| 1. A method of encoding a picture in an image sequence, comprising:
dividing said picture into a plurality of smaller portions;
selectively encoding at least one of said plurality of smaller portions at a time in frame coding mode and at least one of
said plurality of smaller portions at a time in field coding mode to form an encoded picture; and
skipping at least one macroblock within said at least one of smaller portions from being encoded if said picture is a predictive
coded picture or a bi-predictive coded picture,
wherein each of said smaller portions has a size that is larger than one macroblock.
