Television with video calling function {TELEVISION HAVING A DISPLAY PHONE FUNCTION}

The present invention relates to a television having a video telephony function. More particularly, the present invention relates to a main screen and a sub-screen displayed on a display when a broadcast viewing and a video telephony are simultaneously performed. The present invention relates to a television having a video telephony function capable of transmitting and receiving a video call even from a distance away from the television.

A television typically receives a broadcast signal transmitted from a broadcasting station, outputs a video signal through a screen, and outputs an audio signal through a speaker. As an analog broadcast is recently converted into digital broadcast, digital television takes up most of the time.

As digital television is becoming more popular due to the transition to digital broadcasting, viewers are able to select channels while receiving dozens and hundreds of broadcasts through terrestrial, satellite, cable and IP (Internet) broadcasting. In addition, recently, thanks to the development of network infrastructure and Internet informatization, it has become a reality to make a telephone call or a video call simultaneously while watching a broadcast on a television by adding a telephone call function and a video call function to a television.

When a video call is attempted while watching a broadcast, the video call screen is displayed as a small sub-screen on one side of the broadcast screen, so that the user clearly sees the video call screen. In order to make a call, there is a problem that the TV screen must be close.

In addition, when making a video call at a location far from the television screen, the audio output must be increased so that the other party's voice can be heard accurately, which causes noise pollution.

The present invention has been made to improve the above-described problems, the present invention, the main screen and the sub-screen displayed on the display when the broadcast viewing and video call at the same time, as well as the external input device It is an object of the present invention to provide a television having a video telephone function capable of easily making a video call from a distance away from a television screen by allowing the user to transmit and receive a voice required for a video call.

Another object of the present invention is to provide a television having a video telephone function capable of displaying text messages on a display portion during a video call.

According to an aspect of the present invention, a television having a video telephone function includes a broadcast signal input unit for receiving a TV signal, a video signal transmitter / receiver for transmitting and receiving a video signal for a video call, the broadcast signal input unit and the video signal transmission. A signal processor for receiving a broadcast signal and a video signal from a receiver and processing the same as a video signal and a voice signal, and a video signal received from the signal processor and provided to a display unit in the form of a broadcast video screen and a video screen. And a controller for controlling the video signal processor to adjust the size of the broadcast video screen and the video screen displayed on the display unit.

The video signal processor may further include a PIP generating unit for switching the broadcast signal and the video signal output from the signal processor into a main screen and a sub-screen.

The apparatus may further include a text message receiver configured to receive a text message received through the Internet access unit and to display the text message on the display unit.

The apparatus may further include an external input device generating a signal so that the broadcast video screen and the video screen are displayed on the display unit.

The external input device may further include a transmitter / receiver configured to input and output a voice of a user.

According to the television having a video call function according to the present invention as described above, it is possible to switch between the main screen and the sub-screen displayed on the display unit for the user's convenience when the video call is made at the same time as the broadcast viewing, Since the voice required for the video call is transmitted and received through an external input device, there is an effect that can easily make a video call even from a far away from the TV screen.

In addition, the present invention, there is an effect that the text message is displayed through the display unit during the video call.

Specific embodiments of the present invention will be described with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, the definitions of these terms should be made based on the contents throughout the specification.

Hereinafter, a television having a videophone function according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram schematically showing a system to which a television having a videophone function is applied according to an embodiment of the present invention, and FIG. 2 is a configuration of a television having a videophone function according to an embodiment of the present invention. A block diagram is shown.

1, the television 100 according to the present invention is connected to the Internet network 300 to enable video calls and broadcast reception, and is operated and controlled by a remote controller 200 which is an external input device. . In addition, the television 100 further includes a video camera 101 to transmit and receive a user's video and audio, and the video call screen 10 generated during the video call is displayed on the display 110 where a broadcast video screen is provided. Is provided. At this time, the video call screen 10 is displayed along with the appearance of the counterpart and the user during the video call. In addition, the remote controller 200 is further provided with a handset function so that when the video call is implemented through the television 100, the voice 100 can be easily delivered even at a far distance from the television 100.

In the present embodiment, video communication using the Internet network 300 is described as an example. However, a mobile communication network, a telephone network, or the like may be used if video and audio can be received and received.

2, the television 100 according to the present invention, a broadcast signal input unit 120 for receiving a broadcast signal through the Internet network 300, and receives and transmits a video call signal through the Internet network (300) A video signal transmitter / receiver 130, a broadcast signal inputter 120 and an internet connection unit 140 connecting the video signal transmitter / receiver 130 with the Internet network 300, a broadcast signal inputter 120 and A signal processor 150 for processing signals transmitted and received through the video signal transmitter / receiver 130 and a video signal processor for receiving a video signal from the signal processor 150 and providing a broadcast video screen and a video screen to a display unit. And a memory unit 170 and a controller 180 capable of storing video call contents.

The signal processor 150 receives the broadcast signal and the video signal from the broadcast signal input unit 120 and the video signal transmitter / receiver 130, respectively, and decodes them into respective video and audio signals.

The video signal processor 160 provides each video signal input from the signal processor 150 to the display 110 in the form of a broadcast video screen or a video screen. Specifically, when only the broadcast video signal is input to the video signal processor 160, the display 110 provides only the broadcast video screen for viewing the broadcast. When only the video signal is input, the display 110 broadcasts the video for the video call. Only the screen is provided. In addition, when both the broadcast video signal and the video signal are input to the video signal processor 160, the display 110 is provided with the broadcast video screen and the broadcast video screen at the same time.

 That is, the video signal processor 160 simultaneously provides the broadcast video screen or the video screen to the display 110 or provides the broadcast video screen and the video screen, respectively.
