The present invention relates to a device for receiving and displaying audio and video signals transmitted from an IMT-2000 wireless terminal through a wired video communication device installed in a home or office.

The next generation wireless mobile communication service, IMT-2000 wireless communication service is in the stage of commercialization by solving all technical problems. However, the current IMT-2000 wireless communication service is being developed to be limited to the communication service between IMT-2000 wireless terminals. However, homes and offices will require products and methods that allow them to talk to the IMT-2000 terminal while being placed on a desk or table like a regular telephone. In such a product, a monitor for displaying a video signal transmitted from an IMT-2000 wireless terminal is essential.

Accordingly, an object of the present invention is to provide a device capable of receiving IMT-2000 wireless communication service, which is a next generation wireless mobile communication service, with a video communication device placed on a desk or table in a home or office like a normal telephone.

In addition, the video device according to the present invention also serves as a TV reception function.

1 is an external view of a video communication apparatus according to the present invention for receiving and displaying audio and video signals transmitted from an IMT-2000 wireless terminal.

2 is an internal configuration diagram of a main body of a video communication apparatus according to the present invention.

The video communication apparatus according to the present invention for achieving the above object is described with reference to FIGS. 1 and 2 as follows.

That is, a device for receiving and displaying audio and video signals transmitted from an IMT-2000 wireless terminal placed on a desk of a home or office, and is an operating program for processing audio and video signals wirelessly input from an IMT-2000 wireless terminal. In the video communication apparatus comprising a built-in main body, a monitor connected to the main body and the angle adjustable and outputting a video signal input through the IMT-2000 wireless terminal,

The monitor is equipped with a camera for taking a picture of the caller,

The main body includes a power supply unit which receives power from an external power supply unit and transmits the power, a signal receiving unit for receiving audio and video signals wirelessly transmitted from an IMT-2000 wireless terminal, and an audio and video signal received through the signal receiving unit. A signal processor for processing a signal, a display format converter for converting an image signal among the received signals into a display format, a video output device for outputting the display format converted image signal according to a video signal processing method of a monitor; A speaker for outputting a voice signal of the received signal to the outside, a handset for outputting the voice signal of the received signal through a handset, and receiving a voice spoken by the caller from the outside when the caller talks through the handset For the microphone, the user calls the handset again It comprises a hook (On-Hook) switching the switch-on for selecting one of the speaker / microphone.

In this case, in order to enable TV reception through the monitor of the video communication apparatus, resolution correction for increasing and correcting the resolution of the video signal converted into the display format on the main body to a resolution sufficient to receive TV without distortion of the signal It is preferred to further comprise means and a TV reception tuner for receiving a TV signal.

In addition, in order to allow the video communication device to use a general telephone communication through a normal wired telephone line, the main body further includes a communication port connected to a telephone communication terminal installed in each home or office by wire to transmit and receive a voice signal. It is preferable.

In addition, it is desirable for the video communication apparatus according to the present invention to select a mode of various functions. That is, the main body

'TV reception mode' for only watching TV through the monitor, or

'Video priority output mode', which stops TV video output when the phone comes from the IMT-2000 wireless terminal while watching TV through the monitor, and outputs the video signal transmitted from the IMT-2000 wireless terminal to the monitor first, or

When the phone comes from the IMT-2000 wireless terminal while watching TV through the monitor, the monitor is automatically turned on, so that the video signal transmitted from the IMT-2000 wireless terminal is output to the monitor. , or

It is possible to further include a video output switch for allowing the user to select one of the 'video off modes' that prevents the video signal transmitted from the IMT-2000 wireless terminal from being output to the monitor. .

By using the video communication apparatus according to the present invention, there is an advantage that IMT-2000 wireless service can be easily received in IMT-2000 wireless terminal, home and office.

In addition, the video communication apparatus according to the present invention has the advantage of being able to watch TV by switching to the TV mode if necessary in addition to the advantage of receiving the IMT-2000 wireless service.
