| 摘 要： | 本文介绍了基于H.264算法的网络视频传输系统的实现方案。该方案采用目前最新的视频压缩标准——H.264作为视频编解码算法，i．MX27作为系统的中心处理器，嵌入式Linux作为操作系统，RTP／UDP作为网络传输协议，实现了视频实时的在网络上传输。系统运行结果表明：该系统可以在Internet上实现视频的实时传输，显示帧率为10帧／秒以上（CIF格式）。除此之外，为了保证视频信息在传输过程中的安全性，在压缩视频的过程中，给信息提供了加密功能。本课题研究的基于H264视频编码算法的网络视频传输系统可以实现30帧／秒的视频信息传输效果。

| Abstract: | In this paper, an embedded Network Video Transmission System based on H.264 is proposed. In this system, the latest video compression standards-H.264 is used as video codec algorithm, the i.mx27 is used as the center processors of the system, embedded Linux is used as the operating system and RTP/UDP is used as the network transmission protocol. The paper introduces the design way and the frame of the system. The test results of the system show that the proposed system can support a real-time video transmission in intemet with a display frame rate of 30fps （ClF Format）. In addition, in order to ensure the security of the video information in the transmission, the system provides the encryption to the information in the process of compressing. |
