APPARATUS AND METHOD FOR SENDING AND RECEIVING BROADCAST SIGNALS

摘要

Disclosed is an apparatus for transmitting a broadcast signal including: an input formatter module configured to de-multiplex an input stream into at least one data pipe (DP); a BICM module configured to perform error correction on data of the at least one DP; a frame building module configured to generate a signal frame including the data of the DP; and an OFDM generation module configured to generate a transmission signal by inserting a preamble into the signal frame and performing OFDM modulation thereon.

1. An apparatus for transmitting a broadcast signal, the apparatus comprising:
an input formatter module configured to de-multiplex an input stream into at least one data pipe (DP); a BICM module configured to perform error correction on data of the at least one DP; a frame building module configured to generate a signal frame including the data of the DP; and an OFDM generation module configured to generate a transmission signal by inserting a preamble into the signal frame and performing OFDM modulation, wherein the input formatting module comprises: a header compression module configured to compress IP headers of IP packets included in an IP stream when the input stream is the IP stream; a baseband (BB) frame slicer module configured to allocate data of the IP packets to a BB frame; and a BB frame header insertion module configured to insert a BB frame header into the BB frame.
