Network video encoder mainly provides video compression or decompression function to complete image data acquisition or restoration. At present, the popular image data compression based on MPEG-4 or H.264 transmits data and audio data processing through Internet network.

The work flow of network video encoder is to combine video and control to a computer network for transmission, and restore the original appearance of video signal at the network solution. The direct video signal can be obtained through hard network solution, and the control keyboard can also be connected to control the lower end equipment; Through the soft network solution, you can browse and control on the computer network. Upload the video signal at the front end and transmit the control signal at the back end. The down transmitted control signal can be used to control front-end equipment such as matrix picture processor alarm. When the multi-level center is sent to the general control center, it has strong advantages in inter city and inter provincial networking. Due to the diversity of matched equipment and different underlying protocols, the network coding and network solution directly purchased need to be used after secondary development.
