Abstract

A method for the production of picture sequences for a fast search operation in a film play-back device (10, 40) is proposed. In this case, the video data of the individual pictures of the film are stored in digitally coded form in a storage unit (11, 41). The method is distinguished by the fact that 1. the video data of the pictures are read out from the storage unit (11, 41) at an increased speed, that 2. the read-out video data are decoded at an increased speed in a decoder (18, 43), that 3. only the video data of specific individual pictures are selected from the decoded video data and are fed to an encoder (21, 45) which operates at a regular speed.
