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 transmitter, the method comprising:
encapsulating one or more first data packets that carry broadcast service data for a broadcast service into a second data packet having a second data packet header and a second data packet payload, the second data packet header including information indicating a number of first data packets included in the second data packet payload of the second data packet;
encoding data of the second data packet;
encoding physical layer parameters; and
transmitting a transmission frame including the encoded data, the encoded physical layer parameters and signaling information that is carried in a payload of IP (Internet Protocol) packets with a well-known address and a well-known port number,
wherein the signaling information includes information indicating whether the broadcast service is hidden and an address and port number for the broadcast service data.

2. The method of claim 1 , wherein the signaling information further includes identification information identifying 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 , wherein the physical layer parameters include information related to the transmission frame.

5. The method of claim 1 , wherein:
the broadcast service data are encrypted; and
the signaling information further includes encryption information of the broadcast service data.

6. A broadcast transmitter for processing data, the broadcast transmitter comprising:
a packet generator to encapsulate one or more first data packets that carry broadcast service data for a broadcast service into a second data packet having a second data packet header and a second data packet payload, the second data packet header including information indicating a number of first data packets included in the second data packet payload of the second data packet;
a first encoder to encode data of the second data packet;
a second encoder to encode physical layer parameters; and
a transmitter to transmit a transmission frame including the encoded data, the encoded physical layer parameters and signaling information that is carried in a payload of IP packets with a well-known address and a well-known port number,
wherein the signaling information includes information indicating whether the broadcast service is hidden and an address and a port number for the broadcast service data.

7. The broadcast transmitter of claim 6 , wherein the signaling information further includes identification information identifying the broadcast service.

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

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

10. The broadcast transmitter of claim 6 , wherein:
the broadcast service data are encrypted; and
the signaling information further includes encryption information of the broadcast service data.
