1. A method for transmitting broadcast signals, the method comprising:
LDPC (Low Density Parity Check) encoding broadcast data that is carried by a physical path; LDPC encoding signaling data, the LDPC encoded signaling data including a group identifier field for identifying a group to which a current physical path belongs; time interleaving the LDPC encoded broadcast data by a twisted fashion; building at least one signal frame by assembling the time interleaved broadcast data and the LDPC encoded signaling datas; and transmitting the broadcast signals including the built at least one signal frame. |
