## Abstract

A method of transmitting a broadcast signal includes encoding mobile service data to build a Reed-Solomon (RS) frame according to an RS frame mode, wherein the mobile service data is either a mobile service data of a base layer or a mobile service data of the base layer and at least one enhancement layer, wherein each layer is specified by a layer identifier, wherein a layer identifier value of the base layer is set to 0 and a layer identifier value of the at least one enhancement layer starts from 1; and encoding signaling data, wherein the signaling data includes fast information channel (FIC) data and transmission parameter channel (TPC) data, and the FIC data includes information for rapid mobile service acquisition.

## Claims

### Claim 1

A method for transmitting a broadcast signal, the method comprising:
encoding service data for FEC (Forward Error Correction);
encoding first signaling data for rapid service acquisition;
allocating the encoded service data and the encoded first signaling data into a signal frame; and
transmitting the broadcast signal including the signal frame, wherein the signal frame includes second signaling data for accessing a service of the service data, wherein the second signaling data includes third signaling data having information for components of the service.

### Claim 2 (depends on 1)

The method of claim 1, wherein the third signaling data includes elements for indicating different coded versions of the same components of the service, and
wherein each of the elements includes identification information identifying said each of the elements and reference information indicating other elements used to decode said each of the elements.

### Claim 3 (depends on 1)

The method of claim 1, wherein the second signaling data further includes information indicating a name of the service of the service data.

### Claim 4

An apparatus for transmitting a broadcast signal, the apparatus comprising:
a first encoder configured to encode service data for FEC (Forward Error Correction);
a second encoder configured to encode first signaling data for rapid service acquisition; and
a transmitter configured to allocate the encoded service data and the encoded first signaling data into a signal frame and transmit the broadcast signal including the signal frame, wherein the signal frame further includes second signaling data for accessing a service of the service data, wherein the second signaling data includes third signaling data having information for components of the service.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the third signaling data includes elements for indicating different coded versions of the same components of the service, and
wherein each of the elements includes identification information identifying said each of the elements and reference information indicating other elements used to decode said each of the elements.

### Claim 6 (depends on 4)

The apparatus of claim 4, wherein the second signaling data further includes information indicating a name of the service of the service data.
