Abstract

Methods and apparatus for transmitting and receiving broadcast signals are provided. The method for transmitting a broadcast signal includes encoding mobile data for forward error correction (FEC), encoding signaling data, forming data groups including the encoded mobile data and the encoded signaling data and transmitting a signal frame that includes the data groups.

First claim

What is claimed:

1 . A method of processing broadcast data in a digital transmitter, the method comprising:
generating a broadcast signal including a frame, wherein the frame includes first signaling data, second signaling data, third signaling data and service data for a service, wherein the first signaling data includes first information for identifying the service and second information for indicating whether the service is hidden or not, wherein a service signaling channel carries the second signaling data, and the second signaling data is used to provide service acquisition information for the service, wherein the service signaling channel is a dedicated channel identified by a pre-assigned value, wherein the second signaling data includes third information for identifying the service and fourth information for indicating whether the service is active or inactive, wherein the frame is composed of multiple sub-frames, wherein the multiple sub-frames are concatenated in the frame, and wherein the third signaling data includes fifth information related to the first signaling data and sixth information related to the multiple sub-frames; and transmitting the broadcast signal.

2 . The method of claim 1 , wherein the first information included in the first signaling data and the third information included in the second signaling data have a same value.

3 . The method of claim 1 , wherein the first signaling data further includes seventh information for indicating whether one or more components needed for presentation of the service are protected.

4 . The method of claim 3 , wherein the second signaling data further includes eighth information for indicating a name of the service.

5 . The method of claim 1 , wherein the service data corresponds to an audio or video component that makes up the service.

6 . A digital transmitter for processing broadcast data, the digital transmitter comprising:
a processor configured to generate a broadcast signal including a frame, wherein the frame includes first signaling data, second signaling data, third signaling data and service data for a service, wherein the first signaling data includes first information for identifying the service and second information for indicating whether the service is hidden or not, wherein a service signaling channel carries the second signaling data, and the second signaling data is used to provide service acquisition information for the service, wherein the service signaling channel is a dedicated channel identified by a pre-assigned value, wherein the second signaling data includes third information for identifying the service and fourth information for indicating whether the service is active or inactive, wherein the frame is composed of multiple sub-frames, wherein the multiple sub-frames are concatenated in the frame, and wherein the third signaling data includes fifth information related to the first signaling data and sixth information related to the multiple sub-frames; and a transmitter configured to transmit the broadcast signal.

7 . The digital transmitter of claim 6 , wherein the first information included in the first signaling data and the third information included in the second signaling data have a same value.

8 . The digital transmitter of claim 6 , wherein the first signaling data further includes seventh information for indicating whether one or more components needed for presentation of the service are protected.

9 . The digital transmitter of claim 8 , wherein the second signaling data further includes eighth information for indicating a name of the service.

10 . The digital transmitter of claim 6 , wherein the service data corresponds to an audio or video component that makes up the service.

11 . A method of processing broadcast data in a digital receiver, the method comprising:
receiving a broadcast signal including a frame, the frame including first signaling data, second signaling data, third signaling data and service data for a service wherein the first signaling data includes first information for identifying the service and second information for indicating whether the service is hidden or not, wherein a service signaling channel carries the second signaling data, and the second signaling data is used to provide service acquisition information for the service, wherein the service signaling channel is a dedicated channel identified by a pre-assigned value, wherein the second signaling data includes third information for identifying the service and fourth information for indicating whether the service is active or inactive, wherein the frame is composed of multiple sub-frames, wherein the multiple sub-frames are concatenated in the frame, and wherein the third signaling data includes fifth information related to the first signaling data and sixth information related to the multiple sub-frames; and processing the service data based on the first signaling data, the second signaling data and the third signaling data.

12 . The method of claim 11 , wherein the first information included in the first signaling data and the third information included in the second signaling data have a same value.

13 . The method of claim 11 , wherein the first signaling data further includes seventh information for indicating whether one or more components needed for presentation of the service are protected.

14 . The method of claim 13 , wherein the second signaling data further includes eighth information for indicating a name of the service.

15 . The method of claim 11 , wherein the service data corresponds to an audio or video component that makes up the service.

16 . A digital receiver for processing broadcast data, the digital receiver comprising:
a receiver configured to receive a broadcast signal including a frame, the frame including first signaling data, second signaling data, third signaling data and service data for a service, wherein the first signaling data includes first information for identifying the service and second information for indicating whether the service is hidden or not, wherein a service signaling channel carries the second signaling data, and the second signaling data is used to provide service acquisition information for the service, wherein the service signaling channel is a dedicated channel identified by a pre-assigned value, wherein the second signaling data includes third information for identifying the service and fourth information for indicating whether the service is active or inactive, wherein the frame is composed of multiple sub-frames, wherein the multiple sub-frames are concatenated in the frame, and wherein the third signaling data includes fifth information related to the first signaling data and sixth information related to the multiple sub-frames; and a processor configured to process the service data based on the first signaling data, the second signaling data and third signaling data.

17 . The digital receiver of claim 16 , wherein the first information included in the first signaling data and the third information included in the second signaling data have a same value.

18 . The digital receiver of claim 16 , wherein the first signaling data further includes seventh information for indicating whether one or more components needed for presentation of the service are protected.

19 . The digital receiver of claim 18 , wherein the second signaling data further includes eighth information for indicating a name of the service.
