Description
本發明係關於一種顯示牆多影像合成系統,並且特別是有關於一種利用叢集式之處理器架構的顯示牆多影像合成系統。 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.
隨著科技的進步,人們接收資訊的管道也越來越多。從傳統的報章雜誌、電視、手機,到隨處可見的大型液晶顯示器(LCD),無不提供著豐富的資訊。而大型液晶顯示器不僅能顯示相當多的資訊,也同時具備著炫目的聲光效果。所以,若想要得到眾人的注意,往往以大型液晶顯示器最為有效。 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.
然而,液晶顯示器有製造尺寸的限制,且液晶顯示器的製作成本隨著尺寸快速增加。因此,於實務中,常用小型的液晶顯示器拼接成大尺寸的電視牆。如此,不僅能有效的增加顯示面積或是放大畫面,同時也能使用較小的液晶顯示器以降低成本。舉例來說,許多機場、車站、研究單位或者證券交易所皆運用上述之電視牆,以提供使用者即時的資訊。 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.
一般來說,傳統的電視牆係將一個母畫面分割成多個子畫面,接著將上述的子畫面放大並組合起來。藉此,傳統的電視牆可使母畫面被放大顯示。然而,組裝一套傳統的電視牆需要非常複雜的硬體設備,一般使用者往往不可 能自己組裝。 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.
以下搭配圖式說明先前技術中之電視牆的架構及其各部元件的用途。 The following diagram illustrates the architecture of the video wall of the prior art and the use of its various components.
請參見圖1,圖一係繪示先前技術中之電視牆的示意圖。如圖一所示,電視牆9包含視訊分割器90、視訊放大器92、視訊分配器94以及顯示裝置陣列96。其中,顯示裝置陣列96可為多個顯示裝置的組合。舉例來說,顯示裝置可為液晶顯示器、陰極射線管(CRT)或者投影機。 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.
當一個母畫面輸入電視牆9之後,首先由視訊分割器90接收母畫面,並將母畫面分割成多個第一子畫面。接著,將所述多個第一子畫面傳送至視訊放大器92。在此,視訊放大器92用以依比例放大所述多個第一子畫面成為多個第二子畫面。接著,所述多個第二子畫面由視訊放大器92傳送至視訊分配器94。而視訊分配器94可決定每一第二子畫面於顯示裝置陣列96的位置。也就是說,視訊分配器94可逐一將所述多個第二子畫面全部對應至顯示裝置陣列96。最後,當視訊分配器94將所有第二子畫面皆分配至顯示裝置陣列96之後,使用者可由顯示裝置陣列96看到被放大後之母畫面。 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.
由上述可知,電視牆的主要功能就是將母畫面放大,並由顯示裝置陣列輸出。但是不論是視訊分割器、視訊放大器或視訊分配器,皆為需要精密設定的硬體設備,除了高成本以及組裝電視牆的困難度高之外,更容易產生人為的操作錯誤。 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.
綜上所述,傳統的電視牆雖利用組合小尺寸的顯示裝置以顯示大尺寸的畫面,但其同時也具有昂貴的硬體設備以及操作不易、無法隨意更動顯示內容的缺點。所以如何簡化傳統的電視牆之軟硬體設備,組成大面積超高解析度的大型顯示空間,進行靈活運用,讓多方訊號源的資訊畫面或影像同時出現在大型顯示空間,進行顯示視窗大小便更及位置更動,並讓一般使用者能夠輕易組裝電視牆以及使用電視牆,係本發明欲解決的問題。 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.

最後,再由顯示裝置52、顯示裝置54、顯示裝置56以及顯示裝置58依據個別接收的第三視訊,分別顯示一顯示畫面。另外,顯示裝置52、顯示裝置54、顯示裝置56以及顯示裝置58其中任一顯示裝置可同步顯示顯示裝置50之畫面。於實務中,顯示裝置52、顯示裝置54、顯示裝置56以及顯示裝置58不限定只能組成二維陣列,上述之顯示裝置更可以設置於不同平面上。舉例來說,上述之顯示裝置可根據不同視覺效果的需要,分別設置於牆壁與天花板。 Finally, the display device 52, the display device 54, the display device 56, and the display device 58 respectively display a display screen according to the individually received third video. In addition, any of the display device 52, the display device 54, the display device 56, and the display device 58 can simultaneously display the screen of the display device 50. In practice, the display device 52, the display device 54, the display device 56, and the display device 58 are not limited to form a two-dimensional array, and the display device may be disposed on different planes. For example, the above display device can be respectively disposed on the wall and the ceiling according to the needs of different visual effects.
由上述具體實施例之中,顯示牆多影像合成系統4採用叢集式的電腦架構,可實現放大主控端的電腦畫面於陣列式的多個顯示裝置。 In the above specific embodiment, the display wall multi-image synthesizing system 4 adopts a cluster-type computer architecture, and can realize amplifying the computer screen of the main control end in an array of a plurality of display devices.
綜上所述,藉由主控端與從屬端的處理器架構進行視 訊處理,於第一處理器以及第二處理器之間使用網路耦接,並且第一處理器以及第二處理器可分階段處理所接收的視訊。因此,有別於傳統的電視牆,本發明之顯示牆多影像合成系統不需要外接複雜的硬體設備,可使用分散式或者叢集式的架構,由多個從屬端的處理器對應連接顯示裝置,放大主控端的處理器畫面於陣列式的多個顯示裝置。 In summary, through the processor architecture of the master and slave The processing is performed by using a network coupling between the first processor and the second processor, and the first processor and the second processor can process the received video in stages. Therefore, unlike the conventional video wall, the display wall multi-image synthesizing system of the present invention does not require external complicated hardware devices, and may use a distributed or clustered architecture, and the processors of the plurality of slaves are correspondingly connected to the display device. The processor screen of the main control terminal is enlarged in a plurality of display devices of the array type.
藉由以上較佳具體實施例之詳述,係希望能更加清楚描述本發明之特徵與精神,而並非以上述所揭露的較佳具體實施例來對本發明之範疇加以限制。相反地,其目的是希望能涵蓋各種改變及具相等性的安排於本發明所欲申請之專利範圍的範疇內。因此,本發明所申請之專利範圍的範疇應該根據上述的說明作最寬廣的解釋,以致使其涵蓋所有可能的改變以及具相等性的安排。 The features and spirit of the present invention will be more apparent from the detailed description of the preferred embodiments. On the contrary, the intention is to cover various modifications and equivalents within the scope of the invention as claimed.
