Original Abstract Submitted
a method of decoding a coded video bitstream is provided. the method includes parsing a parameter set represented in the coded video bitstream. the parameter set contains a set of syntax elements that include a set of reference picture list structures. the method also includes parsing a slice header of a current slice represented in the coded video bitstream. the slice header contains an index of a reference picture list structure among the set of reference picture list structures in the parameter set. the method further includes deriving, based on the set of syntax elements in the parameter set and the index of the reference picture list structure, a reference picture list of the current slice. the method also includes obtaining, based on the reference picture list, at least one reconstructed block of the current slice.
