Claim 18:
19. The video decoder of claim 1, wherein the pictures are spatially sub-divided into the sub-pictures in a constant over a sequence of pictures so that sub-videos are coded into sequence of pictures and in each picture of the sequence of pictures one sub-picture belongs to one of the sub-videos and wherein each sub-picture is encoded independently from sub-pictures of the pictures which belong to a different sub-video, the video decoder configured to:
decode from the data stream, for each sub-picture of each picture of the set of one or more pictures, a first POC value,
if the random access point signaling granularity indication assumes the second granularity, manage, for each sub-video, one or more inter-sub-picture POC compensation parameters which parametrize a parametrizable function which, when applied to the first POC value decoded for a sub-picture of a currently decoded picture belonging to the respective sub-video, yields a final POC value so that the final POC values of the sub-pictures of the currently decoded picture are equal to each other.
