摘要:
A transmitting system, a receiving system, and a method of processing a broadcast signal are disclosed herein. The receiving system include a tuner, a demodulator, a block decoder, an RS frame decoder, and a service manager. The tuner receives a broadcast signal. Herein the broadcast signal includes mobile service data, a service map table signaling access information of the mobile service data, and a plurality of known data sequences. The mobile service data and the service map table are packetized to an RS frame. The demodulator demodulates the received broadcast signal. The block decoder turbo-decodes the mobile service data and the service map table included in the demodulated broadcast signal in block units. The RS frame decoder forming an RS frame including the turbo-decoded mobile service data and service map table, performs primary first cyclic redundancy check (CRC)-decoding and RS-decoding, and performs secondary CRC-decoding on the primarily CRC-decoded and RS-decoded RS frame. The service manager acquires source IP address information of IP datagrams of the RS frame-decoded mobile service data from the service map table.

A digital broadcast receiver and a control method thereof are disclosed. The control method of the digital broadcast receiver includes receiving a broadcast signal into which mobile service data and main service data are multiplexed, extracting transmission parameter channel (TPC) signaling information and fast information channel (FIC) signaling information from a data group in the received mobile service data, acquiring a program table describing virtual channel information and a service of an ensemble, which is a virtual channel group of the received mobile service data, using the extracted FIC signaling information, selectively detecting a first message descriptor mapped with time information or a second message descriptor not mapped with time information, using the acquired program table, performing a control operation to display a message defined in the detected message descriptor.

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 method of processing additional information related to an announced service or content in a Non-Real Time (NRT) service and the broadcast receiver are disclosed herein. A method of providing a Non-Real Time (NRT) service in a broadcasting receiver includes receiving a service map table (SMT) and a first descriptor through a service signaling channel, identifying an image identifier and an image type of an image for an NRT service based upon the first descriptor, receiving the image via a flute session and displaying the image when corresponding service is played, wherein the image is logo or icon data for the NRT service. The method may further include connecting a service signaling channel, parsing the received SMT and the first descriptor, determining whether a service is the NRT service based upon the parsed SMT and storing the received image.
