Abstract
A video processing device includes a background audio change detector that detects background audio changes in audio data corresponding to particular video data. The video processing device detects semantically meaningful video scenes using detected background audio changes and delimits segments of the video data.
Claims36
A video processing device, comprising:
- a background audio change detecting means for detecting background audio changes in video data;
- and
- a memory communicating with said background audio change detecting means and storing said video data and audio data corresponding to said video data;
- wherein said background audio change detecting means detects a background audio change in said audio data and detects semantically meaningful video scenes using detected background audio changes.

A video processing device, comprising:
- a processor;
- a background audio change detector communicating with said processor;
- and
- a memory communicating with said processor, said memory storing video data and audio data corresponding to said video data;
- wherein said background audio change detector detects a background audio change in said audio data and wherein said processor detects semantically meaningful video scenes using detected background audio changes and delimits segments of said video data.
2 more elements
A method of segmenting video data, comprising the steps of:
- detecting background audio changes in background audio data corresponding to said video data;
- detecting semantically meaningful video scenes using detected background audio changes.
A method of segmenting video data, comprising the steps of:
- determining whether audio data corresponding to said video data is background audio;
- sampling said audio data if said audio data is said background audio;
- detecting background audio changes in said audio data;
- detecting video shot changes in said video data;
- detecting semantically meaningful video scenes using detected background audio changes that occur in conjunction with detected video shot changes;
- and
- delimiting video segments corresponding to said semantically meaningful video scenes.
