1. A method implemented by an encoder, the method comprising:
generating a bitstream comprising a sequence parameter set (SPS) and one or more sub-pictures partitioned from a picture such that a first sub-picture includes more than one slice and includes an incomplete coding tree unit (CTU) when the first sub-picture includes a right boundary that coincides with the right boundary of the picture, wherein the SPS comprises a sub-picture identifier (ID) for each of the one or more sub-pictures, and a sub-picture size and a sub-picture location for the one or more sub-pictures; and
transmitting the bitstream toward a decoder.
