Methods and systems for processing a sample of a media stream
First Claim
1. A method comprising:
- receiving, at a computing device, a signature stream including a temporally mapped collection of features describing content of a media stream, wherein the features are extracted from the media stream;
performing a content identification of content in a first portion of the signature stream against a reference database of media content resulting in an identification of reference media recordings including the content so as to determine a recognition result of the content identification;
for the reference media recordings identified from the content identification, receiving at the computing device a signature file including a temporally mapped collection of features describing content of the identified reference media recordings, wherein the features in the signature file are anticipated to appear in the signature stream at predetermined times;
comparing, by the computing device, features between a second portion of the signature stream and a given signature file for at least one identified reference media recording, wherein the second portion of the signature stream differs from the first portion; and
based on the comparison, verifying the continuity of match between the media stream and the identified reference media recording.

Abstract
Methods and systems for processing a sample of a media stream are provided. In one example, a method includes receiving a sample of a media stream rendered by a media rendering source, and for matching media recordings from which the sample was obtained, the method also includes receiving a signature file including a temporally mapped collection of features describing content of the matching media recordings. Each received signature file may be stored in memory. In addition, a signature stream may be received that includes features extracted from the media stream, and a number of matching features between the signature stream of the media stream and the signature file for at least one matching media recording can be determined. In one example, when substantially matching features between the signature stream of the media stream and the signature file for a matching media recording stop occurring, a discontinuity can be identified.

39. An article of manufacture including a tangible non-transitory computer-readable media having computer-readable instructions encoded thereon, the instructions comprising:
-
instructions for receiving a signature stream including a temporally mapped collection of features describing content of a media stream, wherein the features are extracted from the media stream; instructions for performing a content identification of content in a first portion of the signature stream against a reference database of media content resulting in an identification of reference media recordings including the content so as to determine a recognition result of the content identification; for the reference media recordings identified from the content identification, instructions for receiving a signature file including a temporally mapped collection of features describing content of the identified reference media recordings, wherein the features in the signature file are anticipated to appear in the signature stream at predetermined times; instructions for comparing features between a second portion of the signature stream and a given signature file for at least one identified reference media recording, wherein the second portion of the signature stream differs from the first portion; and instructions for, based on the comparison, verifying the continuity of match between the media stream and the identified reference media recording. - View Dependent Claims (40, 41, 42)

43. A system comprising:
-
an input interface configured to receive a signature stream including a temporally mapped collection of features describing content of a media stream, wherein the features are extracted from the media stream; a module that performs a content identification of content in a first portion of the signature stream against a reference database of media content resulting in an identification of reference media recordings including the content so as to determine a recognition result of the content identification; and a continuity tracker configured to receive, for the reference media recordings identified from the content identification, a signature file including a temporally mapped collection of features describing content of the identified reference media recordings, wherein the features in the signature file are anticipated to appear in the signature stream at predetermined times, wherein the continuity tracker is further configured to compare features between a second portion of the signature stream and a given signature file for at least one identified reference media recording, and based on the comparison, verify the continuity of match between the media stream and the identified reference media recording, wherein the second portion of the signature stream differs from the first portion. - View Dependent Claims (44, 45, 46)
