Abstract:
A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals, the apparatus comprises an encoder for encoding service data corresponding to each of a plurality of data transmission path, wherein each of the data transmission path carries at least one service component, a frame builder for building at least one signal frame included in a super frame, wherein each of signal frames includes the encoded service data and the encoded signaling data, a modulator for modulating the at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme, wherein each of the modulated signal frame includes a preamble having basic transmission parameters, wherein a length of the preamble is extendable and a transmitter for transmitting the broadcast signals carrying the at least one modulated signal frame.
