Systems and methods to pre-scale media content to facilitate audience measurement
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.
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.
