TV receiver for providing the visitor information according to the present invention for achieving the above object, the door phone for transmitting the voice signal and video signal of the visitor, when the visit bell is input, and is connected to the door phone so as to interface with the door phone And a TV set for receiving and storing a visitor's audio signal and a video signal and for outputting visitor information when the user requests.

A method of implementing a TV receiver for notifying visitor information according to the present invention includes a first step of connecting a door phone and a TV set, a second step of setting the TV set to the visitor information storage mode, and a visitor transmitted from the door phone. In the third step of storing the audio signal and the video signal of the; and the fourth step of outputting the video of all the visitors stored in the third step if the visitor confirmation key is input, and in the fourth step, the visitor selection key is selected, And a fifth step of outputting only the voice and video of the visitor.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a TV receiver for informing visitor information according to an embodiment of the present invention. 1 shows a door phone 10 installed outside of a general home and a TV set 20 installed inside. The door phone 10 includes a control unit 11 for controlling each component, an interface 12 for interfacing with the TV set 20, a visit bell input unit 13 for receiving a visit bell signal of a visitor, and a door phone. (10) a voice signal input unit 14 for receiving a visitor's voice from an external speakerphone (not shown), and a video signal for receiving a visitor's image from a camera (not shown) installed outside the door phone 10. The input unit 15 is included. The TV set 20 has a control unit 21 for controlling each component therein, an interface 22 for interfacing with the door phone 10, a storage unit 23, and signal processing for outputting audio signals. An audio signal processor 24 and a video signal processor 25 for signal processing to output an image signal. The TV set 20 also includes a key input unit 26, a speaker 27, and a monitor 28 externally.

The apparatus of FIG. 1 configured as described above will be described in more detail with reference to FIGS. 2 and 3.

FIG. 2 is a flowchart for describing a method of notifying visitor information implemented by the apparatus of FIG. 1.

In Fig. 1, the user sets the visitor information storage mode in the absence via the key input section 26 of the TV set 20 (step 201). Then, the control unit 21 enters a standby state for executing the visitor information storage mode. That is, when the visitor presses the door bell (not shown) of the door phone 10, the door bell input unit 13 receives the door bell input signal and outputs the door bell input signal to the controller 11. Then, the controller 11 allows the camera (not shown) and the speakerphone (not shown) to operate by switching. The video signal input unit 15 receives a video signal of a visitor input from a camera (not shown), and the audio signal input unit 14 receives a voice signal of a visitor input from a speaker phone (not shown). The controller 11 transmits the visitor information such as the audio signal and the video signal of the visitor, which are input to the audio signal input unit 14 and the video signal input unit 15, to the TV set 20 through the interface 12. Then, the interface 22 of the TV set 20 receives it and outputs it to the controller 21. The controller 21 outputs the input visitor audio signal and the video signal to the audio signal processor 24 and the video signal processor 25, respectively. The audio signal processing unit 24 processes the signal to output the visitor's audio signal input from the control unit 21, and the video signal processing unit 25 processes the signal to output the visitor's video signal input from the control unit 21. do. The control unit 21 stores the audio signal and the video signal signal-processed to be output in the storage unit 23 (step 202). When a visitor is input even when several visitors visit, the storage unit 23 of the TV set 20 stores visitor information, which is audio and video signals of all visitors, through the above-described process. In this way, if the user wants to check the information on all the visitors who visited the stored absence, the user inputs the visitor confirmation key through the key input unit 26 provided outside the TV set 20. Then, the controller 21 determines whether the visitor confirmation key is input (step 203). As a result of the determination, when the visitor identification key is input, the controller 21 reads out all the visitor information stored in the storage unit 23 and controls the image of the visitor to be output through the monitor 28 as a multi-PIP screen (step) 204). The user can see all the visitors who visited in the absence as shown in FIG. 3 via the monitor 28. Then, if the user wants to hear a voice message of a specific visitor, the user selects one of the multi-PIP screened visitors through the key input unit 26. Then, the controller 21 determines whether the visitor selection key has been input (step 205). As a result of the determination, when the visitor selection key is input, the controller 21 outputs the image of the selected visitor to the entire screen of the monitor 28, and simultaneously outputs only the voice message of the selected visitor through the speaker 27 (step). 206). Therefore, the user can check all the visitors who visited the absence, can see the specific visitor in more detail, and can check the voice message.

The present invention can easily identify the visitor's identity and the purpose of visit that the user visited in the absence, which is effective for security functions.
