Claim:
1. A method for transmitting broadcast signals, the method comprising: generating an FEC (Forward Error Correction) frame by encoding at least broadcast data or signaling information with an FEC code, wherein the broadcast data include at least video data or audio data and wherein the signaling information includes at least video codec information for the video data or audio codec information for the audio data; dividing the FEC frame into a plurality of portions, wherein the plurality of portions have a same size; interleaving data of the plurality of portions; first encoding transmission parameters to add parity data; second encoding the first-encoded transmission parameters at a code rate; and transmitting the broadcast signals including a transmission frame that contains the interleaved data and the second-encoded transmission parameters, wherein the transmission frame comprises multiple sub-frames that are concatenated in time, and wherein the transmission parameters include FEC code information and information related to at least one sub-frame of the multiple sub-frames.
