This technology pertains to a reception device, a reception method, a transmission device, and a transmission method that make it possible to acquire channel-selection information more efficiently. This invention provides a reception device that has the following: a reception unit that receives digital broadcast waves using IP transport; a communication unit that communicates with a server via a network and receives first signaling information for acquiring broadcast content transported via the aforementioned broadcast waves; an acquisition unit that, on the basis of said first signaling information, acquires a physical parameter used in the physical layer of the IP-transport protocol stack; and a control unit that, on the basis of said physical parameter, controls the behavior of units that perform channel-selection processing. This technology can be applied, for example, to a mobile handheld receiver. |
