An encoder and a decoder, consisting of a wide screen EDTV system compatible with current NTSC equipment, have been developed. The system, however, showed some problems that required attention. Therefore, an advanced EDTV system, consisting of an improved wide screen EDTV system and an advanced scan converting system, was developed. The former improves picture quality of the side panels and extends horizontal resolution of the center panel. The latter improves vertical resolution without the motion artifact observed in a conventional scan converter.>
