Abstract
A broadcast signal receiver according to the present invention comprises: a demodulator for performing OFDM demodulation on a received broadcast signal including a frame for the delivery of a broadcast service: a frame demapper for outputting the frame, the frame including a preamble that contains first signaling information, and a plurality of link-layer-pipes (LLPs) that contain PLP data, second signaling information and third signaling information, with the PLP data including a base layer and an enhancement layer of the broadcast service; and a decoder for decoding the first signaling information, for decoding the second and third signaling information, and for selectively decoding the PLP data by using the third signaling information.
