Abstract: The invention relates to a transmitting system, comprising an SNS client that receives SNS messages from at least one SNS server, and a transmitter which transmits a broadcast signal, including the SNS messages and mobile service data, for a mobile broadcast. The transmitter includes: an RS frame encoder, which performs RS encoding and CRC encoding on the mobile service data for the mobile broadcast so as to build RS frames, and divides each RS frame into a plurality of portions; a group-forming unit, which forms data groups that contain each of the plurality of portions, and which adds known data sequences and signaling data to each data group; an inter-leaver for interleaving data of the data groups; and a trellis encoding unit for trellis-encoding the interleaved data.
