Claim 0:
1. A decoding apparatus comprising a microprocessor and memory, the memory comprising a computer program comprising instructions, which, when executed by the microprocessor, cause the decoding apparatus to:
decode, from a picture parameter set (PPS) of a video data stream, conformance cropping window parameters comprising a pps_conf_win_left_offset, a pps_conf_win_top_offset, a pps_conf_win_right_offset, and a pps_conf_win_bottom_offset;
decode, from the picture parameter set (PPS), a
pps_scaling_window_explicit_signalling_flag;
determine that the pps_scaling_window_explicit_signalling_flag has a value of false; and
based on the determination that the pps_scaling_window_explicit_signalling_flag has a value of false, perform upscaling of a region within a reference picture by using the pps_conf_win_left_offset, the pps_conf_win_top_offset, the pps_conf_win_right_offset, and the pps_conf_win_bottom_offset.
