Abstract

A video decoder for decoding an encoded video signal including encoded picture data and indication data of a picture of a video to reconstruct the picture of the video is provided. The video decoder includes an interface configured for receiving the encoded video signal, and a data decoder configured for reconstructing the picture of the video by decoding the encoded picture data using the indication data. The picture is partitioned into a plurality of coding areas. One or more coding areas of the plurality of coding areas include two or more coding tree units of the plurality of coding tree units, wherein each coding area of the one or more coding areas which includes two or more coding tree units exhibits a coding order for the two or more coding tree units of the coding area.
