Transmission of all-digital advanced television: state of the art and future directions

All-digital high definition television (HDTV) and advanced television (ATV) systems have been proposed in the United States and Europe for terrestrial as well as satellite broadcasting. The main goals of the paper are to describe and discuss the theory and methods for error control, modulation and equalization used by these HDTV and ATV systems. The author identifies their similarities and differences in their error control, modulation and equalization methods and discusses possible improvements to them. He also describes recent research directions and trends in error control which pays much more attention to advanced and relatively new theory and techniques in information, coding, and communication theory. Finally, his views are provided, based on the above, about the best choices for error control schemes. The specific HDTV and ATV systems which have been proposed and, in most cases, built and tested in various ways, are described.<
