Display wall multi-image synthesis system

The present invention relates to a display wall multi-image synthesizing system, and more particularly to a display wall multi-image synthesizing system utilizing a clustered processor architecture.

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 liquid crystal displays (LCDs) everywhere, there is a wealth of information. Large LCD monitors not only display a lot of information, but also have dazzling sound and light effects. Therefore, if you want to get everyone's attention, it is often most effective with large LCD monitors.

However, liquid crystal displays have limitations in manufacturing size, and the manufacturing cost of liquid crystal displays increases rapidly with size. Therefore, in practice, small-sized liquid crystal displays are often spliced into large-sized video walls. In this way, not only can the display area be enlarged or the picture can be enlarged, but also a smaller liquid crystal display can be used to reduce the cost. For example, many airports, stations, research units or stock exchanges use the above-mentioned video wall to provide users with instant information.

In general, a conventional video wall system divides a mother picture into a plurality of sub-pictures, and then enlarges and combines the above-described sub-pictures. Thereby, the conventional video wall can make the mother picture enlarged. However, assembling a traditional TV wall requires very complicated hardware equipment, which is often not available to the average user. Can assemble by yourself.

The following diagram illustrates the architecture of the video wall of the prior art and the use of its various components.

Please refer to FIG. 1. FIG. 1 is a schematic diagram showing a video wall in the prior art. As 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 a liquid crystal display, a cathode ray tube (CRT), or a projector.

After a mother picture is input to the video wall 9, the mother picture 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-pictures are transmitted to the video amplifier 92. Here, the video amplifier 92 is configured to scale up the plurality of first sub-pictures into a plurality of second sub-pictures. Then, the plurality of second sub-pictures are transmitted by the video amplifier 92 to the video distributor 94. The video distributor 94 can determine the position of each of the second sub-pictures on the display device array 96. That is, the video distributor 94 can all correspond to the plurality of second sub-pictures to the display device array 96 one by one. Finally, after the video distributor 94 distributes all of the second sub-pictures to the display device array 96, the user can see the enlarged mother picture 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 picture and output it by the display device array. However, whether it is a video splitter, a video amplifier or a video splitter, it is a hardware device that requires precise setting. In addition to high cost and difficulty in assembling a video wall, human error is more likely to occur.

In summary, the conventional video wall utilizes a combination of a small-sized display device to display a large-sized screen, but at the same time, it has an expensive hardware device and has the disadvantage that it is difficult to operate and cannot display content at will. So how to simplify the traditional video wall hardware and software devices, to form a large-area super-high resolution large display space, flexible use, so that the information screen or image of the multi-source signal appears in the large display space at the same time, display window size Moreover, the position is changed, and the general user can easily assemble the video wall and use the video wall, which is the problem to be solved by the present invention.
