Abstract
An apparatus including an encoder for encoding service data corresponding to each of a plurality of data transmission path, an encoder for encoding signaling data, wherein the signaling data includes static data and dynamic data, a frame builder for building signal frames, wherein each of signal frames includes the encoded service data and the encoded signaling data, wherein each of signal frames belongs to one of the broadcast services, wherein the static data remain constant in the signal frames belonging to the broadcast service in a duration of a super frame and the dynamic data changes by the signal frames, a modulator for modulating the signal frames by an OFDM (Orthogonal Frequency Division Multiplex) scheme and a transmitter for transmitting the broadcast signals carrying the modulated signal frames.
