Broadcast signal transmitting apparatus, broadcast signal receiving method, broadcast signal transmitting method, and broadcast signal receiving apparatus |
摘要 |
The present invention relates to a broadcast signal transmitting apparatus for transmitting a broadcast signal, a broadcast signal receiving apparatus for receiving a broadcast signal, and a method for transmitting and receiving a broadcast signal. A broadcast signal transmitting method according to the present invention may comprise the steps of: encoding data pipe (DP) data corresponding to each of a plurality of DPs that transmit one or more service components; mapping the encoded DP data to data symbols to generate one or more signal frames; modulating data existing in the one or more signal frames through an OFDM scheme; and transmitting a broadcast signal having the modulated data. |

1. A method for transmitting a broadcast signal, the method comprising:
encoding data pipe (DP) data corresponding to each of a plurality of DPs; mapping the encoded DP data to data symbols to generate at least one signal frame; modulating data in the at least one signal frame using an orthogonal frequency division multiplex (OFDM) scheme; inserting a preamble at a beginning of each of the at least one signal frame in a time domain; and transmitting a broadcast signal having the modulated data of the at least one signal frame, wherein the preamble includes emergency alert information. |
