【摘要】：隨著網(wǎng)絡(luò)技術(shù)的飛速發(fā)展和液晶顯示面板的不斷普及,生動(dòng)的影音視頻信息以其獨(dú)特的視覺感染力受到了越來越多的商家與客戶的青睞,在商務(wù)樓和商場(chǎng)中隨處可見各種形形色色的多媒體面板,各種各樣的節(jié)目為來往的行人提供了大量的信息,而這些信息的載體正是多媒體資源。目前在該行業(yè)內(nèi),相關(guān)從事多媒體播放的公司所制作的播放系統(tǒng)還比較老舊,特別是在多媒體資源的管理上,大部分采用的還是人工插拔SD卡的形式,無法做到便捷地更新多媒體節(jié)目。而隨著越來越多智能移動(dòng)終端的出現(xiàn)和計(jì)算機(jī)網(wǎng)絡(luò)的普及,使得多媒體自動(dòng)播放系統(tǒng)和管理系統(tǒng)必須做出革命性的改變。在上一代多媒體資源管理發(fā)布系統(tǒng)的基礎(chǔ)上,本文對(duì)其做了詳盡的分析和研究,提出了新的管理發(fā)布系統(tǒng)的開發(fā)原型。本文對(duì)新一代多媒體資源管理發(fā)布系統(tǒng)的研究和闡述,主要分為管理端和播放端兩塊。管理端將針對(duì)視頻、圖片和文字信息,根據(jù)用戶的權(quán)限,進(jìn)行便捷的管理和使用,還能夠直接通過RS232指令管理遠(yuǎn)程播放終端和發(fā)送多媒體節(jié)目。播放端重點(diǎn)放在多媒體資源的請(qǐng)求和資源調(diào)度上,為了減小傳輸造成的帶寬壓力,研究采用P2P分布式的存儲(chǔ)方式,達(dá)到降低帶寬符合的目的。本課題已實(shí)現(xiàn)了初步的系統(tǒng)原型,并在實(shí)驗(yàn)室環(huán)境中進(jìn)行了測(cè)試和調(diào)試,對(duì)于在真實(shí)網(wǎng)絡(luò)環(huán)境的使用,還需進(jìn)一步的測(cè)試。
[Abstract]:With the rapid development of network technology and the popularization of LCD panel, the vivid audio and video information is favored by more and more merchants and customers because of its unique visual appeal. A variety of multimedia panels can be found everywhere in business buildings and shopping malls. Various programs provide a great deal of information for pedestrians, and the carrier of these information is multimedia resources. At present, in this industry, the playback systems produced by the relevant companies engaged in multimedia broadcasting are still relatively old, especially in the management of multimedia resources, most of which are still in the form of manually plugging SD cards. Can not easily update multimedia programs. With the emergence of more and more intelligent mobile terminals and the popularity of computer networks, multimedia automatic playback systems and management systems must make revolutionary changes. On the basis of the previous generation of multimedia resource management and release system, this paper makes a detailed analysis and research on it, and puts forward the development prototype of the new management and release system. In this paper, a new generation of multimedia resource management and release system is studied and described, which is divided into two parts: the management end and the playback terminal. The management side will manage and use the video, picture and text information conveniently according to the user's authority, and can also directly manage the remote broadcast terminal and send multimedia programs through the RS232 instruction. In order to reduce the bandwidth pressure caused by transmission, P2P distributed storage method is adopted to reduce bandwidth compliance. The prototype of the system has been implemented and tested and debugged in the laboratory environment. Further testing is needed for the use of the real network environment.
