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 method for transmitting broadcast signals includes encoding PLP data; building at least one signal frame by mapping the encoded PLP data; and modulating data in the built signal frame by OFDM method and transmitting a broadcast signal having the modulated data, wherein the signal frame includes a preamble having a preamble symbol and a guard interval, wherein the guard interval is generated by using a sequence and the preamble symbol. |

1. A method of alerting an emergency via broadcast signal transmission, the method including:
encoding PLP (Physical Layer Pipe) data; building at least one signal frame by mapping the encoded PLP data; and modulating data in the built signal frame by OFDM (Orthogonal Frequency Division Multiplexing) method and transmitting a broadcast signal having the modulated data, wherein the signal frame includes a preamble having a preamble symbol and a guard interval, wherein the guard interval is generated by using a sequence and the preamble symbol. |
