摘要:
针对高清视频信息的网络化传输存在高计算复杂度和图像还原质量较差的问题,提出一种基于分级缩放技术的视频网络化传输方案. 该方案中,在发送端对视频信息进行分级缩小处理,经网络传输后,在接收端根据用户需求对视频信息进行分级放大处理. 仿真结果表明该技术方案能够适应现有网络带宽条件,无需改变现有网络布局及路由交换设备等基础设施即可工程化应用.
Abstract:
A video network transmission scheme based on graded scaling was proposed for the problem of high computational complexity and poor reconstructed image quality in network transmission of high-definition video information. In the proposed scheme, the video information at the sender is processed by graded reduction. After the network transmission, the receiver’s video information is processed by graded magnification according to user’s needs. The simulation results show that the proposed technology can adapt to the existing network bandwidth conditions, realizing engineering application without changing the existing network layout, routing and switching equipment, and other infrastructure.
