Claim:
1. A method for encoding a picture in a multi-layer bitstream, comprising: encoding at least one enhancement layer of the multi-layer bitstream based on a first coding scheme, the multi-layer bitstream comprising a base layer different from the enhancement layer; determining whether the base layer was coded based on the first coding scheme or a coding scheme associated with the first coding scheme; encoding a conformance window flag in a Video Parameter Set (VPS) of the base layer, the conformance window flag indicating whether the VPS comprises at least one position offset, the at least one position offset indicative of positioning information for the picture; and in response to determining that the base layer was coded based on the first coding scheme or a coding scheme associated with the first coding scheme, setting the conformance window flag to a first predetermined value, or in response to determining that the base layer was not coded based on the first coding scheme or a coding scheme associated with the first coding scheme: (i) setting conformance window flag to a second predetermined value different from the first predetermined value, the second predetermined value indicating the VPS comprises the at least one position offset, and (ii) encoding the at least one position offset in the VPS of the base layer.
