Broadcasting signal transmission device, broadcasting signal reception device, and method for transmitting/receiving broadcasting signal using same

A method for transmitting broadcast signals by a broadcast signal transmitter, the method comprising:

• encoding Physical Layer Pipe (PLP) data carried in each of a plurality of Physical Layer Pipes (PLPs), each PLP carries at least one broadcast service component of a service;
• interleaving the encoded PLP data;
• building a signal frame by mapping the interleaved PLP data into data symbols of the signal frame;
• modulating data of the built signal frame by an Orthogonal Frequency Division Multiplex (OFDM) scheme;
• and
• transmitting the broadcast signals including the data of the signal frame,
• wherein the broadcast signals further include first signaling information including service identification (ID) information and service name information, and
• wherein the broadcast signals further include second signaling information including mapping information between ID information for the PLPs and internet protocol (IP) addresses of the service described in the first signaling information.

An apparatus for transmitting broadcast signals, the apparatus comprising:

• an encoder to encode Physical Layer Pipe (PLP) data carried in each of a plurality of Physical Layer Pipes (PLPs), each PLP carries at least one broadcast service component of a service;
• an interleaver to interleave the encoded PLP data;
• a frame builder to build a signal frame by mapping the interleaved PLP data into data symbols of the signal frame,
• an Orthogonal Frequency Division Multiplex (OFDM) modulator to modulate the built signal frame by an OFDM scheme;
• and
• a transmitter to transmit the broadcast signals including the modulated signal frame,
• wherein the broadcast signals further include first signaling information including service (ID) identification information and service name information, and
• wherein the broadcast signals further include second signaling information including mapping information between ID information for the PLPs and internet protocol (IP) addresses of the service described in the first signaling information.

A method for receiving broadcast signals by a broadcast signal receiver, the method comprising:

• receiving the broadcast signals;
• demodulating the received broadcast signals by an Orthogonal Frequency Division Multiplex (OFDM) scheme;
• parsing a signal frame including data symbols in the demodulated broadcast signals,
• wherein the data symbols carry a plurality of Physical Layer Pipes (PLPs);
• deinterleaving Physical Layer Pipe (PLP) data carried in the plurality of PLPs;
• and
• decoding the deinterleaved PLP data carried in each of the plurality of PLPs,
• wherein each PLP carries at least one broadcast service component of a service,
• wherein the broadcast signals include first signaling information including service identification (ID) information and service name information, and
• wherein the broadcast signals further include second signaling information including mapping information between ID information for the PLPs and internet protocol (IP) addresses of the service described in the first signaling information.
