1. A video decoder for receiving a video data stream having a video stored therein,
wherein the video decoder is configured to decode the video from the video data stream,
wherein the video data stream comprises scalable nested supplemental enhancement information messages,
wherein the scalable nested supplemental enhancement information messages comprise a plurality of syntax elements,
wherein each syntax element of one or more syntax elements of the plurality of syntax elements is defined to have a same length in every one of the scalable nested supplemental enhancement information messages of the video data stream or of a portion of the video data stream,
wherein the video decoder is configured to decode the video depending on the one or more syntax elements of the plurality of syntax elements.
