A digital broadcast receiver and a control method thereof are provided. The digital broadcast receiver includes a reception unit for receiving a broadcast signal in which mobile service data and main service data are multiplexed, an extractor for extracting transmission parameter channel signaling information and fast information channel signaling information from a data group in the received mobile service data, an acquirer for acquiring a program table describing virtual channel information and a service of an ensemble by using the extracted fast information channel signaling information, the ensemble being a virtual channel group of the received mobile service data, a detector for detecting a descriptor defining Internet access information corresponding to the mobile service data by using the acquired program table, and a controller for controlling the Internet access information of the detected descriptor and the mobile service data to be displayed.

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

A digital broadcast receiver and a control method thereof are disclosed. The digital broadcast receiver includes a reception unit for receiving a broadcast signal which mobile service data and main service data are multiplexed, an extractor for extracting transmission parameter channel signaling information and fast information channel signaling information from a data group in the received mobile service data, an acquirer for acquiring a program table describing virtual channel information and a service of an ensemble by using the extracted fast information channel signaling information, the ensemble being a virtual channel group of the received mobile service data, a detector for detecting a descriptor defining Internet access information corresponding to the mobile service data by using the acquired program table, and a controller for controlling such that the Internet access information of the detected descriptor and the mobile service data are displayed.

The present invention provides a data processing method 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, parsing 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 corresponding to a virtual channel group of the received mobile service data, obtaining permission information of broadcasting contents included in the mobile service data from the first program table information and controlling the contents included in the mobile service data in accordance with the permission information.

A digital broadcast receiver and a control method thereof are disclosed. The digital broadcast receiver includes a reception unit for receiving a broadcast signal which mobile service data and main service data are multiplexed, an extractor for extracting transmission parameter channel signaling information and fast information channel signaling information from a data group in the received mobile service data, an acquirer for acquiring a program table describing virtual channel information and a service of an ensemble by using the extracted fast information channel signaling information, the ensemble being a virtual channel group of the received mobile service data, a detector for detecting a descriptor defining a destination telephone number of a message service by using the acquired program table, and a controller for controlling such that the destination telephone number of the message service of the detected descriptor and the mobile service data are displayed.

A digital broadcast receiver and a control method thereof are disclosed. The digital broadcast receiver includes a reception unit for receiving a broadcast signal which mobile service data and main service data are multiplexed, an extractor for extracting transmission parameter channel signaling information and fast information channel signaling information from a data group in the received mobile service data, an acquirer for acquiring a program table describing virtual channel information and a service of an ensemble by using the extracted fast information channel signaling information, the ensemble being a virtual channel group of the received mobile service data, a detector for detecting a descriptor defining a telephone number system corresponding to the mobile service data by using the acquired program table, and a controller for controlling such that a telephone number of the telephone number system of the detected descriptor and the mobile service data are displayed.

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.
