Abstract
A method and apparatus for transmitting a digital television signal using a first multipoint constellation comprised of a plurality of identical second constellations each having fewer points than the first constellation and each positioned in a different section of the first constellation. The receiver includes a decoder which decodes data as encoded in one of the second constellations. Additional bits, transmitted with the data, are also decoded at the receiver to identify which to section of the first constellation the second constellation belongs.
