【摘要】：近年来,随着我国经济以及通信业务的快速发展,第三代移动通信网络被广泛的应用在人们的日常生活中；同时,嵌入式技术以其低成本、低功耗、小体积、高稳定性和内核可裁剪性等特点,广泛的进入了通讯、网络、工控、医疗、电子等行业中；而多媒体做为传递文字、声音、图像和图形等信息的载体,早已成为了人们日常生活中的一部分。本文的研究课题就是把以上三个方面的内容结合起来：3G网络、嵌入式系统和多媒体。在3G无线网络环境下,嵌入式设备上,实现了多媒体的编码采集、网络传输以及解码播放,并在此基础上实现了3G嵌入式图像传输系统。 3G嵌入式图像传输系统采用OMAP3530处理器,在功能上实现了CDMA2000无线上网、在线实时播放、线下本地播放、自动下载本地文件等功能。服务器能控制客户机在什么时候播放什么内容,从而解决了市场上现有的流媒体播放设备更新播放内容困难以及各个客户机之间播放不同步等问题。项目开发经过了前期的选题、市场调研、技术分析等阶段,现在已经进入试验阶段且运行测试效果良好。
[Abstract]:In recent years, with the rapid development of economy and communication services in our country, the third generation mobile communication network has been widely used in people's daily life, at the same time, embedded technology with its low cost, low power consumption, small volume, Features such as high stability and tailoring of the kernel are widely used in the fields of communication, network, industrial control, medical treatment, electronics and so on, while multimedia is used as the carrier of information such as text, sound, image and graphics, etc. It has long been a part of people's daily lives. The research topic of this paper is to combine the above three aspects together: 3G network, embedded system and multimedia. In the 3G wireless network environment, the multimedia coding collection is realized on the embedded equipment. On the basis of network transmission and decoding and playing, a 3G embedded image transmission system is implemented. The 3G embedded image transmission system uses OMAP3530 processor to realize the functions of CDMA2000 wireless internet access, online real-time playback, offline local playback, automatic downloading of local files, etc. The server can control when and when the client plays what content. In order to solve the problems such as the difficulty of updating and playing content of the existing streaming media playback equipment in the market and the non-synchronization of the playback among the various clients, the project development has gone through the earlier stage of selected topics, market research, technical analysis, and so on. Now it has entered the experimental stage and runs the test well.
