1 is a block diagram of an apparatus for an embodiment of the present invention, as shown in FIG. 1, an image processor 120 for processing a video signal input from a camera 110 or a video signal transmitted and received by an RF circuit 160. LCD (130) for displaying the video signal processed by the image processing unit 120 as an image on the screen, a message processing unit 170 for decoding the received text message and encoding a text message to be transmitted, and a video call The video processor 120 processes the video signal output from the image processor 120 and outputs it through the RF circuit 160, and separates the digital video signal from the signal received by the RF circuit 160 to the image processor 120. In the case of text message processing, the text message input from the key input unit 140 is transmitted to the message processing unit 170, and then the encoded message is output to the RF circuit 110. A text message is configured to include a controller 150 for displaying the message on the LCD 130, and outputs to the image processor 120, a message decoding and then passed to the message processor 170, either automatically or manually.

In the drawing, reference numeral 180 denotes a memory, which temporarily stores a video signal and a text message transmitted from the controller 150.

Referring to Figures 2 and 3 the operation and effect of the embodiment of the present invention configured as described above are as follows.

Short service of the present invention can be divided into a method using a video call channel and a method using a short message service (SMS) server.

2 is a signal flowchart illustrating a short message transmission / reception process when an SMS server is used in an embodiment of the present invention.

3 illustrates a method for displaying a short message during a video call according to an embodiment of the present invention.

First, a method of providing a short message service using a video call channel will be described.

If the user sets the message mode using the key input unit 140 when the video call is transmitted by transmitting an image (eg, a user image) captured by the camera 110 to the opposite camera phone through the RF circuit 160, the controller ( 150 controls the image processor 120 to switch the video call screen displayed on the LCD 130 to a background screen and to display a message input screen on the background screen.

Thereafter, when a user inputs a message, the controller 150 stores the same in the memory 180 and displays the same on a background screen displayed on the LCD 130 through the image processor 120.

Thereafter, when the message is input and the user presses the transmission key, the controller 150 transmits the message stored in the memory 180 to the message processing unit 170, encodes the message, and transmits the encoded message to the video call channel. Convert to

Here, the form that can be transmitted through the video call channel may be an example of processing a text message based on the protocol of the international video standard (H.324 / H.320).

Accordingly, the controller 150 outputs the converted message to the RF circuit 160 and transmits the converted message to the opposite camera phone through the video call channel.

When the text message transmitted from the opposite camera phone is received by the RF circuit 160, the controller 150 extracts the corresponding message, temporarily stores the message in the memory 180, and transmits the message to the message processor 170.

Thereafter, the controller 150 stores the text message decoded by the message processor 170 in the memory 180 and then controls the image processor 120 to switch the video call screen displayed on the LCD 130 to the background screen. Let's do it.

Accordingly, the controller 150 outputs the text message stored in the memory 180 to the image processor 120 to display the corresponding text on the background screen displayed on the LCD 130.

Here, the text message display method is displayed on the background screen to which the video call screen is switched, as shown in the example of FIG.

In the above process, since a message is transmitted and received using a video call channel, there is no need to access a separate SMS server.

Also, in the present invention, a text message may be transmitted using a separate SMS server during a video call. This process is described in FIG. 2 as follows.

When a video call channel is connected between the camera phone 210 and the camera phone 230 and the video call is in progress, the user of the camera phone 210 sets a mode for sending a text message to input and send a text message. When the key is pressed, the camera phone 210 transmits the corresponding text message to the SMS server 220.

Here, the camera phone 210 connects the communication channel with the SMS server 220 at the time when the text message mode is set or when the user presses a key for text message transmission.

At this time, the SMS server 220 responds to the message acknowledgment to the camera phone (210).

Thereafter, the SMS server 220 analyzes the text message and checks the phone (here, the camera phone 230) to which the text message is to be received, and then connects the communication channel with the camera phone 230.

Accordingly, when the SMS server 220 transmits the corresponding text message to the camera phone 230, the camera phone 230 performs the above-described message processing and switches the video call screen to the background screen and then the background. The text message is displayed on the screen as shown in the example of FIG.

That is, the present invention is to display a text message on the screen after switching the video call screen to the background screen without switching to the text message screen when sending and receiving a text message (for example, SMS) between the user during the video call .

As described in detail above, when the text message mode is set during a video call, the present invention converts the video call screen to a background screen and displays a text message on the background screen, thereby making it unnecessary for the user to switch to the text message screen. Has the effect of providing.
