摘要： In accordance with an embodiment of the present invention, a method for inserting secondary content into a media stream includes dividing the media stream having a plurality of frames into a plurality of shots at a processor. The method further includes grouping consecutive shots from the plurality of shots into a plurality of scenes. A first list of insertion points is generated for introducing the secondary content. The insertion points of the first list are boundaries between consecutive scenes in the plurality of scenes. An average insertion point saliency of the media stream is generated at the insertion points in the first list. A second list of insertion points is then generated. The insertion points in the second list are arranged to maximize a function of the average insertion point saliency and a distance between each insertion point in the second list with other insertion points in the second list.
