【摘要】 以MPEG-4视频标准和UDP协议为基础,提出一种适合目前嵌入式视频点播的传输方案。该系统以Linux作为操作系统,采用硬编码方式,把输入的TV视频信号或AV信号转换成MPEG-4码流输出到网络。讨论了系统的工作原理,着重阐述了系统软件模块的实现方法。研究结果表明,提出的关于MPEG-4视频流传输设计方案是切实可行的。更多还原

【Abstract】 This paper presents a transmission scheme which fits into the present embedded VOD(video on demand) by the MPEG-4 video standard and the UDP protocol.Taking the embedding Liux as the operation system and hard-coding as the method,it converts the input TV video signals or AV signals into MPEG-4 bit-stream and then transmits it to the network.This paper discusses about the principle of encoding server system,and specially expounds the realization of software modules of the system.The result shows that the design scheme is feasible on the transmitting of video stream of MPEG-4.更多还原
