Video monitoring system, and medium flow transmitting control device and method in the video monitoring system

The present invention discloses a video monitoring system, and medium flow transmitting control device and method in the video monitoring system. In the present invention, control layer equipment is connected with a plurality of bearing layer equipment. Therefore, when the condition of any bearing layer equipment changes into abnormal, the control layer equipment can be used for detecting according to the conditions of a plurality of bearing layer equipment, and is used for selecting the bearing layer equipment in a normal condition in the plurality of bearing layer equipment to realize the colony control tactics of medium flow transmission. Another bearing layer equipment in a normal condition is randomly selected to ensure that the medium flow transmission between the front-end equipment and a CE can not be cut, and thus, the reliability of the medium flow transmission can be improved.
