Method and system for determining frame certainty for automatic content recognition

摘要

A method for determining a frame certainty metric 340 for automatic content recognition comprises media device frames F of a media device stream S with respect _{to broadcast frames F 1-n of a broadcast media stream SD1-n} ) and determining whether to move the frame match by: a first media device fingerprint 222b and a target broadcast fingerprint ( 222 _TB ) based on a first frame certainty metric; a second media device fingerprint sequentially adjacent to the first media device fingerprint and a second frame certainty metric based on the target broadcast fingerprint; a third media device fingerprint sequentially adjacent to the first media device fingerprint and a third frame certainty metric based on the target broadcast fingerprint; and maximum frame certainty metric. The method further includes identifying the maximum frame certainty metric as a target media device fingerprint 222 _{TM that matches the target broadcast fingerprint.}
