1. A method comprising:
dividing a picture into a first sub-picture and a second sub-picture;
determining a first position of a non-overlapping region in the picture based on a first scan order;
determining a second position of the non-overlapping region in the first sub-picture based on the first position and based on a second scan order;
generating a first coded sub-picture by at least coding the first sub-picture based on the second position of the non-overlapping region;
generating a second coded sub-picture by at least coding the second sub-picture in parallel with the coding of the first sub-picture;
encoding the first coded sub-picture into a bit stream; and
encoding the second coded sub-picture into the bit stream sequentially with the encoding the first coded sub-picture.
