摘要
设计了在Linux操作系统上实现H.264视频编码的数字视频服务器(DVS)监控系统,该监控系统处理器采用TI公司高性能DaVinci DM6446,内嵌ARM和DSP双核结构,在ARM端完成驱动开发,如视频芯片SAA7114驱动的开发,网卡芯片KS721BL驱动的开发;在DSP端实现H.264实时编码算法.实时监控测试表明:视频图像质量良好.
The paper introduces the H.264 encoder implementation of digital video systems(DVS) in the Linux operating system.TI high performance DaVinci DM6446 digital media processor is adopted with embedded ARM and C64x+dsp double core.Driver development is realized on the ARM side such as SAA7114 video decoder driver,and real time H.264 video encoder on the DSP side.Real surveillance tests show the quality of visual image is satisfactory.
