Abstract

A digital broadcasting system is provided. The system includes an RS (Reed-Solomon) encoder configured to encode mobile service data for FEC (Forward Error Correction) to build RS frames including the mobile service data and a signaling information table, a signaling encoder configured to encode signaling information including fast information channel (FIC) data and transmission parameter channel (TPC) data, a group formatter configured to form data groups, wherein at least one of the data groups includes encoded mobile service data, known data sequences, the FIC data and the TPC data, and a transmission unit configured to transmit the broadcast signal including a parade of the data groups.

First claim

The invention claimed is:

1. A transmitting system for transmitting a broadcast signal, the transmitting system comprising:
an encoder for encoding service data for FEC (Forward Error Correction);
a signaling encoder for encoding signaling information for fast service acquisition;
a generator for generating a data unit that includes the encoded service data and the encoded signaling information; and
a transmission unit for transmitting the broadcast signal that includes the data unit,
wherein the signaling information includes information for identifying a broadcast stream via which the signaling information is transmitted, information indicating a number of services in the identified broadcast stream, information indicating if each of the services is protected and information indicating a channel number of each of the services.

2. The transmitting system of claim 1 , wherein:
the broadcast signal further includes transmission parameters for the service data; and
the transmission parameters include a code rate.

3. The transmitting system of claim 2 , wherein the transmission parameters further include version information indicating a version of the signaling information for the fast service acquisition.

4. The transmitting system of claim 1 , wherein the broadcast signal further includes a signaling information table to access a service of the service data.

5. A method for transmitting a broadcast signal, the method comprising:
encoding service data for FEC (Forward Error Correction);
encoding signaling information for fast service acquisition;
generating a data unit that includes the encoded service data and the encoded signaling information; and
transmitting the broadcast signal that includes the data unit,
wherein the signaling information includes information for identifying a broadcast stream via which the signaling information is transmitted, information indicating a number of services in the identified broadcast stream, information indicating if each of the services is protected and information indicating a channel number of each of the services.

6. The method of claim 5 , wherein:
the broadcast signal further includes transmission parameters for the service data; and
the transmission parameters include a code rate.

7. The method of claim 6 , wherein the transmission parameters further include version information indicating a version of the signaling information for the fast service acquisition.

8. The method of claim 5 , wherein the broadcast signal further includes a signaling information table to access a service of the service data.
