Abstract
A method for high speed playback of digital video data (e.g. D1 or D2 data) in which, at lower speeds, the frames of data to be played back are made of a mixture of consecutive frames of data. The frames of data are mixed by averaging the pixel values over consecutive frames to make up the output frames. For high speed shuttle operation, non-consecutive frames are averaged on a pixel by pixel basis to create shuttle frames. In order to improve the appearance of the output, consecutive shuttle frames contain a common original frame so that a component of the original data spans two output frames.
