Systems, methods, and apparatus to identify linear and non-linear media presentations

1. An apparatus to automatically determine whether a media presentation is a linear media presentation or a non-linear media presentation, the apparatus comprising:

one or more processors; and

memory including computer readable instructions which, when executed, cause the one or more processors to at least:

obtain at least one of an audio fingerprint or a watermark code generated by a media monitoring device electronically monitoring the media presentation of first media;

identify first media identifiers of the first media from the at least one of the audio fingerprint or the watermark code by comparing the at least one of the audio fingerprint or the watermark code to a reference audio fingerprint or a reference watermark code;

generate a media presentation log for the media presentation of the first media, the media presentation log including first media identifiers of the first media and first times at which the first media was presented;

generate a reference log including second media identifiers of second media and second times at which the second media was presented as a linear media presentation;

compare the media presentation log to the reference log to determine a duration associated with matches between ones of the first media identifiers and ones of the second media identifiers, the matches between the ones of the first media identifiers and the ones of the second media identifiers being in a same order in the media presentation log and the reference log, the duration based on at least one of the first times or the second times; and

classify the media presentation of the first media as a linear media presentation when the duration satisfies a threshold.

2. The apparatus as defined in claim 1 , wherein the computer readable instructions, when executed, further cause the one or more processors to classify the media presentation of the first media as a non-linear media presentation when the duration does not satisfy the threshold.

3. The apparatus as defined in claim 1 , wherein the first media includes first program media and first non-program media, and the second media includes second program media and second non-program media.

4. The apparatus as defined in claim 1 , wherein the media presentation log includes an identification of a first portion of the first media as program media and a second portion of the first media as non-program media.

5. The apparatus as defined in claim 4 , wherein the media presentation log includes the identification of the first portion of the first media as program media in response to a code present in the first portion of the first media matching a reference code associated with reference program media.

6. The apparatus as defined in claim 4 , wherein the media presentation log includes the identification of the first portion of the first media as program media in response to a signature generated based on the first portion of the first media matching a reference signature associated with reference program media.

7. The apparatus as defined in claim 4 , wherein the media presentation log includes the identification of the second portion of the first media as non-program media in response to presentation of the second portion of the first media following a blank frame present in the first media.

8. The apparatus as defined in claim 4 , wherein the media presentation log includes the identification of the second portion of the first media as non-program media in response to presentation of the second portion of the first media following a cue tone present in the first media.

9. The apparatus as defined in claim 4 , wherein the media presentation log includes the identification of the first portion of the first media as program media in response to detection of a logo in the first portion of the first media.

10. The apparatus as defined in claim 1 , wherein the audio fingerprint is based on an audio characteristic of the first media electronically measured at discrete times by the media monitoring device.

11. An apparatus to automatically determine whether a media presentation is a linear media presentation or a non-linear media presentation, the apparatus comprising:

one or more processors; and

memory including computer readable instructions which, when executed, cause the one or more processors to at least:

obtain at least one of an audio fingerprint or a watermark code generated by a media monitoring device electronically monitoring the media presentation of first media;

identify first media identifiers of the first media from the at least one of the audio fingerprint or the watermark code by comparing the at least one of the audio fingerprint or the watermark code to a reference audio fingerprint or a reference watermark code;

generate a media presentation log for the media presentation of the first media, the media presentation log including first media identifiers of the first media and first times at which the first media was presented;

generate a reference log including second media identifiers of second media and second times at which the second media was presented as a linear media presentation;

compare the media presentation log to the reference log to determine a number of matches between ones of the first media identifiers and ones of the second media identifiers, the matches between the ones of the first media identifiers and the ones of the second media identifiers being in a same order in the media presentation log and the reference log; and

classify the media presentation of the first media as a linear media presentation when the number of matches satisfies a threshold.

12. The apparatus as defined in claim 11 , wherein the computer readable instructions, when executed, further cause the one or more processors to classify the media presentation of the first media as a non-linear media presentation when the number of matches does not satisfy the threshold.

13. The apparatus as defined in claim 11 , wherein the first media includes first program media and first non-program media, and the second media includes second program media and second non-program media.

14. The apparatus as defined in claim 11 , wherein the media presentation log includes an identification of a first portion of the first media as program media and a second portion of the first media as non-program media.

15. The apparatus as defined in claim 14 , wherein the media presentation log includes the identification of the first portion of the first media as program media in response to a code present in the first portion of the first media matching a reference code associated with reference program media.

16. The apparatus as defined in claim 14 , wherein the media presentation log includes the identification of the first portion of the first media as program media in response to a signature generated based on the first portion of the first media matching a reference signature associated with reference program media.

17. The apparatus as defined in claim 14 , wherein the media presentation log includes the identification of the second portion of the first media as non-program media in response to presentation of the second portion of the first media following a blank frame present in the first media.

18. The apparatus defined in claim 14 , wherein the media presentation log includes the identification of the second portion of the first media as non-program media in response to presentation of the second portion of the first media following a cue tone present in the first media.

19. The apparatus as defined in claim 14 , wherein the media presentation log includes the identification of the first portion of the first media as program media in response to detection of a logo in the first portion of the first media.

20. The apparatus as defined in claim 11 , wherein the audio fingerprint is based on an audio characteristic of the first media electronically measured at discrete times by the media monitoring device.
