Patent Images
1. A method for identifying a broadcast stream, comprising:
- receiving one or more broadcast streams;
generating and storing a fingerprint of a selected portion of the one or more broadcast streams;
receiving a query from a device;
generating a fingerprint of the query;
identifying content from the query, using the fingerprint of the query and a database of indexed content; and
identifying a source of the query using the fingerprint of the query and the stored fingerprints.

Abstract
A user (102) hears an audio program being broadcast and can record a sample of the audio. The sample is then conveyed to an analyzing means (106) to determine to which broadcast station the user is listening. The analyzing means monitors many broadcast channels. Thus, characteristics of the audio sample and samples taken from the broadcast channels can be compared to find a match. Broadcast information pertaining to the broadcast channel from which the match was found may then be reported back to the user, combined with an advertisement of a promotion, prize notification, discount offers, and other information specific for a certain radio station for example.

7. A method for identifying a broadcast stream, comprising:
-
receiving one or more broadcast streams; generating and storing a fingerprint of a selected portion of the one or more broadcast streams, together with extracted information from the one or more broadcast streams; receiving a query; generating a fingerprint of the query; attempting to match the query fingerprint to the stored fingerprints; identifying content of the query and a source of the query, using information from the stored fingerprints and the stored extracted information, and a database of indexed content; and processing results of the identifying operation to identify a broadcast stream match or a content match. - View Dependent Claims (8, 9, 10, 11, 12, 13)
