Abstract
An image sequence captured at a first image rate is encoded as an encoded image sequence at a second image rate with information in the encoded image sequence indicative of images that are repeated when decoded. To assist in editing a video program using the encoded image sequence, the information in the encoded image sequence indicative of images that are repeated when decoded may be cleared. Further, image index information for the encoded image sequence may be generated. This image index information is used to map a temporal position of an image in a decoded image sequence to a position of corresponding data in the encoded image sequence. Temporal positions used with the image index information correspond to the first image rate.
