The present technology relates to a reception apparatus, a reception method, a transmission apparatus and a transmission method in which NRT service is provided in digital broadcasting using an IP transmission method. There is provided a reception apparatus including: a channel selection control unit that performs a channel selection control of channel-selecting digital broadcasting using the IP transmission method; an acquisition control unit that controls acquisition of an application delivered through broadcasting or communication in the digital broadcasting based on signaling information transmitted at a layer higher than an IP layer in a protocol layer of the IP transmission method; and an application execution unit that executes the application acquired. The present technology is applicable to a television receiver, for example.
