Detection of music segment boundaries using audio-visual features for a personal video recorder

We have extended our sports video browsing framework for personal video recorders, such as recordable-DVD recorders, blu-ray disc recorders and/or hard disc recorders, to music segment detection. Our extension to Japanese broadcast music video programs consists of detecting audio segment boundaries such as conversations with guests followed by music/song etc. Our proposed system first identifies the music/song scenes using audio analysis, and then adjusts the start/end position by detecting video shot changes, so as to achieve accurate detection of the music segment thus enabling rapid browsing. Our preliminary results indicate that our audio-only summarization with scene change support works well for music video content. We can therefore integrate the enhancement into our product at a low computational cost.
