Methods and apparatus to identify media
View Patent ↗Methods and apparatus for identifying media are described. An example method includes determining application identification information for a media presentation application executing on a media device, determining a first watermark for the application identification information from a lookup table, requesting media identification information for media from the media presentation application, determining a second watermark for the media identification information from the lookup table, inserting the first watermark in the media prior to output of the media by the media device, and inserting the second watermark in the media prior to the output of the media by the media device.
1. A method comprising:
determining application identification information for a media presentation application executing on a media device;
determining a first watermark for the application identification information from a lookup table;
requesting media identification information for media from the media presentation application;
determining a second watermark for the media identification information from the lookup table;
inserting the first watermark in the media prior to output of the media by the media device; and
inserting the second watermark in the media prior to the output of the media by the media device.
2. A method as defined in claim 1 , wherein the first watermark is a final distributor watermark and the second watermark is a program content watermark.
3. A method as defined in claim 1 , wherein a time in content field of the second watermark indicates the media identification information.
4. A method as defined in claim 3 , wherein a source identifier field of the second watermark indicates a platform of the media.
5. A method as defined in claim 1 , wherein a time in content field of the first watermark indicates the application identification information.
6. A method as defined in claim 5 , wherein the first watermark is inserted in the media substantially immediately after the second watermark.
7. A method as defined in claim 1 , further comprising alternately inserting copies of the second watermark and copies of the first watermark.
8. A method as defined in claim 1 , wherein the media identification information is a manufacturer identification number.
9. A method as defined in claim 1 , wherein the media identification information is embedded in the media.
10. A method as defined in claim 1 , wherein at least one of the first watermark and the second watermark is inserted in audio of the media.
11. A method as defined in claim 1 , further comprising:
detecting authorization for monitoring at the media presentation device; and
issuing a rebate in response to detecting the authorization.
12. An apparatus comprising:
a device interface to determine application identification information for a media presentation application executing on a media device;
an application interface to request media identification information for media from the media presentation application;
a data compiler to determine information for a first watermark for the application identification information from a lookup table and information for a second watermark for the media identification information from the lookup table; and
a watermark generator to generate the first watermark and the second watermark, insert the first watermark in the media prior to output of the media by the media device, and insert the second watermark in the media prior to the output of the media by the media device.
13. An apparatus as defined in claim 12 , wherein the first watermark is a final distributor watermark and the second watermark is a program content watermark.
14. An apparatus as defined in claim 12 , wherein a time in content field of the second watermark indicates the media identification information.
15. An apparatus as defined in claim 14 , wherein a source identifier field of the second watermark indicates a platform of the media.
16. An apparatus as defined in claim 12 , wherein a time in content field of the first watermark indicates the application identification information.
17. An apparatus as defined in claim 12 , wherein the first watermark is inserted in the media substantially immediately after the second watermark.
18. An apparatus as defined in claim 12 , wherein the watermark generator is to alternately insert copies of the second watermark and copies of the first watermark.
19. A tangible computer readable storage medium comprising instructions that, when executed cause a machine to at least:
determine application identification information for a media presentation application executing on a media device;
determine a first watermark for the application identification information from a lookup table;
request media identification information for media from the media presentation application;
determine a second watermark for the media identification information from the lookup table;
insert the first watermark in the media prior to output of the media by the media device; and
insert the second watermark in the media prior to the output of the media by the media device.
20. A tangible computer readable storage medium as defined in claim 19 , wherein the first watermark is a final distributor watermark and the second watermark is a program content watermark.
21. A tangible computer readable storage medium as defined in claim 19 , wherein a time in content field of the second watermark indicates the media identification information.
22. A tangible computer readable storage medium as defined in claim 21 , wherein a source identifier field of the second watermark indicates a platform of the media.
23. A tangible computer readable storage medium as defined in claim 19 , wherein a time in content field of the first watermark indicates the application identification information.
