7. An encoding device, comprising:
a memory containing instructions;
one or more processors coupled to the memory, the one or more processors are configured to implement the instructions to cause the encoding device to:
generate a first picture parameter set (PPS) and a second PPS each referring to a same sequence parameter set (SPS), wherein the first PPS comprises a first picture width parameter, a first picture height parameter, and a first conformance window flag, wherein the second PPS comprises a second picture width parameter, a second picture height parameter, and a second conformance window flag, wherein the first conformance window flag being equal to 1 specifies that the first PPS further comprises first conformance window parameters, wherein the second conformance window flag being equal to 1 specifies that the second PPS further comprises second conformance window parameters, and wherein when the first picture width parameter has a same value as the second picture width parameter and the first picture height parameter has a same value as the second picture height parameter, the first conformance window parameters have same values as the second conformance window parameters; and
encode the first PPS and the second PPS into a bitstream.
