Abstract: In one embodiment, the method includes determining a reference field picture from a reference picture list composed of reference frames using index information for a reference field and index information for a reference frame. The determined reference field picture has a same parity as the current macroblock or a different parity from the current macroblock based on whether the index information for the reference field is an even number or a odd number. The determined reference field picture has a same parity as the current macroblock if the index information for the reference field is an even number. The determined reference field picture has a different parity from the current macroblock if the index information for the reference field is a odd number.

Abstract: In one embodiment, the method includes obtaining a reference picture list including multiple reference pictures, and determining an initial reference picture index of the multiple reference pictures in the reference picture list based on display order information for the multiple reference pictures. The reference picture index numbers increase for reference pictures having a decreasing display order with respect to a picture including the macroblock and the reference picture numbers increase for reference pictures having an increasing display order with respect to the picture including the macroblock. The reference picture index numbers of the reference pictures having a decreasing display order are less than the reference picture index numbers of the reference pictures having an increasing display order. The initial reference picture index is selectively modified to produce a determined reference picture index based on the macroblock level of the macroblock.

Abstract: The present invention relates to a method for coding a moving picture in a moving picture coding system using multiple reference picture. According to the method for coding an interlaced moving picture into a frame picture having frame/field macroblock, a reference picture index of the frame macroblock is determined at a macroblock level by determining the reference picture index of frame unit at a picture (or slice) level and respectively allocating a lower index and a higher index to a top reference field and a bottom reference field while sequentially visiting the reference frames according to an order of reference picture index of frame unit, the top and bottom field indexes being giving by an equation: top reference field index=2×picture index of reference frame; and bottom reference field index=2×picture index of reference frame+1.
