Abstract

An apparatus for transmitting a broadcast signal includes an encoder encoding mobile data for FEC (Forward Error Correction) to build RS (Reed Solomon) frames, wherein each row of a payload of each of the RS frame includes transport packets of the mobile data including IP datagrams; a signaling encoder encoding signaling data, wherein the signaling data includes TPC (transmission parameter channel) data and FIC (fast information channel) data, wherein the TPC data includes transmission parameters and the FIC data includes channel binding information between services and ensembles; a group formatter forming data groups including the encoded mobile data and encoded signaling data; a packet formatter formatting data packets including data in the data groups; a multiplexer multiplexing the mobile data in the data packets and main data in main data packets; and a transmission unit transmitting a transmission frame including the multiplexed data.

Claims
