There may be a plurality of embodiments of the present invention. Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. This embodiment allows for a better understanding of the objects, features and advantages of the present invention.

As shown in the block diagram of FIG. 1, a television having a telephone function according to the present invention includes a broadcast signal processor 101, a user setup unit 102, a telephone extension port 103, a caller detector 104, and a ring detector. 105, a control unit 106, a program storage unit 107, an OSD processing unit 108, an image output unit 109, a sound output unit 110, and a sound input unit 111.

The broadcast signal processor 101 receives a broadcast signal from an antenna and processes the broadcast signal from the antenna so as to output a video signal and an audio signal through the video output unit 109 and the audio output unit 110 of the television.

The user setting unit 102 may be implemented by an operation panel or a remote controller provided in a normal television, and the user may set a telephone function and an operation mode.

The telephone extension port 103 is connected to a trunk line connected to a public telephone network and a telephone line connected to a telephone.

The caller detector 104 detects caller phone number information received on a ring signal through a trunk line connected to the phone extension port 103.

The ring detector 105 detects a ring signal received through the trunk line connected to the telephone extension port 103.

The control unit 106 controls the overall operation of the telephone function based on the reception / output function of the broadcast signal and the telephone function operation program stored in the program storage unit 107 according to the user's command input through the user setting unit 102. do.

The program storage unit 107 stores a telephone function operation program for operating a telephone function that can be set through the user setting unit 102.

The OSD processing unit 108 generates the caller phone number information detected by the caller detecting unit 104 as an OSD signal according to a control signal of the controller 108 and outputs the OSD signal through the image output unit 109.

The video output unit 109 outputs the video signal processed by the broadcast signal processor 101 to the outside, and outputs an OSD screen by the OSD processor 108.

The sound output unit 110 outputs the sound signal processed by the broadcast signal processing unit 101 to the outside, and outputs the sound signal received through the trunk line connected to the telephone extension port 103.

The sound input unit 111 transmits a sound signal input from the outside through a trunk line connected to the phone expansion port 103.

Hereinafter, in describing an operation process of a television having a telephone function according to the present invention configured as described above, since the reception / output function of a broadcast signal corresponds to a known technical idea, the description thereof will be omitted, and a telephone function setting process and An implementation process will be described with reference to FIGS. 1 to 3.

First, when the user setting mode is selected through the user setting unit 102 and the telephone function is selected, the control unit 106 drives the telephone function operation program stored in the program storage unit 107 (S201 to S202).

Thereafter, the OSD processing unit 108 outputs an OSD screen for setting the caller ID display method through the image output unit 109 according to a control signal of the control unit 106 by the telephone function operation program, and the user displays the OSD screen. The caller ID display method is set in the same manner as in the normal function setting (channel setting, screen mode setting, etc.). At this time, the user can set the position and size of the screen on which the caller's telephone number is to be displayed (S203).

In addition, according to the control signal of the control unit 106 by the telephone function operation program, the OSD processing unit 108 outputs an OSD screen through the image output unit 109, which can set the sound output restriction method during the phone call, the user While setting the OSD screen, the sound output restriction method is set in the same manner as the setting procedure for the caller ID display method. At this time, the user may set whether to automatically adjust the output sound level of the broadcast signal to a predetermined level or turn off the output function of the broadcast signal when the phone call (S204).

As described above, when the user setting procedure through steps S201 to S204 is completed, the television is placed in a telephone standby mode, and when a ring signal is received from a trunk line connected to the telephone extension port 103, the ring detector 105 detects the sound and outputs a sound. Through the output unit 110, a ring sound indicating that a telephone call is output is output (S301 to S303).

At this time, the caller detector 104 detects caller phone number information on the ring signal, and the control unit 106 checks the caller ID display method set in step S203, and then outputs the OSD output of the caller phone number to the OSD processing unit 108. Outputs a control signal. Thus, the OSD processing unit 108 generates the caller's telephone number information as an OSD signal and outputs it to the OSD screen through the image output unit 109. At this time, the controller 106 sets the caller's telephone number to the preset position and size on the OSD screen. Control to be output (S304 to S306).

After the user who recognizes the ring sound output through the sound output unit 110 checks the caller information through the caller's telephone number OSD screen output through the image output unit 109, the user makes a phone call through the user setting unit 102. If is selected, the control unit 106 checks the sound output limiting method set in step S204 (S307 to S308).

Thus, the controller 106 automatically adjusts the output sound level of the broadcast signal through the sound output unit 110 to a predetermined level or less according to the limiting method set in step S204, or the image output unit 109 and the sound output unit 110. The output function of the broadcast signal through the off (S309).

In addition, the controller 106 stops the output of the ring sound through the sound output unit 110 and performs a call connection function. That is, the sound received from the CO line connected to the phone expansion port 103 is output to the outside through the sound output unit 110, and the sound signal input through the sound input unit 111 is connected to the CO line through the phone expansion port 103. Transmission on the line (S310 to S311).

In this call connection state, when the user inputs a call termination command through the user setting unit 102 or receives a call termination signal from the trunk line connected to the telephone extension port 103, the control unit 106 performs the sound output performed in step S309. After the restriction is released, the process returns to the telephone standby mode as described above (S312 to S313).

In the above description, but limited to one embodiment of the present invention, it is obvious that the technology of the present invention can be easily modified by those skilled in the art. Such modified embodiments should be included in the technical spirit described in the claims of the present invention.

As described above, the present invention is connected to a CO line through a phone extension port to provide a phone call function, and when the caller information is included in a ring signal, the caller's phone number is output to the OSD screen, thereby making it possible to watch a TV while viewing. There is an effect that convenience is provided to perform a phone call without moving.
