Abstract

See full text

A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals comprises an encoder for encoding Data Pipe (DP) data corresponding to each of a plurality of DPs, wherein each of a plurality of DPs carries at least one service component, a mapper for mapping the encoded DP data onto constellations, a time interleaver for time interleaving (TI) the mapped DP data at DP level by skipping cells having zero values of the DP data, a frame builder for building at least one signal frame including the time interleaved DP data, a modulator for modulating data in the built at least one signal frame by an Orthogonal Frequency Division Multiplex (OFDM) scheme and a transmitter for transmitting the broadcast signals having the modulated data.
