以混合矩阵为核心的视频汇聚传输应用方式受设备机框尺寸等因素制约，难以实

The video aggregation transmission application mode with the hybrid matrix as the core is restricted by factors such as the size of the equipment frame, and it is difficult to achieve the input and output aggregation requirements of more than 320 video signals. It is only suitable for a single command site with a fixed number of video signal sources, and it is difficult to meet the needs of a large number of signal aggregation and switching across command sites due to physical link limitations.

The video convergence transmission application mode with hybrid matrix as the core is restricted by the size of equipment frame and other factors, so it is difficult to meet the input and output convergence requirements of more than 320 video signals. It has the disadvantages of limited signal capacity, difficult expansion, complex design and difficult implementation. It is only suitable for single command places with a fixed number of video signal sources, Limited by physical links, it is difficult to meet the needs of a large number of signal aggregation and exchange across command sites

The application mode of video convergence transmission with hybrid matrix as the core is restricted by the size of equipment frame, etc., and it is difficult to meet the input and output convergence requirements of more than 320 channels of video signals. There are some shortcomings such as limited signal capacity, difficult expansion, complex design and difficult implementation, etc. It is only suitable for a single command place with a fixed number of video signal sources, and it is difficult to meet the needs of large number of signal convergence and exchange across command places due to the limitation of physical links.
