Description

201125356 VI. Description of the Invention: [Technical Field] The present invention relates to a display wall multi-image synthesizing system, and more particularly to a display wall multi-image synthesizing system using a clustered processor architecture. [Prior Art] # With the advancement of technology, people are getting more and more channels to receive information. From traditional newspapers and magazines, TVs, mobile phones, to large LCD displays that are everywhere, there is a wealth of information. The large liquid crystal display not only displays a lot of information, but also has a dazzling sound and light effect. Therefore, if you want to get everyone's attention, it is often most effective with large LCDs. However, liquid crystal displays have limitations in manufacturing size, and the manufacturing cost of liquid crystal display increases rapidly with size. Therefore, in the real (four), the type of liquid crystal display if it is tested into an A-size TV wall. In this way, not only can you increase the lung area or put a face, but it can also make the small liquid test a low cost. For example, many airport and station 'researcher stock exchanges use the above-mentioned video wall to provide users with instant information. $ General Office 兮β. 7 by AJ· 1 ...

The TV wall allows the mother's face to be enlarged. The TV wall requires very complicated hardware devices. However, assembling a set of traditional 'general users' is often not possible, and 201125356 can assemble itself. The following is a schematic diagram illustrating the use of the components of the video wall of the prior art. 〃, 再汉/,

Referring to the drawings, the schematic diagram of the video wall of the prior art is shown in Fig. 1. The video wall 9 includes a video splitter 90, a video amplifier 92, a video distributor 94, and a display device array 96. The display device array 96 can be a combination of a plurality of display devices. For example, the display device can be green crystal! Show II, Cathodic Tube (CRT) or projector. After a mother screen is input to the video wall 9, the video plane is first received by the video splitter 90, and the mother picture is divided into a plurality of first-sub-pictures. Then, the plurality of first sub-planes are transmitted to the video amplifier %. Here, the video amplifier 92 is configured to scale up the plurality of first sub-planes into a plurality of second sub-pictures. The plurality of second sub-surfaces are then transmitted by video amplifier 92 to video distributor 94. The wish distributor 94 can determine the position of each of the second sub-surfaces on the display device array 96. That is, the video distributor 94 can individually assign the plurality of first sub-frames to the display device array 96 one by one. Finally, after the video distributor 94 distributes all of the second sub-frames to the display device array 96, the user can see the enlarged mother face from the display device array 96. As can be seen from the above, the main function of the video wall is to enlarge the mother's face and output it by the display device array. However, it is a hardware device that requires precise settings, whether it is a splitter, a video projector or a video distributor. In addition to high cost and difficulty in assembling a video wall, human error is more likely to occur. 201125356 is set to use a combination of small size display device μ: The disadvantage of the method of changing the display content at will. So how do two traditional electronic reading hardware and software devices, shouting large displays (four) 'use flexible use, let =^= face or image appear in large display at the same time", Wuyuan's information change and μ (four) = enter the display window The urination is set to move 'and allows the general user to easily use the video wall, which is the problem to be solved by the present invention.
