FIELD: radio engineering, communication.
SUBSTANCE: broadcast signal transmission device comprises: an encoder for encoding data from data pipeline (DP), corresponding to each of the DP plurality, wherein each of the DP plurality carries at least one service component; a depicter that displays DP encoded data in groups; a time interleaver for time interleaving mapped DP data on the DP level by passing the cells having zero values DP data; a frame builder for building at least one signal frame comprising interleaved in time DP data; a modulator for modulating data in at least one built signal frame by multiplexing scheme with Orthogonal Frequency Division Multiplexing (OFDM), and a transmitter for transmitting broadcast signals having the modulated data.
EFFECT: creation of transmission and reception of broadcast signals device.
