Abstract

A method of transmitting a broadcast signal includes encoding mobile data for FEC (Forward Error Correction); encoding signaling information for signaling the mobile data; allocating the encoded mobile data and signaling data into a transmission frame; and transmitting the broadcast signal including the transmission frame, wherein the transmission frame includes a service signaling table having service_type information identifying a type of a service of the mobile data and hidden information indicating whether the service of the mobile data is hidden or not.

Claims

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

encoding service data for FEC (Forward Error Correction);

encoding signaling information for signaling the service data;

forming a group of blocks including the encoded service data and the encoded signaling information, wherein the group of blocks 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 service data; and

transmitting the broadcast signal including the formed group of blocks, wherein the formed group of blocks further includes fast service acquisition information for accessing a service of the service data,

wherein the broadcast signal further includes service type information identifying a type of the service of the service data and hidden information indicating whether the service of the service data is hidden or not.

2. The method of claim 1, wherein the signaling information includes information of the group of blocks.

3. The method of claim 1, wherein the broadcast signal further includes service component information of the service.

4. The method of claim 1, wherein the signaling information includes code rate information for the encoding.

5. An apparatus for transmitting a broadcast signal, the apparatus comprising:

an encoder configured to encode service data for FEC (Forward Error Correction);

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

a formatter configured to form a group of blocks including the encoded service data and the encoded signaling information, wherein the group of blocks 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 service data; and

a transmitter configured to transmit the broadcast signal including the formed group of blocks, wherein the formed group of blocks further includes fast service acquisition information for accessing a service of the service data,

wherein the broadcast signal further includes service type information identifying a type of the service of the service data and hidden information indicating whether the service of the service data is hidden or not.

6. The apparatus of claim 5, wherein the signaling information includes information of the group of blocks.

7. The apparatus of claim 5, wherein the broadcast signal further includes service component information of the service.

8. The apparatus of claim 5, wherein the signaling information includes code rate information for the encoded service data.
