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 at least one signal frame from the demodulated broadcast signals, wherein a signal frame includes service data corresponding to each of a plurality of physical paths, a time deinterleaver to time deinterleave service data in the at least one signal frame, a decoder to decode the time deinterleaved 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 at least one signal frame from the demodulated broadcast signals, wherein a signal frame includes service data corresponding to each of a plurality of physical paths; time deinterleaving service data in the at least one signal frame, wherein the time deinterleaving includes: convolutional deinterleaving the service data spread over the at least one signal frame to output at least one TI (Time interleaving) block, wherein the TI block is split into interleaving units and the interleaving units are spread over the at least one signal frame; and twisted block deinterleaving the convolutional deinterleaved service data in each physical path by a TI (Time interleaving) block in a signal frame; and decoding the time deinterleaved service data.
