1. A method of decoding a received set of encoded data representing information that has been compressed, the encoded data set comprising a plurality of subsets, each subset representing a region of the information that has been compressed, the method comprising:
receiving the encoded data set;
retrieving signalled size dimensions of the information that has been compressed;
based on the signalled size dimensions, identifying a maximum amount of subsets expected in the data set, the subsets comprising a predetermined maximum amount of encoded data elements, and identifying an expected amount of data elements to be represented by each subset;
decoding the encoded data set to derive a set of data elements based on the expected amount of data elements represented by each subset; and,
reconstructing the information that has been compressed using the derived set of data elements.
