Abstract

A method for controlling network media information publication, an apparatus and a server are provided. More than one piece of network media information may be pre-downloaded. When a video is played, a stagnation event of the video is detected. When a stagnation event occurs, a frame picture related to the stagnation event is read. A degree of similarity between the frame picture and each piece of network media information is calculated. A piece of network media information having a highest degree of similarity with the frame picture is selected; and the network media information is displayed on a current playing interface. In this way, a click-through rate and a transformation rate of network media information, and the amount of attention given to network media information when a network bandwidth condition is not good can be increased.
