Claim:
1. A method of transmitting broadcast signals, the method comprising: forward error correction (FEC) encoding broadcast data to add first parity data to the broadcast data; permuting the FEC-encoded broadcast data; block interleaving the permuted broadcast data; convolutional interleaving the block-interleaved broadcast data; first encoding signaling information for signaling the broadcast data to add second parity data to the signaling information; second encoding the first-encoded signaling information at a code rate; mapping the convolutional interleaved broadcast data and the second-encoded signaling information into a frame that includes a first region and a second region, wherein the first region includes the signaling information and first known data, and the second region includes the broadcast data and second known data, the second known data being different from the first known data; and transmitting the broadcast signals including the frame, wherein the signaling information includes information for identifying a number of the first parity data.
