variables as its field marked as "used for reference". When a reference entry is marked as "not available for reference list construction" in the following process, both of its fields are also marked as "not available for reference list construction". When refPicListConstructionFlag is equal to 1, the following applies: If useRefBasePicFlag is equal to 0, all reference entries that are marked as "reference base picture" are marked as "not available for reference list construction". NOTE 2 - When useRefBasePicFlag is equal to 0, only reference entries that are not marked as "reference base picture" are considered as present for the purpose of reference picture lists construction. Otherwise (useRefBasePicFlag is equal to 1), all reference entries for which one of the following conditions is true are marked as "not available for reference list construction": the reference entry is not marked as "reference base picture", the reference entry is marked as "used for short-term reference", and there exists a reference entry with the same value of FrameNum that is marked as "reference base picture" and "used for short-term reference", the reference entry is not marked as "reference base picture", the reference entry is marked as "used for long-term reference", and there exists a reference entry with the same value of LongTermFrameldx that is marked as "reference base picture" and "used for long-term reference". NOTE 3 - When useRefBasePicFlag is equal to 1 and either two short-term reference entries have the same value of FrameNum or two long-term reference entries have the same value of LongTermFrameldx (one of these reference entries is marked as "reference base picture" and the other reference entry is not marked as "reference base picture"), only the reference entry marked as "reference base picture" is considered as present for the purpose of reference picture lists construction.
