A method for selecting a subsequence of video frames (72-84) from a sequence of video frames (70) comprising defining a distance function between video frames (72-84) in the sequence of video frames (70). An optimization criterion is defined to express a feature of a plurality of subsequences of video frames (72-84) selected from the sequence of video frames (70). A method is disclosed for displaying key frames for browsing and streaming.
