The present technology relates to a reception device, a transmission device, and a data processing method that enable a flexible operation of a service using an application that accompanies content.

A reception device includes: a reception unit that receives content; an acquisition unit that acquires an application in accordance with acquisition source information indicating an acquisition source of the application accompanying the content, the acquisition source information being included in control information transmitted together with the content; and a control unit that instantly starts the acquired application. The present technology can be applied to a television set capable of receiving digital broadcasts, for example.

An association with a system timing at the time of transmission is secured without changing a display timing in text information of a subtitle, and a reception side displays the subtitle at an appropriate timing. A packet in which a document of the text information of the subtitle having display timing information is included in a payload is generated and transmitted in synchronization with a sample period. A header of the packet includes a time stamp on a first time axis indicating a start time of the corresponding sample period. The payload of the packet further includes reference time information of a second time axis regarding the display timing associated with the start time of the corresponding sample period.
