Abstract

Methods and systems for identifying information of a broadcast station and information of broadcasted content are provided. In one example, a method includes receiving at a client device media content rendered by a media rendering source, and the client device making an attempt to determine an identity of the media content based on information stored on the client device. The method also includes based on the attempt of the client device to determine the identity of the media content, determining an identity of the media rendering source. The method further includes based on the attempt of the client device to determine the identity of the media content and on determining the identity of the media rendering source, sending information indicative of the media content to a content recognition server to determine the identity of the media content.

Claims

1. A method comprising:

receiving at a client device media content rendered by a media rendering source;

the client device first making an attempt to determine an identity of the media content based on information stored on the client device by comparing characteristics of the media content with one or more signature files of media content stored on the client device to determine a match, wherein the one or more signature files are each indicative of one or more features extracted from reference media content and corresponding information identifying the reference media content;

based on the attempt of the client device to determine the identity of the media content using the information stored on the client device being unsuccessful due to the client device lacking a matching signature file stored on the client device, the client device then making an attempt to determine an identity of the media rendering source; and

based on the attempt of the client device to determine the identity of the media content and on the attempt of the client device to determine the identity of the media rendering source both being unsuccessful, the client device sending a sample of the media content to a content recognition server and requesting the content recognition server to determine the identity of the media content.

2. The method of claim 1, wherein determining the identity of the media rendering source comprises:

sending information indicative of the media content to a broadcast identification server to determine the identity of the media rendering source; and

receiving information indicative of the identity of the media rendering source from the broadcast identification server.

3. The method of claim 2, further comprising also receiving from the broadcast identification server information indicative of the identity of the media content.

4. The method of claim 2, further comprising the client device making an attempt to determine the identity of the media content based on reference to a playlist of content rendered by the media rendering source.

5. The method of claim 4, wherein the playlist of content rendered by the media rendering source is stored on the client device.

6. The method of claim 1, wherein determining the identity of the media rendering source comprises:

sending information indicative of the media content to a broadcast identification server to determine the identity of the media rendering source; and

wherein based on determining the identity of the media rendering source comprises based on receiving information indicative of the identity of the media rendering source from the broadcast identification server.

7. The method of claim 1, wherein determining the identity of the media rendering source comprises the client device determining the identity of the media rendering source based on a temporal comparison of characteristics of the media content with characteristics of a source sample taken from content rendered by the media rendering source.

8. The method of claim 1, wherein a given signature file includes a temporally mapped collection of the one or more features extracted the given media content, wherein each of the one or more features describes the given media content in a vicinity of a mapped timepoint.

9. The method of claim 1, wherein the client device determining the identity of the media content based on information stored on the client device comprises:

determining one or more features of the received media content; and

comparing the one or more features of the received media content with the one or more features extracted from reference media content as indicated by the one or more signature files to determine a match of one or more features.

10. The method of claim 1, wherein receiving at the client device media content rendered by the media rendering source comprises receiving the media content at the client device using a microphone of the client device.

11. A non-transitory computer readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions comprising:

receiving media content rendered by a media rendering source;

the computing device first making an attempt to determine an identity of the media content based on information stored on the computing device by comparing characteristics of the media content with one or more signature files of media content stored on the computing device to determine a match, wherein the one or more signature files are each indicative of one or more features extracted from reference media content and corresponding information identifying the reference media content;

based on the attempt of the computing device to determine the identity of the media content using the information stored on the computing device being unsuccessful due to the computing device lacking a matching signature file stored on the computing device, the computing device then making an attempt to determine an identity of the media rendering source; and

based on the attempt of the computing device to determine the identity of the media content and on the attempt of the computing device to determine the identity of the media rendering source both being unsuccessful, the computing device sending a sample of the media content to a content recognition server and requesting the content recognition server to determine the identity of the media content.

12. The non-transitory computer readable medium of claim 11, wherein determining the identity of the media rendering source comprises:

sending information indicative of the media content to a broadcast identification server to determine the identity of the media rendering source; and

receiving information indicative of the identity of the media rendering source from the broadcast identification server.

13. A device comprising:

a database configured to receive and store one or more signature files of media content that are each indicative of one or more features extracted from reference media content and information identifying the reference media content; and

a content identification module, including one or more processors executing instructions stored on non-transitory computer readable media, coupled to the database and configured to (i) make an attempt to determine an identity of received media content rendered by a media rendering source by comparing characteristics of the media content with the one or more signature files of media content stored on the database to determine a match, (ii) based on the attempt to determine the identity of received media content being unsuccessful due to lacking a matching signature file stored on the database, to then make an attempt to determine an identity of the media rendering source, and (iii) based on the attempt to determine the identity of the received media content and on the attempt to determine the identity of the media rendering source both being unsuccessful, to send a sample of the media content to a content recognition server and request the content recognition server to determine the identity of the media content.

14. The device of claim 13, wherein the database is configured to store a playlist of content rendered by the media rendering source, and wherein the content identification module is further configured to attempt to determine the identity of the media rendering source based on reference to the playlist of content rendered by the media rendering source.
