Abstract

The present technique relates to a reception apparatus, a reception method, a program, and a reception system capable of starting decoding of data in a short time. A reception apparatus according to an aspect of the present technique includes a demodulation unit configured to demodulate a modulated signal used to transmit transmission control information about data and the data to be transmitted, a first decoding unit configured to decode the transmission control information obtained by demodulation performed with the demodulation unit, a storage unit configured to store the data obtained by demodulation performed with the demodulation unit, and a second decoding unit configured to decode the data stored in the storage unit on the basis of the transmission control information decoded by the first decoding unit. The present technique can be applied to a receiver receiving an OFDM signal of DVB-C2.

Claims

1. A reception apparatus comprising:

a demodulation unit configured to demodulate a modulated signal used to transmit transmission control information about data and the data to be transmitted;

a first decoding unit configured to decode the transmission control information obtained by demodulation performed with the demodulation unit;

a storage unit configured to store the data obtained by demodulation performed with the demodulation unit; and

a second decoding unit configured to decode the data stored in the storage unit on the basis of the transmission control information decoded by the first decoding unit.

2. The reception apparatus according to claim 1,

wherein the modulated signal includes a signal used for transmitting the transmission control information and a signal used for transmitting the data, which are arranged in an order of transmission, and

the storage unit stores the data obtained while the transmission control information is being decoded.

3. The reception apparatus according to claim 1,

wherein when the first decoding unit finishes decoding of the transmission control information, the second decoding unit starts decoding the data.

4. The reception apparatus according to claim 1,

wherein the modulated signal is an OFDM signal of DVB-C2,

the transmission control information is L1 information transmitted with a Preamble Symbol, and
