A method of decoding a coded video bitstream implemented by a video decoder based on the VVC standard, characterized in that, the method comprising: parsing a parameter set represented in the coded video bitstream, wherein the parameter set comprises a sequence parameter set; wherein the sequence parameter set comprises a set of reference picture list syntax structures, ref_pic_list_struct( listldx, rplsIdx), wherein ref_pic_list_struct (listIdx, rplsIdx) is defined as ref_pic_list_struct( listldx, rplsIdx) { Descriptor num_strp_entries [ listIdx][ rplsIdx] ue(v) for( i = 0; i < NumEntriesInList[ listIdx][ rplsIdx]; i++) { delta_poc_st [ listIdx][ rplsIdx][ i] se(v)}} wherein ref_pic_list_struct( listldx, rplsIdx) contains num_strp_entries[ listIdx][ rplsIdx]specifying the number of short term reference picture, STRP, entries in the ref_pic_list_struct( listldx, rplsIdx), wherein ref_pic_list_struct( listldx, rplsIdx) contains delta_poc_st[ listIdx][ rplsIdx][ i], wherein delta_poc_st[ listIdx][ rplsIdx][ i] specifies the difference between the picture order count values of the current picture and the picture referred to by the i-th entry when the i-th entry is the first STRP entry in ref_pic_list_struct( listldx, rplsIdx) syntax structure, or delta_poc_st[ listIdx][ rplsIdx][ i] specifies the difference between the picture order count values of the pictures referred to by the i-th entry and by the previous STRP entry in the ref_pic_list_struct( listldx, rplsIdx) syntax structure when the i-th entry is an STRP entry but not the first STRP entry in the ref_pic_list_struct( listldx, rplsIdx) syntax structure, wherein ref_pic_list_struct( listldx, rplsIdx) comprises a first parameter listIdx and a second parameter rplsldx, the rplsIdx specifies an index of a reference picture list syntax structure, listIdx has a value to specify a reference picture list, wherein the value of the listldx equals to 0 or 1; wherein the reference picture list syntax structure is represented in an SPS and specifies a candidate for short-term reference picture list listIdx, and the current picture refers to each picture that 1) has one or more slices containing ref_pic_list_idx[ listIdx] equal to an index into the list of the ref_pic_list_struct( listldx, rplsIdx) syntax structures included in the SPS, and 2) is in a CVS that has the SPS as the active SPS,; parsing a slice header of a current slice represented in the coded video bitstream, wherein the slice header comprises an index of a reference picture list syntax structure among the set of reference picture list syntax structures in the parameter set; deriving, based on the set of reference picture list syntax structures and the index of the reference picture list syntax structure, a reference picture list of the current slice, and obtaining, based on the reference picture list, at least one reconstructed block of the current slice. wherein ref_pic_list_struct( listldx, rplsIdx) contains num_strp_entries[ listIdx][ rplsIdx]specifying the number of short term reference picture, STRP, entries in the ref_pic_list_struct( listldx, rplsIdx), wherein ref_pic_list_struct( listldx, rplsIdx) contains delta_poc_st[ listIdx][ rplsIdx][ i], wherein delta_poc_st[ listIdx][ rplsIdx][ i] specifies the difference between the picture order count values of the current picture and the picture referred to by the i-th entry when the i-th entry is the first STRP entry in ref_pic_list_struct( listldx, rplsIdx) syntax structure, or delta_poc_st[ listIdx][ rplsIdx][ i] specifies the difference between the picture order count values of the pictures referred to by the i-th entry and by the previous STRP entry in the ref_pic_list_struct( listldx, rplsIdx) syntax structure when the i-th entry is an STRP entry but not the first STRP entry in the ref_pic_list_struct( listldx, rplsIdx) syntax structure, wherein ref_pic_list_struct( listldx, rplsIdx) comprises a first parameter listIdx and a second parameter rplsldx, the rplsIdx specifies an index of a reference picture list syntax structure, listIdx has a value to specify a reference picture list, wherein the value of the listldx equals to 0 or 1; wherein the reference picture list syntax structure is represented in an SPS and specifies a candidate for short-term reference picture list listIdx, and the current picture refers to each picture that 1) has one or more slices containing ref_pic_list_idx[ listIdx] equal to an index into the list of the ref_pic_list_struct( listldx, rplsIdx) syntax structures included in the SPS, and 2) is in a CVS that has the SPS as the active SPS,; parsing a slice header of a current slice represented in the coded video bitstream, wherein the slice header comprises an index of a reference picture list syntax structure among the set of reference picture list syntax structures in the parameter set; deriving, based on the set of reference picture list syntax structures and the index of the reference picture list syntax structure, a reference picture list of the current slice, and obtaining, based on the reference picture list, at least one reconstructed block of the current slice.
