Description

[0001] The present invention relates to an image display apparatus having a malfunction prevention function and a control method thereof,

The present invention relates to an image display device, and more particularly, to an image display device and a control method thereof that can prevent a malfunction that may be caused when a failure occurs in a remote controller or a local key button.

2. Description of the Related Art In general, a remote controller or a local key capable of selecting a specific function and inputting a user-requested command is applied to various electronic products such as a television, a set-top box, a DVD player,

In particular, when a user continuously presses a key for changing a voice or a channel like a TV, the key input is continuously recognized and processed.

In addition, keys such as power on / off are typically configured to recognize and process input values that are pressed once rather than sequentially.

Here, since the key for changing the voice or the channel has a wide variable range, it is inconvenient to input the key once, and when a key for power on / off is input continuously, Since the set is frequently turned on / off by one input, when the key is continuously input, the input is recognized as one input and processed so that it can be operated.

That is, the structure of the conventional local key is configured as a switch as shown in FIG. 1, and the control unit 10 can check the input state of the specific key by measuring the voltage according to the input state.

In other words, the controller 10 recognizes the high state before the specific key is input, and recognizes the low state when the specific key is input.

 At this time, in the case of the key processed by the continuous key input such as the voice or the channel change, the set does not continue according to the intention of the user, but the set can not perform a normal operation in a situation where the input continues.

That is, as described above, the power on / off key recognizes and processes the input as a single input when the user continuously inputs the key continuously, and the key such as the voice or the channel change allows the user to continuously , It is processed by continuous key input and the corresponding operation is continuously performed.

Accordingly, in the case of the power on / off key, the above problem does not occur when the corresponding key is continuously input due to a failure. However, the key such as the voice or the channel change is continuously There is a problem that the user can not qualitatively watch a specific broadcast program, such as when the volume value is continuously changed or the channel number is changed.

In the embodiment of the present invention, a limit range or a preferred range for successive key input is set so that the processing of a key continuously input due to a key failure can be blocked.

Further, in the embodiment of the present invention, the key information of the problem continuously input due to the key failure is provided, so that the user can quickly cope with the problem.

An image display device having a malfunction prevention function according to an embodiment of the present invention includes a key input unit for receiving key data according to a request command input from a user; A memory for storing a limit range value according to input of successive specific key data; And a controller for determining whether to reflect specific key data continuously inputted through the key input unit based on a limit range value stored in the memory.

According to another aspect of the present invention, there is provided a method of controlling an image display apparatus having a key input unit for receiving key data, the method comprising: ; Counting the number of times the first key data is input when the first key data is continuously input; Comparing the number of times the counted first key data is input with a preset limit range; And determining whether to reflect the input first key data according to the comparison result.

According to another aspect of the present invention, there is provided a method of controlling an image display apparatus having a key input unit for receiving key data, the method comprising the steps of: ; Extracting a preference range of the input specific key data when the key data is continuously input; Comparing the set value of the corresponding menu item changed according to the input of the specific key data and the preference range; And determining whether to reflect the input key data according to the comparison result.

The video display device and the control method thereof having the malfunction prevention function according to the embodiment of the present invention can prevent the continuous processing of the key input due to the key failure by setting the limit range for the continuous key input, It is possible to prevent a malfunction that may be caused due to a key failure within a range that does not disturb the user. Also, by providing the user with the key information of the problem, the user can quickly cope with the problem.

FIG. 2 is a block diagram of a video display device having a malfunction prevention function according to an embodiment of the present invention. FIG. 3 is a view showing a key data range setting screen according to an embodiment of the present invention. FIG. 5 is a flowchart for explaining a step-by-step control method of a video display device having a malfunction prevention function according to the first embodiment of the present invention. FIG. FIG. 6 is a flowchart for explaining a step-by-step control method of a video display device having a malfunction prevention function according to a second embodiment of the present invention.

As shown in FIG. 1, an image display apparatus having a malfunction prevention function according to an embodiment of the present invention includes a key input unit 100 for receiving key data according to a request command input from a user, A control unit 120 for determining whether to reflect specific key data continuously inputted through the key input unit based on a limit range value stored in the memory 110, A video signal processor 130 for processing information of specific key data whose reflection is stopped according to a control signal of the controller 120 so that the information can be displayed; And a display unit 140 for displaying an image.

The operation of the image display device having the malfunction prevention function according to the embodiment of the present invention will now be described.

The key input unit 100 receives key data corresponding to a request command input from a user.

That is, the key input unit 100 may be an infrared receiver (not shown) for receiving an infrared signal inputted through a remote controller, or may be a local key input unit (not shown) provided at one side of the image display apparatus have.

When the signal corresponding to the user request command is received through the key input unit 100, the control unit 120 restores the received key data and controls the specific operation according to the restored key data.

At this time, when the user continuously inputs specific key data, the controller 120 reflects the continuously inputted specific key data to perform the corresponding operation, or stops reflecting the continuously inputted specific key data Thereby blocking the execution of the corresponding operation.

That is, the memory 110 stores a limit range value for determining whether key data continuously input is reflected or not.

At this time, the limit range value stores a plurality of different values according to the variable range of the menu item.

In other words, generally, the volume level has a wide variable range from 0 to 100 levels, and the channel switching has a variable range that is smaller than the volume level since it is variable only within a channel range set by the user.

Accordingly, the user can select a menu item, such as a limit range of the menu item according to the volume level increase, a limit range of the menu item according to the volume level decrease, a limit range of the menu item according to the channel up, You can set the limit range.

In addition, as a default, a limit range for each menu item is set at the time of shipment, so that for a menu item for which the user has not set a limit range, the set default value is applied and whether the key data according to the menu item is reflected .

In addition, the memory 110 stores a preference range value of each menu item in addition to the limit range value.

That is, as shown in FIG. 3, there are a limit range 210 and a preference range 220 in a range for determining whether to continuously reflect key data inputted.

In addition, the limit range 210 and the preference range 220 exist for each menu item 200.

The limit range 210 is a range for determining whether to reflect the key data according to the number of consecutively input specific key data, and the preference range 220 is changed according to the specific key data continuously input And determines whether to reflect the key data based on the set value of the menu item.

The operation of determining whether to reflect the input key data based on the limit range 210 and the preference range 220 will be described in more detail in the operation of the control unit 120 to be described later.

The control unit 120 determines whether or not the key data input from the key input unit 100 is a continuous input. If the key data is input continuously, the control unit 120 sets the limit range and the preference range stored in the memory 110 as a reference Whether or not the input key data is reflected.

First, an operation of determining whether or not to continuously reflect key data to be continuously input based on the set threshold value range will be described.

That is, when the specific key data is continuously input, the control unit 120 controls whether to perform the operation according to the specific key data based on the limit range according to the input key data.

In other words, the control unit 120 confirms the number of input of the continuously input key data, and reflects the inputted key data only by the limit range.

That is, when the input key data is key data for volume adjustment, the variable range for adjusting the volume is 0 to 100, and the limit range for the volume item is set to 20, the controller 120 Continuously increases / decreases the corresponding volume from the current set level to the 20th level according to the continuously input key data.

When the corresponding key data is continuously inputted after performing the corresponding operation by reflecting the corresponding input key data by the set limit range, the controller 120 stops reflecting the input key data and is inputted for a predetermined time The key data is checked.

More specifically, the control unit 120 includes a count unit 122 for counting the number of times of input of specific key data continuously input through the key input unit 100, A comparator 124 for comparing the number of times of input of the counted specific key data with the limit range set value stored in the memory 110, And an operation control unit 126 for determining whether to reflect or not.

The counting unit 122 determines whether specific key data is continuously inputted through the key input unit 100. When the key data is continuously input, the counting unit 122 counts the number of key data input.

The comparison unit 124 extracts a limit range value according to the input key data from the memory 110, and compares the extracted limit range value with the counted input number.

If the input number of the key data does not reach the limit value in accordance with the comparison result, the operation control unit 126 reflects the inputted key data to perform the corresponding operation, and if the input number of the key data is And stops reflecting the input key data when the limit range value is reached.

That is, for example, if the currently inputted key data is key data for volume increase, the currently set volume level is 20 level, and the limit range of the key data according to the volume increase is 20, Continuously increases the volume by reflecting the key data according to the continuously input volume increase.

If the number of times of reflection of the key data due to the volume increase exceeds 20, which is the set limit value, that is, the operation control unit 126 increases the volume level to 40 according to the volume increase key data continuously inputted , It is checked whether the corresponding volume level key data is continuously input.

When the key data for increasing the volume level is continuously input even when the volume level is increased to 40 levels, the operation control unit 126 stops reflecting the input key data, Do not.

Then, the operation control unit 126 checks the key data input after the reflection of the key data is stopped, and controls the next operation according to the type of the key data inputted after the reflection of the key data is stopped .

That is, when the reflected key data is continuously inputted even after the reflection of the specific key data is stopped, the operation control unit 126 determines that the input of the key data is an error, To be displayed.

In addition, when the reflection of the specific key data is stopped, the operation control unit 126 reflects the corresponding key data to be input, .

In other words, the operation control unit 126 reflects the key data continuously inputted only within the set limit range, so that the corresponding operation is performed.

When the number of times of inputting the key data reaches the limit range, new key data is input at least once, or only when the input of the stopped key data is stopped and then re-input, So that the operation is performed.

That is, when the user continuously inputs specific key data, the user can continuously input corresponding key data only a number of times corresponding to the limit range corresponding to the corresponding key data. If the user continuously inputs the corresponding key data It is necessary to re-input the key data after inputting the new key data or re-input after stopping the input of the key data.

The image signal processing unit 130 generates a warning check screen including the information of the key data whose reflection is stopped according to the control signal of the controller 120, and performs signal processing to display the alert check screen.

As shown in FIG. 4, the display unit 140 displays the signal-processed warning confirmation screen to allow the user to quickly identify a particular key that is currently abnormally input and to promptly respond to the specific key.

In addition, an operation of determining whether or not to continuously reflect key data to be continuously input based on the set preference value will be described.

The control unit 120 extracts preference value values of the continuously input key data when specific key data is continuously inputted through the key input unit 100, It is determined whether key data to be input is reflected or not.

That is, when the current key data for volume increase is continuously input, the preferred range of the key data for the volume increase is 10 to 30 levels, and the currently set volume level is 20 levels, And controls the volume to be adjusted by reflecting the key data for continuously increasing the volume up to level 30 only.

In other words, when the currently set volume level is increased from 20 to 30, the key data for increasing the input volume is stopped to prevent the volume from being increased any more.

That is, when the set value of the corresponding menu item changed according to the continuously input key data is out of the set preference range, the control unit 120 stops reflecting the continuously inputted key data, So that the operation according to the present invention is not performed.

Accordingly, when the user continuously inputs the specific key data, the user can continuously input the key data only within the preferred range. If the user desires to continuously input the key data even after the user leaves the preferred range, You can stop the input of data and re-enter it to perform the desired operation.

As described above, the image display device having the malfunction prevention function according to the embodiment of the present invention sets the limit range and the preference range for continuous key input, thereby blocking the processing of the key continuously input due to the key failure, It is possible to prevent a malfunction that may be caused due to a key failure within a range that does not disturb the viewing, and by providing the user with the key information of the problem, the user can quickly cope with the problem.

As shown in FIG. 5, the control method of the video display device having the malfunction prevention function according to the first embodiment of the present invention as described above first checks key data input from the outside (S100).

When the key data is input from the outside, it is determined whether the key data is input continuously (S110).

If it is determined that the key data is not continuously input, the operation is performed by reflecting the input key data (S120).

If it is determined in step S110 that the key data is continuously input, the number of times the key data is continuously input is counted in step S130.

Subsequently, the number of times of inputting the counted specific key data is compared with the limit range of the corresponding key data (S140).

Then, it is determined whether the number of times of inputting the key data has reached the corresponding limit (S150).

If it is determined in operation S150 that the input number of the key data does not reach the limit, the key data is continuously reflected in operation S160.

If it is determined in step S150 that the input number of the key data has reached the corresponding limit, the key data is not reflected in step S170. That is, when the number of times of reflection of the inputted key data exceeds the preset limit range, the reflection of the key data is stopped.

Then, key data inputted from outside is checked for a predetermined time (S180).

In step S190, it is determined whether new key data other than the key data whose reflection is stopped is input as a result of the check of the input key data.

If the new key data is input (S190), the new key data is reflected to perform the corresponding operation (S200).

If new key data is not input and the corresponding key data whose reflection is stopped is continuously input as a result of the determination (S190), an alert confirmation message including information of the key data whose reflection is stopped is displayed (S210).

At this time, if the key data whose reflection is stopped is continuously input after displaying the warning confirmation message, the key data is continuously ignored.

That is, in the above case, it is determined that the corresponding key is broken, and the operation of the corresponding key is ignored until the repair of the key is completed (until the input state of the corresponding key data is changed) Do not.

Accordingly, in the first embodiment of the present invention, it is determined whether or not key data continuously input based on the limit range is reflected, thereby making it possible to easily determine the failure key without disturbing the user's viewing of the broadcast, have.

As shown in FIG. 6, the control method of the video display device having the malfunction prevention function according to the second embodiment of the present invention first checks the key data input from the outside (S300).

When the key data is input from the outside, it is determined whether the key data is input continuously (S310).

If it is determined that the key data is not continuously input, the operation is performed by reflecting the input key data (S320).

If it is determined in operation S310 that the key data is continuously input, the preferred range of the predetermined key data is extracted in operation S330.

Then, the extracted preferred range is compared with the setting value of the corresponding menu item changed in accordance with the input key data (S340).

Then, it is determined whether the set value of the menu item to be changed is out of the extracted preferred range (S350).

If the set value of the changed menu item is not out of the extracted preferred range, the set value of the corresponding menu item is changed by continuously reflecting the input key data at step S360.

If it is determined in step S350 that the changed menu item is out of the extracted preferred range, the reflected key data is not reflected and the set value of the corresponding menu item is not changed any more ).

At this time, if the input of the stopped key data is stopped and then re-input, the setting value of the corresponding menu item is changed by reflecting the key data again.

In other words, when the user desires to set the setting value of a specific menu item to a value outside the preferred range, he must re-enter at least one key data.

The control method of the video display device having the malfunction prevention function according to the embodiment of the present invention sets the limit range and the preference range for the continuous key input to block the processing of the key continuously input due to the key failure, It is possible to prevent a malfunction that may be caused due to a key failure within a range that does not disturb the broadcast viewing and also provides the user with the key information of the problem so that the user can quickly cope with the problem.
