Abstract

This technique relates to a receiving device, a receiving method, a providing device, a providing method, programs, and a broadcasting system that can control operations of external devices connected to the receiving device in synchronization with progress of a show being received.

When the application control type in an application control descriptor is 2, the receiving device receives command information contained in a digital broadcast signal, and acquires and starts a new information service application and the like in accordance with the received command information. 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 acquires and starts the new information service application and the like. This disclosure can be applied not only to controlling the receiving device from the broadcasting side, but also to controlling external devices connected to the receiving device.

Claims

1. A receiving device that receives content broadcast via a broadcasting network, the receiving device comprising:

a receiving unit configured to receive a broadcast signal broadcast via the broadcasting network;

a command information acquiring unit configured to acquire, from the received broadcast signal, command information containing command destination device information designating at least one of a receiving device main unit and an external device that can be connected to the receiving device, and a command related to a predetermined application program executed in synchronization with progress of the content;

a command information analyzing unit configured to perform an operation related to the predetermined application program in accordance with the command information; and

an external device control unit configured to cause the external device to perform an operation related to the predetermined application program in accordance with the command information.
