Abstract: The present technology relates to a reception device, reception method, and program that can prevent erroneous detection of a predetermined signal, such as a P1 signal, included in, for example, a received signal such as DVB-T2.A correlation calculation unit obtains a correlation value between received signals including a predetermined signal in which an original signal and a duplicate signal obtained from a copy of at least a part of the original signal are disposed. An average power calculation unit obtains average power of the received signals. A normalization unit obtains a normalized correlation value obtained by normalizing the correlation value by the average power. The present technology can be applied to a case where a P1 signal being a preamble signal is detected from a received signal such as DVB-T2, for example.

Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that realize a process related to emergency warning information in DVB-T2 standard more promptly at a low power consumption. There is provided a transmission device including an emergency warning information acquisition unit configured to acquire emergency warning information, a content acquisition unit configured to acquire content, a transmission frame generation unit configured to generate a T2 frame including emergency warning notification information indicating that emergency warning information is being transmitted in P1 signaling or L1-pre signaling as a T2 frame, according to DVB-T2 standard, composed of a P1 symbol including P1 signaling, a P2 symbol including L1-pre signaling, and a symbol of data, and a transmission unit configured to transmit the T2 frame as a digital broadcast signal. The present technology can be applied to a transmitter that is capable of transmitting the digital broadcast signal according to the DVB-T2 standard for example.
