APPARATUS AND METHOD FOR SENDING AND RECEIVING BROADCAST SIGNALS |
| 摘要 |
Disclosed is a broadcast signal transmitter. The broadcast signal transmitter includes a first bit interleaved coded modulation (BICM) unit configured to forward error correction (FEC)-encode data of a first layer, a second BICM unit configured to FEC-encode data of a second layer, a layered division multiplexing (LDM) injection unit configured to combine the data of the first layer and the data of the second layer and to output LDM data, a framing and interleaving unit configured to interleave the LDM data and to generate a signal frame, and a waveform generation unit configured to perform OFDM modulation on the LDM data and to generate a broadcast signal. |

1. A broadcast signal transmitter, comprising:
a first bit interleaved coded modulation (BICM) unit configured to forward error correction (FEC)-encode data of a first layer; a second BICM unit configured to FEC-encode data of a second layer; a layered division multiplexing (LDM) injection unit configured to combine the data of the first layer and the data of the second layer and to output LDM data; a framing and interleaving unit configured to interleave the LDM data and to generate a signal frame; and a waveform generation unit configured to perform OFDM modulation on the LDM data and to generate a broadcast signal, wherein the framing and interleaving unit comprises a time interleaver configured to time-interleave the LDM data. |
