Abstract: Disclosed herein are system, method, and computer program product embodiments for a computing system with a content-characteristic based trigger feature. An embodiment operates by determining a hybrid system of transmitting a fingerprint of media is being used to transmit one or more media fingerprints. A first fingerprint is generated from a first portion of media content and a second fingerprint is generated from of a second portion of the media content. It is determined that the first portion of media content and the second portion of the media content lack a threshold extent of similarity with each other. The second fingerprint is provided to a content identification server to identify the second portion of the media content. An action is performed based on an identified second portion of the media content.

Abstract: In one aspect, an example method includes receiving, by a computing system, media content; generating, by the computing system, a fingerprint of the received media content; determining, by the computing system, that a channel-change operation was performed; responsive to determining that the channel-change operation was performed, transmitting, by the computing system, the generated fingerprint to a content identification server to identify the received media content; and performing an action based on the identified media content.

Abstract: A query fingerprint of a set of frames of video content captured at a client device may be generated. Multiple patches of the set of frames of video content may be selected and a value calculated for each of the selected multiple patches. The value for each patch may be indicated as a single bit along with an additional 1-bit value to indicate whether the patch value is weak. A database of known reference fingerprints may be queried using the generated query fingerprint. Matches between the query fingerprint and the reference fingerprints may be identified. Weak bits may be given reduced weight in identifying the match of fingerprints. Based on the matches, an identifier for the video content may be returned to the client device. The client device may use the received identifier to access the supplemental content.
