Abstract
The present invention provides a method of transmitting broadcast signals. The method includes, processing input streams into BB (Base Band) frames of PLPs (Physical Layer Pipes); encoding data of the PLPs; building at least one signal frame by mapping the encoded data of the PLPs; and modulating data in the built signal frame by OFDM (Orthogonal Frequency Division Multiplexing) method and transmitting the broadcast signals having the modulated data, wherein the signal frame includes PLS (Physical Layer Signaling) data having signaling information for the data of the PLPs.
