Abstract

Example methods disclosed herein include associating a first data pattern obtained from a first sequence of watermarks detected by a first media monitor at a first time with a first transmission of first media when the first sequence of watermarks include a first identifier associated with the first media. Disclosed example methods also include associating a second data pattern obtained from a second sequence of watermarks detected by the first media monitor at a second time with a second transmission of the first media when the second sequence of watermarks include the first identifier associated with the first media. Disclosed example methods further include comparing a third data pattern obtained from a third sequence of watermarks detected by a second media monitor with the first and second data patterns to determine whether the second media monitor monitored the first transmission or the second transmission of the first media.

Claims1

Dependent claims

A media monitoring method comprising:

associating, with the processor, a first data pattern obtained from a first sequence of watermarks detected by a first media monitor at a first time with a first transmission of first media when respective watermarks in the first sequence of watermarks include a first identifier associated with the first media, the first transmission being associated with the first time;
associating, with the processor, a second data pattern obtained from a second sequence of watermarks detected by the first media monitor at a second time with a second transmission of the first media when respective watermarks in the second sequence of watermarks include the first identifier associated with the first media, the second transmission being associated with the second time;
and
comparing, with the processor, a third data pattern obtained from a third sequence of watermarks detected by a second media monitor with the first data pattern and with the second data pattern to determine whether the second media monitor monitored the first transmission of the first media or the second transmission of the first media.
