Abstract

Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based on a determination that a segment of the fingerprint data matches a reference fingerprint corresponding with just a single channel, such as a reference fingerprint representing commercial or news programming content specific to just the single channel. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action.

Claims20

Dependent claims

A method comprising:

determining by a computing system that digital fingerprint data representing a first segment of media content being rendered by a media presentation device matches multiple instances of reference fingerprint data each corresponding with a different respective channel;
after determining that the digital fingerprint data representing the first segment of media content being rendered by the media presentation device matches the multiple instances of reference fingerprint data each corresponding with a different respective channel, performing by the computing system disambiguation based at least in part on an earlier determination that digital fingerprint data representing a second segment of the media content being rendered by the media presentation device matches reference fingerprint data corresponding with just a single channel, the disambiguation establishing that the media presentation device is receiving the media content on the single channel, wherein the second segment of the media content being rendered by the media presentation device is before the first segment of the media content being rendered by the media presentation device;
and
taking action by the computing system based on the establishing that the media presentation device is receiving the media content on the single channel.

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

determining that digital fingerprint data representing a first segment of media content being rendered by a media presentation device matches multiple instances of reference fingerprint data each corresponding with a different respective channel;
after determining that the digital fingerprint data representing the first segment of media content being rendered by the media presentation device matches the multiple instances of reference fingerprint data each corresponding with a different respective channel, performing disambiguation based at least in part on an earlier determination that digital fingerprint data representing a second segment of the media content being rendered by the media presentation device matches reference fingerprint data corresponding with just a single channel, the disambiguation establishing that the media presentation device is receiving the media content on the single channel, wherein the second segment of the media content being rendered by the media presentation device is before the first segment of the media content being rendered by the media presentation device;
and
causing action to be taken based on the establishing that the media presentation device is receiving the media content on the single channel.
