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.
