We present a technique for rapidly generating highlights of sports videos using temporal patterns of motion activity extracted in the compressed domain. The basic hypothesis of this work is that temporal patterns of motion activity are related with the grammar of the sports video. We present experimental verification of this hypothesis. By using very simple rules depending on the type of sport, we are thus able to provide highlights by skipping over the uninteresting parts of the video and identifying interesting events characterized, for instance, by falling edge or raising edge in the activity domain. Moreover the compressed domain extraction of motion activity intensity is much simpler than the color based summarization calculations. Other compressed domain features or more complex rules can be used to further improve the accuracy.
