Media Channel Identification with Video Multi-Match Detection and Disambiguation Based on Audio Fingerprint

A non-transitory computer readable medium having stored thereon instructions executable by a processing unit to carry out operations comprising:

• determining that a video fingerprint of media content being rendered by a media presentation device matches multiple reference video fingerprints each corresponding with a different respective channel;
• responsive to at least determining that the video fingerprint matches the multiple reference video fingerprints each corresponding with a different respective channel, performing disambiguation based at least in part on a determination that an audio fingerprint of the media content being rendered by the media presentation device matches a reference audio fingerprint corresponding with just a single channel, the disambiguation establishing that the media presentation device is receiving the media content on the single channel;
• and
• taking action based on the establishing that the media presentation device is receiving the media content on the single channel.

A system comprising:

• a network communication interface;
• a processing unit;
• non-transitory data storage;
• and
• program instructions stored in the non-transitory data storage and executable by the processing unit to carry out operations including:
• receiving from a media presentation device, via the network communication interface, a video fingerprint of media content being rendered by the media presentation device,
• determining that the received video fingerprint matches reference video fingerprints corresponding with multiple channels,
• receiving from the media presentation device, via the network communication interface, an audio fingerprint of the media content being rendered by the media presentation device,
• using the received audio fingerprint to determine which of the multiple channels carries the media content being rendered by the media presentation device, and
• taking action based on the determined channel.
