4 is an exemplary diagram for describing a performance grade of a terminal for a 3D content of a mobile communication terminal and a method of converting 3D content according to an exemplary embodiment of the present invention.

The terminal information DB 140 stores 3D performance information of the plurality of mobile communication terminals 110, and the 3D performance information includes 3D engine information and 3D performance grade. The information on the 3D performance grade indicates the grade of 3D content that can be executed by the 3D engine provided in the mobile communication terminal 110. The grades are 1st class, 2nd grade, 3rd grade, It may be classified into four grades, but is not limited thereto.

Each grade may be classified into a 3D content processing speed of the mobile communication terminal 110. In FIG. 4, a processing speed of 10 to 30 Kpps (pps: Polygon per Second) is 1 grade, and a processing speed of 50 to 150 Kpps is 2 The grade, 200 ~ 400 Kpps processing speed is 3 grades, the processing speed of 900 Kpps or more is shown as 4 grade, but not limited to this value can be changed.

Typically, the basic format of the 3D content is made of the highest grade, that is, four grades in FIG. 4, and when the 3D performance grade of the mobile communication terminal 110 is lower than four grades, the 3D contents are converted to the corresponding grades.

The conversion engine unit 234 performs conversion operations including polygon and texture conversion, image size conversion, and frame conversion.

Polygon and texture transformation refers to the operation of converting a 3D object having a large number of polygons of 3D content into a 3D object having a small number of polygons to fit the 3D performance class of the mobile communication terminal 110. When operating a 3D object with a large number of polygons in a mobile communication terminal having a low 3D performance class, performance may be degraded. Therefore, a 3D object with a small number of polygons should be converted. Thus, performance is prevented from being degraded through polygon and texture conversion.

In addition, image size conversion refers to an operation of converting a 3D object having a large sized image into a 3D object having a small sized image so as to meet the 3D performance level of the corresponding mobile communication terminal. This is because when a 3D object having a large size image is operated in the mobile communication terminal 110 having a low 3D performance class, such as a polygon, performance may be degraded.

In addition, frame conversion refers to an operation of converting 3D content into 3D content having a number of frames suitable for the 3D performance class of the mobile communication terminal 110. For example, if the mobile communication terminal 110 supports only 10 frames, the mobile communication terminal 110 converts the frame number to the corresponding frame number.

That is, the conversion engine unit 234 of the 3D conversion server 230 receives 4D 3D content and 3D performance level of the mobile communication terminal 110. 4D 3D content is 3000 as shown in FIG. Polygons, an image size of 512 x 512 Pixels, and a frame rate of 20 frames per second (fps).

The conversion engine unit 234 converts the 4D 3D content of the above-described standard to suit the 3D performance grade of the mobile communication terminal 110 that is received together. That is, for example, assuming that the 3D performance grade of the mobile communication terminal 110 is Grade 2, the 3D content of the Grade 2 is 1000 polygons, an image size of 256 * 256 Pixel size, 15 as shown in FIG. It has a frame rate of fps, which converts the number of frames of 4 grade 3D content from 3000 to 1000, converts the image size from 512 * 512 Pixel to 256 * 256 Pixel, and the frame rate of 20 fps. By converting the number of frames from the number of frames to 15 fps, 4 grade 3D contents are converted into 2 grade 3D contents.

In the above, when the 3D engine version is the same and the 3D performance grade of the mobile communication terminal is not the basic grade, that is, the fourth grade in FIG. 4, the frame number, the image size, the polygons, and the textures are appropriate. It was explained about the conversion.

However, different 3D engine versions may occur. In this case, since the API (Application Programming Interface) itself for executing the 3D content is different, it is preferable to change the 3D content to the 3D engine version of the mobile communication terminal 110 and provide the same. In addition, when the 3D engine cannot be executed because the 3D engine is not provided in the mobile communication terminal 110, it is preferable to convert the 3D content into 2D content and provide the 2D content.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, the optimized 3D content can be provided regardless of the performance of the terminal with respect to the 3D content of the mobile communication terminal. Contents can be used, and mobile operators can create more profit by integrating 3D content into various services.
