Referring to Figure 2 the operation of the present invention configured as described above is as follows.

Referring to FIG. 2, the television antenna 10 receives a composite video signal transmitted from a broadcasting station. The composite video signal received by the antenna 10 is tuned to the broadcast channel that the user wants to watch in the tuner unit 15. The composite video signal tuned by the tuner 15 is detected by the IF detector 15 at an intermediate frequency, and is separated into a video signal and an audio signal by the P / S separator 25. The video signal among the video signal and the audio signal separated by the P / S separator 25 is image-processed into a video signal suitable for output to the CRT 40 by the image processor 30. The image signal processed by the image processor 30 is amplified by the image output unit 35 and displayed through the CRT 40. The audio signal among the video signal and the audio signal separated by the P / S separation unit 25 is voice processed into an audio signal suitable for output from the audio processing unit 45 to the television speaker 55. The voice signal processed by the voice processor 45 is amplified by the voice output unit 50 and output to the outside through the television speaker 55. In addition, the voice signal separated by the P / S separation unit 25 is applied to the FM modulator 60 is modulated into a signal suitable for wireless transmission. The voice signal modulated by the FM modulator 60 is wirelessly transmitted by the voice signal transmitter 65 and applied to the wireless voice receiver. In addition, the user inputs a key to turn off the power of the television through the key input unit 70, to stop the operation of the wireless voice transmitter, or to switch the main screen to the sub screen through the PIP screen in the case of PIP television. In such a case that the operation of the radio receiver is unnecessary, the key command signal is applied to the TV microcomputer 75. When the TV microcomputer 75 receives the command signal, the operation of the wireless voice receiver is no longer necessary. Therefore, the TV microcomputer 75 controls the control signal emitter 80 to wirelessly transmit the wireless voice receiver power-off control signal to the wireless voice receiver. Is authorized. On the other hand, the unvoiced voice signal transmitted from the television wireless voice transmitter is received through the receiving antenna 85 of the wireless voice receiver. The wireless voice signal received through the reception antenna 85 is wirelessly received by the voice receiver 90. The voice signal wirelessly received by the voice receiver 90 is detected as a signal suitable for output by the FM detector 95. The voice signal detected by the FM detector 95 is amplified by the voice amplifier 100 and output through the receiver speaker 105. In addition, a power-off control signal applied wirelessly from the control signal emitting unit 80 of the wireless voice transmitter of the television is received by the control signal receiving unit 110 of the wireless voice receiver. The power off control signal received by the control signal receiver 110 is applied to the receiver microcomputer 115, and the receiver microcomputer 115 controls the switching unit 120 according to the power off control signal to the wireless voice receiver. The power supply unit 125 for supplying power is turned off to cut off the supply power.

Referring to the detailed flowchart of the operation of the wireless voice transmitter and receiver having the automatic power off function of the television in the above process as follows.

3 is a flow chart for explaining the operation of the wireless voice transmitter and receiver having an automatic power off function of a television.

Referring to FIG. 3, the television unvoiced voice transmitter wirelessly applies a voice signal to the wireless voice receiver through the voice signal transmitter 65 (S100).

In step S100, the TV microcomputer 75 determines whether the current mode is a mode in which the wireless voice signal does not need to be applied to the wireless voice receiver (S200).

According to the result determined in step S200, if it is necessary to continue to apply the wireless voice signal, repeat the step S200, and if the mode does not need to apply the wireless voice signal, the receiver microcomputer 115 is a control signal light emitting unit ( The control unit 80 applies the power-off control signal to the wireless voice receiver (S300).

The power-off control signal applied in step S300 is received by the control signal receiving unit 110 of the wireless voice receiver (S400).

The power-off control signal received in step S400 is applied to the receiver microcomputer 115, and the receiver microcomputer 115 controls the switching unit 120 to turn off the power of the power supply unit 125 (S500).

When the power of the power supply 125 is off in S500, the power supplied to the wireless voice receiver is cut off (S600).

Through all the above process, as the present invention intends, a wireless voice transmission / reception device having an automatic power off function is implemented.

As can be seen from the above description, the present invention, in order to save the power of the wireless voice receiver, when the operation of the unvoiced voice receiver is unnecessary mode, for example, to turn off the power of the television, In case of stopping the operation of the transmitter or switching the main screen to the sub screen through the PIP screen in case of PIP television, when the power off control signal is applied to the wireless voice receiver to turn off the power, the operation of the wireless voice receiver is unnecessary. It is possible to save power by solving the waste of power that can be generated by turning on the device automatically by turning off the power.
