Abstract

A device (1800) for processing an input data stream comprising a sequence of input frames, wherein the device comprises a processing unit (1802) for generating an output data stream as a trick-play stream comprising a sequence of output frames based on the input data stream and based on a predetermined replication rate, and a timing unit (1803) for assigning timing information to the output frames, said timing information pointing from an output frame to be reproduced for the first time to a subsequent one of the output frames which is to be reproduced for the first time.
