【摘要】：程序Web化在云計(jì)算的大背景之下已經(jīng)成為一種大的發(fā)展趨。Web程序相對(duì)于傳統(tǒng)應(yīng)用軟件形式的程序具有諸多優(yōu)勢(shì)，無(wú)需要安裝、跨平臺(tái)以及便于升級(jí)維護(hù)。交互視頻是一種當(dāng)用戶(hù)與視頻中出現(xiàn)的事物交互時(shí)就會(huì)自動(dòng)展示出相應(yīng)事物附加信息的新型多媒體。其應(yīng)用領(lǐng)域廣泛，如可以應(yīng)用于廣告領(lǐng)域、教學(xué)領(lǐng)域和網(wǎng)絡(luò)娛樂(lè)等。此前，本人所在實(shí)驗(yàn)室中的項(xiàng)目組曾與X公司合作完成了桌面版的交互式視頻系統(tǒng)。但由于桌面版的交互式視頻系統(tǒng)只能運(yùn)行在Windows系統(tǒng)下，還需要用戶(hù)下載安裝，從而限制了用戶(hù)使用。因此X公司根據(jù)市場(chǎng)反應(yīng)而提出的新的合作需求。據(jù)此，本人作為項(xiàng)目組主要成員參與了從需求到設(shè)計(jì)再到實(shí)現(xiàn)等整個(gè)過(guò)程。 在分析了舊版交互視頻編輯器的基礎(chǔ)上，，提出一種基于HTML5與RPC協(xié)議的交互視頻編輯器Web化設(shè)計(jì)方案。方案采用MVC架構(gòu)，前臺(tái)使用HTML5技術(shù)實(shí)現(xiàn)了視圖，服務(wù)端使用RPC、Java等技術(shù)實(shí)現(xiàn)了控制器，數(shù)據(jù)模型即視頻處理模塊依靠OPENCV實(shí)現(xiàn)。該方案綜合考慮了瀏覽器端、Tomcat服務(wù)器端和視頻處理模塊特點(diǎn)，均衡了各端負(fù)載，提高了系統(tǒng)的可靠性。通過(guò)Web交互視頻編輯器系統(tǒng)，用戶(hù)只需使用支持HTML5標(biāo)準(zhǔn)的瀏覽器即可編輯交互視頻而無(wú)需安裝任何插件。實(shí)驗(yàn)結(jié)果證明方案的可行性。 由于基于Web的交互視頻系統(tǒng)目前行業(yè)中還沒(méi)有，同時(shí)類(lèi)似基于Web的視頻應(yīng)用都是針對(duì)特定系統(tǒng)安裝插件實(shí)現(xiàn)的，因此可供借鑒的資料很少，開(kāi)發(fā)難度也因此加大。但這些困難都被一一攻克，并最終完成了基于Web交互視頻系統(tǒng)。本文所述內(nèi)容源自實(shí)踐具有實(shí)用性和創(chuàng)新性，對(duì)于交互視頻商業(yè)化具有一定的促進(jìn)作用，對(duì)于后來(lái)者開(kāi)發(fā)類(lèi)似基于Web的視頻系統(tǒng)應(yīng)用具有一定的參考價(jià)值。
[Abstract]:Under the background of cloud computing, program Web has become a big trend of development. The web program has many advantages over the traditional application software, no need to install, cross-platform and easy to upgrade and maintain. Interactive video is a new type of multimedia that automatically displays the additional information of the corresponding objects when the user interacts with the objects in the video. It can be used in many fields, such as advertising, teaching and network entertainment. Previously, my lab project team and X Company completed the desktop version of the interactive video system. But because the interactive video system of desktop version can only run under Windows system, it also needs the user to download and install, which limits the user's use. Therefore X company according to the market response and proposed the new cooperation demand. Accordingly, as the main member of the project team, I participated in the whole process from requirement to design to implementation. Based on the analysis of the old interactive video editor, an interactive video editor Web design scheme based on HTML5 and RPC protocol is proposed. The scheme adopts MVC architecture, the foreground uses HTML5 technology to realize the view, the server uses RPC,Java technology to realize the controller, and the data model, that is, the video processing module, is realized by OPENCV. This scheme considers the characteristics of the browser side Tomcat server and video processing module synthetically, balances the load of each end, and improves the reliability of the system. Through the Web interactive video editor system, users can edit interactive video without installing any plug-in by using a browser that supports the HTML5 standard. The experimental results show that the scheme is feasible. Because there is no interactive video system based on Web and video applications based on Web are implemented for special system installation plug-in, so there is little data to be used for reference, and the difficulty of development is increased. But these difficulties have been overcome one by one, and finally completed based on Web interactive video system. The content mentioned in this paper is practical and innovative from practice, which can promote the commercialization of interactive video to a certain extent, and has a certain reference value for the latecomers to develop video system applications similar to that based on Web.
