A method for transmitting a physical layer data frame of a broadcast system, the method comprising: generating a subframe (207a, 207b) of a payload portion of the physical layer data frame, wherein the subframe comprises one or more physical layer pipes, PLP; generating a preamble of the physical layer data frame, comprising basic signaling and detail signaling, the basic signaling enabling a receiver to begin to receive a remainder of the physical layer data frame and to decode contents of the detail signaling, and the detail signaling enabling the receiver to decode at least a portion of the payload of the physical layer data frame, wherein the detail signaling comprises a first parameter set (1311,1321) associated with the subframe (207a, 207b) followed by one or more second parameter sets (1312, 1313, 1314, 1315, 1322, 1323, 1324, 1325) each associated with a corresponding one of the one or more PLPs, and wherein each second parameter (1312, 1313, 1314, 1315, 1322, 1323, 1324, 1325) set associated with the one or more PLPs comprises a type of forward error correction, FEC, of the PLP and a time interleaving mode of the PLP, and wirelessly broadcasting the physical layer data frame comprising the preamble and the subframe (207a, 207b), characterised in that the first parameter set (1311,1321) associated with the subframe (207a, 207b) begins with a first parameter indicating a total of number of bits in the first and the one or more second parameter sets, and the one or more second parameter sets follow the first parameter set in an order from legacy version signaling to later version signaling or each second parameter set associated with the one or more PLPs comprises a second parameter indicating a total number of bits in the respective second parameter set. generating a subframe (207a, 207b) of a payload portion of the physical layer data frame, wherein the subframe comprises one or more physical layer pipes, PLP; generating a preamble of the physical layer data frame, comprising basic signaling and detail signaling, the basic signaling enabling a receiver to begin to receive a remainder of the physical layer data frame and to decode contents of the detail signaling, and the detail signaling enabling the receiver to decode at least a portion of the payload of the physical layer data frame, wherein the detail signaling comprises a first parameter set (1311,1321) associated with the subframe (207a, 207b) followed by one or more second parameter sets (1312, 1313, 1314, 1315, 1322, 1323, 1324, 1325) each associated with a corresponding one of the one or more PLPs, and wherein each second parameter (1312, 1313, 1314, 1315, 1322, 1323, 1324, 1325) set associated with the one or more PLPs comprises a type of forward error correction, FEC, of the PLP and a time interleaving mode of the PLP, and wirelessly broadcasting the physical layer data frame comprising the preamble and the subframe (207a, 207b), characterised in that the first parameter set (1311,1321) associated with the subframe (207a, 207b) begins with a first parameter indicating a total of number of bits in the first and the one or more second parameter sets, and the one or more second parameter sets follow the first parameter set in an order from legacy version signaling to later version signaling or each second parameter set associated with the one or more PLPs comprises a second parameter indicating a total number of bits in the respective second parameter set.
