Methods and apparatus to monitor a media presentation
Methods, apparatus, systems and articles of manufacture to monitor a media presentation are disclosed. An example method includes in response to receipt of a media identifier, extracting, by executing an instruction with a processor, a timestamp from the received media identifier. A time of receipt of the media identifier is determined. A difference between the time of receipt of the media identifier and the timestamp from the received media identifier is determined. A time shifted viewing code is calculated based on the difference The time shifted viewing code is transmitted to a media monitor that transmitted the media identifier, the time shifted viewing code to be reported when the media monitor reports monitoring information.

6. The apparatus of claim 1 , wherein the media identifier includes the timestamp and a station identifier.
7. An apparatus comprising:
means for gathering to:
gather metadata associated with a media presentation on a media device;
gather a media identifier corresponding to the media presentation;
means for causing transmission of a request for a time shifted viewing code from a server of a central facility, the request including the media identifier, the time shifted viewing code determined based on a time of receipt of the request for the time shifted viewing code and a timestamp of the media presentation;
means for constructing a segment code, the segment code including: a segment pattern having indicia corresponding to first periods of media presented on the media device and second periods of the media not presented on the media device and (ii) a segment number determined by dividing a difference between a first time corresponding to the media presentation on the media device and a second time corresponding to a beginning of a media presentation day; and
means for transmitting a monitoring message to a database proprietor, the monitoring message including the time shifted viewing code, the segment code, the metadata and the media identifier, the monitoring message enabling the database proprietor to provide demographic information associated with a user of the media device to the central facility, the database proprietor separate from the central facility, the database proprietor to maintain user records including the demographic information.
8. The apparatus of claim 7 , wherein the metadata includes at least one of a platform identifier, a device type information, an operating system (OS) version information, a placement identifier, or a country code.
9. The apparatus of claim 7 , wherein the means for gathering is to store the metadata and the media identifier in a buffer, and wherein the means for constructing is to:
analyze the buffer to determine whether a media segment is complete;
after determining the media segment is complete:
construct the monitoring message, the monitoring message including information associated with the media segment; and
clear the buffer.
10. The apparatus of claim 9 , wherein the means for constructing is to determine whether the media segment is complete based on a presence of a quantity of media identifiers corresponding to a segment length, the quantity of media identifiers including the media identifier.
11. The apparatus of claim 10 , further including means for accessing configuration parameters from the central facility, the configuration parameters including the segment length.
12. The apparatus of claim 7 , wherein the media identifier includes the timestamp and a station identifier.
13. A non-transitory computer readable medium comprising instructions, which when executed, cause a processor to at least:
gather metadata associated with a media presentation on a media device;
gather a media identifier corresponding to the media presentation;
cause transmission of a request for a time shifted viewing code from a server of a central facility, the request including the media identifier, the time shifted viewing code determined based on a time of receipt of the request for the time shifted viewing code and a timestamp of the media presentation;
construct a segment code, the segment code including: (i) a segment pattern having indicia corresponding to first periods of media presented on the media device and second periods of the media not presented on the media device and (ii) a segment number determined by dividing a difference between a first time corresponding to the media presentation on the media device and a second time corresponding to a beginning of a media presentation day; and
cause transmission of a monitoring message to a database proprietor, the monitoring message including the time shifted viewing code, the segment code, the metadata and the media identifier, the monitoring message enabling the database proprietor to provide demographic information associated with a user of the media device to the central facility, the database proprietor separate from the central facility, the database proprietor to maintain user records including the demographic information.
14. The non-transitory computer readable medium of claim 13 , wherein the metadata includes at least one of a platform identifier, a device type information, an operating system (OS) version information, a placement identifier, or a country code.
15. The non-transitory computer readable medium of claim 13 , wherein the instructions further cause the processor to:
