Digital broadcasting system and data processing method
First Claim
1. A receiving system comprising:
- a tuner for receiving a broadcast signal having data groups, wherein each of the data groups includes mobile service data, known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes binding information between a service of the mobile service data and an ensemble, wherein the ensemble carries a signaling information table and includes either a primary ensemble or a secondary ensemble;
a demodulator for demodulating the received broadcast signal;
a first decoder for decoding the FIC data and the TPC data from the demodulated broadcast signal; and
a second decoder for decoding a Reed Solomon (RS) frame including the mobile service data and the signaling information table from the demodulated broadcast signal,wherein the RS frame includes a plurality of transport packets,wherein each of the plurality of transport packets includes a header and a payload,wherein the payload includes at least one Internet protocol (IP) datagram,wherein the header includes a pointer field indicating a start position of a new IP datagram in the payload,wherein the RS frame belongs to either the primary ensemble or the secondary ensemble,wherein the FIC data includes an ensemble identifier to identify the ensemble, andwherein the TPC data includes FIC version information for identifying an update of the FIC data.

Abstract
A digital broadcasting system and method of processing data therein are disclosed. The present invention includes a baseband processor unit receiving a broadcast signal including mobile service data and main service data, wherein the mobile service data can configure an RS frame and wherein the RS frame includes at least one of the mobile service data and a notification message and at least one of a first signaling information describing signaling information of a virtual channel for transmitting the mobile service data and a second signaling information describing signaling information on a notification channel for transmitting the notification message, a management processor unit accessing the notification message by parsing the second signaling information from the RS frame, the management processor unit processing the accessed notification message, the management processor unit storing the processed notification message in a storage device, and a presentation processor unit outputting the processes notification message to an output device.

10. A method of processing broadcast data in a receiving system, the method comprising:
-
receiving, by a tuner, a broadcast signal having data groups, wherein each of the data groups includes mobile service data, known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes binding information between a service of the mobile service data and an ensemble, wherein the ensemble carries a signaling information table and includes either a primary ensemble or a secondary ensemble; demodulating, by a demodulator, the received broadcast signal; decoding, by a first decoder, the FIC data and the TPC data from the demodulated broadcast signal; and decoding, by a second decoder, a Reed Solomon (RS) frame including the mobile service data and the signaling information table from the demodulated broadcast signal, wherein the RS frame includes a plurality of transport packets, wherein each of the plurality of transport packets includes a header and a payload, wherein the payload includes at least one Internet protocol (IP) datagram, wherein the header includes a pointer field indicating a start position of a new IP datagram in the payload, wherein the RS frame belongs to either the primary ensemble or the secondary ensemble, wherein the FIC data includes an ensemble identifier to identify the ensemble, and wherein the TPC data includes FIC version information for identifying an update of the FIC data. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
