A method of processing a web service in a Non-Real Time (NRT) service and the broadcast receiver are disclosed herein. A method of providing an NRT service in a broadcasting receiver may include receiving first signaling information, identifying whether a service type of an NRT service is a web service based upon the first signaling information, identifying a web page type and a web page version of the NRT service and browsing the NRT service. The method may further include connecting a service signaling channel, parsing the received first signaling information, determining whether the NRT service is supported in the broadcasting receiver and consuming the web contents of the NRT service. The NRT service may include at least one of a fixed NRT service and a mobile NRT service. The first signaling information may be a data casting description table (DDT) if the NRT service is the fixed NRT service. The first signaling information may be a service map table (SMT) if the NRT service is the mobile NRT service. The DDT may include a first field identifying the NRT service and a second field identifying a type of the NRT service. The type of the web service may include at least one of a web document of text HTML and a web document of CE-HTML. The third field and the fourth field may be valid if the type of the received service is the web service based upon the second field.

Method for processing a web service in an NRT service and a broadcast receiver

The present invention provides a method of processing data. The method of processing data includes receiving a broadcasting signal where mobile service data are multiplexed with main service data, extracting transmission-parameter-channel signaling information and fast-information-channel signaling information from a data group within the received mobile service data; obtaining first program table information describing virtual channel information of an ensemble and a service provided by the ensemble using the fast-information-channel signaling information, the ensemble the ensemble corresponding to a virtual channel group of the received mobile service data, obtaining information indicating that second program table information, which describes an additional service provided by the ensemble, is included in the ensemble and parsing the second program table information according to the obtained information; and providing the additional service by using the second program table information.

Digital broadcasting system and method of processing data in digital broadcasting system

The present invention provides a data processing method that includes receiving a broadcasting signal in which mobile service data are multiplexed with main service data, extracting transmission-parameter-channel signaling information and fast-information-channel (FIC) signaling information from a data group within the received mobile service data, parsing first program table information describing virtual channel information of an ensemble and a service provided by the ensemble using the FIC signaling information, the ensemble corresponding to a virtual channel group of the received mobile service data, obtaining information from the first program table information, the information representing that second program table information including a descriptor describing event information of the mobile service data is received, parsing the second program table information, storing the event information and displaying service guide information including the event information.

A digital broadcasting system and a data processing method are disclosed. The method includes, receiving a broadcast signal in which mobile service data and main service data are multiplexed, extracting transmission parameter signaling information and fast-information-channel signaling information from a data group contained in the received mobile service data, parsing first program table information, which describes virtual channel information and a service of an ensemble acting as a virtual channel group of the received mobile service data, using the fast-information-channel signaling information, parsing second program table information including a data chunk acting as data-broadcasting contents of the mobile service data, and providing a data broadcasting service using the data broadcasting contents of the parsed second program table information.

A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcast system includes a mobile service data processor, a main service data processor, a controller, and a display module. The mobile service data processor receives mobile service data through a mobile service data path. Herein, the mobile service data configures an RS frame, and the RS frame includes mobile service data including a mobile A/V broadcast signal and at least one channel configuration information on the mobile service data. The main service data processor receives main service data through a main service data path. Herein, the main service data includes a main A/V broadcast signal and a program guide information of the main A/V broadcast. The controller extracts a link information for the program guide service of the mobile A/V broadcast signal from the channel configuration information, and acquires a corresponding program guide information from the main service data processor by using the extracted link information. And, the display module outputs the program guide information acquired from the controller to a display screen.

Digital broadcasting system and method of processing data in the digital broadcasting system

A digital broadcasting system and a data processing method are disclosed. The digital broadcast receiving system includes 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. Herein, the mobile service data configure a Reed-Solomon (RS) frame, and the RS frame includes mobile service data and at least one channel configuration information on the mobile service data.
