摘要:
The present invention discloses a receiving system and a method of processing data to receiving and processing mobile service data. The receiving system may include a signal receiving unit, a demodulating unit, a data processor, and a middleware engine. The signal receiving unit receives a broadcasting signal, which includes IP packets, payload of the IP packets including a DSM-CC module data part and a DSM-CC header, the DSM-CC module data part including a plurality of DSM-CC objects, and the DSM-CC header including identification information for identifying the DSM-CC module. The demodulating unit demodulates the received broadcasting signal including IP packets. The data processor extracts a plurality of DSM-CC objects of a corresponding payload with reference to DSM-CC header information of the IP packets demodulated by the demodulating unit and configuring a DSM-CC module, which includes identification information and the extracted DSM-CC objects. The middleware engine provides a data broadcasting service by driving application corresponding to the DSM-CC module.
摘要:
A digital broadcasting system and a method of processing data are disclosed, which are robust to error when mobile service data are transmitted. To this end, additional encoding is performed for the mobile service data, whereby it is possible to strongly cope with fast channel change while giving robustness to the mobile service data.
摘要:
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 method of processing broadcast data in a broadcast transmitter includes performing Reed-Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data to build at least one RS frame including the mobile service data and dividing the at least one RS frame into a plurality of portions; dividing each of the plurality of portions into several Serial Concatenated Convolutional Code (SCCC) blocks according to SCCC block mode information, encoding data in the SCCC blocks, and mapping the SCCC blocks including the encoded data to data blocks according to the SCCC block mode information; encoding signaling data including fast information channel (FIC) data and transmission parameter channel (TPC) data; and modulating a broadcast signal including data in the data blocks and the encoded signaling data.
摘要:
The present invention is directed to a digital broadcast system and a data processing method. A broadcast signal in which mobile service data and main service data are multiplexed is transmitted and received. Then, in a broadcasting receiver, the program table information including information about a service or a program of an ensemble is parsed according to an identifier of the ensemble in which the mobile service data are multiplexed, in the received broadcast signal. And a mobile service is outputted by using the mobile service data and the parsed program table information.
