Abstract: A transmission method, a device, a record medium, and receiving device of digital broadcasting signal are provided to multiplex a plurality of service information in a transmission frame to a frequency domain and time domain, and to transmit the plurality of service information in different formats. A encoding unit(310) encodes digital data about M service according to a request of the corresponding service. An M digital modulator(320) modulates the channel encoded service data outputted from the encoding unit. A allocation unit(330) assigns one or more sub-bands and symbols to service data which are digital modulated from the digital modulator. An IFFT(Inverse Fast Fourier Transform) part(340) converts a signal in a frequency domain for M service data outputted from the allocation unit into a signal of a time domain. A frame generator(350) produces a plurality of symbol durations to a frame body of one transmission frame. The frame generator produces a frame header including the information about M service data. A D/A converter(360) converts a transmission frame of a digital signal outputted from the frame generator and transmits the transmission frame converted into an analog signal to a receiving device.

Abstract: A method and an apparatus for hierarchical modulation/demodulation in an OFDM(Orthogonal Frequency Division Multiplexing) system are provided to perform an in-phase demodulation by using a pilot which is transferred to a second layer. A hierarchical modulation apparatus in an OFDM system includes first and second encoders(110,120), a pilot insertion unit(130), and a hierarchical modulation unit(140). The first encoder encodes a first layer signal stream, which is a basic layer signal. The second encoder encodes a second layer signal stream which is an enhancement layer signal. The pilot insertion portion inserts a pilot signal for estimating a channel coefficient to an encoded second layer signal stream. The hierarchical modulation portion modulates the second layer signal stream, to which the pilot signal is inserted, and the encoded first layer signal stream, and combines the encoded signals with each other.
