Claim of US Patent No. 10,045,073

1. A method comprising:determining, by a computing system, that a fingerprint of media content being rendered by a media presentation device matches multiple reference fingerprints each corresponding with a different respective channel;
responsive to determining that the fingerprint matches the multiple reference fingerprints each corresponding with a different respective channel, performing disambiguation based at least in part on a time of broadcast of the media content being rendered by the media presentation device, to determine which channel the media presentation device is receiving the media content on; and
taking action based on the determined channel,
wherein performing disambiguation based at least in part on the time of broadcast of the media content being rendered by the media presentation device comprises determining the time of broadcast of the media content being rendered by the media presentation device and using the determined time of broadcast of the media content being rendered by the media presentation device as a basis to determine which one of the matching reference fingerprints corresponds with the channel on which the media presentation device is receiving the media content,
wherein each of the matching reference fingerprints has a corresponding time of broadcast, and wherein using the determined time of broadcast of the media content being rendered by the media presentation device as a basis to determine which one of the matching reference fingerprints corresponds with the channel on which the media presentation device is receiving the media content comprises (i) comparing the determined time of broadcast of the media content being rendered by the media presentation device with each matching reference fingerprint's corresponding time of broadcast, and (ii) determining based on the comparing that the time of broadcast of the media content being rendered by the media presentation device matches just the time of broadcast corresponding with the one matching reference fingerprint.
