分布式矩陣、信號分配器、信號延長器、處理器等設備都是液晶拼接墻顯示系統中的常見的信號處理設備，其中分布式矩陣的應用范圍較為廣泛：包括了監控中心、指揮調度中心、城市建設(she)、國(guo)防、新(xin)能源(yuan)等眾(zhong)多領(ling)域中。

在這些液晶拼接大屏(ping)幕(mu)顯(xian)示(shi)系統(tong)通過分布(bu)式(shi)架構部署、可(ke)以輕(qing)松地實(shi)(shi)現超高(gao)清采(cai)集、無(wu)壓縮(suo)傳(chuan)輸、高(gao)還原清晰顯(xian)示(shi)各個系統(tong)的信(xin)息(xi)，從(cong)而達到在全面實(shi)(shi)時(shi)觀看和掌握各方(fang)面信(xin)息(xi)的同時(shi)還在提高(gao)指(zhi)揮調度和決策的效率和準(zhun)確性、信(xin)息(xi)資(zi)源(yuan)發布(bu)的便(bian)捷(jie)性、故障預警的及(ji)時(shi)性。

一、什么是分布式矩陣，分布式矩陣如何構建液晶拼接墻顯示系統

傳(chuan)統(tong)(tong)(tong)(tong)(tong)矩(ju)陣在應對(dui)多(duo)個(ge)站(zhan)點(dian)(dian)(dian)(dian)的(de)(de)(de)時(shi)候只(zhi)能是(shi)每個(ge)站(zhan)點(dian)(dian)(dian)(dian)安(an)放一(yi)(yi)個(ge)矩(ju)陣、在需(xu)要統(tong)(tong)(tong)(tong)(tong)一(yi)(yi)調度時(shi)每一(yi)(yi)個(ge)站(zhan)點(dian)(dian)(dian)(dian)都要安(an)排(pai)人(ren)進(jin)行手動的(de)(de)(de)矩(ju)陣切(qie)換(huan)，而分布(bu)(bu)(bu)式矩(ju)陣則是(shi)將所(suo)有的(de)(de)(de)站(zhan)點(dian)(dian)(dian)(dian)變(bian)成(cheng)一(yi)(yi)個(ge)整體矩(ju)陣、可(ke)以在中心站(zhan)點(dian)(dian)(dian)(dian)切(qie)換(huan)所(suo)有站(zhan)點(dian)(dian)(dian)(dian)的(de)(de)(de)視(shi)頻和節目源或實(shi)(shi)現各點(dian)(dian)(dian)(dian)的(de)(de)(de)實(shi)(shi)時(shi)控(kong)(kong)(kong)(kong)制(zhi)、授權控(kong)(kong)(kong)(kong)制(zhi)、定(ding)時(shi)切(qie)換(huan)、預(yu)案式切(qie)換(huan)、使眾多(duo)站(zhan)點(dian)(dian)(dian)(dian)真正成(cheng)為(wei)(wei)(wei)(wei)智能站(zhan)點(dian)(dian)(dian)(dian)。其以系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)工(gong)程、信(xin)(xin)息科(ke)學、自(zi)動控(kong)(kong)(kong)(kong)制(zhi)理論等為(wei)(wei)(wei)(wei)指(zhi)導、以行業客戶需(xu)求為(wei)(wei)(wei)(wei)背景將先(xian)進(jin)可(ke)靠的(de)(de)(de)信(xin)(xin)號(hao)采集(ji)與傳(chuan)輸技(ji)術(shu)、音視(shi)頻編解碼技(ji)術(shu)、圖(tu)形(xing)信(xin)(xin)號(hao)轉換(huan)技(ji)術(shu)、多(duo)屏圖(tu)像(xiang)處理技(ji)術(shu)、網絡通(tong)信(xin)(xin)技(ji)術(shu)、智能控(kong)(kong)(kong)(kong)制(zhi)技(ji)術(shu)等融合為(wei)(wei)(wei)(wei)一(yi)(yi)體，為(wei)(wei)(wei)(wei)用(yong)戶提供一(yi)(yi)個(ge)具有高物(wu)理分辨率、高清晰度、高智能化控(kong)(kong)(kong)(kong)制(zhi)、高穩定(ding)性的(de)(de)(de)大流量(liang)圖(tu)形(xing)信(xin)(xin)息處理終端：液晶拼(pin)接(jie)墻(qiang)分布(bu)(bu)(bu)式視(shi)頻矩(ju)陣系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)能夠很好地與用(yong)戶監控(kong)(kong)(kong)(kong)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、指(zhi)揮調度系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、網絡信(xin)(xin)息系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、信(xin)(xin)息發布(bu)(bu)(bu)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、視(shi)頻會議系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、工(gong)業生產控(kong)(kong)(kong)(kong)制(zhi)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、報(bao)警系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、會議錄播(bo)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)、中控(kong)(kong)(kong)(kong)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)(tong)(tong)等連結(jie)集(ji)成(cheng)，并且(qie)可(ke)對(dui)不同類型的(de)(de)(de)信(xin)(xin)號(hao)實(shi)(shi)現兼容(rong)采集(ji)從而形(xing)成(cheng)一(yi)(yi)套功(gong)能完善(shan)、技(ji)術(shu)先(xian)進(jin)、操(cao)作方便的(de)(de)(de)交互式圖(tu)形(xing)信(xin)(xin)息處理及(ji)管理平臺。

二、分布式矩陣優勢解析

1、網絡化(hua)、數(shu)字化(hua)：液晶拼(pin)接大屏幕分(fen)布式矩陣(zhen)采用(yong)(yong)業界最先進(jin)的分(fen)布式處理架構、將(jiang)各種(zhong)類型(xing)的音視頻信號進(jin)行(xing)獨立的網絡化(hua)、數(shu)字化(hua)編碼、傳輸并進(jin)行(xing)解碼顯示：從根本上解決了傳統方案的信號噪聲干(gan)擾(rao)、遠(yuan)距離傳輸衰(shuai)減、信號質量下降等(deng)技術難點，并且采用(yong)(yong)分(fen)布式、節點化(hua)的軟硬件設計使得系(xi)統性能和穩定性都大幅提高(gao)。

2、超(chao)強(qiang)信號(hao)顯示(shi)能力：可實(shi)現所有信號(hao)源的接入(ru)管理、上屏顯示(shi)，在液晶拼接墻(qiang)顯示(shi)屏幕上可實(shi)現圖像的無(wu)限自由(you)拉伸、壓縮、跨屏、漫游、疊加、畫中畫、畫外畫、并且每個(ge)解碼處理單元最高(gao)可達1920×1080全(quan)高(gao)清(qing)輸(shu)出。

3、豐富的(de)信號(hao)源(yuan)類型(xing)基本上(shang)涵蓋了目前市面上(shang)幾乎所有的(de)類型(xing)：其(qi)輸入信號(hao)包(bao)(bao)括CVBS、YPBPR、VGA、HDMI、DVI、DVI PLUS、DVI（HDCP）、3G-SDI、HD-SDI、HDBaseT、Fiber等(deng)；輸出信號(hao)則包(bao)(bao)含VGA、HDMI、DVI、DVI、3G-SDI、HDBaseT、Fiber等(deng)、在一定程度上(shang)真正的(de)實現了數模高(gao)清信號(hao)任(ren)意組合切換、并且每個通(tong)道可配(pei)置不同的(de)分辨率。

4、采用純硬件(jian)板卡(ka)式(shi)(shi)單(dan)(dan)路單(dan)(dan)卡(ka)結構單(dan)(dan)路板卡(ka)式(shi)(shi)設(she)計、安裝靈活方便，其(qi)(qi)輸(shu)入(ru)輸(shu)出板卡(ka)、控(kong)制(zhi)卡(ka)等主要模(mo)塊均為插卡(ka)方式(shi)(shi)設(she)計：并且擁有多種接(jie)口(kou)信(xin)號格式(shi)(shi)混入(ru)混出等功能，其(qi)(qi)中單(dan)(dan)卡(ka)單(dan)(dan)通道(dao)設(she)計可支持8×8、18×18、36×36、72×72、144X144等多類型多路數(shu)信(xin)號的配置規模(mo)。

5、矩陣采(cai)用分布式、節點化的設計方案、在(zai)一定(ding)程度上提高了液(ye)晶拼接墻顯(xian)示(shi)系統(tong)的穩(wen)定(ding)性(xing)，并且單點故障對整個(ge)大屏幕顯(xian)示(shi)系統(tong)而言并無多大的影響(xiang)、而且相對于(yu)傳(chuan)統(tong)PC架構控(kong)制系統(tong)而言其在(zai)真(zhen)正意義上實現熱插拔(ba)、低功耗、節能環保、安全可靠；

當然、分布(bu)式(shi)(shi)矩(ju)陣(zhen)(zhen)的優點遠非以上幾點，還有一些小編就不在(zai)這(zhe)一一列舉了(le)(le)。但就液晶(jing)拼(pin)接(jie)屏的用戶而言、能夠了(le)(le)解清楚以上幾點就足以滿足其選(xuan)購分布(bu)式(shi)(shi)矩(ju)陣(zhen)(zhen)了(le)(le)。除了(le)(le)在(zai)液晶(jing)拼(pin)接(jie)墻顯示系統(tong)中會使用到分布(bu)式(shi)(shi)矩(ju)陣(zhen)(zhen)外在(zai)一些多媒體系統(tong)中也能看見其身影。
