Generation of a media content database by correlating repeating media content in media streams
First Claim
Patent Images
1. A method for creating and maintaining a media content database, the method comprising:
- sampling a first media stream to obtain a first set of samples, each sample including characteristic information for a segment of the first media stream;
sampling a second media stream to obtain a second set of samples, each sample including characteristic information for a segment of the second media stream;
matching at least some of the second set of samples against the first set of samples;
receiving identifying information for the matched samples; and
storing the matched samples and their corresponding identifying information in the media content database.

Abstract
A media content database is created and maintained by comparing the media items from two related media streams. Segments of media items from the streams are sampled and stored. Samples from one stream are matched against samples from the other stream to identify any repeating content in the streams. A reviewer observes the matched samples representing the repeating content and provides identifying meta-data for that content. The identified media content is then added to the media content database, where it can be used at a later time in an application that requires media content recognition.

9. A method for generating entries for a media content database, the method comprising:
-
receiving a first media stream;
receiving a second media stream;
matching at least some portions of the second media stream to the first media stream to determine repeating content between the streams; and
presenting the repeating content to a reviewer for identification. - View Dependent Claims (10, 11, 12, 13, 14)
