摘要
为了满足人们对视频处理系统高清、便携和远程可操作的需求,文章设计并实现了一个高清视频处理系统,它以TMS320DM8168 SOC为核心,将HD-SDI高清视频的采集、处理、压缩、存储、显示和千兆网络传输等功能集成为一体。文章对系统的硬件结构进行了简单介绍,对系统软件中的驱动程序部分进行了详细的介绍分析,并以相邻帧差法为例,使用本系统实现了对30帧频1 920×1 080高清视频中运动物体的检测,并且对系统的性能进行了全方位的测试。测试结果表明,本系统作为单片系统,不仅满足了视频处理系统高清、便携、可远程操作的要求,而且具有设计简单、扩展性好、处理能力强、算法可重构等优点。
In order to meet the requirement of high definition, portability and remote operation of the video processing system, a high definition video processing system based on TMS320DM8168 SOC is designed and implemented. With the system, the HD-SDI video can be captured, compressed, stored in the hard disk, displayed on LCD and transmitted via the network. The paper gives a brief introduction on the hardware structure. The embedded drivers are explained in detail. In order to test the system performance, the frame difference, which is used to detect moving objects, is implemented on the system. The results show that the SOC system not only has met the requirement of high definition, portability and remote operation, but also has the advantage of simple design, good expansibility and flexibility, strong processing ability and reconfigurable operation arithmetic.
