摘要

The invention relates to a method and apparatus for fast retrieval of frames of a video stream or other data fragments like sound for fast, non-real-time trickplay navigation through the content. According to the invention, a group of multiple fragments of data is identified for rendering; the pick-up unit is moved to a location on the medium where the identified group of multiple fragments of data is stored; a fragment of data is selected from the group of multiple fragments of data, the fragment of data being fastest retrievable by the pick-up unit; and the selected fragment of data is retrieved for rendering.
