SELECTING CONTENT BASED ON MEDIA DETECTED IN ENVIRONMENT

1 . A method to select content based on ambient media detection, comprising:

using a processor, a received set of audio features associated with an audio environment, and a stored media signature data to detect, based at least in part on the set of audio features, a media channel and program that is being played in the audio environment;

using the processor and stored data associating one or more advertising or other classification codes with the detected media channel and program to determine an advertising or other classification code; and

using the processor and the determined advertising or other classification codes to select and provide to a target device associated with the audio environment a secondary content.

2 . The method of claim 1 , wherein the stored media signature data is generated and stored in or near real time as a media stream associated with the detected media channel and program is being distributed via one or more distribution nodes to consumers of the media channel.

3 . The method of claim 2 , wherein the stored media signature data is generated at least in part by extracting from the media stream a media stream feature set corresponding to the feature set associated with the audio environment.

4 . The method of claim 1 , wherein the stored data associating one or more advertising or other classification codes with the detected media channel and program is generated and stored in or near real time as a media stream associated with the detected media channel and program is being distributed via one or more distribution nodes to consumers of the media channel.

5 . The method of claim 4 , wherein the stored data associating one or more advertising or other classification codes with the detected media channel and program is generated at least in part by extracting text-based content from the media stream.

6 . The method of claim 5 , wherein extracting text-based content from the media stream includes extracting one or more of closed caption, subtitle, or other text-based content from the media stream.

7 . The method of claim 5 , wherein the text-based content is processed to determine one or more topics with which the media stream is associated.

8 . The method of claim 7 , wherein the one or more topics are used to determine said one or more advertising or other classification codes.

9 . The method of claim 1 , wherein the target device comprises a client device that provided the set of audio features associated with the audio environment.

10 . The method of claim 9 , wherein the secondary content comprises advertising content.

11 . The method of claim 9 , wherein the secondary content comprises application content.

12 . The method of claim 11 , wherein the application content is associated with an application used to extract and provide said set of audio features associated with the audio environment.

13 . The method of claim 1 , wherein the secondary content is selected based at least in part on a user profile data.

14 . A system to select content based on ambient media detection, comprising:

a communication interface; and

is a processor coupled to the communication interface and configured to:

use a received set of audio features associated with an audio environment and a stored media signature data to detect, based at least in part on the set of audio features, a media channel and program that is being played in the audio environment;

use stored data associating one or more advertising or other classification codes with the detected media channel and program to determine an advertising or other classification code; and

use the determined advertising or other classification codes to select and provide to a target device associated with the audio environment a secondary content.

15 . The system of claim 14 , wherein the stored media signature data is generated and stored in or near real time as a media stream associated with the detected media channel and program is being distributed via one or more distribution nodes to consumers of the media channel.

16 . The system of claim 15 , wherein the stored media signature data is generated at least in part by extracting from the media stream a media stream feature set corresponding to the feature set associated with the audio environment.

17 . The system of claim 14 , wherein the stored data associating one or more advertising or other classification codes with the detected media channel and program is generated and stored in or near real time as a media stream associated with the detected media channel and program is being distributed via one or more distribution nodes to consumers of the media channel.

18 . The system of claim 17 , wherein the stored data associating one or more advertising or other classification codes with the detected media channel and program is generated at least in part by extracting text-based content from the media stream.

19 . The system of claim 18 , wherein extracting text-based content from the media stream includes extracting one or more of closed caption, subtitle, or other text-based content from the media stream.

20 . A computer program product to select content based on ambient media detection, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

using a processor, a received set of audio features associated with an audio environment, and a stored media signature data to detect, based at least in part on the set of audio features, a media channel and program that is being played in the audio environment;

using the processor and stored data associating one or more advertising or other classification codes with the detected media channel and program to determine an advertising or other classification code; and

using the processor and the determined advertising or other classification codes to select and provide to a target device associated with the audio environment a secondary content.
