## Abstract

The present invention provides a data processing method that includes receiving a broadcasting signal in which mobile service data are multiplexed with main service data, extracting transmission-parameter-channel signaling information and fast-information-channel (FIC) signaling information from a data group within the received mobile service data, parsing first program table information describing virtual channel information of an ensemble and a service provided by the ensemble using the FIC signaling information, the ensemble corresponding to a virtual channel group of the received mobile service data, obtaining information from the first program table information, the information representing that second program table information including a descriptor describing event information of the mobile service data is received, parsing the second program table information, storing the event information and displaying service guide information including the event information.

## Claims

### Claim 1

A method of processing broadcast service data in a broadcast transmitter, the method comprising:
encoding service acquisition data carrying information to enable service acquisition;
FEC (Forward Error Correction) encoding broadcast service data;
encoding the FEC encoded broadcast service data;
encoding transmission parameters for transmission of the broadcast service data;
generating data frames including the encoded broadcast service data and the encoded transmission parameters; and
transmitting broadcast signals including the data frames and the encoded service acquisition data,
wherein the broadcast signals further include service information data describing a broadcast service,
wherein the service acquisition data includes version information specifying a version of a protocol for the service information data,
wherein the service acquisition data further includes location information specifying a location where the service information data is carried, and
wherein the service information data includes address information specifying an Internet Protocol (IP) address of a transmission session that delivers a component of the broadcast service.

### Claim 2 (depends on 1)

The method of claim 1,
wherein the service acquisition data further includes type information specifying a category of the broadcast service.

### Claim 3 (depends on 1)

The method of claim 1,
wherein the service acquisition data further includes activity information specifying a status of the broadcast service.

### Claim 4 (depends on 1)

The method of claim 1,
wherein the service information data includes component number information specifying a list of the components of the broadcast service.
