Abstract
Methods and apparatus to detect commercial advertisements associated with media presentations are disclosed. An example apparatus to detect a commercial transition associated with a media presentation include means for comparing an amount of audio randomness in an inter-segment audio frame to a random level threshold, where the amount of audio randomness is based on a random-factor ratio. The example apparatus further includes means for indicating, in response to the amount of audio randomness satisfying the random level threshold, the inter-segment audio frame as occurring at the commercial transition.
