Method of decoding a macroblock based on a macroblock level of the macroblock

摘要

In one embodiment, the method includes obtaining a reference frame picture list including multiple reference frame pictures and determining reference frame picture index of the multiple reference frame pictures in the reference frame picture list based on display order information for the multiple reference frame pictures. Motion vector information for the current field macroblock and a reference field picture index associated with the current field marcoblock are obtained. A reference field picture having a different parity from the current field macroblock is selected if the reference field picture index is an odd value. The current macroblock is decoded based on the motion vector information and the selected reference field picture.
