1. A video decoder for decoding a video of pictures from a data stream, the data stream having the video encoded thereinto in a manner according to which sub-pictures into which the pictures are spatially sub-divided are encoded independently from each other, the video decoder configured to:
decode from the data stream, for each sub-picture of each picture of a set of one or more pictures of the video, a sub-picture related information which, when assuming a first state, identifies the respective sub-picture as being coded in a random access point manner and, when assuming a second state, identifies the respective sub-picture as not being coded in the random access point manner; and
decode from the data stream, for the set of one or more pictures, a random access point signaling granularity indication which;
when assuming a first granularity, indicates that, for each picture of the set of one or more pictures, the sub-picture related information assumes a common state for all of the sub-pictures of the respective picture, and
when assuming a second granularity, indicates that, for each picture of the set of one or more pictures, the sub-picture related information is allowed to assume different states for the sub-pictures of the respective picture.
