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 receiving 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, a time deinterleaver to time deinterleave data in the parsed signal frame and a decoder to decode the time deinterleaved data.

主权项

1. A method comprising:
receiving a broadcast signal; demodulating the received broadcast signal by an Orthogonal Frequency Division Multiplex (OFDM) scheme; parsing at least one signal frame from the demodulated broadcast signal; time deinterleaving data in the parsed at least one signal frame using a first mode or a second mode; and decoding the time deinterleaved data, wherein the demodulated broadcast signal includes
first signaling information indicating a position of a deinterleaving selector at the start of the signal frame in the first mode, orsecond signaling information indicating whether an inter-frame deinterleaving scheme is used in the time deinterleaving in the second mode.
