Media Channel Identification and Action, with Disambiguation Through Client-Side Fingerprint Matching of Channel-Specific Icon

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:
• detecting that query fingerprint data representing frames of video content being rendered by a media presentation device matches reference fingerprint data representing frames of multiple channels of video content, including detecting that the query fingerprint data matches multiple instances of reference fingerprint data each representing frames of a different respective channel in the multiple channels of video content, and
• responsive to at least the detecting that the query fingerprint data representing the frames of the video content being rendered by the media presentation device matches the reference fingerprint data representing the frames of the multiple channels of video content, configuring the media presentation device with channel-icon fingerprint data representing channel icons of the multiple channels of video content, to enable the media presentation device to perform channel-icon fingerprint matching to determine which channel of the multiple channels is being rendered by the media presentation device.
