Abstract: A device and method for executing an application related to Audio/Video (A/V) content are provided. The device includes a controller for obtaining an identifier of the application, for sending a query message including the identifier and platform information of the device to a download server having a predefined address, for receiving a response message to the query message, and for executing the application based on the response message, and a transceiver for performing an operation of sending and receiving the query message and the response message, thereby making it possible to provide applications related to A/V content to all types of application execution devices regardless of the types of platforms of the devices. Thus, A/V content providers may provide applications to A/V content consumers without the limitations on the data broadcasting networks and the recording capacity of the media.
