【摘要】：隨著互聯(lián)網(wǎng)的發(fā)展,互聯(lián)網(wǎng)電視未來的發(fā)展的趨勢(shì)無可爭(zhēng)議,電視廠商紛紛推出高清視頻內(nèi)容,如果高清的視頻內(nèi)容繼續(xù)采用傳統(tǒng)的客戶端服務(wù)器模式傳輸,會(huì)給企業(yè)的服務(wù)器帶來巨大的負(fù)載,企業(yè)需要購買更快的網(wǎng)絡(luò)寬帶才可以解決,否則會(huì)影響網(wǎng)絡(luò)傳輸?shù)乃俣?用戶也會(huì)因?yàn)榫W(wǎng)速太慢而選擇更換節(jié)目或者放棄觀看。因此,能夠快速播放高清視頻內(nèi)容成為目前一個(gè)亟待解決的問題。本文針對(duì)在PC端的Peer-to-Peer(P2P)文件分發(fā)技術(shù)進(jìn)行研究,設(shè)計(jì)了一套基于Android平臺(tái)的P2P視頻播放系統(tǒng),使用P2P技術(shù)能降低企業(yè)寬帶壓力提高服務(wù)質(zhì)量,下載的人越多,下載速度也就變得越快。系統(tǒng)主要由客戶端、Web服務(wù)器和Tracker服務(wù)器三大子系統(tǒng)組成。根據(jù)用戶需求對(duì)系統(tǒng)進(jìn)行了功能分析和非功能性分析,設(shè)計(jì)了系統(tǒng)的總體功能模塊,重點(diǎn)介紹了三大子系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)。通過分析BitTorrent協(xié)議,搭建了一個(gè)基于BitTorrent協(xié)議的Tracker服務(wù)器,并成功將其與視頻播放系統(tǒng)進(jìn)行了整合,具有種子制作和記錄客戶端之間文件共享的狀態(tài)等功能�？蛻舳酥饕�(fù)責(zé)與Tracker服務(wù)器和同等客戶端之間通信進(jìn)行下載文件,通過調(diào)用Vitamio的接口對(duì)下載的文件進(jìn)行播放。介紹了 Web服務(wù)器子系統(tǒng)的整體框架和詳細(xì)設(shè)計(jì),以及相應(yīng)的數(shù)據(jù)庫結(jié)構(gòu)設(shè)計(jì),包括用戶管理、電影管理、積分管理、廣告推送等功能模塊,主要的功能模塊是對(duì)Tracker服務(wù)器制作的種子進(jìn)行發(fā)布。最后在局域網(wǎng)的環(huán)境下對(duì)客戶端進(jìn)行了功能測(cè)試工作,測(cè)試單獨(dú)的客戶端節(jié)點(diǎn)下載的速度和多個(gè)客戶端節(jié)點(diǎn)下載速度。通過實(shí)驗(yàn)數(shù)據(jù)證明了本系統(tǒng)達(dá)到了下載人數(shù)越多,下載速度更快的要求,測(cè)試的結(jié)果基本達(dá)到了設(shè)計(jì)的要求,能夠滿足企業(yè)降低寬帶成本提高用戶的服務(wù)質(zhì)量,企業(yè)還可以通過高清視頻播放作為互聯(lián)網(wǎng)電視的入口,分析用戶操作行為挖掘出更多的價(jià)值。
[Abstract]:With the development of the Internet, the trend of the future development of Internet TV is indisputable. TV manufacturers have introduced high-definition video content one after another. If the high-definition video content continues to be transmitted in the traditional client-server mode, Will bring a huge load on the server of the enterprise, enterprises need to buy faster network broadband to solve, otherwise it will affect the speed of network transmission; users will also choose to change programs or give up watching because the network speed is too slow. It is an urgent problem to play high definition video content quickly. In this paper, a P2P video playback system based on Android platform is designed, which is based on the research of Peer-to-Peer P2P file distribution technology in PC. Using P2P technology can reduce enterprise broadband pressure to improve the quality of service, the more people download, The system is mainly composed of three subsystems: client web server and Tracker server. According to the user demand, the system is analyzed in function and non-functional, and the overall function module of the system is designed. This paper mainly introduces the design and implementation of the three subsystems. By analyzing the BitTorrent protocol, a Tracker server based on BitTorrent protocol is built, and it is successfully integrated with the video playback system. The client is mainly responsible for downloading files with the Tracker server and the equivalent client. This paper introduces the whole frame and detailed design of the Web server subsystem, and the corresponding database structure design, including user management, movie management, integral management, etc. The main function module is to release the seed produced by Tracker server. Finally, the client is tested in the LAN environment. Test the download speed of individual client node and multiple client node download speed. The experimental data prove that the more the number of download, the faster the download speed, the test results basically meet the requirements of the design. It can meet the needs of enterprises to reduce the cost of broadband and improve the quality of service of users. Enterprises can also use high-definition video play as the entry point of Internet TV, and analyze the user's operation behavior to find out more value.
