| Abstract: |
Browsing of digital video data is performed using a fast forward or fast reverse play mode. The digital video is analyzed and processed to produce a content-based variable-rate video playback sequence for fast browsing. To create the playback sequence, each shot in a video is sped-up at a relatively slow rate at the beginning of the shot by selecting many frames and then the speedup rate is increased as the shot progresses by selecting progressively fewer frames. This method and apparatus of variable-rate frame selection can be used to add and index to a video, play an original video in fast forward/backward mode or to create a new video-a fast forward playback video summary.
