Abstract

A decoder has a first memory for storing a coded first image. The image is stored in the first memory until it has been decoded at least twice. The results of the decoding operations can be supplied to a playback device. The invention makes it possible to dispense with an output frame buffer for the decoded first image, and thus only little memory is required in the decoder.
