Abstract: A method for signaling preamble structure parameters. The method includes generating a bootstrap symbol that signals a single 8-bit preamble structure value. The single 8-bit preamble structure value identifies four different preamble structure parameters of a preamble that follows the bootstrap symbol. The method further includes generating a transmission frame including the bootstrap symbol, the preamble, and a data payload, and outputting the transmission frame for transmission via a terrestrial broadcast. The single 8-bit preamble structure value is limited to signaling a subset of different combinations of the four different preamble structure parameters.

The preamble structure value indicates one of a plurality of different combinations of the preamble structure parameters of a preamble that follows the bootstrap symbol. The preamble includes a first part and a second part. A transmission frame that includes the bootstrap symbol, the preamble, and a data payload is generated. The transmission frame is output for transmission. Further, one of the preamble structure parameters is a forward error correction mode for the first part of the preamble.

Abstract: A data processing apparatus includes a group-wise interleaving unit that performs group-wise interleaving; and a block interleaving unit that performs block interleaving in such a manner that an LDPC code obtained by performing the group-wise interleaving is written in m number of columns as storage regions arranged in the row direction. A type of the block interleaving includes a type A and a type B. A MODCOD which is a combination of the LDPC code and the modulation scheme includes a MODCOD-A which is a MODCOD based on the assumption that the block interleaving of the type A is performed, and a MDOCOD-B which is a MDOCOD based on the assumption that the block interleaving of the type B is performed.

Abstract: A transmission apparatus and transmitting method for signaling parameters of a preamble, and a reception apparatus and receiving method for decoding the preamble. The transmitting method includes generating, using processing circuitry of a transmission apparatus, a bootstrap symbol based on the parameters of the preamble.
