Abstract The invention proposes a method for reverse playback of a digital data stream representing video information. The information is stored in an Intra picture coded format followed by several Non-Intra coded pictures. For reverse playback n sectors are jumped back from the actual scanning position. The location of the n sectors is read in forward direction. A sector location list is created. The sector location list is resorted to a reverse order. The position of sector stream is parsed according to the sector location list in order to find appropriate position of start codes of the video information. Digital data stream from position of start codes is delivered to a following processing unit.
