Augmenting fast-forward and rewind for personal digital video recorders

This work describes a set of interfaces for augmenting fast-forward and rewind on consumer digital video recorders. Our method overlays a series of images sampled from the video over top of the traditional full screen accelerated playback. This sequence creates a trail that provides contextual information and highlights upcoming scene changes in the video stream. With this augmentation, consumers are more accurate at traversing to a desired location in a recorded video. This advantage is achieved by taking advantage of compressed-domain processing and adds little computational and storage overhead.
