BROADCAST SIGNAL TRANSMITTING APPARATUS, BROADCAST SIGNAL RECEIVING APPARATUS, AND BROADCAST SIGNAL TRANSCEIVING METHOD IN BROADCAST SIGNAL TRANSMITTING AND RECEIVING APPARATUSES
First Claim
1. A method of processing broadcast data in a transmitter, the method comprising:
- formatting at least one input stream including data packets into one or multiple Physical Layer Pipes (PLPs) for a service;
Forward Error Correction (FEC) encoding PLP data of one or multiple PLPs;
bit interleaving the FEC-encoded PLP data;
time interleaving the bit-interleaved PLP data;
building a signal frame including the time-interleaved PLP data; and
transmitting a broadcast signal including data of the signal frame,wherein the signal frame further includes signaling information that contains mapping information for mapping between the input stream and one or multiple PLPs, and wherein the mapping information includes access information for accessing the input stream and PLP information for identifying the PLPs.

Abstract
Disclosed are a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a broadcast signal transceiving method in the broadcast signal transmitting and receiving apparatuses. The broadcast signal transmitting method comprises the steps of: compressing headers of data packets which are included in an Internet protocol (IP) stream identified by access information, wherein the compressed data packets include a first packet containing both static information and dynamic information in the header thereof, and a second packet containing dynamic information in the header thereof; splitting the static information from the header of the first packet and diverting the remaining part thereof into the second packet; outputting an IP stream, which includes the second packet, via a data physical layer pipe (PLP); outputting, via a common PLP, a common stream, which includes the static information of the header of the first packet split in the previous step, compression information and IP-PLP mapping information for linking the IP stream and the data PLP; generating a signal frame on the basis of the data from the data PLP and the data of the common PLP; and transmitting a broadcast signal which includes the signal frame.
