    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    2 is a block diagram illustrating a configuration of a volume balance adjusting device of a television according to an embodiment of the present invention.
    As shown in FIG. 2, the apparatus for adjusting the volume balance of a television according to an embodiment of the present invention includes an antenna 1, a tuner 2, an IF amplifier 3, a P / S separator 4, Image detector (5), image processor (6), CRT driver (7), CRT (8), voice detector (9), stereo voice processor (10), R audio amplifier (11), L audio amplifier 12, an R speaker 13, an L speaker 14, a remote controller 15, a receiver 16, a controller 17, a memory 18, and a volume balance key 19.
    The volume balance key 19 is configured to set the adjustment of the R and L volume balance for adjusting the R and L volume balance output through the R and L speakers 13 and 14, and is configured in the television or the remote controller 11 Is composed in
    The memory 18 stores not only the current volume set by the viewer, but also the R and L volume balance data (in detail, the data of which the R and L volumes varying according to the volume are accurately measured and preset). .
    The controller 17 loads the current volume stored in the memory 18 when the adjustment of the R and L volume balance is set in the television on state, that is, when the volume balance key 19 is on. Based on the R and L volume balance data according to the volume, compare the magnitudes of the R and L volumes according to the current volume loaded, and as a result of the comparison, if the R volume is larger than the L volume, the difference between the R volume and the L volume is corrected. If the volume is increased and the R volume is less than the L volume, a control signal for increasing the R volume is output so as to be corrected by the difference between the R volume and the L volume.
    The stereo audio processor 10 performs audio processing of the stereo audio signal detected by the voice detector 9 under the control of the controller 17, and outputs R and L audio signals to output the R and L audio amplifiers 11, 12) and the R and L speakers 13 and 14 output the R and L volumes at the optimum balance, respectively.
    The volume balance adjusting device of the television according to the present invention configured as described above has the R and L volumes in the controller 17 when the television is turned on by the viewer and the current volume is stored in the memory 18 by the controller 17. It is determined whether the adjustment of the balance is set, that is, whether the volume balance key 19 is on, and when the volume balance key 19 is on, the current volume stored in the memory 18 is loaded and then stored in the memory 18. Based on the R and L volume balance data according to the volume, the R and L volumes according to the loaded current volume are compared.
    As a result of the comparison, when the R volume is greater than the L volume, the control unit 17 outputs a control signal for increasing the L volume by the difference between the R volume and the L volume, while the R volume and the L volume are smaller than the L volume. A control signal for increasing the R volume by the difference in volume is output.
    Accordingly, the stereo audio processing unit 10 performs the audio processing of the detected stereo audio signal from the audio detector 9 to output the R and L audio signals, thereby outputting the R and L audio amplifiers 11 and 12 and R. Through the L speakers 13 and 14, the R and L volumes are respectively output at the optimum balance.
    On the other hand, instead of configuring the volume balance key on the remote control or the television to set the R, L volume balance adjustment through the volume balance key, the volume balance mode is configured in the sub menu so that the viewer selects the main menu. When the volume balance mode is selected, the R and L volume balance may be automatically adjusted.
    3 is a flowchart illustrating a configuration of a volume balance adjusting method of a television according to an embodiment of the present invention.
    In step S1 of FIG. 3, it is determined whether the main power supply of the television is on. In step S1, when the main power supply of the television is on, it is determined whether the television is on. If the television is in the on state in step S2, it is determined in step S3 whether the volume balance key is in the on state.
    That is, when the television is turned on while the main power of the television is on, and the current volume is stored in the memory by the controller, the controller determines whether the adjustment of the R and L volume balance is set, that is, the volume balance key is on. .
    If the volume balance key is on in step S3, the current volume is loaded in step S4, the current volume is loaded in step S4, and R according to the current volume loaded in step S5; The volume of R and L volume of L volume balance data is compared.
    That is, when the volume balance key is in the on state, the control unit loads the current volume stored in the memory 18 and then R according to the volume stored in the memory 18, and R according to the current volume loaded based on the L volume balance data. Compare the volume of the L volume.
    Compare the magnitudes of the R and L volumes in step S5, if the R volume is greater than the L volume, increase the L volume in step S6, and if the R volume is less than the L volume, increase the R volume in step S7. Increase.
    That is, if the R volume is greater than the L volume, the control unit outputs a control signal for increasing the L volume by the difference between the R volume and the L volume, while if the R volume is smaller than the L volume, the R is equal to the difference between the R volume and the L volume. By outputting a control signal to increase the volume, the stereo voice processor performs voice processing of the detected stereo voice signal from the voice detector, and the R, L voice amplification unit and the R, L speakers achieve optimal balance of R, L. The volume will be output respectively.
    When the L volume is increased in step S6, when the R volume is increased in step S7, when the R volume is equal to the L volume in step S5, the main power source of the television is turned on in step S1. If it is not in the state, when the television is not on in step S2, and when the volume balance key is not on in step S3, it is determined in step S8 whether the main power of the television is off. When the main power supply of the television is not in the off state, the process returns to step S2. When the main power supply of the television is in the off state, the operation of the television is terminated.
    That is, when the L volume is increased, when the R volume is increased, when the R volume is equal to the L volume, when the main power supply of the television is not turned on, when the television is not turned on, and the volume balance key is turned on. If it is not in the state, the control unit then determines whether the main power of the television is in the off state, and if the main power of the television is not in the off state, determines whether the television is in the on state and performs the corresponding operation. In the off state, the operation of the television is terminated by the controller.
    According to the configuration and operation of the apparatus and method for adjusting the volume balance of the television according to the embodiment of the present invention described above, the R volume is compared by comparing the magnitudes of the R and L volumes of the R and L volume balance data according to the current volume. If larger, the L volume is increased, while if the R volume is smaller than the L volume, the R volume is increased to automatically adjust the R and L volume balance according to the current volume.
