Like reference numerals refer to like elements throughout.

1 and 2 show a video call screen according to an embodiment of the present invention, Figure 3 shows a template for providing an overlayed video service menu.

1 illustrates a case of using a mobile video contact center of a mobile communication company, and a video call user presses a mobile video contact center representative number (15XX-0000) on a terminal keypad to make a video call connection to a mobile video contact center of a mobile carrier. When the request is made, the initial standby screen 102 is displayed.

The mobile carrier may use the initial standby screen 102 to promote new product terminals, provide information such as corporate image advertising, traffic, weather, securities, news, performances, recordings, movies, or perform push marketing or event guidance. Through this, it is possible to generate revenue such as information usage fee and advertisement fee (case 1; telecommunication company-> user-oriented service).

On the other hand, the lower left and the lower right of the initial standby screen 102 may be provided with an image area consisting of a separate frame, for example, the lower left image is the video call user's own image and the image at the lower right is on behalf of the video call user It may be a substitute image image to be transmitted.

The lower part of FIG. 1 shows a state where the initial standby screen is changed to a menu screen.

At the top of the menu screen, a service guidance image 104 of a contact center for a customer is played, and a contact center service menu 106 that the customer can select is provided (Example 2; User-> Telecommunication Service Direction Service). .

Here, the service guide voice for each service menu 106 may be provided together, and the service menu 106 is implemented as a browsing function like an internet browser, and a key mapping function for each menu is provided to select a menu. , Move, cancel, etc. functions may be provided. When the customer selects one of the service menus 106, the information is converted to the service guide image 104 corresponding to the corresponding service, and the information included in the guide image is provided to the customer in the form of video, voice, text, and the like.

In this service menu 106, it is essential that an agent connection is provided, and when a customer selects an agent connection, the agent's image 108a is displayed in a lower left corner as a separate image frame. In this case, an image of the customer may be displayed on the lower right end, or an alternative image 108b set by the customer or the counselor may be displayed. The alternative video is provided by synchronizing the voice of the customer or the counselor to an image such as an avatar, and the method of providing the alternative video is already known in various ways, and thus description thereof will be omitted.

On the other hand, instead of the service guide image 104, information such as traffic, weather, securities, news, performances, recordings, movies, such as additional services such as surveys, push marketing, event guide, etc. may be provided. It can also generate revenue such as information usage fees and advertising fees.

Meanwhile, as shown in FIG. 2, a third party (eg, a company, an operator, a public institution, etc.) that is not a mobile carrier operates its own mobile video contact center or uses a mobile video contact center of a mobile carrier to provide a video counseling service. If you do, the customer dials the contact number of the contact center and makes a video call, and the service provider provides the customer with a video consultation service, for example, in-house promotion, insurance sales, home shopping, and product introduction. (Example 3; Service Provider-> Carrier-> User Oriented Service).

To this end, the service provider may produce and provide various image contents or multimedia contents synthesized with video and audio using, for example, an image production tool provided by a telecommunication company or a predetermined standardized image production tool.

In this case, the image may be changed to an input screen 110 in which customer information may be input according to a menu selection instead of an agent's image or a substitute image.

On the other hand, if the service provider creates a video by itself and provides a mobile video contact center service, the burden of creating and providing a new video is inevitable whenever the service video is changed or the menu configuration is changed. Since the content is produced in a single image frame, you must not only attach and produce menu images each time you produce video content, but also reconstruct the cost and inconvenience of reproducing all the videos to which the new menu configuration is attached if the menu changes. This was accompanied.

In order to reduce this disadvantage, the present invention proposes a structure in which the guide video 104 and the menu 106 are overlaid as illustrated in FIG. 3.

That is, as shown in FIG. 3, a template 1 for the guide video 104 part and a template 2 for the menu 106 part overlap each other to provide an image service. Therefore, only the template 1 needs to be produced to change the guide video 104, and only the template 2 needs to be produced to change the menu 106. Therefore, when one part of the guide video or the menu is changed, the entire video must be produced again. Discomfort and associated costs can be reduced. By using the video content production tool in this manner, the service provider can produce various contents more conveniently and quickly to update the service contents. To provide one overlayed image by combining template 1 and template 2, after demuxing the media corresponding to templates 1 and 2, each template image is overlaid, and the plurality of overlayed templates Media muxing process is provided to provide an image as one image.

As described above with reference to FIGS. 1 to 3, when the user of using the video contact center service uses the video contact center service while viewing, listening to, and reading the screen of the mobile communication terminal, the convenience of using the contact center is increased, and the customer is customized when using the video consultation. Providing content can induce customer interest. In addition, as a service provider, an advertisement image and phrases may be inserted into a video service background, a menu moving screen, etc. to perform advertisement / promotion, and to enhance the corporate image by providing a differentiated video service. In addition, mobile operators can generate profits through sales of customer center numbers, video call revenues, and information service revenues, and provide video-based new applications to enhance their competitiveness and enable 3G services. do.
