摘要
目前的视频导播系统一般由视频处理装置和专用硬件切换矩阵构成,这种导播系统可靠性很差。为了解决此问题,提出了一种基于Linux的视频软导播系统的设计。该软件系统由内核层网络驱动、应用层的指挥控制界面以及内核层与应用层之间的通信三个主要部分构成。与硬件导播系统相比,软导播系统实现了硬件通用化、布线网络化,该方法已成功应用于车载指挥控制系统中。
The current video director system is made up by video processing equipment and hardware switch matrix. Its reliability is poor. In order to solve this problem ,Linux-based design of video soft direction system proposed. The system is made of kernel network drive ,command control interface in application layer and communication of kernel and application layer. Compared with hardware director system, this system realizes hardware universal, wiring network, and this method is successfully deployed in command and control system of vehicle.
