Technical Field

The utility model relates to a distributor technical field specifically is a one advances two play digital video distributor.

Background

A video distributor is a device that distributes a video source into multiple video signals so that the video output can be viewed without distortion or loss of definition. That is, the source device inputs a video signal to the video frequency divider through the cable, and the video frequency divider can distribute one path of input video signal into multiple paths of signals and output the multiple paths of signals to the subsequent device. In special applications such as medical imaging and industry, a computer system often needs to be connected with a plurality of display terminals. Since these Display terminals may be of the same type or different types, and sometimes all Display terminals are required to Display the same picture, it is necessary to develop a video distributor capable of simultaneously distributing one Display Port signal to different devices.
