APPARATUS FOR TRANSMITTING AND RECEIVING A SIGNAL AND METHOD OF TRANSMITTING AND RECEIVING A SIGNAL

摘要

A method of transmitting and receiving a signal and an apparatus for transmitting and receiving a signal are provided. The method includes receiving the signal of a first frequency band, obtaining Layer-1 (L1) information from a preamble of a first time-frequency slicing (TFS) signal frame of the received signal, the layer-1 information including a radio frequency (RF) channel identifier of the first TFS signal frame including a physical layer pipe (PLP) in a super frame of TFS structure and including an identifier of a starting radio RF channel that can receive the PLP in the first TFS signal frame, parsing the first TFS signal frame using the L1 information and obtaining a PLP of the first TFS signal frame, and converting the PLP to a service stream.

1. A method of processing broadcast signals, the method comprising:
outer encoding service data corresponding to a number of physical layer pipes (PLPs); inner encoding the outer encoded service data; twisted interleaving the inner encoded service data; forming a signal frame including the twisted interleaved service data; modulating the broadcast signals including the signal frame by an Orthogonal Frequency Division Multiplex (OFDM) scheme; and transmitting the broadcast signals, wherein the signal frame further includes a symbol comprising a first part, a second part and a third part, wherein the first part is generated from a portion of the second part, and wherein the third part is generated from a portion of the second part.
