TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
The present technology relates to a transmitting device, a transmitting method, a receiving device and a receiving method which make it possible for an information amount for additional information in a physical layer to be adequately secured. The transmitting device generates and transmits an orthogonal frequency division multiplexing (OFDM) signal in which additional information is allocated to an additional carrier for each group into which additional carriers used for transporting additional information of a physical layer, from among the carriers of the OFDM signal of one frame, are grouped, where the number of groups corresponds to the discrete Fourier transform (DFT) size when an inverse discrete Fourier transform (IDFT) of the OFDM signal is performed. The receiving device receives the OFDM signal and acquires from the OFDM signal the additional information corresponding to the number of groups corresponding to the DFT size. This technology can, for example, be applied when transmitting or receiving an OFDM signal.
The present technique relates to a reception apparatus, a transmission apparatus and a data processing method that allow a digital television broadcast to be more flexibly operated. A reception apparatus receives broadcast signals transmitted by use of a frequency division multiplex scheme (FDM). Then, on the basis of control-information-presence information that is included in first control information obtained from the broadcast signals and serving as control information for a physical layer, and that indicates the presence or absence of second control information serving as control information for layers higher than the physical layer, the reception apparatus processes the second control information transmitted for each hierarchical layer. The present technique can be applied, for example, to a receiver capable of receiving a digital television broadcast.
