    • 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.
    • 根据本发明的实施例,一种将次要内容插入到媒体流中的方法包括:在处理器处将具有多个帧的媒体流划分成多个镜头。 所述方法还包括将来自所述多个拍摄的连续拍摄分组成多个场景。 生成用于引入次要内容的插入点的第一列表。 第一列表的插入点是多个场景中的连续场景之间的边界。 在第一列表中的插入点处生成媒体流的平均插入点显着性。 然后生成插入点的第二列表。 第二列表中的插入点被布置成使平均插入点显着性的功能和第二列表中的每个插入点之间的距离与第二列表中的其他插入点最大化。
