Abstract: An apparatus for transmitting digital multimedia broadcasting includes: a base layer processor that outputs a base layer stream; an enhancement layer processor that outputs an enhancement layer stream; and a transmitter that modulates the enhancement layer stream based on one of a first and second hierarchical modulation modes using different modulation schemes and maps a symbol of the modulated enhancement layer stream based on a symbol position of the base layer stream to generate a transmission frame.
