Abstract

User exposure to media items is detected and measured. A mobile client device carried by a user digitally samples the audio environment of the user on a regular basis. These samples are transformed into a stream of data signatures and compared with reference media items to detect user exposure to the reference items. Purchase behavior following exposure to selected media content items can be detected and tracked as well, so as to gauge effectiveness of media items such as advertisements.

Claims

1. A system for detecting user exposure to media items, comprising:

a server, for receiving a plurality of reference media items from at least one media receiver;

at least one stream collection server, for receiving a representation of at least one target media item from at least one client device;

a correlator server, coupled to the stream store, for identifying one of the reference media items as corresponding to the target media item; and

an output device, coupled to the correlator server, for generating output signaling user exposure to the identified reference media item;

wherein the plurality of reference media items comprises at least one broadcast, and wherein the representation of at least one target media item indicates user exposure at a time other than the time of the broadcast.

4. A system for detecting user exposure to media items, comprising:

a server, for receiving a plurality of reference media items from at least one media receiver;

at least one stream collection server, for receiving a representation of at least one target media item from at least one client device;

a stream store, coupled to the server and to the at least one stream collection server, for storing a representation of at least a subset of the received reference media items and for storing a representation of the at least one target media item;

a correlator server, coupled to the stream store, for identifying one of the reference media items as corresponding to the target media item;

an output device, coupled to the correlator server, for generating output signaling user exposure to the identified reference media item; and

a purchasing tracking server, for receiving consumer purchasing information;

wherein the output device generates a report correlating user purchasing information with user exposure to the identified reference media item.

5. The system of claim 4, wherein the purchasing tracking server receives at least one indication of user use of a credit card.

6. A system for detecting user exposure to media items, comprising:

a server, for receiving a plurality of reference media items from at least one media receiver;

a plurality of stream collection servers for receiving a representation of at least one target media item from at least one client device;

a stream store, coupled to the server and to the stream collection servers, for storing a representation of at least a subset of the received reference media items and for storing a representation of the at least one target media item;

a correlator server, coupled to the stream store, for identifying one of the reference media items as corresponding to the target media item;

an output device, coupled to the correlator server, for generating output signaling user exposure to the identified reference media item; and

a stream collection server selector, for selecting, based on at least one of load and geographic proximity to the client device, one of the plurality of data signature stream collection servers to receive the representation of at least one target media item.

7. A method for detecting user exposure to media items, comprising:

receiving a plurality of reference media items from at least one media source;

for at least one client device;

selecting, based on at least one of load and geographic proximity to the client device, one of a plurality of data signature stream collection servers; and

at the selected data signature stream collection server, receiving, from the client device;

a representation of at least one target media item; and

an indication as to whether the client device is in the physical possession of a person at a time of exposure to the target media item; and

responsive to an indication that the client device is in the physical possession of a person at the time of exposure to the target media item;

identifying one of the reference media items as corresponding to the target media item; and

generating output signaling user exposure to the identified reference media item.

8. The method of claim 7, further comprising:

responsive to an indication that the client device is not in the physical possession of a person at the time of exposure to the target media item, ignoring the representation of the at least one target media item from the client device.

9. The method of claim 7, further comprising:

responsive to an indication that the client device is not in the physical possession of a person at the time of exposure to the target media item;

identifying one of the reference media items as corresponding to the target media item; and

generating output signaling user exposure to the identified reference media item, wherein the output is flagged as having reduced reliability.

10. The method of claim 7, wherein the indication as to whether the client device is in the physical possession of a person is provided based on output of at least one sensor associated with the client device.

11. The method of claim 10, wherein the at least one sensor detects at least one selected from the group consisting of:

vibration of the client device;

key presses on the client device;

temperature of the client device; and

movement of the client device.

12. A system for detecting user exposure to media items, comprising:

a server, for receiving a plurality of reference media items from at least one media receiver;

at least one stream collection server, for, receiving, from at least one client device;

a representation of at least one target media item from at least one client device;
