    摘要: The present invention relates to an apparatus for transmitting broadcast signals, an apparatus for receiving broadcast signals and methods for transmitting and receiving broadcast signals. The method of transmitting broadcast signals includes encoding data corresponding to each of data transmission channel which carries at least one service data or service component data, building at least one signal frame including the encoded data, modulating the at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme; and transmitting the broadcast signals carrying the at least one modulated signal frame.

    摘要: The present invention provides a method of transmitting broadcast signals. The method includes encoding service data of Physical Layer Pipes (PLPs); bit interleaving the encoded service data; building at least one signal frame including the bit interleaved service data; and modulating data in the at least one signal frame by Orthogonal Frequency Division Multiplexing (OFDM) method; inserting a preamble at a beginning of each of the at least one signal frame after the modulating step; and transmitting the broadcast signals having the modulated data, wherein the preamble includes information for a size of Fast Fourier Transform (FFT), a guard interval and a pilot mode, wherein the preamble includes two OFDM symbols, and wherein each of the two OFDM symbols in the preamble includes information for an emergency alert.
