移动终端流媒体播放器的研究
|
摘要
本文研究设计了一种基于移动终端的流媒体播放器。该流媒体播放器采用了嵌入式Linux操作系统和Xscale PXA255硬件平台，使用流媒体技术，并且利用Xvid开源的MPEG4视音频解码算法，应用了无线以太网环境。利用本流媒体播放器可以进行流媒体的视频点播收看等业务，具有小型化，低功耗，稳定可靠，便于携带等特点。
第一章综合论述了本文研究工作的意义及内容，简要介绍了流媒体技术，同时给出了流媒体播放器的发展现状。
第二章介绍了移动终端流媒体播放器开发所用的相关技术。包括流媒体实时传输控制协议、多媒体视音频压缩协议——MPEG4以及无线以太网技术。
第三章总体介绍了移动终端流媒体播放器的硬件设计方案。
第四章论述了移动终端流媒体播放器的软件分析和设计，包括总体框架和播放系统通信流程及其状态控制，以及各模块包括网络接收模块、视频解码绘屏模块、音频解码回放模块的分析和设计。
第五章详细阐述了移动终端流媒体播放器的MPEG4视频解码算法的实现。
第六章讨论了移动终端流媒体播放器的软件的优化和性能测试工作。
第七章给出了本课题研究的主要进展及结论，并对系统进一步的工作进行了展望。
In this dissertation, a mobile terminal media player is designed. This system is developed based on high performance embedded processor XScale PXA255. The MPEG-4 technology,embedded Linux, and stream media technology are used in designing the system. By this Media player, we can use the VOD all over the network.The media player has the characters of miniaturization,low power,stable and portable.
In chapter 1, a comprehensive description about the significance of the researchwork is given. The current research status of multimedia player, and stream media technology are also described.
In chapter 2, a description about the programming techniques is given. The multimedia compressing technology — mpeg4, the stream media real-time transfer protocol and the technology about wireless network are also discussed in detail.
In chapter 3, the hardware system design is discussed.
In chapter 4, a discussion about the software system design is given, including the total structure of the system design, communication flow and control of the system states, and also including all the functional modules design, like network receiving module, video decoding and displaying module, audio decoding and displaying module.
In chapter 5, the Mpeg-4 video decoding is presented in detail.
In chapter 6, descriptions about the software optimiziation and software testing are given.
In chapter7, the current research status and the main research conclusion are summarized. The prospect of further research is also proposed.
