Abstract

The present technique relates to a receiving device, a receiving method, a transmitting device, and a transmitting method that can satisfactorily operate an application which is executed in conjunction with AV content.

A receiving device is provided which includes: a trigger information acquiring unit that acquires trigger information including at least location information as information for controlling an operation of an application which is executed in conjunction with AV content; a metadata acquiring unit that acquires application control information for controlling the operation of the application; and an application control unit that controls the operation of the application based on the trigger information and the application control information. The present technique can be applied to, for example, a TV receiver.
