1 is a block diagram illustrating a detailed block diagram 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 noise measuring unit 122 measures the noise of the surroundings when the digital broadcasting receiver is turned on and applies the noise to 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 to receive a TV receiver. The display unit 112 is displayed on the screen.

The video processor 108 receives the video signal decoded and output from the A / V decoder 106 and converts the video signal into a displayable image signal on the screen of the display unit 112 of the TV receiver such as a CRT, PDP, LCD, etc. 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, the control unit 116, in the digital TV receiver according to an embodiment of the present invention, in the initial TV volume automatic adjustment, according to a condition set by the user, the specific time of the night or the morning when the TV sound may be damaged by noise By adjusting the initial TV volume to a low volume level automatically or by setting the TV volume proportionally according to the ambient noise, the TV volume of the digital broadcasting receiver is automatically adjusted to a low volume level at night or in the morning. Minimize the damage caused by noise.

2 is a flowchart illustrating an operation control for adjusting an initial TV volume according to a preset condition in a digital broadcasting receiver according to an exemplary embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when the user wants to set the TV volume output when the digital broadcasting receiver is turned on to be low in a certain time zone such as a night time zone or a morning time zone, or when another person is sleeping, in the desired time zone in the TV volume setting mode. This will set the initial TV volume.

That is, when the TV volume setting mode is selected, the controller 116 of the digital broadcast receiver proceeds to step S202 and receives specific time zone information for setting the TV volume in response to step S202.

Subsequently, the controller 116 receives the TV volume information to be set in the specific time zone input in step S204, and proceeds to step S206 to set the TV volume information input by the user in the specific time zone. . In this case, the specific time zone may be mainly set as a late night time between 22 and 02:00 or a morning time between 06 and 08:00.

As described above, when a power-on is requested by the user while the initial TV volume is set in a specific time zone, the control unit 116 proceeds to step S210 in response to this in step S208 and powers on by the user. It is checked if this requested time point is included in the specified time zone for the initial TV volume.

In this case, if the requested time to turn on the power is not included in the specific time zone set by the user, the control unit 116 proceeds from step S212 to step S214 to check the TV volume previously set at the time of viewing. In operation S216, an audio signal of the broadcast program is output at the confirmed TV volume at the time of viewing.

However, in contrast, when the power-on request time is included in the specific time zone set by the user, the control unit 116 proceeds from step S212 to step S218 to check the TV volume set in the specific time zone. Thereafter, in step S220, for example, at a specific time zone set as a late night time or a morning time, the audio signal of the broadcast program is output at a predetermined low TV volume instead of the TV volume previously watched.

At this time, the TV volume, which is set to prevent noise generation or disturb other people's sleep in a specific time zone set for late night time or morning time, may be set in the range of 5 to 10 percent of the total TV volume, for example. In addition, as the audio signal is output at such a low TV volume, it is possible to minimize the noise damage caused by the TV sound of the digital broadcasting receiver at night or in the morning.

3 is a flowchart illustrating an operation control for adjusting an initial TV volume according to a preset condition in a digital broadcasting receiver according to another embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 3.

First, if the user wants to set the TV volume output when the digital broadcasting receiver is turned on to be low in a certain time zone such as a late night time or a morning time, or when someone is sleeping, Set the initial TV volume accordingly.

At this time, when setting the TV volume according to the ambient noise, the user sets the noise that can occur at each time zone in the home divided by a step range, and then set the initial TV volume to be proportional to the stepped noise range. That is, the TV volume is set to be very small in proportion to the noise at a time when the ambient noise is small, such as late night time or morning time, so that the damage caused by the TV volume does not occur.

Accordingly, when the TV volume setting mode according to the noise is selected, the controller 116 proceeds to step S302 in response to step S302 and inputs TV volume information input for each noise level in response to step S302. Set the initial TV volume according to the noise.

Subsequently, when power-on is requested by the user in a state where the initial TV volume according to the ambient noise is set as described above, the controller 116 proceeds to step S306 in response to the operation at step S304 and the noise measuring unit 122 is performed. Measure the ambient noise with).

Subsequently, the controller 116 checks initial TV volume information of a preset noise range corresponding to the noise measured in step S308, and then outputs an audio signal of a broadcast program at the TV volume checked in step S310.

Accordingly, when the noise is measured at a low time such as a late night time or a morning time, the audio signal of the digital broadcast receiver is output at a low TV volume in proportion to the level of the noise. The noise damage caused can be minimized.

As described above, in the present invention, in the method of adjusting the initial TV volume in a digital broadcasting receiver, the initial TV volume is automatically adjusted to a low volume level at a specific time of night or in the morning when the TV sound may be damaged by noise. Alternatively, the TV volume is set proportionally according to the ambient noise, so that the TV volume is automatically adjusted to a low volume level at night or in the morning, thereby minimizing the noise damage caused by the TV sound of the digital broadcasting receiver.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.
