A digital broadcast system having storing resistance to errors generated during the transmission of mobile service data, and a data processing method are disclosed. The digital broadcast system additionally encodes mobile service data. As a result, the mobile service data has strong resistance to a channel variation and noise, and at the same time the system can quickly cope with the channel variation.

A digital broadcasting system and a data processing method are disclosed. The receiving system of the digital broadcasting system includes a receiving unit, a main service data processor, a mobile service data processor, a controller, and an output controller. The receiving unit receives mobile service data and main service data including the same A/V broadcast signal and receives retransmission channel information. The main service data processor demodulates and error-corrects the received main service data and temporarily stores the processed data. The mobile service data processor demodulates and error-corrects the received mobile service data and temporarily stores the processed data. The controller generates and outputs a control signal based upon the received retransmission channel information and a receiving environment of the receiving system. And, the output controller selects any one of the A/V broadcast signal for the main service and the A/V broadcast signal for the mobile service based upon the control signal of the controller.

A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcasting system comprises a baseband processor, a management processor and a presentation processor. The baseband processor receives a broadcast signal including mobile service data and main service data, wherein the mobile service data configure a Reed-Solomon (RS) frame. The RS frame includes at least one of the mobile service data and notification messages. The notification messages are packetized in accordance with any one of a first transport protocol and a second transport protocol. The management processor decodes the notification messages from the RS frame in accordance with any one of the first transport protocol and the second transport protocol. The presentation processor directly outputs the decoded notification messages to an output unit in accordance with a channel which transmits the decoded notification messages, or outputs the decoded notification messages to the output unit only if a user selects the notification messages.

A digital broadcasting system and a data processing method are disclosed. A receiver receives a broadcast signal including mobile service data and main service data. A known data detector detects known data from the broadcast signal. An equalizer performs channel equalization on the mobile service data received by means of the detected known data. An RS frame decoder acquires an RS frame from the channel-equalized mobile service data. A management processor extracts a Generic Stream Encapsulation (GSE) packet from a GSE Base Band (BB) constructing one row of the RS frame, and calculates an IP datagram from the extracted GSE packet. A presentation processor displays broadcast data using data contained in the calculated IP datagram.
