APPARATUS FOR TRANSMITTING BROADCAST SIGNALS, APPARATUS FOR RECEIVING BROADCAST SIGNALS, METHOD FOR TRANSMITTING BROADCAST SIGNALS AND METHOD FOR RECEIVING BROADCAST SIGNALS

摘要

A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus transmitting broadcast signals, the apparatus comprises an encoder for encoding data corresponding to each of the data transmission channel which carries at least one service data or service component data, a frame builder for building at least one signal frame including the encoded data, a modulator for modulating the at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme, a transmitter for transmitting the broadcast signals carrying the at least one modulated signal frame.
