【摘要】 论文的工作是基于“流媒体网络广播系统”项目。在调研和消化多套国内外相关实验平台系统的基础上，研究开发了基于ARM9处理器和嵌入式Linux操作系统的多功能实时计算机处理系统，并且根据实际需要构建了此系统的软硬件平台。流媒体网络广播系统是当前IT领域比较热门的前沿技术，正是因为这前沿技术使得实际构建出的系统功能强大、体积小、成本低、具有相当强的可扩展性，完全能够取代当前传统广播系统中广泛采用的模拟信号传输方式，同时也更好解决了以往这种结构带来的价格昂贵、体积庞大、系统利用率低等诸多劣势。本文设计开发了基于AMR-Linux的流媒体网络广播平台，该系统基于SamsumgS3C2410处理器，采用嵌入式ARM-Linux操作系统，通过HTTP协议传输流媒体，利用MP3标准实现对音频的解码，从而支持流媒体网络广播功能。本论文设计了系统的软件部分，包括底层软件BootLoader、ARM-Linux操作系统、根文件系统、网卡的驱动程序等并提出了下一步工作的建议和设想。基于ARM-Linux系统的软件设计方法是本论文的重点和难点，也是论文的核心内容。流媒体网络广播系统已经经过测试，实际的应用效果表明该系统是可行的也是可靠的，同传统的广播系统相比，体现出了明显的优势。更多还原

【Abstract】 The paper is based on the project of streaming media network broadcast system. After investigate and research domestic and overseas relevant experiments platforms, a multi-functional and real-time computer system based on ARM9 core and embedded Linux OS is established. At present, streaming media network broadcast system is major IT.domains, and it makes the actual equipment with a lot of advantages such as powerful function, small size, low cost and strong expansibility. And it can completely replace the tradition broadcast system which is based on the transmit mode of simulation signal.The design of this paper is based on the streaming media network broadcast platform with ARM-Linux OS. Base on Samsumg S3C2410 Processor and embedded ARM-Linux, the system broadcast streaming media with HTTP protocol. The software system integrates Bootloader, ARM-Linux Os, root filesystem, the driver of network card . Finally, and the suggestions and expectations are given.The designs of the software and hardware in the ARM-Linux system are most important and difficult in this paper. The testing result of the final system implemented indicates that the experience and method are reliable and practical, and the system is with a lot of advantages compared with tradition broadcast system.更多还原
