Description

Wireless phone set with TV remote control {Wireless handset adding TV remute control}

The present invention relates to a wireless telephone to which a TV remote control for a video call is added. More specifically, the wireless telephone is equipped with a TV remote control function and a function button (video call, video stop, display, etc.) used in the video phone, so that the TV can be used instead of the LCD of the video phone during the video call. It relates to a technology that allows control.

Conventional remote cordless telephones can control televisions without the need of a separate remote control by adding a remote control function to an auxiliary device separated from the main body of the radiotelephone. Could do it.

As a related art, a utility model called "Application No .: 20-1995-049976, Designated name: Remote control combined use wireless telephone" has been disclosed.

The wireless remote telephone combined with the remote control incorporates a television adjustment mode into the wireless telephone so that the television can be controlled using a special character and a shortcut key of the wireless telephone, and a television subscriber can process the received signal in conjunction with the television adjustment mode of the wireless telephone. It is possible to provide more convenience to users of general wireless telephones by incorporating a wireless telephone reception signal processing unit in the indoor device so that the television channel can be changed by a general wireless telephone.

In addition, as a related art in the related art, a utility model called "Application No .: 20-1996-028553, Name of the invention: Wireless telephone with a remote control" was disclosed.

The remote control combined wireless telephone includes a memory unit configured to store a remote controller operation signal for at least two electronic products; A key input unit of a selection code for selecting one of the electronic products; An infrared light emitting unit for transmitting the operation signal; And a control unit controlling the memory unit, the key input unit, and the infrared light emitting unit.

It can control a variety of models with just one remote control cordless phone. Therefore, a separate remote control is unnecessary, and there is no need to match the manufacturer of the television and the manufacturer of the radiotelephone, thus providing a wide range of purchase options for consumers, and the user can provide convenience by simply inputting a selection code. .

However, the above-mentioned conventional techniques are not intended to control a television to use a video telephone but to seek convenience by simply controlling the television from a wireless telephone without using a remote controller separately.

In addition, the conventional remote-controlled cordless telephone has a simple function because it does not have information about a button and a video telephone required for a video telephone in a set-top box or other type of telephone having a video telephone function. . Of course, you can express the function by pressing several buttons in sequence, but this is inconvenient in use.

Accordingly, the present invention is to solve the above problems, the present invention by adding a remote control function and a function button (video call, video stop, display, etc.) used in the video telephone to the wireless telephone, the liquid crystal of the video telephone during the video call In order to control the TV in place of the display (LCD), the purpose of the video phone is applied to the TV to avoid inconvenience.

As a technical idea for achieving the above object of the present invention

Photographing means for photographing an image of the caller; A TV receiver for displaying an image photographed from the photographing means; A set-top box for interfacing with the TV receiver and allowing video calls; The set-top box is connected to the wireless communication, the TV receiver and the remote control for a video phone, characterized in that it comprises a wireless phone with a remote control mode key for remote control by infrared data communication (IrDA). An additional cordless phone is provided.

1 is a schematic configuration diagram of a wireless telephone to which a TV remote control for a video telephone according to the present invention is added.

FIG. 2 is a detailed block diagram of the set top box and the wireless telephone shown in FIG. 1.

3 is a flowchart illustrating a video call process of a wireless telephone according to the present invention.
