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

摘要

A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcasting system includes a receiving unit, an SI handler, and a decoding unit. The receiving unit receives broadcast signals including mobile service data and main service data. Herein, the mobile service data may configure a data group, and the data group may include a signaling information region in some of a plurality of data regions. Also, the signaling information region may include TPC signaling data and FIC signaling data. The SI handler acquires channel configuration information of the mobile service data from the broadcast signal using pre-decided IP access information, and extracts encoding format information for each IP stream component within a corresponding virtual channel service RTP-packetized and received from the acquired channel configuration information. The decoding unit decodes the mobile service data of the corresponding IP stream component based upon the extracted encoding format information.

主权项

1. A method of transmitting a broadcast signal in a transmitter, the method comprising:
transmitting a transmission frame including a plurality of slots during which data groups of mobile data are transmitted, the mobile data being encoded through a Reed-Solomon (RS) frame, each data group including a plurality of regions, each region including a plurality of data blocks, each data block including contiguous data segments, wherein first and second regions in each data group include at least three known data sequences which are spaced apart by regular data segments, and the first region further includes signaling information of the mobile data in specified data segments, wherein the signaling information includes first channel information providing binding information between a mobile service identifier and an ensemble being a collection of services of the mobile data, and second channel information describing the transmission frame and the data groups, wherein the ensemble includes a service map table (SMT) providing IP address information for a service, and wherein the service includes a mobile service component and the SMT includes an encoding parameter identifying an encoding format of the mobile service component.
