information for the recording when a match of the associated data is found in a database that contains the associated data, the associated data and the at least one fingerprint to be used in future identification of the recording. - View Dependent Claims (31, 32, 33)
