<p>A method for encoding a BAB type of a target block of an interlaced shape signal is provided. After no-update BAB-type which does not require supplemental encoded data is determined, either frame-basis or field-basis encoding is selected as an encoding-type based on a degree of correlation between the target block and its two field blocks. If field basis encoding is selected as encoding-type, it is determined whether or not said two field blocks correspond to one-field-no-update, which indicates at least one field of said two field blocks require no supplemental data to be transmitted. If said two field blocks are decided as one-field-no-update, top-or-bottom and BAB-type-field are detected to be encoded.</p> |
