Hereinafter, the operation of the present invention will be described with reference to FIGS. 2 and 3.

It is confirmed whether the user has turned on the power key PWR of the key input unit 1 or the remote controller 2 in step 31. If the user turns on the power key PWR in step 31, ).

In the microprocessor 3 supplied with power, the user confirms whether or not a desired channel is touched while turning on the channel up / down key CH (step 33). If the user has turned on, the television broadcast signal of the channel selected by the user is selected And outputs the phase control signal to the phase lock loop 5 so that the tuner 6 selects a desired television broadcast signal among the various television broadcast signals received through the antenna 7 (step 34).

The television broadcast signal selected by the tuner 9 is mixed with the output of the local oscillator 9 in the intermediate frequency amplifier 8 to be amplified and detected and output as an intermediate frequency signal of a constant frequency, The voice signal output from the speaker 8 is detected by the voice detector 10 and amplified by the next amplifier 12 via the first switching IC 11 so as to be heard through the speaker 13 (Step 35). The video signal separated and output from the intermediate frequency amplifier 8 is detected by the video detector 14 and is processed by the signal processor 16 through the second switching IC 15 And outputs the image signal to the monitor 20 through the color demodulator 18 and the CRT driver 19 (step 36).

If the user confirms whether the storage / playback key S / P is turned on through the key input unit 1 or the remote controller 2 (step 37), the microprocessor 3 controls the wide angle camera 21 (Step 38). The CCD image sensor 22 generates and outputs an electrical signal according to the amount of light received through the wide-angle camera 21, and outputs the electrical signal to the CCD image sensor 22, and generates a complete image signal for the image. The analog image signal is converted from a first analog / digital converter 24 to a digital signal And stored in the area of the memory 27 (step 39).

At the same time, the user's voice is converted into an electrical voice signal by the microphone 25, converted into a digital signal through the second analog / digital converter 26, and stored in the memory 27 (step 40).

Then, the user recognizes whether the storage / playback key S / P is turned on (step 42) while the television is turned on (step 41).

When the storage / playback key S / P is turned on again, the image message of the image signal and the audio signal stored in the memory 27 is read (step 43), and the image signal is read out from the second digital- Converted into an analog signal and input to the second switching IC 15. The second switching IC 15 receives the control signal from the second switching IC 15 under the control of the microprocessor 3, Through the monitor 18 and the CRT driver 19, through the monitor 20 (step 44).

At the same time, the voice signal read out from the memory 27 is converted into an analog voice signal by the first digital-to-analog converter 28 and input to the first switching IC 11, 1 switching IC 11 through the amplifier 12 and through the speaker 13 (step 45).

Therefore, according to the message transmitting apparatus and method using the television of the present invention, when the user turns on the storage / reproducing key, the image signal corresponding to the image message is input through the wide angle camera of the television, And stores the voice signal in the memory. When the user turns on the storage / reproducing key again, the video message stored in the memory can be confirmed through the television screen and the speaker.
