Patent ID: 8090579

Claim:
A method of recognizing repeated audio material within at least one media stream without prior knowledge of the nature of the repeated material, comprising: receiving a sample audio fragment from the at least one media stream; determining, via a processor, whether the sample audio fragment matches an entry in a database of known media samples, wherein the sample audio fragment is an unknown sample when the sample audio fragment does not match an entry in the database; determining whether the unknown sample matches an unknown audio fragment indexed in a screening database; recording a match between the unknown sample and the unknown audio fragment when, based on the determination, the unknown sample matches the unknown audio fragment; determining whether the unknown sample is ready to be published for identification and inclusion into the database of known media samples based on repeated matches between the unknown sample and the unknown audio fragment; and publishing the unknown sample for identification and inclusion into the database of known media samples when the repeated matches exceed a threshold.
