<p>The present invention relates to a method for transmitting a signal. The method comprises outputting a frame including a service stream; performing an error-correction for the service stream to output error-corrected data; generating network information for a delivery system delivering the service stream and service description information describing the service stream; mapping the error-corrected data to symbols, and generating a signal frame including the symbols, the signal frame having a plurality of time slicing regions in each of a plurality of frequencies; modulating the signal frame by using an orthogonal frequency divisional multiplexing scheme and inserting a guard interval into the modulated signal frame; and transmitting the modulated signal frame via an analogue signal, wherein the symbols of the service stream are shifted in direction of time and frequency. The invention also relates to a corresponding method of receiving a signal and to corresponding receiver and transmitter.</p> |
