Abstract

A system and method for identifying media content presented over a media playing device. The media content, such as audio and/or video, is either available digitally or digitally sampled. The media content is sampled to generate a media sample or analytical representation of the media content. The media sample is compared to a collection of sampled (or represented) media content to identify it and to ascertain information related to the sample. This media content-related information is then presented to the user via a display means on the media player. The media player then presents the user specific and related actions that are based upon the information presented and allows the user to directly execute their choice of actions.

Claims

1. A method for identifying media content presented on a client media player comprising:

creating an analytical representation from a segment of media content on said client media player, wherein the media content is data for a work wherein said segment of said media content is a predetermined portion of said media content present on said media player and said analytical representation is a digital fingerprint of said segment;

comparing said analytical representation to a collection of analytical representations of reference sampled media content of known works to obtain content-related data of said work from said collection of analytical representations of reference sampled media content; and

presenting said content-related data on said client media player.

2. The method of claim 1, wherein said collection of analytical representations of reference sampled media content of known works is maintained in a lookup server in communication with said client media player, said method further comprising:

transmitting said analytical representation to a lookup server, before comparing said analytical representation to said collection of analytical representations of reference sampled media content; and

transmitting said content-related data to said client media player, before presenting said content-related data.

3. The method of claim 1 further comprising receiving a user-initiated command to identify said media content before creating an analytical representation of a segment of said media content.

4. The method of claim 1 wherein said creating an analytical representation of a segment of said media content of said work is carried out periodically.

5. The method of claim 1 wherein said creating an analytical representation of a segment of said media content of said work is carried out continuously.

6. The method of claim 1 wherein said creating an analytical representation of a segment of said media content further comprises maintaining a fixed buffer of media content of said work presented on said client media player.

7. The method of claim 1 wherein said creating an analytical representation of a segment of said media content further comprises creating a digital fingerprint of said media content presented on said client media player.

8. The method of claim 1 wherein said transmitting said analytical representation to a lookup server is carried out over an Internet connection.

9. The method of claim 1 wherein said transmitting said content-related data to said client media player is carried out over an Internet connection.

10. The method of claim 1 wherein said media content is audio content.

11. The method of claim 1 wherein said media content is video content.

12. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method of identifying media content presented on a client media player, said method comprising:

creating an analytical representation from a segment of media content of a work presented on said client media player, wherein the media content is data for a single work wherein said segment of said media content is a predetermined portion of said media content present on said media player and said analytical representation is a digital fingerprint of said segment;

comparing said analytical representation to a collection of analytical representations of reference sampled media content of known works to obtain content-related data of said work from said collection of analytical representations of reference sampled media content; and

presenting said content-related data of said work on said client media player.

13. The program storage device of claim 12, wherein said collection of analytical representations of reference sampled media content of known works is maintained in a lookup server in communication with said client media player, said method further comprising:

transmitting said analytical representation of said work to a lookup server, before comparing said analytical representation of said work to said collection of analytical representations of reference sampled media content; and

transmitting said content-related data of said work to said client media player, before presenting said content-related data.

14. In a network having at least one client media player operatively coupled for communication with a lookup server, a system for identifying media content presented on the client media player comprising:

client engine executing within the client media player, said client engine structured and configured to create an analytical representation from a segment of media content of a work presented on said client media player, wherein the media content is data for said work played on said client media player and communicate said sample to said lookup server;

a collection of analytical representations of reference sampled media content containing a plurality of analytical representations of sampled media content of know works, each associated with corresponding content-specific information; and

a server engine executing with said lookup server connected to said collection of analytical representations of sampled media content, said server engine structured and configured to receive said analytical representation of said work from said client media player and compare said received analytical representation with said plurality of analytical representations of sampled media content in said collection of analytical representations of reference sampled media content of known works to query and ascertain content information related to said received analytical representation, said server engine further structured and configured to transmit said content information to said client media player.

15. The system of claim 14 wherein said client engine is further structured and configured to display said content information.

16. The system of claim 14 wherein said media content is audio content.

17. The system of claim 14 wherein said media content is video content.

18. In a network having at least one client media player operatively coupled for communication with a lookup server, a client engine executing within the client media player for identifying media content presented on the client media player comprising:

an interrupt unit structured and configured to monitor the client media player for media content of a work presented thereon;

a sampling unit structured and configured to generate an analytical representation from a segment of media content of said work presented on said client media player, and transmit said analytical representation to said lookup server; and

a user interface structured and configured to receive content information related to said work from said lookup server and presenting said content information.

19. The client engine of claim 18, wherein said user interface is further structured and configured to receive user-requests from a user of said client media player, said sampling unit further structured and configured to generate said analytical representation upon receipt of said user request.

20. In a network having at least one client media player operatively coupled for communication with a lookup server, a server engine executing within the lookup server for identifying media content presented on the client media player comprising:

a collection of analytical representations of reference sampled media content containing a plurality of analytical representations of sampled media content of known works, each associated with corresponding content-specific information; and

a lookup unit coupled to said collection of analytical representations of reference sampled media content of known works, said lookup unit structured and configured to receive an analytical representation from a segment of media content of a recording presented on said client media player, wherein the media content is data for a single protected work of a recording played on said client media player and compare said received analytical representation with said plurality of analytical representations of sampled media content in said collection of analytical representations of reference sampled media content to query and ascertain content information related to said received analytical representation, said server engine further structured and configured to transmit said content information to said client media player.
