Program and Syndicated Content Detection

摘要

Content from multiple different stations can be divided into segments based on time. Matched segments associated with each station can be identified by comparing content included in a first segment associated with a first station, to content included in a second segment associated with a second station. Syndicated content can be identified and tagged based, at least in part, on a relationship between sequences of matched segments on different stations. Various embodiments also include identifying main sequences associated with each station under consideration, removing some of the main sequences, and consolidating remaining main sequences based on various threshold criteria.

主权项

1. A method for use in a syndicated content recognition system, the method comprising:
retrieving station-specific media content broadcast by a plurality of media broadcast stations from at least one database used by an automated radio broadcasting system; dividing the station-specific media content associated with individual media broadcast stations into sequences of buckets having equal time durations; identifying a main sequence associated with a first media broadcast station included in the plurality of media broadcast stations, the main sequence including a first contiguous sequence of buckets that matches corresponding contiguous sequences of buckets associated with at least a predetermined number of the plurality of media broadcast stations; identifying secondary sequences associated with the other media broadcast stations, the secondary sequences including contiguous sequences of buckets that match corresponding contiguous sequences of buckets associated with at least the predetermined number of the plurality of media broadcast stations; comparing the main sequence to individual secondary sequences to determine whether the main sequence includes at least a threshold amount of content in common with the individual secondary sequences; and identifying syndicated content based, at least in part, on the comparing.
