【摘要】： 近年來,隨著移動互聯(lián)網(wǎng)的快速發(fā)展,越來越多的移動流媒體系統(tǒng)不斷涌現(xiàn)。而3G網(wǎng)絡擁有更高的數(shù)據(jù)傳輸速率和數(shù)據(jù)業(yè)務支撐能力,3G運營商不僅可以向用戶提供高質量的語音業(yè)務,還能夠提供高速率的流媒體業(yè)務。因此3G網(wǎng)絡能為移動流媒體業(yè)務發(fā)展提供更強有力的網(wǎng)絡支撐。 本文首先探討移動流媒體系統(tǒng)的發(fā)展現(xiàn)狀,介紹目前數(shù)款國內外流行的移動流媒體系統(tǒng)的特點,總結目前移動流媒體業(yè)務發(fā)展所面臨的三個問題:技術成熟性問題、流媒體節(jié)目內容問題和運營模式問題。針對這些問題,本文提出一種針對移動流媒體系統(tǒng)的架構,設計出一款面向3G應用的移動流媒體系統(tǒng)。該系統(tǒng)運行在Windows Mobile操作系統(tǒng)上,主要基于3G無線通信技術,并輔以應用越來越廣泛的WiFi技術,除提供視頻的直播、點播功能外,還在移動流媒體系統(tǒng)上實現(xiàn)了較具特色的時移電視功能和錄像訂制、播放功能。 接著本文對所提出的移動流媒體系統(tǒng)中采用的關鍵技術:流媒體編碼、流媒體服務器、流媒體錄制和存儲等方面進行詳細的介紹。本文隨后提出具有一定創(chuàng)新價值和應用價值的解決方案。在闡述系統(tǒng)的業(yè)務邏輯架構、網(wǎng)絡拓撲結構、總體技術架構后,本文以模塊為單位對系統(tǒng)的設計進行詳細的分析,重點描述了系統(tǒng)的主要部分:手機客戶端中直播、點播、時移電視、錄像訂制模塊,以及服務器端中錄像訂制、廣告插播/管理、負載均衡模塊的設計思想和技術實現(xiàn)細節(jié)。 最后,本文對系統(tǒng)的關鍵組成部分:流媒體發(fā)布服務器以及負載均衡模塊進行測試。本文結尾對研究課題的實際意義和創(chuàng)新點進行了總結,并提出進一步研究的方向。
[Abstract]:In recent years, with the rapid development of mobile Internet, more and more mobile streaming media systems are emerging. 3G network has higher data transmission rate and data service support capability. 3G operators can not only provide high quality voice services to users, but also provide high speed streaming media services. Therefore, 3G network can provide stronger network support for the development of mobile streaming media service. This paper first discusses the development status of mobile streaming media system, introduces the characteristics of several popular mobile streaming media systems at home and abroad, and summarizes the three problems facing the development of mobile streaming media business: technology maturity. Streaming media program content problem and operation mode problem. Aiming at these problems, this paper proposes a mobile streaming media system architecture and designs a mobile streaming media system for 3G applications. The system, which runs on Windows Mobile operating system, is mainly based on 3G wireless communication technology, supplemented by WiFi technology, which provides video broadcasting and on-demand functions. The features of time shift TV and video customizing and playing are also realized in mobile streaming media system. Then this paper introduces the key technologies used in the mobile streaming media system, such as streaming media coding, streaming media server, streaming media recording and storage, etc. This paper then put forward a certain innovative value and application value of the solution. After explaining the system's business logic structure, network topology structure and overall technical framework, this paper analyzes the system design in detail with modules, and describes the main parts of the system: live broadcast, on-demand broadcasting in the mobile phone client. The design ideas and technical implementation details of time-shift TV, video customization module, video customization on server side, advertisement broadcast / management, load balancing module. Finally, this paper tests the key components of the system: streaming media publisher and load balance module. At the end of this paper, the practical significance and innovation of the research are summarized, and the direction of further research is put forward.
