Methods and apparatus for metering portable media players
View Patent ↗Example methods, apparatus, and articles of manufacture to collect metering information associated with media presented by portable and computer media presentation devices are disclosed. A disclosed example method accesses a first data structure including metering information generated by at least one of first media presentation software executed by a personal computer or second media presentation software executed by a portable media presentation device. The metering information is associated with media presented by at least one of the first or second media presentation software. At least some of the metering information is then extracted from the first data structure and stored in a second data structure. The at least some of the metering information is then communicated from the second data structure to a data collection facility.
1. A method of monitoring media presented by a portable media presentation device, comprising:
retrieving, by executing an instruction with a processor, a frame tag code from a corresponding frame of the media, the frame tag code associated with the corresponding frame of the media presented by the portable media presentation device, the frame tag code including a frame tag code value that indicates a number of times the frame of the media has been presented via the portable media presentation device;
after the corresponding frame of the media has been presented, incrementing, by executing an instruction with the processor, the frame tag code value when a playback-time of the media corresponds to a frame tag code time offset value; and
storing, by executing an instruction with the processor, the frame tag code, with the incremented frame tag code value, in the corresponding frame of the media.
2. The method as defined in claim 1 , wherein the frame is at least one of an audio frame or a video frame.
3. The method as defined in claim 1 , wherein the media is stored separate from the frame tag code.
4. The method as defined in claim 1 , further including storing, with the processor, the frame tag code in a data structure in association with identification information indicative of at least one of a user of the portable media presentation device, the portable media presentation device, or the media.
5. The method as defined in claim 1 , further including:
prior to monitoring the media presented by the portable media presentation device, retrieving a plurality of frame tag codes associated with the media; and
storing the plurality of frame tag codes in a database.
6. The method as defined in claim 1 , further including communicating the frame tag code to one of a personal computer or a data collection facility.
7. A system to monitor media presented by a portable media presentation device, comprising:
a data extractor to retrieve a frame tag code from a frame of the media, the frame tag code associated with a corresponding frame of the media presented by the portable media presentation device, the frame tag code including a frame tag code value that indicates a number of times the frame of the media has been presented via the portable media presentation device;
a code handler to increment the frame tag code value when a playback-time of the media corresponds to a frame tag code time offset value; and
a tag code handler to, after the code handler increments the frame tag code value, store the frame tag code in the corresponding frame of the media, at least one of the data extractor or the code handler including a processor executing an instruction.
8. The system as defined in claim 7 , wherein the frame is at least one of an audio frame or a video frame.
9. The system as defined in claim 7 , wherein the media is stored separate from the frame tag code.
10. The system as defined in claim 7 , further including a second data interface to store the frame tag code in a data structure in association with identification information indicative of at least one of a user of the portable media presentation device, the portable media presentation device, or the media.
11. The system as defined in claim 7 , wherein the data extractor is to:
retrieve a plurality of frame tag codes associated with the media; and
store the plurality of frame tag codes in a database.
12. The system as defined in claim 7 , further including a second data interface to communicate the frame tag code to one of a personal computer or a data collection facility.
13. A machine readable storage device comprising instructions that, when executed, cause a processor to at least:
retrieve a frame tag code from a frame of media, the frame tag code associated with a corresponding frame of the media presented by a portable media presentation device, the frame tag code including a frame tag code value that indicates a number of times the frame of the media has been presented via the portable media presentation device;
after the corresponding frame of the media has been presented, increment the frame tag code value when a playback-time of the media corresponds to a frame tag code time offset value; and
store the frame tag code, with the incremented frame tag code value, in the corresponding frame of the media.
14. The machine readable storage device as defined in claim 13 , wherein the frame is at least one of an audio frame or a video frame.
15. The machine readable storage device as defined in claim 13 , wherein the instructions cause the processor to store the frame tag code in a data structure in association with identification information indicative of at least one of a user of the portable media presentation device, the portable media presentation device, or the media.
16. The machine readable storage device as defined in claim 13 , wherein the instructions cause the processor to:
retrieve a plurality of frame tag codes associated with the media; and
store the plurality of frame tag codes in a database.
17. The machine readable storage device as defined in claim 13 , wherein the instructions cause the processor to communicate the frame tag code to one of a personal computer or a data collection facility.
18. The method as defined in claim 1 , further including storing, by executing an instruction with the processor, the frame tag code, including the incremented frame tag code value, in a database.
19. The system as defined in claim 7 , further including a first data interface to, after the corresponding frame of the media has been presented, store the frame tag code, including the incremented frame tag code value, in a database.
20. The machine readable storage device as defined in claim 13 , wherein the instructions cause the processor to store the frame tag code, including the incremented frame tag code value, in a database.
