在高速公路的视频传输联网中,需要考虑的重点问题是在保证图像质量的前提下延长视频图像的传输距离以及充分利用通信系统提供的资源,灵活分配带宽。本文主要从压缩编码技术研究视频传输联网的关键技术。
In the video transmission network of the expressway, the key problem to be considered is to extend the transmission distance of the video image under the precondition of guaranteeing the image quality, and make full use of the resources provided by the communication system to allocate the bandwidth flexibly. This paper mainly studies the key technologies of video transmission networking from the compression coding technology.
