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.

First claim

What is claimed is:

1. A method for transmitting broadcast signals, the method comprising:
input processing input streams to generate data of PLPs (Physical Layer Pipes) carrying at least one service or at least one service component;
encoding the data;
mapping the encoded data onto constellations;
MIMO (Multiple-Input Multiple-Output) processing the mapped data;
time interleaving the MIMO processed data;
building at least one signal frame including the time interleaved…
