  • Publication number: 20090228765
    Abstract: A transmitting system and a method of processing data are disclosed herein. The transmitting system includes a service multiplexer and at least one transmitter located in a remote position from the service multiplexer. The service multiplexer transmits an operations and maintenance (OM) packet and mobile service data. Herein, the OM packet describes a transmission parameter including a transmission frame information, a Reed-Solomon (RS) frame information, and a serial concatenated convolution code (SCCC) information of the mobile service data. Each transmitter performs error correction encoding and block encoding on the mobile service data based upon the transmission parameter within the OM packet transmitted from the service multiplexer, thereby transmitting the processed mobile service data to a receiving system.

  • Publication number: 20090228764
    Abstract: A transmitting system and a method for processing data are disclosed herein. The transmitting system includes a service multiplexer and at least one transmitter located in a remote position from the service multiplexer. Herein, the service multiplexer generates an RS frame having the size of N(row)xl87(column) bytes including at least one type of mobile service data, packetizes the RS frame into a plurality of mobile service data packets, and multiplexes the packetized mobile service data packets with a main service data packet at a predetermined data rate, thereby transmitting the multiplexed data packets. Herein, each mobile service data packet is configured of a TS header and a data region, and the data region is configured of at least one of a payload region and an adaptation field region.

  • Publication number: 20090207908
    Abstract: A digital broadcast system and a data processing method are disclosed. A data processing method of a digital broadcast transmission system includes delaying a reference time of a program clock reference (PCR) based on a size of mobile service data, when processing a broadcasting signal including main service data and the mobile service data, verifying a transport stream system target decoder (T-STD) model based on the PCR of the delayed reference time, and storing a packet of the main service data in an auxiliary buffer, when overflow of a buffer in the T-STD model is estimated as the verification result of the T-STD model.

  • Publication number: 20090150916
    Abstract: A digital broadcasting system and a data processing method are disclosed. A data processing method of a digital broadcasting receiver comprises receiving a mobile/handheld (MH) broadcasting signal including mobile service data and main service data; generating a RS (Reed-Solomon) frame from the received MH broadcasting signal; extracting control data from the RS frame, the control data including charge adjustment information required to use a service provided by at least one service provider, the service being encrypted; determining whether the service is available, by comparing the extracted charge adjustment information with balance information written in the smart card; controlling the second RS frame using the control data so that an encrypted service of the second RS frame is decrypted, if the service is available; and mapping the extracted charge adjustment information with a corresponding service provider and storing the information.

  • Publication number: 20090150932
    Abstract: A digital broadcasting system and a data processing method are disclosed. A data processing method of a digital broadcasting receiver comprises receiving a mobile/handheld (MH) broadcasting signal including mobile service data and main service data; generating RS(Reed-Solomon) frames from the received MH broadcasting signal; extracting ESG (electronic service guide) data from the generated RS frame; extracting SDP (session description protocol) data from the extracted ESG data; checking a port number corresponding to subtitle having reference information, among the extracted SDP data; and controlling the subtitle having reference information using the checked port number so that the subtitle having reference information is displayed.

  • Publication number: 20090097429
    Abstract: A digital broadcasting system and a method for controlling the same are disclosed. A method for controlling a digital broadcast receiving system includes the steps of receiving a broadcast signal having mobile service data and main service data multiplexed therein, extracting transmission parameter channel (TPC) signaling information and fast information channel (FIC) signaling information from a data group within the received mobile service data, by using the extracted fast information channel (FIC) signaling information, acquiring a program table describing virtual channel information and service of an ensemble, the ensemble being a virtual channel group of the received mobile service data, by using the acquired program table, detecting a descriptor defining basic information required for accessing the received service, and, by using the detected descriptor, controlling the receiving system to enable access to the corresponding service.

  • Publication number: 20090080572
    Abstract: A digital broadcast receiver and a control method thereof are disclosed. The control method includes receiving a broadcast signal into which mobile service data and main service data are multiplexed, extracting TPC signaling information and 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, using the extracted FIC signaling information, the ensemble being a virtual channel group of the received mobile service data, detecting a conditional access descriptor indicating whether the mobile service data was encrypted, using the acquired program table, and controlling such that the encrypted mobile service data is decrypted, using information of the detected conditional access descriptor.
