1. A method of decoding a coded video bitstream implemented by a video decoder, the method comprising:
obtaining a first reference picture list syntax structure and a second reference picture list syntax structure represented in the coded video bitstream for all types of slices, wherein each reference picture list syntax structure contains a number of entries; and
deriving, based on the first reference picture list syntax structure and the second reference picture list syntax structure, a first reference picture list of a current slice and a second reference picture list of the current slice, wherein the current slice comprises an intra (I) slice, a uni-predictive (P) slice, or a bi-predictive (B) slice, and wherein the first reference picture list and the second reference picture list are derived for bitstream conformance checking instead of for decoding when the current slice comprises the I slice.
