【摘要】： 近年来,随着移动互联网的快速发展,越来越多的移动流媒体系统不断涌现。而3G网络拥有更高的数据传输速率和数据业务支撑能力,3G运营商不仅可以向用户提供高质量的语音业务,还能够提供高速率的流媒体业务。因此3G网络能为移动流媒体业务发展提供更强有力的网络支撑。本文首先探讨移动流媒体系统的发展现状,介绍目前数款国内外流行的移动流媒体系统的特点,总结目前移动流媒体业务发展所面临的三个问题:技术成熟性问题、流媒体节目内容问题和运营模式问题。针对这些问题,本文提出一种针对移动流媒体系统的架构,设计出一款面向3G应用的移动流媒体系统。该系统运行在Windows Mobile操作系统上,主要基于3G无线通信技术,并辅以应用越来越广泛的WiFi技术,除提供视频的直播、点播功能外,还在移动流媒体系统上实现了较具特色的时移电视功能和录像订制、播放功能。接着本文对所提出的移动流媒体系统中采用的关键技术:流媒体编码、流媒体服务器、流媒体录制和存储等方面进行详细的介绍。本文随后提出具有一定创新价值和应用价值的解决方案。在阐述系统的业务逻辑架构、网络拓扑结构、总体技术架构后,本文以模块为单位对系统的设计进行详细的分析,重点描述了系统的主要部分:手机客户端中直播、点播、时移电视、录像订制模块,以及服务器端中录像订制、广告插播/管理、负载均衡模块的设计思想和技术实现细节。最后,本文对系统的关键组成部分:流媒体发布服务器以及负载均衡模块进行测试。本文结尾对研究课题的实际意义和创新点进行了总结,并提出进一步研究的方向。
[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.
