The network digital matrix is a product specially designed for the front-end equipment, which is all the network digital video stream input, and is output to the monitoring center for outputting the video wall, and is used to complete functions such as output, switching, storage, forwarding, and remote control of video.
The network digital matrix is not the same as the conventional matrix. The signal input of the network digital matrix is ​​through the network (LAN, Internet or other network) to transmit the compressed audio and video signals to the network matrix. The output of the network digital matrix is ​​still digital signals. It can also be a decoded analog signal. The main function of the network digital matrix is ​​to receive audio and video signals from multiple input points and selectively output it to other storage devices, display devices or network devices.
The advantage of the network digital matrix is ​​that it can be completely implemented in software, can be expanded arbitrarily, and can be flexibly configured. It can implement distributed design and layout of equipment so as to make better use of network resources.
The disadvantage of the network digital matrix is ​​that the real-time performance of audio and video transmission cannot be compared with the analog matrix, which depends on the encoding speed of the remote host and the transmission efficiency of the network module. The effect of the transmission depends on the encoding module and the network transmission module.
