<p>The present invention relates to apparatus and method of transmitting and receiving broadcasting signals. One aspect of the present invention relates to a method of transmitting broadcasting signal to a receiver, comprising:
mapping preamble data bits into preamble data symbols and data bits into data symbols;
building at least one data slice based on the data symbols;
time-interleaving the preamble data symbols within an Layer 1 (L1) block;
building a signal frame based on the preamble data symbols and the data slice, the preamble data symbols comprising L signalling information for signalling the data slice;
modulating the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) method; and
transmitting the modulated signal frame.</p> |
