ABSTRACT:
There is disclosed an apparatus for detecting program highlights in a video program. The apparatus comprises: 1) a keyword detection circuit for detecting a location of a selected keyword in an audio track of the video program; and 2) an audio signal energy level detection circuit for determining an audio signal energy level of the audio track proximate the detected location of the selected keyword and comparing the audio signal energy level to a predetermined threshold. The audio signal energy level detection circuit, in response to a determination that the audio signal energy level exceeds the predetermined threshold, identifies the detected location of the selected keyword as a program highlight.
