Abstract: The present disclosure discloses a pre-roll advertisement playing method, a terminal, and a video server, and relates to the field of multimedia technologies. The method includes: after detecting a play operation of an offline video, determining a current network connection status of a terminal; when the terminal is in a first connection state, determining, among multiple pre-roll advertisements obtained by the terminal, a specified pre-roll advertisement corresponding to the offline video; and playing the specified pre-roll advertisement in a process of playing the offline video. When playing an offline video in a non-WiFi connection state, the terminal may additionally play a pre-roll advertisement. Therefore, an audience range of the pre-roll advertisement is expanded, and an application range is relatively wide.

Abstract: Embodiments of the present invention disclose a push information pre-selecting method and apparatus. The method includes: based on historical push data of push information including a plurality of push information items, determining a feature for calculating a predicted value, and a weight corresponding to the feature; calculating a standard deviation of the feature; determining a fluctuation probability of the standard deviation; calculating the predicted value based on the weight, the standard deviation, and the fluctuation probability, the standard deviation and the fluctuation probability being used for calculating a fluctuation value for correcting the weight; based on the predicted value, selecting push information items satisfying a preset condition; and pushing the selected push information items to a target user.
