It includes a level converting unit for converting and applying to the control unit and a microphone used as a transmitter during a telephone call. In addition, the TV according to the present invention uses an existing TV speaker as a telephone receiver.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention. 1 is a block diagram showing a TV device having a telephone function according to the present invention.

As shown, in the device of the present invention, a key input unit 11 such as a remote control having a numeric key for selecting a function of TV / telephone and making a telephone call is connected to the control unit 12. The control unit 12 is connected with level converters 13 and 14 for converting an applied signal into a signal of a predetermined level and outputting the converted signal. In addition, the control unit 12 includes a switch unit 15 for selecting one of several possible operations according to the control signal of the control unit 12, and a voice signal interconnected and applied to the switch unit 15. And an amplifier 16 for adjusting sound quality. The amplifier 16 is connected to the conventional TV speaker 17 used as a handset of the telephone and the microphone 18 used as a talker is formed. The operation of the TV device having a telephone function according to the present invention configured as described above will be described in more detail.

When a call is received while watching TV, a signal for the incoming call is applied to the first level converting unit 13. The first level converting unit 13 converts the applied signal into a signal that can be recognized by the control unit 12 and outputs it to the control unit 12. The control unit 12 receives a signal output from the first level converting unit 13 and applies a control signal to the switch unit 15 and the amplifying unit 16. First, the controller 12 applies a mute signal to the amplifier 16 to mute the TV sound using a TV volume control port (Port 1). At this time, the controller 12 controls the amplifier 16 to operate the TV screen normally and to mute only TV sound. The amplifier 16 receives the TV sound mute signal and does not output the TV sound to the speaker 17. In addition, the control unit 12 applies a constant signal to the amplifier 16 such as a ring tone for notifying that a call is received by using a sound control port (Port 2). The amplifier 16 outputs a ring tone to the speaker 17 by adjusting the amplified and sound quality of the received signal. The TV viewer hears this ringtone while watching TV and finds out that the call is coming. The viewer switches to the telephone function by using a key input unit 11 such as a remote controller to answer the call. When the telephone function is selected, the control unit 12 applies a signal received from the first level converting unit 13 to the switch unit 15 using a switch control port (Port 3). The switch unit 15 outputs the applied signal to the amplifier 16. The amplifier 16 adjusts the voice amplification and the sound quality of the received signal and outputs it to the speaker 17. The viewer listens to the other party with the sound output through the speaker 17 and responds through the microphone 18. The voice of the responding viewer is applied to the amplifier 16 through the microphone 18. The amplifier 16 adjusts the audio signal to be applied to the switch unit 15. The switch unit 15 transmits the authorized voice signal to the counterpart phone via the telephone line. In this way, the viewer during the TV viewing talks on the incoming call. When the viewer wants to watch TV after the call, the TV normally operates when the viewer switches to the TV function using the key input unit 11. That is, the control unit 12 receiving the TV function selection signal of the key input unit 11 controls the TV sound properly through the port 1 to output the speaker 17 to perform the normal TV operation. do.

This time, let's explain how the viewer wants to make a call while watching TV. When the viewer selects the telephone function through the key input unit 11, the control unit 12 applies the TV sound mute signal to the amplifying unit 16 through Port 1. Of course, the control unit 12 also controls the amplifier 16 so that the TV screen operates normally and only mutes the TV sound. Thus, the amplifier 16 receiving the TV sound mute signal does not output the TV sound to the speaker 17. Further, the viewer switches to the telephone function by using the key input unit 11, and then selects the numeric keys of the key input units 11 to 9 and presses the other party's telephone number. The controller 12 recognizes a signal of the selected numeric key and outputs the signal to the second level converter 14. The second level converting unit 14 converts the received signal into a signal that can be transmitted through the telephone line and transmits the signal to the telephone line. In this way, the other party's phone is signaled and the viewer can make a phone call with the other party. That is, the signal for the other party's phone is applied to the first level converting unit 13 via the telephone line. The first level converter 13 converts the received signal into a signal that can be recognized by the controller 12 and outputs the signal to the controller 12. The control unit 12 outputs the received signal to the switch unit 15 using Port 3. The switch unit 15 outputs the applied signal to the amplifier 16. The amplifier 16 outputs the received signal to the speaker 17 by adjusting the voice amplification and sound quality. The viewer hears the sound output from the speaker 17 and makes a phone call with the other party. In addition, the voice of the responding viewer is applied to the amplifying unit 16 through the microphone 18. The amplifier 16 adjusts the audio signal to be applied to the switch unit 15. The switch unit 15 transmits the authorized signal to the counterpart phone via the telephone line. In this way, the viewer can call while watching TV. If the viewer wants to watch TV after the call, the TV operates normally by switching to the TV function using the key input unit 11. That is, the control unit 12 receiving the TV function selection signal of the key input unit 11 controls the TV sound properly through the port 1 to output the speaker 17 to perform the normal TV operation. do. Through this process, the viewer can finish the phone call and watch TV.

2 is a flowchart illustrating the operation of a TV apparatus having a telephone function according to the present invention. If the viewer selects a function change through the key input unit 11 while watching TV, the control unit 12 checks whether the selected function change is a phone function selection (step 201). If the telephone function is not selected, step 202, that is, the TV operates normally under the control of the controller 12. FIG. If the telephone function is selected, the controller 12 recognizes that a call is made or a viewer makes a call (step 203). Thus, the control unit 12 mutes the sound of the TV (step 204). At this time, the TV screen performs the operation as it is. The control unit 12 switches the TV function to the telephone function so that the viewer can make an incoming call or make a telephone call (step 205). After the telephone call is finished (step 206), the viewer selects a desired function change using the key input unit 11. That is, the TV function for TV viewing or the phone function for telephone call is selected. When the function change selection signal is input to the key input unit 11, the control unit 12 recognizes this and sequentially executes the operation from step 201. As steps 201 to 207 are repeatedly performed, the viewer can receive an incoming call while watching TV and can also make a call.

As described above, the present invention relates to a TV device having a telephone function.

Therefore, when watching TV using this TV device, the incoming call during the TV viewing can be received while watching TV, and the convenience of the telephone call can be made while watching TV.
