摘要
针对目前监控方案的主流压缩算法存在的不足,提出一款嵌入式Web视频监控系统的设计方案。系统以TI高速双核信号处理器TMS320DM6446和嵌入式linux操作系统为平台,通过DSP端进行视频信号的H264数据压缩,在ARM端采用流媒体技术通过网络传播实时视频流。详细论述系统的总体设计和软件设计,列出Davinci技术的优势。结果表明,在Davinci技术的支持下,采用压缩比更高的H264压缩算法在DSP端进行视频编码,既能保证视频质量,还能提高算法的运行速度。
For the mainstream compression algorithm＇s shortcomings of the current monitoring program, an embedded web video monitoring system is put forward. Based on TI＇s high-speed dual-core TMS320DM6446 and embedded linux operating system platform, the H264 video compression is done in DSP side, and the real-time video streaming is disseminated through network by streaming media technology in ARM-side. The overall design and software design are discussed in detail and Davinci technology advantage is listed. The results show that video encoding using H264 higher compression algorithms in DSP side by the Davinci technology can ensure video quality and improve the algorithm speed.
