Methods for Identifying Audio or Video Content
First Claim
Patent Images
1. A recognition method useful in matching a first item of visual or audio entertainment content to a counterpart in a universe of second items of visual or audio entertainment content, comprising:
- receiving fingerprint data derived from first visual or audio entertainment content;
identifying plural items of second content that are possible matches of said first content, based on the received fingerprint data;
sending to each of one or more human reviewers at least a portion of the first content item, and at least a portion of one of the second content items;
collecting assessment data from said one or more reviewers; and
using said assessment data in identifying one of said items of second entertainment content that appears to be a best match with said first entertainment content item.

Abstract
The disclosed technology generally relates to methods for identifying audio and video entertainment content. Certain shortcomings of fingerprint-based content identification can be redressed through use of crowdsourcing techniques.

4. A recognition method useful in matching a first item of visual or audio entertainment content to a counterpart in a universe of second items of entertainment content, comprising:
-
sending to a human reviewer, over a computer network, at least a portion of the first entertainment content item; collecting assessment data from said reviewer; using said assessment data to prune the universe of second entertainment content items to a smaller subset; and searching for a counterpart to the first item of entertainment content in the smaller subset of second entertainment content items. - View Dependent Claims (5)

6. A method comprising:
-
distributing task data to plural humans over a computer network, the task data being unrelated to facial recognition; collecting task result data from said humans, over the network; and taking into account respective expertises of different of said humans in using said task result data. - View Dependent Claims (7)

8. A method comprising:
-
computing a fingerprint from first audio or visual entertainment content; checking a database for a match between said computed fingerprint and a collection of reference fingerprints; in at least certain cases, referring the first entertainment content to one or more human reviewers over a computer network, for an assessment; and storing assessment data received from the one or more human reviewers in a database, in association with said computed fingerprint, for later reference.

9. A method of processing audio or visual entertainment content to yield a fingerprint identifier different than a fingerprint identifier associated with said entertainment content in an unprocessed state, comprising at least one of the following (a)-(f):
-
(a) applying to said entertainment content a non-flat frequency equalization process; (b) applying to said entertainment content a frequency equalization process that changes over time; (c) changing the dynamic range of at least certain frequency bands of said entertainment content; (d) altering the entertainment content in a manner exploiting temporal- or frequency-psychoacoustic masking phenomena; (e) varying the entertainment content in a manner to exploit threshold biasing phenomena; and
/or(f) processing the entertainment content so that it has an attribute placing it in a classification of entertainment content that is pruned from consideration as a fingerprint match; wherein the processed entertainment content may escape recognition by automated techniques adapted to recognize the entertainment content in its unprocessed state.

10. A method comprising:
-
sending first and second items of data to each of one or more human reviewers, over a computer network, said items being unrelated to verifying a person'"'"'s identity; soliciting an assessment from said one or more reviewers as to whether the first and second of items should be deemed to match, despite a difference therebetween; receiving assessment data from said one or more human reviewers; and using said assessment data in an automated process.
