Patent attributes
The present technology relates to a reception device, a data processing method, and a transmission/reception system capable of shortening time to output a packet. The reception device receives a transmission signal obtained by processing a multiplexed stream including a plurality of packets, analyzes transmission control information for controlling transmission of the transmission signal, decodes the transmission signal on the basis of an analysis result of the transmission control information, analyzes the multiplexed stream obtained by decoding the transmission signal and sets packet division information for dividing the packets from the multiplexed stream, the packet division information according to at least one of the analysis result of the transmission control information or an analysis result of the multiplexed stream, and divides the multiplexed stream into the packets on the basis of the set packet division information. The present technology is applicable to a receiver of digital broadcasting, for example.
