Digital broadcasting system and method of processing data in digital broadcasting system
First Claim
1. A method of processing data for a receiver, the method comprising:
- receiving and demodulating a broadcast signal comprising fast information channel (FIC) data including cross layer information for mobile service acquisition, transmission parameter channel (TPC) data including FIC version information for identifying an update of the FIC data, and a Reed-Solomon (RS) frame including mobile service data;
forming an ensemble identified by an ensemble identifier from the demodulated RS frame and extracting a service map table (SMT) from the ensemble, the SMT being encapsulated with a user datagram protocol (UDP) header and an internet protocol (IP) header, and the SMT having a well-known target IP address and a well-known target UDP port number; and
accessing to an IP datagram of desired mobile service data in the ensemble according to mobile service acquisition information and IP access information of each mobile service included in the extracted SMT.

Abstract
A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcasting system includes a baseband processor, a management processor, and a presentation processor. The baseband processor receives broadcast signals including mobile service data and main service data. Herein, the mobile service data may configure a RS frame, which includes mobile service data and table information describing channel configuration information and IP access information of an ensemble level corresponding to the RS frame. The table information is encapsulated to a UDP/IP header. The management processor processes table information from the RS frame to acquire channel configuration information and IP access information of an ensemble level, and accesses mobile service data requested to be received from the RS frame, based upon the acquired information. The presentation processor decodes the accessed mobile service data and outputs the decoded data to a display screen and/or a speaker.
