In one embodiment, the method includes obtaining a first reference frame picture list and a second reference frame picture list including multiple reference frame pictures respectively. A reference frame picture index is determined based on display order information for the multiple reference frame pictures. The method further includes obtaining first motion vector information and second motion vector information for the macroblock and obtaining a first reference field picture index and a second reference field picture index associated with the macroblock. A first reference frame picture and a second reference frame picture are determined. The method further includes selecting first and second reference field pictures for the macroblock. The macroblock is decoded based on the first and second motion vector information and the selected first and second reference field pictures.
