METHOD AND APPARATUS FOR TRANSCEIVING BROADCAST SIGNALS |
摘要 |
Disclosed are a digital broadcast transmitter and receiver. The digital broadcast transmitter according to one embodiment of the present invention comprises: an SVC encoder for SVC encoding broadcast data into a base layer and an enhancement layer; a BICM module for bit interleaved coding and modulation (BICM) processing the base layer and the enhancement layer; a frame builder for building a frame including the base layer and the enhancement layer, which are BICM-processed; a MIMO processor for processing data contained in the frame by a MIMO, MISO and/or SISO scheme; and an OFDM generator for OFDM modulating the processed data and transmitting broadcast signals. In addition, the digital broadcast receiver according to one embodiment of the present invention comprises: an OFDM demodulation unit for receiving broadcast signals and OFDM demodulating the received signals; a MIMO decoder for MIMO decoding the demodulated broadcast signal and outputting a frame; a frame recovery unit for extracting a base layer and an enhancement layer from the frame; a BICM deprocessing module for BICM deprocessing the base layer and the enhancement layer; and an SVC decoder for SVC decoding the base layer and the enhancement layer to obtain broadcast data. |
