【摘要】 随着多媒体信息压缩技术和宽带网络技术的快速发展，通过网络传输高质量的多媒体信息已经成为信息技术领域研究的热点之一。同时嵌入式Linux系统的研究和应用也正在成为信息技术研究重点之一。本文设计的多媒体传输系统主要可以分成三部分：一是基于MPEG-2标准的多媒体信息编解码硬件系统、二是基于嵌入式Linux的多媒体信息发送系统、三是基于嵌入式Linux或计算机的多媒体信息接收系统。文中多媒体传输系统的框架和组成该系统的各个部分进行了详细的介绍。在整个系统的设计过程中应用了MPEG-2多媒体编码技术、TCP／IP传输技术、RTP协议、嵌入式Linux系统应用技术。文中对这些技术的主要部分都进行了较为详细地介绍。本文设计的基于嵌入式Linux系统的实时多媒体传输系统不仅是对多媒体压缩和网络传输技术的应用和研究，也是对嵌入式Linux系统应用技术的一次有意义的尝试，为进一步做研究打下一个良好的基础。更多还原

【Abstract】 With the rapidly development of multimedia signal compression and broadband networks technologies, methods of transmitting high-quality multimedia information via networks have become one hottest point of IT technologies. Researches and developments of Embedded Linux system technology are becoming another important IT technology. In this thesis, we present a real-time multimedia transmission system based on embedded Linux technology. There are three parts in the system, a pair of MPEG-2 standard codec, a transmitting system and a receiving system. We describe the whole system skeleton and principle and the design of each parts in detail. During the system design, we take advantages of these technologies, such as MPEG-2, TCP/IP, RTP and embedded Linux technology. These technologies are discussed in different chapters. To design and research a real-time multimedia transmission system based on embedded Linux not only combines multimedia signal compression technology and networks technology, but also explores the application of the embedded Linux technology. The content of this thesis might be helpful to develop the multimedia transmission technology.更多还原
