Abstract
Disclosed are methods and systems to help disambiguate channel identification in a scenario where a video fingerprint of media content matches multiple reference video fingerprints corresponding respectively with multiple different channels. Given such a multi-match situation, an entity could disambiguate based on an audio component of the media content, such as by further determining that an audio fingerprint of the media content at issue matches an audio fingerprint of just one of the multiple channels, thereby establishing that that is the channel on which the media content being rendered by the media presentation device is arriving.
Claims20
A system comprising:
- a network communication interface;
- at least one processing unit;
- non-transitory data storage;
- and
- program instructions stored in the non-transitory data storage and executable by the at least one processing unit to carry out operations including:
- determining that digital video fingerprint data representing media content being rendered by a media presentation device matches reference video fingerprint data corresponding with multiple channels,
- responsive to at least the determining that the digital video fingerprint data matches the reference video fingerprint data corresponding with the multiple channels, performing disambiguation based at least in part on a determination that digital audio fingerprint data representing the media content being rendered by the media presentation device matches reference audio fingerprint data corresponding with just a single channel of the multiple channels, the disambiguation establishing that the media content being rendered by the media presentation device is media content of the single channel, and
- taking action based on the establishing that the media content being rendered by the media presentation device is media content of the single channel.
A non-transitory computer readable medium storing instructions executable by at least one processing unit to carry out operations including:
- determining that digital video fingerprint data representing media content being rendered by a media presentation device matches reference video fingerprint data corresponding with multiple channels;
- responsive to at least the determining that the digital video fingerprint data matches the reference video fingerprint data corresponding with the multiple channels, performing disambiguation based at least in part on a determination that digital audio fingerprint data representing the media content being rendered by the media presentation device matches reference audio fingerprint data corresponding with just a single channel of the multiple channels, the disambiguation establishing that the media content being rendered by the media presentation device is media content of the single channel;
- and
- taking action based on the establishing that the media content being rendered by the media presentation device is media content of the single channel.
