Abstract

According to one embodiment, a method of processing broadcast data in a broadcast transmitter includes: encoding the broadcast data for broadcast service; encoding signaling information for signaling the broadcast data; assigning the encoded broadcast data and the encoded signaling information into a signal frame; and transmitting a broadcast signal including the signal frame. The broadcast signal further includes a signaling table having access information of the broadcast data. The signaling table includes service id information for identifying the broadcast service and component information for indicating a number of components in the broadcast service.

Claims

1. A method of processing broadcast data in a broadcast transmitter, the method comprising:

encoding the broadcast data for broadcast service;

encoding signaling data, wherein the signaling data includes transmission parameters of the encoded broadcast data;

assigning the encoded broadcast data and the encoded signaling data into a signal frame; and

transmitting a broadcast signal including the signal frame,

wherein the signal frame includes a part for fast service acquisition for obtaining a signaling table having access information of the broadcast data, wherein the signaling table includes an identifier for the broadcast signal.

2. The method of claim 1, wherein the signaling table further includes service number information indicating a number of broadcast services.

3. The method of claim 1, wherein the signaling table includes service id information for identifying the broadcast service and service type information for identifying type of the broadcast service.

4. The method of claim 1, wherein the signaling table includes table id information for identifying the signaling table and component information indicating a number of components in the broadcast service.

5. The method of claim 1, wherein the signaling table further includes channel numbers of the broadcast service.

6. An apparatus of processing broadcast data in a broadcast transmitter, the apparatus comprising:

an encoder to encode the broadcast data for broadcast service;

a signaling encoder to encode signaling data, wherein the signaling data;

includes transmission parameters of the encoded broadcast data;

a transmitter to assign the encoded broadcast data and the encoded signaling data into a signal frame and transmitting a broadcast signal including the signal frame,

wherein the signal frame includes a part for fast service acquisition for obtaining a signaling table having access information of the broadcast data, wherein the signaling table includes an identifier for the broadcast signal.

7. The apparatus of claim 6, wherein the signaling table further includes service number information indicating a number of broadcast services.

8. The apparatus of claim 6, wherein the signaling table includes service id information for identifying the broadcast service and service type information for identifying type of the broadcast service.

9. The apparatus of claim 6, wherein the signaling table includes table id information for identifying the signaling table and component information for indicating a number of components in the broadcast service.

10. The apparatus of claim 6, wherein the signaling table further includes channel numbers of the broadcast service.
