摘要: Processing and transmitting transmission frames. A method for processing a transmission frame, includes receiving a transmission frame including a bootstrap portion, a preamble portion, and a payload portion. The boot strap portion of the received transmission frame is processed, by processing circuitry of a reception apparatus, to extract preamble structure information from one of four bootstrap symbols included in the bootstrap portion. The preamble portion of the transmission frame is decoded, by the processing circuitry, based on the extracted preamble structure information. A first one of the four bootstrap symbols is used for synchronization and a last one of the four bootstrap symbols in the bootstrap portion includes the preamble structure information. Further, the preamble structure information indicates a structure of one or more preamble symbols in the preamble portion that follows the last symbol.

摘要: 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.

摘要: The present technology relates to a data processing apparatus and a data processing method that are able to secure good communication quality in data transmission using an LDPC code. One symbol is mapped to one of 16 signal points prescribed in 16APSK, with code bits of four bits of an LDPC code having a code length of 16200 bits and a code rate of 7/15 as one symbol. 16 signal points prescribed in 16APSK are four signal points on an inner circle and 12 signal points on an outer circle, and a radius ratio of the inner circle and the outer circle is 5.25. The present technology may be applied to, for example, a case of performing data transmission using an LDPC code.

摘要: A code bit of an LDPC code in which a code length is 16200 bits and an encoding rate is 7/15 is interchanged with a symbol bit of a symbol corresponding to any of 8 signal points defined by 8PSK. In the interchanging, when 3 bits of code bits stored in three units of storages having a storage capacity of 16200/3 bits and read bit by bit from the units of storages are allocated to one symbol, a (#i +1)-th bit from a most significant bit of the 3 bits of code bits is set to a bit b#i, a (#i +1)-th bit from a most significant bit of 3 bits of symbol bits of the one symbol is set to a bit y#i, and a bit b0, a bit b1, and a bit b2 are interchanged with a bit y1, a bit y0, and a bit y2.

摘要: 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. The bootstrap symbol is prefixed to a frame that includes the preamble using the circuitry. The bootstrap symbol is selected from a plurality of patterns. Further, the plurality of patterns represent at least a subset of predetermined combinations of the parameters of the preamble including an FFT (Fast Fourier Transform) size, a guard interval, a frequency domain displacement component of a SPP (Scattered Pilot Pattern) and a L1 mode.
