Systems and methods for improving server and client performance in fingerprint ACR systems

摘要

A system and method are disclosed that improve the efficiency and performance of an Automatic Content Recognition (ACR) system. Several approaches are described that may be used alone or in combination to reduce total system computational costs related to the manner in which such an ACR means takes samples, called “fingerprints,” of digital content being played by a television display device and transmits said fingerprints to a remote server to be compared to a database of fingerprints from known programming. Methods are described for implementing such system performance enhancement including varying sampling rates and other resolution metrics during the process of creating such fingerprints and transmitting them to the database server. The system and method disclosed also describes how to reduce the probability that, when compared to samples from already-identified programming, such fingerprints are incorrectly identified as being of programming other than that which they are in fact derived from.

1. A method, comprising:
determining one or more values related to transmitting fingerprints associated with a client to an Automated Content Recognition (ACR) system, the one or more values associated with one or more of at least one sampling rate, at least one pattern of sampling, at least one number of samples associated with creating a fingerprint package, or at least one time interval between fingerprint package transmissions; signaling to transmit one or more fingerprint packages associated with the client to the ACR system based at least partially on the one or more values; identifying at least one of a channel or a video segment associated with the client based at least partially on one or more transmitted fingerprint packages; and determining whether the at least one of the identified channel or the identified video segment is at least one of a channel of interest or a video segment of interest and, if the at least one of the identified channel or the identified video segment is at least one of a channel of interest or a video segment of interest, adjusting at least one of the one or more values related to transmitting fingerprints wherein the adjusted one or more values are operable to transmit fingerprint packages enabling ACR detection sufficiently fast for providing at least some context-sensitive content substantially simultaneously with at least one targeted video.
