Abstract
The present technique relates to a data processing apparatus and a data processing method each of which enables a burden imposed on processing on a reception side to be reduced. A data processing apparatus produces signaling containing a Null cell number exhibiting the number of Null cells of cells of a sub-frame included in a physical layer frame, and processes the signaling so as for the signaling to be contained in a preamble of the physical layer frame, thereby enabling a burden imposed on processing on a reception side to be reduced. The present technique, for example, can be applied to data transmission complying with the broadcasting standards such as ATSC3.0.
Claims17
A reception apparatus, comprising:
- receive circuitry configured to receive a signal via broadcast, the signal conveying at least one physical layer frame including signaling and at least one subframe, the at least one subframe having as many as two subframe boundary symbols;
- and
- processing circuitry configured to process the received signal,
- wherein if at least one subframe boundary symbol of the as many as two subframe boundary symbols is present in the at least one subframe:
- the at least one subframe boundary symbol includes a number of null cells and a number of active data cells arranged at frequencies between frequencies of the null cells, with at most half of the null cells being disposed at frequencies lower than those of the active data cells and a remainder of the null cells being disposed at frequencies higher than those of the active data cells, and
- the signaling includes a null cell number indicative of the number of null cells in the at least one subframe boundary symbol.
A method for a reception apparatus, comprising:
- receiving a signal via broadcast, the signal conveying at least one physical layer frame including signaling and at least one subframe, the at least one subframe having as many as two subframe boundary symbols;
- and
- processing the received signal,
- wherein if at least one subframe boundary symbol of the as many as two subframe boundary symbols is present in the at least one subframe:
- the at least one subframe boundary symbol includes a number of null cells and a number of active data cells arranged at frequencies between frequencies of the null cells, with at most half of the null cells being disposed at frequencies lower than those of the active data cells and a remainder of the null cells being disposed at frequencies higher than those of the active data cells, and
- the signaling includes a null cell number indicative of the number of null cells in the at least one subframe boundary symbol.
A non-transitory computer readable medium including computer executable instructions which, when executed by a processor of a reception apparatus, cause the reception apparatus to perform a method comprising:
- receiving a signal via broadcast, the signal conveying at least one physical layer frame including signaling and at least one subframe, the at least one subframe having as many as two subframe boundary symbols;
- and
- processing the received signal,
- wherein if at least one subframe boundary symbol of the as many as two subframe boundary symbols is present in the at least one subframe:
- the at least one subframe boundary symbol includes a number of null cells and a number of active data cells arranged at frequencies between frequencies of the null cells, with at most half of the null cells being disposed at frequencies lower than those of the active data cells and a remainder of the null cells being disposed at frequencies higher than those of the active data cells, and
- the signaling includes a null cell number indicative of the number of null cells in the at least one subframe boundary symbol.
