Abstract
(EN)
The broadcast-signal transmitter according to one embodiment of the present invention includes: an encoder for encoding physical layer pipe (PLP) data, including a base layer and an enhancement layer of a broadcasting service, and signaling information through a SISO, MISO, and/or MIMO technique; a frame builder for generating a transmission frame, which includes a preamble having the encoded signaling information and the PLP data; and an OFDM generator for modulating and transmitting a broadcast signal including the transmission frame.
