Abstract

A method of transmitting broadcast signals includes forward error correction (FEC) encoding mobile data; interleaving the FEC encoded mobile data; encoding signaling information for the mobile data; mapping the interleaved mobile data and the encoded signaling information into a data unit, wherein the data unit includes a first region and a second region, wherein the first region is concatenated with the second region, wherein the first region includes known data and the encoded signaling information, and wherein the second region includes known data and the encoded mobile data; and transmitting the broadcast signals including the data unit, wherein the data unit is multiplexed with a data unit of main data in a specific time period, wherein the signaling information includes information of the data unit having the interleaved mobile data.

Claims

1. A method of transmitting broadcast signals, the method comprising:

forward error correction (FEC) encoding service data;

interleaving the FEC encoded service data;

encoding signaling information for the service data;

mapping the interleaved service data and the encoded signaling information into a data unit,

wherein the data unit includes a first region and a second region,

wherein the first region is concatenated with the second region,

wherein the first region includes first known data and the encoded signaling information, and

wherein the second region includes second known data and the interleaved service data; and

transmitting the broadcast signals including the data unit,

wherein the interleaved service data is multiplexed with different service data,

wherein the signaling information includes code rate information of the FEC encoding.

2. The method of claim 1, wherein the second known data are equally spaced in the second region.

3. The method of claim 1, wherein the data unit includes service signaling information for a service related to the service data.

4. An apparatus of transmitting broadcast signals, the apparatus comprising:

an encoder to forward error correction (FEC) encode service data;

an interleaver to interleave the FEC encoded service data;

a signaling encoder to encode signaling information for the service data;

a mapper to map the interleaved service data and the encoded signaling information into a data unit,

wherein the data unit includes a first region and a second region,

wherein the first region is concatenated with the second region,

wherein the first region includes first known data and the encoded signaling information, and

wherein the second region includes second known data and the interleaved service data; and

a transmitter to transmit the broadcast signals including the data unit,

wherein the interleaved service data is multiplexed with different service data,

wherein the signaling information includes code rate information of the FEC encoding.

5. The apparatus of claim 4, wherein the second known data are equally spaced in the second region.

6. The apparatus of claim 4, wherein the data unit includes service signaling information for a service related to the service data.
