中文摘要：

以数字信号处理（DSP）为硬件平台,对嵌入式视频软件系统的设计与实现进行了研究。提出了采用DSP核＋DSP/BIOS方案进行系统设计。在嵌入式实时操作系统DSP/BIOS的基础上,通过达芬奇技术分别对系统中的视频采集、H.264编/解码器、网络传输、显示等各个软件模块进行设计。解决了低码率高清晰度实时视频处理及传输的问题。经过系统测试,实现功能需求。系统具有高性能低成本的特点,广泛适用于各类监控、实时视频传输场合。

英文摘要：

Using DSP as the hardware platform, software design and implementation of embedded video system were studied. The scheme of DSP core ＋ DSP/BIOS program was proposed. Based on embedded real-time operating system DSP/BIOS, the DaVinci technology was used to design respectively video capture, H. 264 encoding/decoding devices, network transmission, display and other software modules. The design solved the problem of video processing and real- time transmission with low bit rate and high-definition. After testing, all functions were realized. The system has high- performance and low-cost, can be widely applied in monitoring and real-time video transmission.
