Methods and apparatus to measure exposure to streaming media

1. An apparatus to measure exposure to streaming media, the apparatus comprising:

means for retrieving metadata associated with media presented at a client device, the metadata located in an ID3 tag, the means for retrieving to extract data from a first field of the metadata;

means for determining a location to transmit the metadata, the location determined based on the data from the first field of the metadata; and

means for communicating to transmit a request to the location, the request including a media identifier from a second field of the metadata and user-identifying data, the user-identifying data being accessible at the location, the second field of the metadata separate from the first field of the metadata, the media identifier identifying the streaming media.

2. The apparatus as described in claim 1 , further including means for presenting the media at the client device.

3. The apparatus as described in claim 2 , further including means for monitoring for an event triggered by the means for presenting, the means for retrieving to retrieve the metadata in response to detection of the event.

4. The apparatus as described in claim 3 , wherein the event is a media presentation event.

5. The apparatus as described in claim 1 , further including means for converting the metadata in the ID3 tag into a payload of the request.

6. The apparatus as described in claim 1 , further including means for storing the user-identifying data.

7. The apparatus as described in claim 6 , wherein the user-identifying data is cookie data.

8. An apparatus to measure exposure to streaming media, the apparatus comprising:

means for retrieving metadata associated with streaming media presented at a client device, the metadata located in an ID3 tag, the means for retrieving to extract data from a first field of the metadata;

means for determining a first internet domain to transmit the metadata, the first internet domain determined based on the data from the first field of the metadata; and

means for communicating a first request to the first internet domain, the first request including a media identifier from a second field of the metadata and user-identifying data, the user-identifying data being accessible at the first internet domain, the second field of the metadata separate from the first field of the metadata, the media identifier identifying the streaming media, the means for communicating to receive a redirection message from the first internet domain, the means for communicating to send, in response to the redirection message, a second request to a second internet domain specified by the redirection message, the means for communicating to provide second user-identifying data to the second internet domain.

9. The apparatus as described in claim 8 , further including means for presenting the streaming media at the client device.

10. The apparatus as described in claim 9 , further including means for monitoring for an event triggered by the means for presenting, the means for retrieving to retrieve the metadata in response to detection of the event.

11. The apparatus as described in claim 10 , wherein the event is a media presentation event.

12. The apparatus as described in claim 8 , further including means for converting the metadata in the ID3 tag into a payload of the first request.

13. The apparatus as described in claim 8 , further including means for storing the user-identifying data.

14. The apparatus as described in claim 13 , wherein the user-identifying data is cookie data.

15. An apparatus to measure exposure to streaming media, the apparatus comprising:

means for extracting metadata associated with streaming media presented at a client device, the means for extracting to extract data from a first field of the metadata;

means for determining a first internet domain to transmit the metadata, the first internet domain determined based on the data from the first field of the metadata; and

means for communicating a first request to the first internet domain, the first request including a media identifier from a second field of the metadata and user-identifying data, the user-identifying data being accessible at the first internet domain, the second field of the metadata separate from the first field of the metadata, the media identifier identifying the streaming media, the means for communicating to receive a redirection message from the first internet domain, the means for communicating to send, in response to the redirection message, a second request to a second internet domain specified by the redirection message, the means for communicating to provide second user-identifying data to the second internet domain.

16. The apparatus as described in claim 15 , further including means for presenting the streaming media at the client device.

17. The apparatus as described in claim 16 , further including means for monitoring for an event triggered by the means for presenting, the means for extracting to retrieve the metadata in response to detection of the event.

18. The apparatus as described in claim 17 , wherein the event is a media presentation event.

19. The apparatus as described in claim 15 , further including means for converting the metadata into a payload of the first request.

20. The apparatus as described in claim 15 , further including means for storing the user-identifying data.
