摘要
本文设计了一种基于H.264视频压缩编码技术的网络视频服务器。硬件设计采用SA7111A芯片完成输入视频A/D转换;以TMS320DM642DSP芯片为核心硬件平台实现视频压缩编码;利用微处理器SA1110、以太网接口控制器RTL8139C及相应外围设备实现网络控制和传输。软件设计包括视频编码和网络传输控制两个模块。实测结果表明,在普通IP网络环境下,基于H.264的网络视频服务器较好地实现了视频实时编码和传输,同时具有清晰连续的图像质量。
A video server based on H.264 standard is designed and presented in this paper. The hardware of video server includes SA7111A which realizes video A/D transform, TMS320DM642 DSP which is used as the kernel hardware platform and realizes video coding, and MPU SA1110, Ethernet interface controller RTL8139C and some peripheral equipment which realize the network control. The software includes two modules： video coding and network transmission control. The experiment results show that the video server based on H.264 can completes video coding and real time transmission very well in the common IP internet condition, and the video performance is clear and smooth.
