How to convert wallpaper for videophone terminal {Method for conversion background of video phone}

The present invention relates to a method for converting a background screen of a video telephone terminal. More particularly, the present invention relates to a method of converting a background image of a video telephone terminal, which is capable of making a video call with a counterpart without exposing his / her current position by converting a call background image into a desired moving image and a still image during a video telephone call.

In the early 1980s, in North America, the service area was divided into hexagonal cells of several Km to several 10Km in diameter, and the same frequency channel was repeatedly used in geographically separated cells, and wireless channel switching between cells was implemented as subscribers moved. The first commercialization of a cellular mobile communication system has enabled mobile phones to become a universal service.

In addition, in recent years, a variety of wireless communication systems have been commercialized, such as the explosive increase in the demand for mobile terminals, and is preparing a new heyday of wireless communication.

Mobile communication can be viewed as a form of adding mobility to an existing communication service. A type of mobility includes terminal mobility in which a terminal can be freely moved by being released from a subscriber line, and a user moves to an arbitrary terminal. There are user mobility that can communicate, and service mobility that can accommodate not only voice but also data and video by widening the wireless channel by increasing the use frequency band.

With the development of technology, the miniaturization and weight reduction of the mobile terminal is rapidly spreading to the personal portable mobile terminal.

In such personal portable devices, if the mailbox subscriber cannot receive a call on the mobile device, the voice mail allows the caller to leave the message in the mailbox subscriber's voice mailbox or fax mailbox so that the mailbox subscriber can check the message. Voice Mail Service (also known as voice mail service) connects voice recognition equipment to mobile phone system to memorize / register subscriber's voice so that subscriber can make a voice call without dialing a phone number when making mobile phone call. Voice Activated Dialing Service, which can receive numeric and text messages (about 40 characters in English, 80 characters in English) or various life information as texts through the screen of the mobile terminal, and when the subscriber uses the voice mail service Notify by mobile phone upon arrival when a message arrives Gives gives provide such a mobile telephone short message service (Short Message Service) to be also used as a paging service.

Accordingly, in the mobile communication network as described above, as well as providing a general voice call service, a data file such as a large amount of video or text can be transmitted at high speed using a data packet method, thereby providing a high quality communication service. In addition, it is expected to be able to provide various additional services.

Further, a third generation mobile communication system called IMT (International Mobile Telecommunications) -2000 has been in the spotlight, and this third generation mobile communication system has been developed according to the needs of mobile users such as PSTN / ISDN / B-ISDN. A mobile communication system for accessing various communication services supported by a fixed communication network using a wireless link.

The frequency bands used are 1,885 MHz to 2,025 MHz and 2,110 MHz to 2,200 MHz, as determined in WARC (now replaced by WRC) -92, which not only provide existing communication services but also provide a higher level of service through advanced technology. In the next generation mobile communication system, various types of mobile terminals that can be connected to a terrestrial or satellite network are used for mobile communication or fixed communication.

IMT-2000 is able to interoperate with various systems, has high service compatibility by worldwide operation, and has the features of using small size and light weight terminal with high quality.

IMT-2000 is a mobile communication system that provides not only voice and data but also multimedia services such as high-speed data and video communication up to 2Mbps. It adopts the concept of layer cell (pico, micro, macro cell, etc.) I aim to roam.

In addition, IMT-2000 uses a total of 230 MHz in the common frequency band (1,885 MHz to 2,025 MHz, 2,110 MHz to 2,200 MHz) worldwide, and the satellite portion of the IMT-2000 is limited to the bands 1,980 to 2,010 MHz and 2,170 to 2,200 MHz. As a result, international roaming is possible because it uses a common wireless standard.

In this way, IMT-2000 integrates existing terrestrial mobile communication and satellite mobile communication systems, allowing mobile terminals to move freely, personal mobility for subscribers to receive services from any terminal, voice and video during the move. It aims to satisfy service mobility that can use various services.

On the other hand, when a third-generation mobile communication system such as IMT-2000 is popularized and a telephone call is made with a wireless mobile terminal capable of video call, the call is viewed while viewing each other's face and surrounding screen through the display panel. Done.

At this time, even though one caller does not want to show his / her current place to the other party, the surrounding screen (background screen) is exposed to the other party as it is and is in a difficult situation. Also, monotonous or inappropriate backgrounds can adversely affect the mood of a video call.

Therefore, the present invention is to solve the above problems, the present invention converts the call background to the desired moving picture and still image when the video phone call with the other party to remind the possibility of leakage of personal information and video call atmosphere Its purpose is to.

1, a video telephone terminal 10 capable of connecting to a communication network 20 to make a video call with a called party and transmitting and receiving various information between the caller and the called party; A wallpaper DB 40 for storing wallpaper information for each subscriber for each situation; And information on a background screen during a video call selected by each subscriber, and as a telephone call request is received from any one subscriber through the communication network 20, a background image selected by the subscriber and a video of the subscriber are synthesized. Thereafter, the background screen synthesis server 30 is transmitted to the subscriber terminal capable of making a video call through the communication network 20.

Here, the video telephone terminal 10 includes an IMT-2000 and all terminals capable of video calls, and can be connected to other communication networks through the communication network 20, and through the communication network 20 and other communication networks. Audio, video and multimedia can also be transmitted and received.

The communication network 20 may be a wired or wireless network, that is, an internet network using a TCP / IP protocol that can be connected by wire and a WAP protocol that can be connected by wireless, such as a public line network (PSDN) or a public telephone network (PSTN). It may be configured as.

The contextual wallpaper information stored in the wallpaper DB 40 is produced in the form of a video or a still image, and is set based on a user's surroundings, for example, an office interior screen, an exterior or interior of a house where the user resides. Various information such as a screen is included.

In addition, it is possible to change the wallpaper according to the user's setting. Such contextual background information consists of a plurality of various contextual backgrounds input by each user for each subscriber.

The background composition server 30 stores personal information (eg, name, age, address, etc.) and terminal information (eg, terminal phone number (MIN), terminal unique number (ESN), etc.) of each subscriber. .

The background composition server 30 grasps the background image selected by the subscriber among the various situational background images, and when the telephone is subsequently called, the selected background image is the video telephone terminal 10 of the subscriber. Display as a background screen on a display panel (not shown). At this time, a function of removing the user's own image itself and simply transferring the designated background screen, that is, the replacement screen, to the counterpart is included.

Meanwhile, in the embodiment of the present invention, the operation of synthesizing the video of the caller with the above-described background screen is performed by the background screen synthesis server 30, but may be performed by the wireless mobile terminal.

That is, when the wireless mobile terminal performs an operation of synthesizing the video of the caller with the background screen, the user selects the background image selected by the user with a plurality of background images pre-inputted by the user in the wireless mobile terminal. The video is synthesized in the wireless mobile terminal and then transmitted to the other party's wireless mobile terminal.

2 is a flowchart illustrating a process of converting a background screen of a video telephone terminal according to an exemplary embodiment of the present invention.

First, the user of the video phone terminal 10 is connected to the communication network 20 and then connected to the background composition server 30 linked to the communication network 20, and the background wallpaper is set in advance during the video call Sign up to receive additional services that can be converted (S100).
