Abstract

The present technique relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method capable of supporting various service modes. The reception apparatus obtains first meta data including class information for providing, in multiple modes, a service identified by an IP address and transmitted by a broadcast wave of digital broadcast using an IP transmission method, and controls reproduction of a component by connecting to a stream of the component constituting the service for each of the multiple modes on the basis of the class information included in the first meta data. The present technique can be applied to, for example, a fixed receiver such as a television receiver, a mobile receiver such as a smartphone, and the like .
