This technique relates to a receiving device, a receiving method, a providing device, a providing method, a program and a broadcasting system that can notify the receiving side of control information such as the timing to synchronize an application program with progress of a show without using a television broadcast signal.When the application control type written in the application control descriptor is 3, the receiving device acquires application control data from a server, and, for example, acquires and starts a new information service application in accordance with the segment data forming the application control data. When an external device is designated as the command destination device, the receiving device generates a command for the external device, and outputs the command to the external device. In accordance with the command from the receiving device, the external device, for example, acquires and starts the new information service application. This disclosure can be applied in a case where the receiving device is controlled from the broadcasting side.
