A general configuration for audio processing of a television includes a key input unit, a microcomputer, a tuner unit, a voice signal processing unit, an amplifier unit, and a speaker.

The key input unit includes a plurality of keys for operating the television, such as a volume up / down key for adjusting volume up / down and a channel up / down key for channel adjustment. And transmits the key signal corresponding to the key operation to the infrared carrier wave by using a remote controller that can input remotely.

The main body of the television demodulates, detects and amplifies the received infrared carrier wave and applies it to the microcomputer. The microcomputer controls each component in accordance with the key signal of the key input unit to control the overall operation of the television. / Down key signal is applied, a volume control signal of pulse width modulated pulse width modulation (PWM) signal type for up / down the preset level of the volume level is outputted to the amplifying unit to increase the volume of the audio outputted to the speaker / Down.

The audio signal processor detects the audio signal from the intermediate frequency signal applied from the tuner unit, demodulates the audio intermediate frequency signal, processes the audio intermediate frequency signal into an outputable signal, and applies it to the amplification unit.

The amplifying unit 50 amplifies and outputs the audio signal applied from the audio signal processing unit to the speaker, and amplifies and adjusts the volume of audio output based on the volume control signal of the microcomputer.

In recent years, there are many cases where a content device (for example, a smart phone, a set-top box, etc.) is connected to an audio output device such as a television or a speaker to hear the sound. In this case, the volume output from the sound output device is a volume obtained by multiplying the volume of the contents device and the volume of the sound output device.

That is, when the volume of the content device is set to 100% and the volume of the sound output device is set to 50%, a volume of 50% is the final output. On the contrary, the volume of the content device is set to 100% If the volume of the output device is set to 50%, then 50% of the volume will be the final output.

On the other hand, when the volume of the sound output apparatus is set to 100%, the final output will be as it is by adjusting the volume of the contents apparatus. However, when the external input of the sound output apparatus is changed, It is inconvenient to readjust the volume.

On the other hand, recent digital television receivers also support multi-channel audio output for home theater configuration.

In such a home theater system, configuring the output of the audio device optimally is a very important factor for ensuring three-dimensional and realistic sound. In order to maximize the performance of the multi-channel audio system, it is important to determine the position of a plurality of speakers and to set the volume of each speaker to a certain level.

Since the viewer sits on the front of the TV and the viewing sensation is different according to the position of the rear speaker when watching, it is a condition for enjoying a powerful and grand sound to be installed in a proper position.

The existing speaker setup method is to install the speaker in a proper position after listening to the sound and change the position, or to listen to one person to adjust the position and to change the position of one person.

However, when a user views a digital broadcast using a digital television or constructs a speaker system to configure a home theater, it is inconvenient to manually adjust the output of each speaker according to the position to be watched by the user.

In addition, when the arrangement of the speakers is changed or the position of the viewer is changed due to the restriction of the installation space, the output of each speaker must be changed to a new value, There is a hassle to do.

The volume control unit 210 selects a volume output from the speaker 120 of the television 100 and generates a volume control signal corresponding to the selected volume. The volume control unit 210 includes a volume control button . The remote control 200 is provided with a variety of selection and operation buttons for selecting an external input or a channel, as well as the above-described volume control buttons.

The volume setting unit 220 generates a volume setting signal for setting the volume output from the speaker 120 of the television 100 to correspond to the volume selected through the volume control unit 210. [

The volume setting unit 220 may generate a volume setting signal only through a user's operation. However, in this embodiment, for convenience, the communication unit of the remote controller (or the controller of the contents apparatus including the smart phone) And a volume setting signal is generated. At this time, the controller of the remote controller controls to immediately output the volume setting signal generated through the communication unit.

That is, the volume correction is completed before the user inputs the operation signal, such as playing the content through the remote controller. After the operation signal is inputted, the volume corresponding to the volume selected by the user by the volume correction process And output through the speaker 120 of the television 100. [

Also, the volume setting unit 220 is configured to generate a first volume setting signal at a time when a communication unit of the remote controller is connected to a television receiver, and then generate a subsequent volume setting signal at each set interval, So that it is immediately outputted whenever a volume setting signal is generated.

As described above, setting the volume setting signal to be periodically output is not limited to the remote controller, that is, the output of the television speaker may be changed by the user adjusting the output of the television speaker without going through the controller of the contents apparatus, When the volume is changed, it is sensed in real time and the output setting ratio of the speaker is recalculated through a calculation unit described later.

The communication unit 230 transmits the volume control signal generated by the volume control unit 210 and the volume control signal generated by the volume setting unit 220 under the control of the control unit 270. It is preferable that the volume setting signal output from the communication unit 230 includes sound signal information of an ultrasonic band corresponding to an area of the non-audible range that the user can not hear, so that the sound of the ultrasonic band is also transmitted to the speaker 120 Do.

For example, if the reference volume is 100 dB and the reception volume is 80 dB, the output setting ratio of the speaker 120 of the television 100 through calculation is calculated to be 80%. As another example, when the reference volume is 90 dB and the reception volume is 63 dB, the output setting ratio of the speaker 120 of the television 100 is calculated as 70%.

The volume correcting unit 260 corrects the volume output from the speaker 120 of the television 100 by using the output setting ratio value of the speaker 120 of the television 100 calculated by the calculating unit 250, Generates a volume correction signal so as to correspond to the selected volume.

For example, when the volume of the volume adjustment signal generated by the user is 100 dB and the reception volume is 80 dB, the volume value X of the volume correction signal generated by the volume correction unit 260 is (100 + X) * 0.8 = 100 becomes 25 dB.

The volume value X of the volume correction signal generated by the volume correction unit 260 is 110 (110 + X) * 0.8 = 110 27.5 dB . In this way, when the volume is increased from 110 dB to 120 dB, the volume correction signal volume is 30 dB. When the volume correction signal is increased from 120 dB to 130 dB, the volume correction signal is 32.5 dB.

When the user selects the volume control unit 210 and adjusts the volume, the controller 270 generates a volume control signal by adding the volume value of the volume correction signal to the volume value of the selected volume control signal, A volume signal corresponding to a volume value corresponding to the sum of the volume value set for each volume control level and the volume value corresponding to the volume correction signal so that the volume corresponding to the selected volume is output from the speaker 120.

That is, when the volume of the volume adjustment signal generated by the user is 100 dB and the reception volume is 80 dB, the controller 270 sets 25 dB, which is the volume value of the volume correction signal generated by the volume correction unit 260, The volume control signal corresponding to the summed 125 dB is generated and controlled to be transmitted.

Alternatively, the controller 270 may utilize a look-up table in which the volume value of the volume correction signal corresponding to the volume selected by the user is previously data, and may alternatively be used by the calculator 250 and the volume corrector 260 ), And may use the acquired information.
