Acquisition, recovery, and matching of unique information from file-based media for automated file detection

摘要

A media fingerprint archive system generates and archives media fingerprints from second media content portions such as commercials. A downstream media measurement system can extract/derive query fingerprints from an incoming signal, and query the media fingerprint archive system whether any of the query fingerprints matches any archived fingerprints. If so, the media measurement system can perform media measurements on a specific secondary media content portion from which the matched query fingerprint is derived. If not, the media measurement system can analyze media characteristics of a media content portion to determine whether the media content portion is a secondary media content portion and perform media measurement if needed to. The media measurement system may send fingerprints from an identified secondary media content portion to the media fingerprint archive system for storage.

1. A method, comprising:
extracting a plurality of query fingerprints from media data that comprises one or more primary media content portions embedded with one or more secondary media content portions; wherein the media data is received in one of an over-the-air broadcast signal, a cable broadcast signal, a satellite broadcast signal, a media data bitstream, or a media data file; sending a plurality of fingerprint identification queries to a media fingerprint archive system, each fingerprint identification query in the plurality of fingerprint identification queries comprising at least one query fingerprint in the plurality of query fingerprints; receiving a plurality of fingerprint identification responses from the media fingerprint archive system, each fingerprint identification response in the plurality of fingerprint identification responses being responsive to a corresponding fingerprint query in the plurality of fingerprint identification queries, and each fingerprint identification response in the plurality of fingerprint identification responses indicating a positive fingerprint identification or a negative fingerprint identification; in response to receiving at least one positive fingerprint identification response in the plurality of fingerprint identification responses from the media fingerprint archive system:
identifying a first secondary media content portion of the one or more secondary media content portions embedded within the one or more primary media content portions;performing a first set of media measurements on the first secondary media content portion of the one or more secondary media content portions embedded within the one or more primary media content portions;controlling at least one media characteristic of the first secondary media content portion in response to receiving the at least one positive fingerprint identification in the plurality of fingerprint identification responses from the media fingerprint archive system;wherein the at least one media characteristic comprises loudness; wherein the method is performed by one or more computing devices.
