However, digital broadcast reception is not substantially performed when the digital broadcast media application is not driven.

Therefore, in the state where the information terminal 10 and the digital broadcast receiver 11 are physically connected, the user can normally watch the digital broadcast only by driving the digital broadcast media application through a user interface (UI) or a command mode. have.

As described above, the current digital broadcasting media application (DVB-H / DMB application) has a plug & auto driving function (Plug & Auto) to automatically play digital broadcasting contents received from the digital broadcasting receiver 11 connected to the USB port. There is a problem that does not support Auto Launch.

Therefore, even if a digital broadcast media application is installed in the information terminal 10 and a digital broadcast receiver 11 such as a DVB-H / DMB dongle is connected through a USB port, the user may not be able to view the digital broadcast. There is an inconvenience in that the digital broadcasting media application must be driven every time.

The present invention proposes a method for automatically turning on / off a digital broadcasting media application according to a state in which a digital broadcasting receiver is connected to an information terminal.

The present invention provides a digital broadcast receiver for receiving a digital broadcast signal, a communication interface for receiving the digital broadcast signal, a digital broadcast signal received from the digital broadcast receiver, and providing functions related to a digital broadcast service. A digital broadcast media application that generates command data corresponding to the selection of functions related to the digital broadcast service from a user; and a digital broadcast that automatically drives the digital broadcast media application when the digital broadcast receiver is connected to the communication interface. It includes a control unit for performing a service control.

The information terminal may further include an input unit for selecting a function desired by a user or receiving information, a display unit for displaying the received video signal, and a voice processor for outputting a voice signal under the control of the controller.

The communication interface may be a USB port, and the controller may include an application plug and auto driving component.

2 is a block diagram illustrating an internal configuration of an information terminal according to an exemplary embodiment of the present invention.

The display unit 21 serves to display an image signal under the control of the controller 20. In an embodiment of the present invention, an LCD (Liquid Crystal Display) may be used for the display unit 21.

The input unit 22 is used to select a function desired by a user or input information. For example, a keypad, a touch pad, or the like may be used.

The voice processor 23 converts the digital voice signal into an analog voice signal under the control of the controller 20 and outputs the analog voice signal through the speaker.

The communication interface 24 is connected to a digital broadcast receiver 11 (eg, DVB-H dongle, DMB dongle) for receiving a broadcast signal and used to receive a broadcast signal from the digital broadcast receiver 24. In an embodiment of the present invention, the communication interface 24 may use a USB interface for USB communication.

The digital broadcasting media application 25 is installed in the information terminal and includes an audio / video decoder and a player component for playing digital broadcasting contents. The digital broadcasting media application 25 is inputted from the digital broadcasting receiver 24. The digital broadcast signal is reproduced so that the user can watch it. To this end, when the user selects functions related to a digital broadcasting service (eg, a DMB service), the digital broadcasting media application 25 generates command data corresponding thereto. The digital broadcast media application 25 receives a command related to a digital broadcast service (for example, DMB playback and DMB interruption) from a user, generates command data corresponding thereto, and provides the same to the controller 20. That is, the digital broadcast media application 25 transmits command data corresponding to the request to the control unit 20 when the user selects a function for the request for the digital broadcast service or the request for terminating the digital broadcast service.

Meanwhile, the digital broadcast media application 25 performs operations such as digital broadcast reproduction (DMB playback), digital broadcast interruption (DMB interruption), etc. at the request of the user as described above. The media application must be running on the information terminal. That is, the digital broadcasting media application is normally driven and displayed on the information terminal, and then receives a command related to various DMB services from the user.

Conventionally, even when the digital broadcast receiver 11 is connected to an information terminal through a communication interface 24 such as a USB port, the digital broadcast media application 25 is not automatically driven, and the user manually enters the digital broadcast media application ( The operation of driving 25 had to be performed manually.
