Abstract

A digital broadcast receiving system and a method for controlling the same are disclosed. The method a method for controlling a digital broadcast receiving system includes the steps of receiving a broadcast signal having mobile service data and main service data multiplexed therein, extracting transmission parameter channel (TPC) signaling information and fast information channel (FIC) signaling information from a data group within the received mobile service data, acquiring a program table, by using the IP signaling channel within an ensemble included in the received broadcast signal, and controlling the system to create a list of channels mapped with all ensembles transmitted through at least one physical frequency, by using the acquired program table.

Claims

1. A method of transmitting a broadcast signal in a transmitter, the method comprising:

transmitting a transmission frame including a plurality of slots during which data groups of mobile data are transmitted, the mobile data being encoded through a Reed-Solomon (RS) frame, each row of a payload of the RS frame including a transport packet of the mobile data,

wherein each data group includes a plurality of regions, each of the plurality of regions including a plurality of data blocks and each of the plurality of data blocks including contiguous data segments,

wherein first and second regions in each data group include at least three known data sequences which are spaced apart by regular data segments, and the first region further includes signaling information of the mobile data in specified data segments,

wherein the signaling information includes first channel information providing binding information between a mobile service identifier and an ensemble being a collection of services of the mobile data, and second channel information describing the transmission frame and the data groups,

wherein the ensemble includes a signaling table describing a service, and

wherein the signaling table includes an identifier of the service and a short name of the service.

2. The method of claim 1, wherein the ensemble further includes a service map table (SMT) providing IP address information for the service.

3. The method of claim 1, wherein the transport packet includes an Internet protocol (IP) datagram.

4. The method of claim 3, wherein the IP datagram includes the signaling table.

5. A method of receiving a broadcast signal in a receiver, the method comprising:

receiving a transmission frame including a plurality of slots during which data groups of mobile data are received, the mobile data being data encoded through a Reed-Solomon (RS) frame, each row of a payload of the RS frame including a transport packet of the mobile data,

wherein each data group includes a plurality of regions, each of the plurality of regions including a plurality of data blocks and each of the plurality of data blocks including contiguous data segments,

wherein first and second regions in each data group include known data sequences which are spaced regular data segments apart, and the first region further includes a known data sequence and signaling information of the mobile data in specified data segments,

wherein the signaling information includes first channel information providing binding information between a mobile service identifier and an ensemble being a collection of services of the mobile data, and second channel information describing the transmission frame and the data groups,

wherein the ensemble includes a signaling table describing a service, and

wherein the signaling table includes an identifier of the service and a short name of the service;

building the RS frame using the data groups included in the transmission frame; and

decoding the RS frame.

6. The method of claim 5, wherein the ensemble further includes a service map table (SMT) providing IP address information for the service.

7. The method of claim 5, wherein the transport packet includes an Internet protocol (IP) datagram.

8. The method of claim 7, wherein the IP datagram includes the signaling table.
