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 for receiving broadcast signals, the apparatus comprises a receiver to receive the broadcast signals, a demodulator to demodulate the received broadcast signals by an OFDM (Orthogonal Frequency Division Multiplex) scheme, a frame parser to parse a signal frame from the demodulated broadcast signals, wherein the signal frame includes at least one service data, a time deinterleaver to time deinterleave each the service data, wherein the time deinterleaving is performed depending on a number of physical paths for each the service data, a damapper to demap the time deinterleaved data and a decoder to decode the demapped service data.

1. A method for receiving broadcast signals, the method comprising:
receiving the broadcast signals; demodulating the received broadcast signals by an OFDM (Orthogonal Frequency Division Multiplex) scheme; parsing a signal frame from the demodulated broadcast signals, wherein the signal frame includes at least one service data; time deinterleaving each the service data, wherein the time deinterleaving is performed depending on a number of physical paths for each the service data; demapping the time deinterleaved data; and decoding the demapped service data.
