Patent ID: 7584428

Claim:
An apparatus for detecting highlights of a media stream, the apparatus comprising: a video processing module for determining a video threshold value by referring to motion vectors in the media stream; an audio processing module for determining at least one audio threshold value by referring to volume energy in the media stream; a shot change detector, electrically connected to the video processing module and the audio processing module, for deciding a shot change to inform the video processing module and the audio processing module; and a post processor, electrically connected to the video processing module and the audio processing module, for determining the video highlights according to video parameters and the video threshold value, and the audio highlights according to audio parameters and the audio threshold value, and then deciding the highlights of the media stream according to the video highlights and the audio highlights; wherein each of the video parameters is a sum of motion vectors, and the post processor compares the sum associated with a current frame with the video threshold value; if the sum is greater than the video threshold value, the post processor decides the current frame as a video highlight; and if the sum is not greater than the video threshold value, the post processor does not decide the current frame as the video highlight; wherein when a video parameter corresponding to a first frame is greater than the video threshold value, the post processor decides the first frame as a video highlight; and when an audio parameter corresponding to a second frame is greater than the audio threshold value, the post processor decides the second frame as an audio highlight.
