Apparatus for transmitting broadcast signals, apparatus for receiving broadcast signals, method for transmitting broadcast signals and method for receiving broadcast signals

摘要

The present invention provides a method of transmitting broadcast signals. The method includes, encoding, by an encoder, data in plural PLPs (Physical Layer Pipes); processing, by a framing and interleaving block, the encoded data in the plural PLPs, wherein the processing the encoded data further includes: time interleaving, by a time interleaver, the encoded data in the plural PLPs, frame mapping, by a framer, the time interleaved data onto at least one signal frame, and frequency interleaving, by a frequency interleaver, data in the at least one signal frame; and waveform modulating, by a waveform generation block, the frequency interleaved data in the at least one signal frame and transmitting, by the waveform generation block, broadcast signals having the waveform modulated data.

1. A method of receiving broadcast signals, the method including:
receiving, by a waveform block, the broadcast signals and demodulating, by the waveform block, the received broadcast signals; processing, by a parsing and deinterleaving block, the demodulated broadcast signals, wherein the processing further includes:
frequency deinterleaving, by a frequency deinterleaver, the demodulated broadcast signals, frame parsing, by a frame parser, at least one signal frame in the frequency deinterleaved broadcast signals, and
time deinterleaving, by a time deinterleaver, data in the parsed at least one signal frame,wherein the time deinterleaved data is split into a first layer data and a second layer data using injection level information; anddecoding, by a decoder, the first layer data and the second layer data, respectively.
