1. A method to detect a commercial transition associated with a media presentation, the method comprising:
- comparing, by executing an instruction with a processor, an amount of audio randomness in an inter-segment audio frame to a random level threshold, the amount of audio randomness being based on a random-factor ratio; and
in response to the amount of randomness satisfying the random level threshold, indicating, by executing an instruction with the processor, the inter-segment audio frame is associated with the commercial transition.

Abstract
Methods and apparatus to detect commercial advertisements associated with media presentations are disclosed. An example method includes comparing an amount of audio randomness in an inter-segment audio frame to a random level threshold, the amount of audio randomness being based on a random-factor ratio; and in response to the amount of randomness satisfying the random level threshold, indicating the inter-segment audio frame is associated with the commercial transition.

11. An apparatus to detect a commercial transition associated with a media presentation, the apparatus comprising:
-
an audio features detector to compare an amount of audio randomness in an inter-segment audio frame to a random level threshold, the amount of audio randomness being based on a random-factor ratio; and an advertisement detector to indicate, in response to the amount of audio randomness satisfying the random level threshold, the inter-segment audio frame as occurring at the commercial transition. - View Dependent Claims (12, 13, 14)

15. A non-transitory computer readable medium comprising instructions that, when executed, cause a processor to at least:
-
compare an amount of audio randomness in an inter-segment audio frame of a media presentation to a random level threshold, the amount of audio randomness being based on a random-factor ratio; and in response to the amount of audio randomness satisfying the random level threshold, indicate the inter-segment audio frame is associated with the commercial transition. - View Dependent Claims (16, 17, 18, 19, 20)
