【摘要】 Internet的迅猛发展使流媒体业务正日益普及,同时相关的流媒体技术也随之发展。流媒体技术的核心是流媒体服务器,本课题主要是以流媒体服务器系统为核心进行研究与讨论。HI3510是一款基于ARM9、DSP双处理器内核、支持AVC/H.264高性能通信媒体处理器,可广泛应用于实时视频通信等。DM6446(达芬奇)是美国德州仪器公司最新推出的嵌入式视频系统芯片,支持多媒体编解码器、应用编程接口、框架与开发工具等。本论文中的实验都是在以这两个芯片为核心的开发板上进行的。本文首先对嵌入式流媒体的相关技术进行了阐述,主要包括实时传输协议(RTP)、实时传输控制协议(RTCP)、实时流协议(RTSP)、资源预留协议(RSVP)、会话发起协议(SIP)、H.264编码方式和DirectShow开发平台。然后,介绍了一个基于RTSP/RTP的流媒体服务器在H13510上的实现。主要包括了几个方面:开发环境的配置,服务器的设计与分析,在确定了服务器的整个框架之后,编程实现了RTSP、RTP和取码流三个模块,并给出了测试结果。其次,将第一个服务器程序从H13510到DM6446进行移植,主要给出了两个系统不同部分的介绍,给出了相关的实现,并给出了测试结果。最后介绍了一个基于SIP协议的嵌入式流媒体系统的实现。同样介绍了开发环境的配置,系统框架的确定,系统模块的划分,各个模块的实现。更多还原

【Abstract】 With the rapid development of Internet, Streaming Media business become popular. At the same time, the related Streaming Media Technology developes with it. The key of the Streaming Media Technology is Streaming Media Server. The issue mainly researches and discusses with the Streaming Media Server System as the core.HI3510 is high-performance media and communications processors based on ARM9 and DSP dual-processor core and supporting AVC/H.264, which can be widely used in the fields such as real-time video communication etc.. DM6446 (Davinci) which is the new embedded video system-on-chip launched by USA Texas Instruments supporting media codec, application programming interface, frameworks and development tools. In this paper, the experiment is performed on development boards with the two chips being the core. Firstly, correlative technology of embedded streaming media is explained, including Real time Transport Protocol(RTP), RTP control protocol(RTCP), Real Time Streaming Protocol(RTSP), Session Initiation Protocol(SIP), H.264 coding and Direct Show Development Platform.Then, it introduces the implementation of Streaming Media Server based on RTP / RTSP on HI3510. It mainly includes the following several aspects: the configuration of development environments, the design and analysis of server programme, the implementation of three modules RTSP, RTP and acquiring bitstream after determining the whole framework of the server, and demonstration of experiment results.Secondly, the first server program was transplanted from HI3510 to DM6446.The main differences of system program and relevant realizations and testing results were given in this paragraph.Finally, this paper demonstrated a Embedded Streaming Media System Program realization based on SIP protocol. The development environment was configured and a system framework was esta blished and system modules were designed and program was coded.更多还原
