DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA IN DIGITAL BROADCASTING SYSTEM

摘要

A digital broadcasting system and a method of processing data in the digital broadcasting system are provided to supply information with regard to an encoding parameter of each IP stream component of a corresponding virtual channel through an SMT. A receiver(120) receives a broadcast signal including mobile service data and main service data. The mobile service data can comprise a data group. The data group includes a signaling information area within a partial area among a plurality of areas. The signaling information area includes transmission parameter channel(TPC) signaling and fast information channel(FIC) signaling. By using preset IP access information, an SI handler unit(240) obtains channel configuration information of the mobile service data from the broadcast signal. The SI handler unit extracts encoding format information of each IP stream component of the corresponding virtual channel service which is packetized to RTP and received from the obtained channel configuration information. According to the extracted encoding format information, a decoding unit(280) decodes the mobile service data of the corresponding IP stream component.
