Selecting a reference picture using index information

摘要

At least one reference picture for processing a field macroblock is selected from at least one reference picture list using reference picture index information. Each selected reference picture is a field and if the reference picture index information is an odd number, then the selected reference picture has a different field parity to the field macroblock. Each reference field may be a field of a reference frame and may be a top field or a bottom field. The method relates to video coding systems using motion compensation.
