Claim 16:
17. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by one or more processors of a device for generating an encoded video bitstream, cause the one or more processors to:
generate the encoded video bitstream that comprises (i) a flag indicating whether a conformance window is used for a reference picture resampling and (ii) a reference picture resampling parameter,
wherein the flag indicates that the conformance window is not used for reference picture resampling,
wherein based on a determination that the conformance window is not used for the reference picture resampling and a determination that the reference picture resampling parameter is to be signaled, the reference picture resampling parameter comprises a plurality of reference region parameters to be used to calculate scaling for the reference picture resampling, the plurality of reference region parameters comprising at least a reference region left offset and a reference region top offset,
wherein a current picture is encoded using the reference picture resampling parameter comprising the plurality of reference region parameters.
