The present invention relates to a set-top box and a control method thereof, and more particularly, to a set-top box and its control method capable of efficiently switching to the initial state based on the WINCE.

In general, a TV (Television) portal service provides a home network service that provides a convenient and comfortable life enjoyment to users, and refers to a service that can use desired media content on a TV.

Such a TV portal service is provided to a TV through a set top box, and the set top box executes each independent application program such as an individual service such as a movie, music, and broadcast on a platform system.

In this case, application program management is managed by an operating system (OS) of the set-top box. Here, the operating system of the set-top box may be divided into XP-based and WINCE-based.

In this case, if the applications do not terminate normally due to page faults, system interrupts, deadlocks, overflows, etc. while the system is in use, the applications remain in memory. Problems such as adversely affecting the performance of the system or system down may occur.

At this time, when the operating system of the set-top box is XP-based, if the system down phenomenon occurs, it can be returned to the initial state by using the hooking function. Here, the hooking function means a function of intercepting an input signal and performing a necessary operation before the command signal is transmitted to the uppermost window.

However, if the operating system of the set-top box is based on WINCE (Window CE), there is a problem that it is difficult to solve even if a system down phenomenon occurs because the hooking function is not supported.

Therefore, there is a need for a treatment method for a system down phenomenon or a transition to an initial state in a WINCE-based set-top box.

The present invention is to meet the above-described needs, an object of the present invention to provide a set-top box capable of efficiently switching to the initial state based on the WINCE and a control method thereof.

The WINCE-based set-top box according to an embodiment of the present invention for achieving the above object is a receiving unit for receiving an initialization signal, and to switch the operating state of the set-top box to the initial state according to the received initialization signal It includes a state management unit.

Preferably, the state manager may forcibly terminate the application program and switch to the initial state when the initialization signal is received while the application program running on the set-top box is stopped.

More preferably, the storage unit may further include a storage unit for storing a system message corresponding to the initialization signal.

On the other hand, the control method of the WINCE-based set-top box according to an embodiment of the present invention, the step of receiving an initialization signal, and switching the operation state of the set-top box to the initial state according to the received initialization signal It may include.

Preferably, when the initializing signal is received while the application program running on the set-top box is stopped, the switching may be forcibly terminated and switched to the initial state.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a set-top box according to an embodiment of the present invention.

Referring to FIG. 1, the set top box 200 includes a receiver 210, a storage 220, a state manager 230, and a controller 240.

The remote controller 100 is an input device for generating an initialization signal that can be switched to the initial state while using the TV portal service.

The remote controller 100 controls the set top box and the TV screen and inputs a user command. That is, various signals may be input through a remote controller button (for example, TV channel up / down, volume up / down, direction keys, hot keys, letters / numbers, color keys, etc.).

The receiver 210 receives an input signal generated from the remote controller 100.

Specifically, the receiver 210 may receive an initialization signal from the remote controller 100. That is, the receiver 210 generates a system message corresponding to the initialization signal received from the remote controller 100 based on the remote controller key mapping table stored in the storage 220 and outputs it to the state manager 230 and the controller 240. do.

The storage unit 220 stores the application program of the entire set-top box. In addition, the storage unit 220 may store the class identification number of the state management unit 230 in the registry. This can be set and stored from the designer.

In addition, the storage unit 220 may store a remote controller key mapping table. The remote controller key mapping table refers to a table in which system messages corresponding to input signals generated from the remote controller 100 are recorded.

At this time, the receiver 210 outputs a system message to the state manager 230 based on the class ID of the state manager 230.

The method of outputting the system message to the state manager 230 by the receiver 210 may be implemented through the following algorithm.

HWND RegGetHomeWindowClass (void) // returns the window handle of the state manager

static VOID KeybdEvent (DWORD dwVk, DWORD dwSc, KEY_STATE_FLAGS flags)

{

hWnd = RegGetHomeWindowClass (); // Get Window Handle of State Manager

    {

keybd_event ((BYTE) dwVk, (BYTE) dwFlags, dwFlags, 0); // keyboard event

PostKeybdMessage (hWnd, uCharacter, nShiftState, 1, & nShiftState, &uCharacter); // deliver relevant system message to status management

}

}

According to the above algorithm, the reception unit 210 obtains the window handle (for example, class identification number) of the state management unit and outputs a corresponding system message to the state management unit 230 when a keyboard event occurs.

The state manager 230 may switch the operation state of the set-top box 200 to an initial state according to the system message output from the receiver 210.

In addition, even when a system down phenomenon occurs, the state manager 230 may escape the system down phenomenon by processing an input signal output from the receiver 210.

In addition, when the plurality of applications are running in the process of switching the operation state of the set-top box 200 to the initial state, the state manager 230 may terminate the plurality of applications by referring to the registry of the storage unit 220. Can be. That is, the state management unit 230 may safely terminate the corresponding application when an application such as karaoke or a game is running.

Alternatively, the state manager 230 may hide a plurality of application programs and switch to an initial state according to the received initialization signal.

The controller 240 may control the overall operation of the set top box 200. In addition, the controller 240 may perform an operation according to an input signal output from the receiver 210.

For example, when a music program execution input signal is received, the controller 240 may execute a music program and provide the same to a TV (not shown).

That is, the controller 240 may execute the application program set in the configuration file and execute the application program selected by the user.

2 is a flowchart illustrating a control method of a set-top box according to an embodiment of the present invention.

Referring to FIG. 2, when an initialization signal is received from the remote controller (S310), the set-top box switches the operation state of the set-top box to an initial state according to the received initialization signal (S320). Here, the initialization signal is generally a signal generated when the 'home key' is input, and refers to a signal that can be switched to the initial state while using the TV portal service.

This is because the set-top box is provided with a state management unit so that the received input signal can be processed immediately, so that even if a system down phenomenon occurs, this phenomenon can be immediately escaped.

In addition, when a plurality of applications are being executed by this, it is possible to switch to the initial state at a time without terminating the plurality of applications executed by the user.

3 is a flowchart illustrating a control method of a set-top box according to another embodiment of the present invention.

Referring to FIG. 3, the set top box receives an input signal from a remote controller (S410). At this time, the state management unit of the set-top box when the received input signal is the initialization signal (S420: Y), if the application running on the set-top box is stopped, that is, if a system down phenomenon occurs, forcibly terminate the running application program, The operation state of the set-top box is switched to the initial state (S430).

As a result, it is possible to efficiently escape from the system down phenomenon of the set-top box.

As described above, according to the present invention, the set-top box can be efficiently switched to the initial state on the basis of WINCE, so that the user's convenience can be achieved.

In addition, even if a system down phenomenon of the set-top box provides a way to easily escape using the remote control.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
