A system for monitoring and recognizing audio broadcasts is described. The system includes a plurality of geographically distributed monitoring stations, each of the monitoring stations receiving unknown audio data from a plurality of audio broadcasts. A recognition system receives the unknown audio data from the plurality of monitoring stations and compares the unknown audio data against a database of signature files. The database of signature files, or index sets, corresponds to a library of known audio files, such that the recognition system is able to identify known audio files in the unknown audio stream as a result of the comparison. The system further includes a nervous system able to monitor and configure the plurality of monitoring stations and the recognition system, and a heuristics and reporting system able to analyze the results of the comparison performed by the recognition system and use metadata associated with each of the known audio files to generate a report of the contents of plurality of audio broadcasts.
L'invention concerne un système de surveillance et de reconnaissance de diffusions générales audio. Le système comprend une pluralité de stations de surveillance géographiquement réparties, chacune des stations de surveillance recevant des données audio inconnues d'une pluralité de diffusions générales audio. Un système de reconnaissance reçoit les données audio inconnues de la pluralité de stations de surveillance et compare les données audio inconnues à une base de données de fichiers de signature. La base de données de fichiers de signature, ou ensembles d'index, correspond à une bibliothèque de fichiers audio connus, de sorte que le système de reconnaissance peut identifier les fichiers audio connus dans le flux audio inconnu à la suite de la comparaison. Le système comprend en outre un système nerveux pouvant surveiller et configurer la pluralité de stations de surveillance et le système de reconnaissance, et un système heuristique et de création de rapport pouvant analyser les résultats de la comparaison effectuée par le système de reconnaissance et utiliser les métadonnées associées à chacun des fichiers audio connus pour générer un rapport des contenus de la pluralité de diffusions générales audio.
