TRANSMISSION METHOD, APPARATUS AND RECORD MEDIUM OF DIGITAL BROADCASTING SIGNAL AND RECEPTION APPARATUS THEREOF

摘要

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.
