Abstract

Methods and apparatus for pre-scaling media content to facilitate audience measurement are disclosed. An example method includes encoding a media content sample in accordance with a first encoding configuration and playing the encoded sample. The example method also includes attempting to detect the codes in the sample, and computing a ratio between the codes encoded in the sample and the codes detected when the sample is played.

First claim

What is claimed is:

1. An apparatus to encode media, the apparatus comprising:
memory;
computer readable instructions; and
at least one processor to execute the computer readable instructions to at least:
encode a media sample with an original number of codes to create an encoded media sample;
cause presentation of the encoded media sample in a first ambient environment provided by a media tester, the first ambient environment having a first ambient configuration value;
identify a detected number of codes extracted from the encoded media sample presented in the first ambient environment;
generate a scaling factor for the media sample based on the first ambient configuration value and a ratio of (a) the original number of codes to (b) the detected number of codes; and
determine a threshold value based on the scaling factor, the threshold value to correspond to a portion of the original number of codes required to be detected to establish detection of an advertisement associated with the encoded media sample when the encoded media sample is subsequently presented via a device other than the media tester in a second ambient environment, the second ambient environment having a characteristic corresponding to the first ambient configuration value.

2. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to embed the ratio in the media sample as metadata.

3. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to identify a code type to be embedded in the media sample.

4. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to establish an encoding volume for the original number of codes.

5. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to cause ambient noise to be presented during the presentation of the encoded media sample in the first ambient environment.

6. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to establish a volume level at which the encoded media sample is to be presented.

7. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to:
associate the scaling factor with the media sample; and
store the scaling factor in a database.

8. The apparatus as defined in claim 1 , wherein the at least one processor is to execute the computer readable instructions to assign the media sample to a first detection category based on the scaling factor, the first detection category to be assigned relative to a second detection category associated with a different scaling factor than the first detection category.

9. The apparatus as defined in claim 1 , wherein the encoded media sample includes the advertisement.

10. The apparatus as defined in claim 1 , wherein the encoded media sample includes a first encoding configuration having a first playback volume parameter, a first encoding volume parameter, and a first ambient noise volume parameter.

11. The apparatus as defined in claim 1 , wherein respective ones of the codes are audio watermarks.

12. An apparatus to encode media, the apparatus comprising:
means for encoding a media sample with an original number of codes to create an encoded media sample;
means for playing the encoded media sample in a first ambient environment provided by a media tester, the first ambient environment having a first ambient configuration value;
means for detecting a detected number of codes extracted from the encoded media sample played in the first ambient environment; and
a correlator to:
generate a scaling factor for the media sample based on the first ambient configuration value and a ratio of (a) the original number of codes to (b) the detected number of codes; and
determine a threshold value based on the scaling factor, the threshold value to correspond to a portion of the original number of codes required to be detected to establish detection of an advertisement associated with the encoded media sample when the encoded media sample is subsequently played via a device other than the media tester in a second ambient environment, the second ambient environment having a characteristic corresponding to the first ambient configuration value.

13. The apparatus as defined in claim 12 , further including means for identifying a code type to be embedded in the media sample by the means for encoding.

14. The apparatus as defined in claim 12 , further including means for establishing an encoding volume for the original number of codes encoded in the media sample.

15. The apparatus as defined in claim 12 , further including means for playing ambient noise while the encoded media sample is being played by the means for playing the encoded media sample.

16. The apparatus as defined in claim 12 , further including means for establishing a volume level at which the means for playing the encoded media sample is to play the encoded media sample.

17. A non-transitory computer readable medium comprising computer readable instructions that, when executed, cause one or more processors to at least:
encode a media sample with an original number of codes to create an encoded media sample;
cause presentation of the encoded media sample in a first ambient environment provided by a media tester, the first ambient environment having a first ambient configuration value;
identify a detected number of codes extracted from the encoded media sample presented in the first ambient environment;
generate a scaling factor for the media sample based on the first ambient configuration value and a ratio of (a) the original number of codes to (b) the detected number of codes; and
determine a threshold value based on the scaling factor, the threshold value to correspond to a portion of the original number of codes required to be detected to establish detection of an advertisement associated with the encoded media sample when the encoded media sample is subsequently presented via a device other than the media tester in a second ambient environment, the second ambient environment having a characteristic corresponding to the first ambient configuration value.

18. The non-transitory computer readable medium of claim 17 , wherein the instructions, when executed cause the one or more processors to embed the ratio in the media sample as metadata.

19. The non-transitory computer readable medium of claim 17 , wherein the instructions, when executed cause the one or more processors to identify a code type to be embedded in the media sample.

20. The non-transitory computer readable medium of claim 17 , wherein the instructions, when executed cause the one or more processors to establish an encoding volume for the original number of codes.

21. The non-transitory computer readable medium of claim 17 , wherein the instructions, when executed cause the one or more processors to cause ambient noise to be presented during the presentation of the encoded media sample in the first ambient environment.

22. The non-transitory computer readable medium of claim 17 , wherein the instructions, when executed cause the one or more processors to establish a volume level at which the encoded media sample is to be presented.
