Method and System for Identification of Distributed Broadcast Content

摘要

A method and system of performing high-throughput identifications of broadcast content is provided. A device can send a content identification query, which includes a sample of content being broadcast, to a server to request an identity of the content. The server will perform a computational identification of the content, return the result to the device, and store the result. For all subsequently received content identification queries requesting an identity of content being broadcast from the same source and in a time during which the content is still being broadcast from the source, the server will send the stored content identification in response to the subsequent queries. If a subsequent content identification query does not request the identity of content being broadcast from the same source or is not received during the time that the content is still being broadcast, the server will perform a computational identification of a content sample.

1. A method of identifying an audio content sample and determining a broadcast station source for a broadcast, including:
monitoring a plurality of broadcast stations and identifying broadcast audio content from the broadcast stations as the broadcast audio content is received; caching to memory fingerprints of the identified broadcast audio content from the plurality of broadcast stations; receiving a sampled audio content; matching fingerprints of the sampled audio content against:
the cache of fingerprints from the identified broadcast audio content; anda database of audio content; identifying the sampled audio content and, when the sampled audio content originates from a broadcast, a broadcast station source that was sampled; receiving a location from a portable device; and using at least the location and the identified sampled audio content to target the portable device for advertising or offers.
