We extend our sports video browsing framework for personal video recorders, such as DVD recorders, blu-ray disc recorders and/or hard disc recorders, to other genres. We reduce the computational complexity by reducing the number of audio classes to a small but useful set that is useful for both sports video and music video, as well as by reducing the complexity of the Gaussian mixture models. Our extension to music video content consists of detecting music/song periods by compensating for false alarms. Our results indicate that our enhanced audio-only summarization maintains the sports video performance and works well with music video content. We can therefore integrate the enhancement into our product while in fact reducing the computational complexity.
