Description

TV volume control method in digital broadcasting receiver {METHOD FOR CONTROLLING INCREASE OF VOLUME IN A DIGITAL BROADCASTING RECEIVER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcasting receiver, and in particular, when there is an abnormal continuous increase key input of the TV volume by an infant or a child who is not perceptible in the digital broadcasting receiver, the TV volume does not increase above a certain threshold. The present invention relates to a TV volume control method in a digital broadcasting receiver which prevents noise from damage caused by an abnormal increase in TV volume.

In general, a digital broadcast receiver called a set top box is a device configured with a TV receiver to receive various TV image data of multiple channels transmitted through a network or a satellite. Receives digital broadcasting data compressed by a moving picture experts group (MPEG) -2 method, and transmits the compressed data, decodes the encoded data, and converts the encoded data into a standard NTSC signal to be displayed on a TV receiver.

That is, the digital broadcast receiver receives a bit-stream digital broadcast signal in a packet unit transmitted from a broadcasting station, and selects a channel selected from among the broadcast signals received by transport demux. The broadcast signal is extracted, and the extracted broadcast signal is decoded by the MPEG-2 scheme and then displayed.

On the other hand, in the TV volume increase in the digital broadcast receiver, at present, the user presses the key of the TV volume up / down key from a key input unit or a remote controller provided in the front panel of the digital broadcast receiver. If there is an input, the TV volume is increased indefinitely without any restriction depending on the input of the TV volume increasing key.

Accordingly, when an infant or a child who has no perception ability plays with the remote control and enters the TV volume increasing key by mistake or mischief in a row, the TV volume increases abnormally quickly and causes noise. If you are surprised by the abnormally increased TV volume noise and various safety problems were caused.

Therefore, the present invention, when there is an abnormal continuous increase key input to the TV volume by the infant or child without the perceptual ability in the digital broadcast receiver to pause the TV volume does not increase more than a certain threshold noise due to abnormal TV volume increase It is intended to provide a TV volume control method in a digital broadcasting receiver that does not cause damage.

As described above, the present invention provides a method of controlling a TV volume in a digital broadcasting receiver, the method comprising: receiving a key input for increasing the TV volume and increasing the TV volume, and the increasing key input of the TV volume exceeds a preset threshold of the TV volume. Checking whether the input is continuously performed; stopping the increase of the TV volume when the increase key input is continuously input so as to exceed the threshold value; and after stopping the increase of the TV volume, the increase key. Checking whether an input is input, and increasing the TV volume above the threshold when the increase key input is paused and then received again.

In another aspect, the present invention provides a method for controlling the TV volume in a digital broadcasting receiver, the method comprising: receiving a key input for increasing the TV volume and increasing the TV volume, and the increasing key input of the TV volume exceeds a preset threshold of the TV volume. Checking whether the input is continuously performed, stopping the increase of the TV volume when the increase key input is continuously input so as to exceed the threshold value, and after stopping the increase of the TV volume, Requesting input of a preset key for increasing the volume above the threshold, and increasing the TV volume above the threshold when the value of the key input according to the request matches the value of the preset key. It comprises the step of.

The present invention provides a method for controlling TV volume in a digital broadcasting receiver, wherein a preset step threshold is set to prevent TV volume increase keys from being abnormally increased due to continuous input of a TV volume increase key by an infant or child having low perceptual ability. Noise pauses caused by abnormal TV volume increase by pausing the TV volume increase from the value, and then increasing the TV volume above the threshold by receiving the input of the TV volume increase key again or receiving a preset password or a specific key input. There is an advantage that does not occur. In addition, there is an advantage that can prevent infants or young children from being surprised by the abnormally increased TV volume.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the present invention. In the following description of the present invention, when it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be made based on the contents throughout the specification.

Looking at the technical gist of the present invention, through the technology to pause the TV volume does not increase more than a certain threshold when there is an abnormal continuous increase key input to the TV volume by the infant or child without the perceptual ability in the digital broadcast receiver It is easy to achieve what is intended in the present invention.

1 illustrates a detailed block configuration of a digital broadcast receiver to which an embodiment of the present invention is applied.

Referring to FIG. 1, first, the key input unit 118 and the remote controller 126 generate a key data signal according to a user's key operation and apply the generated key data signal to the controller 116. The memory unit 120 stores an operation program for the operation of the digital broadcast receiver, and stores and outputs various program information output from the tuner unit 100 under the control of the controller 116.

The tuner 100 tunes and receives a bit stream of a channel corresponding to the tuning control signal of the controller 116 among the bit streams received from the terrestrial wave or satellite. The channel decoder 102 decodes the signal tuned from the tuner 100 in a manner such as VSB, QPSK, QAM, etc. according to a transmission method, and applies the demultiplexer 104 to the demultiplexer 104.

The demultiplexer 104 receives the digital stream decoded by the channel decoder 102 and divides the digital stream into a video, audio, and additional information stream and applies the decoded stream to the A / V decoder 106. In this case, the A / V decoder 106 may be, for example, an MPEG-2 decoder. Then, the A / V decoder 106 separates and decodes the broadcast signal provided from the demultiplexer 104 into an audio signal and a video signal, and then performs a predetermined signal processing process through the video / audio processing units 108 and 110. The receiver display unit 112 is displayed on the screen.

The video processor 108 receives a video signal decoded and output from the A / V decoder 106 and converts the video signal into a displayable image signal on a screen of the display 112 of a TV receiver such as a CRT, a PDP, an LCD, or the like. The audio processor 110 receives the audio signal decoded and output from the A / V decoder 106 and reproduces the audio signal through the audio output unit such as the speaker 114. The IR receiver 124 receives an operation command of a remote controller operated by a user and applies it to the controller 116.

The controller 116 controls the overall operation of each part of the digital broadcast receiver according to the operation program stored in the memory unit 120, and the remote controller 126 input from the key data signal from the key input unit 118 and the IR receiver 124. According to the key data from the control signal for generating a corresponding function is generated and applied to the corresponding function. For example, the tuner 100 provides a tuning control signal for tuning a broadcast channel selected by a user, and generates a decoding control signal for decoding the tuned broadcast signal.

In addition, when the TV volume increase key is continuously input and the TV volume reaches a preset step-by-step threshold value, the controller 116 pauses the TV volume increase and then re-enters the TV volume increase key according to an embodiment of the present invention. By authenticating an input or a preset password or input of a specific key, the TV volume is increased above a threshold value so that abnormal TV volume increase by an infant or a child is prevented.

2 is a flowchart illustrating a TV volume control process for preventing an abnormally continuous increase in TV volume in a digital broadcast receiver according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when there is a power-on key input through the key input unit 118 or the remote controller 126, the controller 116 of the digital broadcast receiver turns on the power of the digital broadcast receiver at step S200, and at step S202. In step, the broadcast of the channel previously watched is displayed.

Accordingly, a user may watch a broadcast program of a channel previously watched, or use a key input unit 118 or a remote controller 126 implemented on the front panel of a digital broadcast receiver to watch a channel for broadcasting another desired channel. You can switch to watch another broadcast.

On the other hand, the TV volume provided on the key input unit 118 or the remote control 126 by the infant or child with low perception ability while the digital broadcast receiver is turned on and the broadcast of the channel selected by the user is displayed as described above. It may happen that a key is continuously input.

Then, when the TV volume increasing key is received through the key input unit 118 or the remote controller 126 in step S204, the controller 116 of the digital broadcasting receiver proceeds to step S206. In step S208, it is checked whether the TV volume exceeds a predetermined threshold set by the user.

At this time, the threshold value of the TV volume set by the above user is preset to the TV volume of the level expected to be surprised by noise damage or infants, etc., as shown in FIG. A plurality of threshold values T1, T2, and T3 may be set in stages with volume values of% and 70%.

Subsequently, when the TV volume increases above the threshold in the step of checking the TV volume in step S208 above, the controller 116 proceeds to step S210 to check for an abnormal increase in TV volume caused by an infant or the like. Proceed as to whether or not key input of TV volume increasing key is continuously input.

At this time, if it is checked that the key input of the TV volume increasing key is continuously input through the key input unit 118 or the remote controller 126, the control unit 116 proceeds to step S212 and the TV volume exceeds the threshold value. Temporarily stop increasing the TV volume so that it does not increase.

Subsequently, the controller 116 checks whether the key input of the TV volume increasing key is paused and input again in step S214. This is for a normal user to suspend the input of the TV volume increasing key and then input the TV volume increasing key again when the TV volume stops increasing at a threshold value during continuous input of the TV volume increasing key.

Accordingly, when the TV volume increasing key is input again as described above, the control unit 116 determines that the normal volume is requested by the normal user to watch TV at a large volume, and then thresholds the TV volume in step S216. This will increase the number as you want. However, if the TV volume increase key is continuously input even after the TV volume increase is stopped, the controller 116 determines this as an abnormal key input of a user who does not have the perceptual ability such as an infant to determine the TV volume as the size of the TV volume stop point. It keeps going.

4 is a flow diagram illustrating a TV volume control process for preventing abnormally increasing TV volume in a digital broadcasting receiver according to another embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1, 3, and 4.

First, when there is a power-on key input through the key input unit 118 or the remote controller 126, the controller 116 of the digital broadcast receiver turns on the power of the digital broadcast receiver in step S400, and in step S402. In step, the broadcast of the channel previously watched is displayed.

Accordingly, a user may watch a broadcast program of a channel previously watched, or use a key input unit 118 or a remote controller 126 implemented on the front panel of a digital broadcast receiver to watch a channel for broadcasting another desired channel. You can switch to watch another broadcast.

On the other hand, the TV volume provided on the key input unit 118 or the remote control 126 by the infant or child with low perception ability while the digital broadcast receiver is turned on and the broadcast of the channel selected by the user is displayed as described above. It may happen that a key is continuously input.

Then, when the TV volume increasing key is received through the key input unit 118 or the remote controller 126 in step S404, the controller 116 of the digital broadcasting receiver proceeds to step S406. In step S408, it is checked whether the TV volume exceeds a predetermined threshold set by the user.

At this time, the TV volume threshold set by the user is preset to the TV volume of the level expected to be surprised by noise damage, infants, etc. as described in the operation of FIG. 2 above, as shown in FIG. Likewise, a plurality of threshold values T1, T2, and T3 may be set in stages as volume values that are 30%, 50%, and 70% of the TV overall volume.

Subsequently, when the TV volume increases above the threshold in the step of checking the TV volume in step S408 above, the control unit 116 proceeds to step S410 to check for an abnormal increase in TV volume caused by an infant or the like. Proceed as to whether or not key input of TV volume increasing key is continuously input.

At this time, if it is checked that the key input of the TV volume increasing key is continuously input through the key input unit 118 or the remote controller 126, the control unit 116 proceeds to step S412 and the TV volume exceeds the threshold value. Temporarily stop increasing the TV volume so that it does not increase.

Subsequently, the controller 116 requests input of a preset key to confirm whether the input of the TV volume increasing key for continuously increasing the TV volume above the threshold in step S414 is a normal request. In this case, the preset key may be set as a key of two or more combined password types or one specific key.

Accordingly, in the case of a normal user who wants to watch a broadcast at a higher volume, a password or a specific key is input using the key input unit 118 or the remote controller 126. In this case, the specific key may be preset as one of any keys provided on the key input unit 118 or the remote controller 126 of the digital broadcast receiver.

Then, the control unit 116 receives a password or a specific key input by the user in step S416 and checks whether the password or the specific key input above matches the preset password or the specific key in step S418. do.

In this case, if the password or the specific key input by the user does not match the preset password or the specific key, the control unit 116 returns to step S414 and requests the input of the password or the specific key again.

On the other hand, if the password or the specific key input by the user matches the preset password or the specific key, the control unit 116 proceeds from step S418 to step S420 to allow the user to raise the TV volume above the threshold. You can increase it as desired.

As described above, in the present invention, in the method of controlling the TV volume in the digital broadcasting receiver, the TV volume increasing key is continuously inputted by an infant or a child who has a poor perception ability to prevent the TV volume from being abnormally increased. In order to suspend the TV volume increase at a preset stepwise threshold, the TV volume is increased above the threshold by receiving the input of the TV volume increase key again or receiving a preset password or a specific key. It is possible to prevent an abnormal TV volume increase by a child so that noise damage does not occur, and to prevent an infant or a child from being surprised by an abnormally increased TV volume.
