Patent number: 9871606Abstract: A real time messaging platform identifies an audio snippet of a time-based media (TBM) event. The messaging platform maintains a real time repository of concurrently broadcasting TBM events as well as a historical repository of previously broadcast TBM events. These repositories contain acoustic fingerprints of their respective TBM events. The messaging platform matches an acoustic fingerprint of the audio snippet with one of the stored acoustic fingerprints to identify the TBM event in the recorded snippet. To identify the TBM event, the messaging platform matches multiple overlapping reference audio segments of the reference audio stream with multiple test audio segments of the audio snippet. This allows the platform to account for time delays between the test and reference audio segments that would otherwise hinder the matching process.Type: GrantFiled: May 13, 2014Date of Patent: January 16, 2018Assignee: Twitter, Inc.Inventors: Andrew John Carroll, Jeremy Rishel, Richard Douglas Whitcomb, Jr., Mark Watabe, Noah Vihinen, Indranrita Deshmukh, Artur B.
