ABSTRACT:
Encoded pictures comprise one or more independently decodable frames, reference frames, and predicted frames. In the method an arrangement step is performed for arranging the pictures in an encoding order, and information on the presentation order is defined for the encoded pictures. Further in the method, a transmission step is performed for transmitting said encoded pictures to a decoder, a decoding step for decoding the encoded pictures for forming decoded pictures, and rearranging step for arranging the decoded pictures in presentation order. An expected increment value of the presentation order per picture is defined, and a parameter indicative of the difference between the expected increment value and the real increment value is calculated. The calculated parameter is VLC coded, and the VLC coded parameter is transmitted, wherein the VLC coded parameter is used in the decoder for arranging the decoded pictures in correct presentation order.
