Abstract: A code bit of an LDPC code in which a code length is 16200 bits and an encoding rate is 8/15 is interchanged with a symbol bit of a symbol corresponding to any of 8 signal points defined by 8PSK. 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 is interchanged with a bit y1, a bit b1 is interchanged with a bit y0, and a bit b2 is interchanged with a bit y2.

Abstract: The present technology relates to a reception apparatus and a data processing method that enable clock synchronization in a more suitable manner. The reception apparatus receives a digital broadcast signal of an IP transmission method that includes time information and a stream of content. The time information includes a seconds field and a nanoseconds field. The reception apparatus then generates a processing clock synchronized with the time information on the basis of the time information included in the digital broadcast signal, and processes the stream included in the digital broadcast signal on the basis of the processing clock. The present technology can be applied to, for example, television receivers conforming to the IP transmission method.

Abstract: 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.

Abstract: The present technology relates to a reception apparatus and a data processing method that permit efficient processing of time information.The reception apparatus receives a digital broadcasting signal based on an IP transport scheme, acquires time information from a physical layer frame transported in a physical layer of a protocol stack for the IP transport scheme, converts the acquired time information into the same data format as data provided in a payload of the physical layer frame, and outputs the converted time information to a processing section that performs a given process relating to an upper layer that is a layer higher than the physical layer. The present technology is applicable, for example, to a television receiver that supports an IP transport scheme.
