Abstract

A method of processing broadcast data includes: performing RS encoding and CRC encoding on mobile service data to generate an RS frame belonging to an ensemble including a signaling information table including access information of the mobile service data and identification information for identifying a stream where keys to decrypt the mobile service data are obtained; mapping a portion of data in the RS frame to a group including known data sequences, FIC data, and TPC data, wherein the FIC data includes information for rapid mobile service acquisition, and the TPC data includes FIC version information for indicating an update of the FIC data; and transmitting a broadcast signal including the group. The group further includes data blocks. First, fourth, fifth and sixth known data sequences are inserted into third, fifth, sixth and seventh data blocks, respectively. Second and third known data sequences are inserted into a fourth data block.

First claim

What is claimed is:

1 . A method of processing data in a broadcast receiver, the method comprising:
receiving a broadcast signal including a transmission frame, the transmission frame including broadcast service data for a broadcast service, physical layer parameters, and signaling information for signaling the broadcast service; demodulating the received broadcast signal; decoding the physical layer parameters in the transmission frame of the demodulated broadcast signal; and decoding the broadcast service data in the transmission frame of the demodulated broadcast signal, wherein the signaling information includes information indicating whether the broadcast service is hidden, channel information of the broadcast service, and identification information identifying the broadcast service, wherein the decoded broadcast service data are included in one or more first data packets, wherein the one or more first data packets are included in a data packet payload of a second data packet, wherein a data packet header of the second data packet includes information indicating a number of first data packets included in the data packet payload, and wherein the signaling information is included in a payload of IP (Internet Protocol) packets with a known address and a known port number.

2 . The method of claim 1 , wherein the signaling information further includes an address and port number related to the broadcast service.

3 . The method of claim 1 , wherein the signaling information further includes type information identifying a type of the broadcast service.

4 . The method of claim 1 , further comprising:
decrypting the broadcast service data, wherein the signaling information further includes encryption information of the broadcast service data.

5 . The method of claim 1 , wherein the physical layer parameters include information related to the transmission frame.

6 . A broadcast receiver for processing data, the broadcast receiver comprising:
a tuner to receive a broadcast signal including a transmission frame, the transmission frame including broadcast service data for a broadcast service, physical layer parameters, and signaling information for signaling the broadcast service; a demodulator to demodulate the received broadcast signal; a first decoder to decode the physical layer parameters in the transmission frame of the demodulated broadcast signal; and a second decoder to decode the broadcast service data in the transmission frame of the demodulated broadcast signal, wherein the signaling information includes information indicating whether the broadcast service is hidden, channel information of the broadcast service, and identification information identifying the broadcast service, wherein the decoded broadcast service data are included in one or more first data packets, wherein the one or more first data packets are included in a data packet payload of a second data packet, wherein a data packet header of the second data packet includes information indicating a number of first data packets included in the data packet payload, and wherein the signaling information is included in a payload of IP (Internet Protocol) packets with a known address and a known port number.

7 . The broadcast receiver of claim 6 , wherein the signaling information further includes an address and port number related to the broadcast service.

8 . The broadcast receiver of claim 6 , wherein the signaling information further includes type information identifying a type of the broadcast service.

9 . The broadcast receiver of claim 6 , further comprising:
a handler to decrypt the broadcast service data, wherein the signaling information further includes encryption information of the broadcast service data.

10 . The broadcast receiver of claim 6 , wherein the physical layer parameters include information related to the transmission frame.
