Publish control method and system of network media information, device and server

The invention discloses a publish control method and system of network media information, a device and a server. The method comprises that more than one piece of network media information is pre-downloaded; a video stagnation event is monitored when video is played; when the stagnation event occurs, a frame picture related to the stagnation event is read; the similarities between the frame picture and different pieces of network media information are calculated; and the network media information of the highest similarity to the frame picture is selected, and displayed in a present play interface. Thus, the clicking rate, the conversion rate and the attention degree of network media information when the network bandwidth is not ideal can be improved, and waste of machine and network resource caused by blind publish amount improvement of a publish part can be reduced.
