Abstract
A method for encoding mode signals of a target block of M.times.N pixels having a binary value `0` or `255` is provided. If the target block is determined as neither 'all.sub.-- 0' nor 'all.sub.-- 255', either a frame-based coding or a field-based coding is selected to generate a coding mode signal, wherein the frame-based coding represents the target block is encoded on an M.times.N pixels basis and the field-based coding represents the target block is encoded on an M/2.times.N pixels basis, and a base mode of the target block based on the 'all.sub.-- 0', 'all.sub.-- 255' and/or the coding mode signal. If the frame-based coding is selected, a frame mode is generated. On the contrary, if the field-based coding is selected, the frame is divided into a top and a bottom fields so that a top mode for the top field and a modified bottom mode for the bottom field are obtained, wherein a bottom mode is modified by the top mode to be the modified bottom; and the top mode and the modified bottom mode are attached to be a field mode.
