Abstract:
1. A method to determine a time offset between a first media signature comprising a first sequence of first data pairs and a second media signature comprising a second sequence of second data pairs, the method comprising: comparing, using a processor, each first data pair in the first sequence with each second data pair in the second sequence to determine a respective time difference between each first data pair and second data pair combination; determining, using the processor, a histogram comprising a plurality of bins representative of a plurality of determined time differences, the plurality of determined time differences comprising each respective time difference determined between each first data pair and second data pair combination, each respective bin of the histogram representing a respective window of time differences and having a respective value representative of a number of the plurality of determined time differences lying within the respective window of time differences represented by the respective bin; and selecting at least one bin of the histogram to correspond to the time offset between the first signature and the second signature.
