Document Type and Number:
WIPO Patent Application WO/2015/002449
Kind Code:
A1
Abstract:
A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals comprises an encoder for encoding service data corresponding to each of a plurality of data transmission units, an encoder for encoding physical signaling data by a shortening scheme and a puncturing scheme, a mapper for mapping the encoded service data onto constellations, a frame builder for building at least one signal frame including preamble data, a modulator for modulating the at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme, a transmitter for transmitting the broadcast signals carrying the at least one modulated signal frame.
