1. An apparatus for receiving a broadcast signal, the apparatus comprising:
- a tuner to receive the broadcast signal, wherein the broadcast signal includes a first region and a second region, wherein the first region is concatenated with the second region, wherein the broadcast signal includes known data, signaling information, and service data;
a signaling decoder to decode the signaling information for signaling the service data, wherein the signaling information includes a first field indicating a number of subframes in a frame;
a deinterleaver to deinterleave the service data; and
a decoder to decode the deinterleaved service data,wherein the broadcast signal further includes fast service acquisition information between a physical layer and an upper layer,wherein the signaling information further includes a second field for the fast service acquisition information,wherein the service data includes a data packet which includes a header and a payload,wherein the header of the data packet includes a pointer field which represents start position information of the payload, andwherein the header of the data packet further includes a field which is related with stuffing bytes which fills a portion in front of the payload in the data packet.

Abstract
A method of transmitting a broadcast signal includes encoding mobile data for FEC (Forward Error Correction); encoding signaling information for signaling the mobile data; allocating the encoded mobile data and signaling data into a transmission frame; and transmitting the broadcast signal including the transmission frame, wherein the transmission frame includes a service signaling table having service_type information identifying a type of a service of the mobile data and hidden information indicating whether the service of the mobile data is hidden or not.
