Abstract

A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcasting system includes a receiving unit, an SI handler, and a decoding unit. The receiving unit receives broadcast signals including mobile service data and main service data. The mobile service data configure a data group, and the data group includes a signaling information region in some of a plurality of data regions. The signaling information region may include TPC signaling data and FIC signaling data. The SI handler acquires channel configuration information of the mobile service data from the broadcast signal using pre-decided IP access information, and extracts encoding format information for each IP stream component within a corresponding virtual channel service RTP-packetized and received from the acquired channel configuration information. The decoding unit decodes the mobile service data of the corresponding IP stream component based upon the extracted encoding format information.

First claim

What is claimed is:

1. A method for receiving a broadcast signal, the method comprising:
receiving the broadcast signal, the broadcast signal including a data unit;
demodulating the broadcast signal;
decoding first signaling data from the demodulated broadcast signal, the first signaling data including fast service acquisition information;
decoding multiplexed data from the demodulated broadcast signal, wherein the multiplexed data includes second signaling data and service data, and the second signaling data is carried in a payload of at least user datagram protocol (UDP) or Internet Protocol (IP) packets,
wherein the second signaling data includes:
service identifier information that uniquely identifies a service of the service data;
destination IP address information for receiving the service; and
a destination UDP port number for receiving the service;
decoding the service data based on the decoded second signaling data.

2. The method of claim 1 , wherein the data unit includes a first region and a second region, wherein the first region includes first known data and signaling information, and the second region includes second known data and broadcast data.
