摘　　要：为了设计一种功能丰富、易于扩展的多媒体处理系统,根据多媒体系统现状及发展趋势,制定了基于嵌入式Linux以及OMAP3530处理器为核心的系统设计方案,该系统具有多媒体模块、网络模块、显示模块及人机交互模块等。在此基础上进行了系统的硬件、驱动及应用层设计,软件平台在Linux内核2.6.28的基础上进行驱动的开发以及编解码算法的移植。实验表明,该系统具有功能多样化、技术一体化、系统集成化等一系列特点。针对不同的用户需求,可进行功能重组,对厂商和终端用户而言,将更加灵活方便,并且具有良好的应用前景。A multiple media system，which was feature-rich and easy to be expanded，was designed and realized. According to the research status and development trend of multiple media system，a scheme，taking OMAP3530 processor as the core of the hardware，was designed based on embedded Linux. The system was composed of multiple media processing module，display module，network module，and Human Computer Interaction（HCI） module. On this basis，the hardware，relative drivers and application layers were designed. The hardware drivers，encoding and decoding algorithms，and software were designed in the environment of Linux 2.6.28 kernel. The experiment results showed that the multiple media system was multi-functional，high-tech-combined，system-integrated and network based. It is an integrated platform with strong scalability and could be functionally reorganized for different users and manufacture. The flexibility and convenience make it a good application prospect in multiple media and communication system.
