Classification: CPC H | IPC H

Claim 8:
9. A device for generating an encoded video bitstream, the device comprising:
at least one memory configured to store program code; and
at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
generating code configured to cause the at least one processor 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.
