1. A method of video encoding a sequence of pictures, the method being implemented in an encoding device and comprising:
obtaining an intra prediction picture comprising at least two sub-units, wherein the at least two sub-units of the intra prediction picture are video coding layer network abstraction layer (VCL NAL) units;
obtaining a first encoded other picture, wherein the first encoded other picture is an inter-coded random access picture, wherein the intra prediction picture and the inter-coded random access picture have a same Picture Order Count (POC) value;
obtaining one or more encoded other pictures different from the intra prediction picture and the first encoded other picture; and
distributing the at least two sub-units of the intra prediction picture over one or more sub-units of the one or more encoded other pictures and/or over one or more sub-units of the first encoded other picture.
