Abstract

A digital broadcast receiving system and a method for controlling the same are disclosed. The method 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, wherein the FIC signaling information includes a current/next (C/N) indicator, and wherein the TPC signaling information includes FIC version information, and detecting ensemble configuration information of a current MH frame.

Claims

1. A method of processing data for a receiver, the method comprising:

receiving and demodulating a broadcast signal including mobile service data and main service data;

extracting a fast information channel (FIC) and a transmission parameter channel (TPC) from the broadcast signal, the FIC including a current and next (C/N) indicator field and the TPC including identification information for identifying an update of the FIC; and

determining whether the FIC is applicable to a current mobile and handheld (M/H) frame or a next mobile and handheld (M/H) frame.

2. The method of claim 1, wherein the FIC further includes cross layer information for mobile service acquisition.

3. The method of claim 1, wherein the FIC is applicable to the next M/H frame when the C/N indicator is set to 1.

4. The method of claim 1, wherein the FIC is applicable to the current M/H frame when the C/N indicator is not set to 1.

5. The method of claim 1, wherein the identification information indicates FIC version information for identifying the update of the FIC.

6. The method of claim 1, the FIC further includes error indication information indicating whether the FIC contains an error.

7. The method of claim 1, wherein the FIC is segmented into a plurality of FIC segments, each of the plurality of FIC segments comprising a 2 byte header including FIC type information and a 35 byte payload including channel binding information.

8. The method of claim 7, wherein the payload further includes an ensemble identifier identifying an ensemble and mobile service information included in the ensemble.

9. The method of claim 1, further comprising detecting known data from the broadcast signal.

10. The method of claim 2, further comprising channel-equalizing the mobile service data included in the demodulated broadcast signal using the detected known data.

11. A receiver comprising:

a receiving unit configured to receive and demodulate a broadcast signal including mobile service data and main service data;

a first handler configured to extract a fast information channel (FIC) and a transmission parameter channel (TPC) from the broadcast signal, the FIC including a current and next (C/N) indicator field and the TPC including identification information for identifying an update of the FIC; and

a second handler configured to determine whether the FIC is applicable to a current mobile and handheld (M/H) frame or a next mobile and handheld (M/H) frame.

12. The receiver of claim 11, wherein the FIC further includes cross layer information for mobile service acquisition.

13. The receiver of claim 11, wherein the second handler applies the FIC to the next M/H frame when the C/N indicator is set to 1.

14. The receiver of claim 11, the second handler applies the FIC to the current M/H frame when the C/N indicator is not set to 1.

15. The receiver of claim 11, wherein the identification information indicates FIC version information for identifying the update of the FIC.

16. The receiver of claim 11, the FIC further includes error indication information indicating whether the FIC contains an error.

17. The receiver of claim 11, wherein the FIC is segmented into a plurality of FIC segments, each of the plurality of FIC segments comprising a 2 byte header including FIC type information and a 35 byte payload including channel binding information.

18. The receiver of claim 17, wherein the payload further includes an ensemble identifier identifying an ensemble and mobile service information included in the ensemble.

19. The receiver of claim 11, further comprising a known data detector configured to detect known data from the broadcast signal.

20. The receiver of claim 19, further comprising a channel equalizer configured to channel-equalize the mobile service data included in the demodulated broadcast signal using the detected known data.
